 Android ActionBarCompat-Basic Sample
-==============================
+===================================
 
-This sample shows you how to use ActionBarCompat to create a basic Activity which
-displays action items. It covers inflating items from a menu resource, as well as adding
-an item in code. Items that are not shown as action items on the Action Bar are
-displayed in the action bar overflow.
+This sample shows you how to use ActionBarCompat to create a basic Activity
+which displays action items. It covers inflating items from a menu resource,
+as well as adding an item in code.
+
+Introduction
+------------
+
+Android 3.0 introduced the “action bar” control, a toolbar that is expected
+to be present in most types of applications. This control identifies the user
+location, and provides user actions and navigation modes.
+Using the action bar offers your users a familiar interface across applications
+that the system gracefully adapts for different screen configurations.
+
+Instantiating an action bar can be done by using the [ActionBar][1] API provided
+in API 11 or above. Support for older devices is provided by the
+[support library’s ActionBar][2] implementation, compatible back to API 7.
+This sample demonstrates using the support library APIs.
+
+Using an ActionBar with the support library requires the following steps:
+
+1. Create your activity by extending ActionBarActivity.
+2. Use (or extend) one of the Theme.AppCompat themes for your activity.
+
+Once this is done, action items will be created for any options menu items that
+would otherwise be created during when `[onCreateOptionsMenu()][3]` is called.

 Android ActionBarCompat-ListPopupMenu Sample
-==============================
+===================================
 
-This sample shows you how to use {@link android.support.v7.widget.PopupMenu PopupMenu}
-from ActionBarCompat to create a list, with each item having a dropdown menu.
+This sample shows how to display a pop up menu using PopupMenu from the v7 appcompat library.
+
+Introduction
+------------
+
+This sample displays a list of items and for each item, an icon can be clicked. When it is clicked, a pop up menu is shown, placed below the item, using the [PopupMenu][1] from the v7 appcompat support library.
+
+The sample uses [ListFragment][2] from the v4 support library to display the list. It shows how to instantiate and display the [PopupMenu][1], as well as how to use `setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener())` to process the user actions on the [PopupMenu][1].

 Android ActionBarCompat-ShareActionProvider Sample
-==============================
+===================================
 
 This sample shows you how a provide a context-sensitive ShareActionProvider with
 ActionBarCompat, backwards compatible to API v7.
 
+Introduction
+------------
+
+The sample contains a [`ViewPager`][1] which displays content of differing types: image and
+text. When a new item is selected in the ViewPager, the [`ShareActionProvider`][2] is updated with
+a share intent specific to that content.
+
+This Activity extends from [`ActionBarActivity`][3], which provides all of the function
+necessary to display a compatible Action Bar on devices running Android v2.1+.

 Android AdvancedImmersiveMode Sample
-==============================
+===================================
 
-
-\n"Immersive Mode", added in Android 4.4, improves the "hide full screen" and
-"hide nav bar" modes, by letting users swipe the bars in and out.This sample
+Immersive Mode, added in Android 4.4, improves the "hide full screen" and
+"hide nav bar" modes by letting users swipe the bars in and out.  This sample
 lets the user experiment with immersive mode by seeing how it interacts
 with some of the other UI flags related to full-screen apps.
 
+Introduction
+------------
+
+Android 4.4 (API Level 19) introduces a new `SYSTEM_UI_FLAG_IMMERSIVE`
+flag for [setSystemUiVisibility()][1] that lets your app go truly "full
+screen." This flag, when combined with the `SYSTEM_UI_FLAG_HIDE_NAVIGATION` and
+`SYSTEM_UI_FLAG_FULLSCREEN` flags, hides the navigation and status bars
+and lets your app capture all touch events on the screen.
+
+When immersive full-screen mode is enabled, your activity continues
+to receive all touch events. The user can reveal the system bars with
+an inward swipe along the region where the system bars normally
+appear.
+

+# How to become a contributor and submit your own code
+
+## Contributor License Agreements
+
+We'd love to accept your sample apps and patches! Before we can take them, we
+have to jump a couple of legal hurdles.
+
+Please fill out either the individual or corporate Contributor License Agreement (CLA).
+
+  * If you are an individual writing original source code and you're sure you
+    own the intellectual property, then you'll need to sign an [individual CLA]
+    (https://cla.developers.google.com).
+  * If you work for a company that wants to allow you to contribute your work,
+    then you'll need to sign a [corporate CLA]
+    (https://cla.developers.google.com).
+
+Follow either of the two links above to access the appropriate CLA and
+instructions for how to sign and return it. Once we receive it, we'll be able to
+accept your pull requests.
+
+## Contributing A Patch
+
+1. Submit an issue describing your proposed change to the repo in question.
+1. The repo owner will respond to your issue promptly.
+1. If your proposed change is accepted, and you haven't already done so, sign a
+   Contributor License Agreement (see details above).
+1. Fork the desired repo, develop and test your code changes.
+1. Ensure that your code adheres to the existing style in the sample to which
+   you are contributing. Refer to the
+   [Android Code Style Guide]
+   (https://source.android.com/source/code-style.html) for the
+   recommended coding standards for this organization.
+1. Ensure that your code has an appropriate set of unit tests which all pass.
+1. Submit a pull request.

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+

+Android AgendaData Sample
+===================================
+
+Sample demonstrating sync of calendar events to a wearable by the press of a button.
+
+Introduction
+------------
+
+Using the Wearable [DataApi][1] allows to transmit data such as event time,
+description, and background image.
+
+The sent [DataItems][2] can be deleted individually via an action on the event notifications,
+or all at once via a button on the companion.
+
+When deleted using the notification action, a ConfirmationActivity is used to indicate
+success or failure. The sample shows implementations for both the success as well failure case.

+Android AppRestrictionSchema Sample
+===================================
+
+A basic app showing how to allow a device administrator to restrict user
+activities using the Android Device Administration API. The app exports
+a custom policy that enables or disables a UI control. Device Administration
+applications are able to enforce a specific value for this policy, as
+directed by enterprise administrators.
+
+Introduction
+------------
+
+The [Android Device Administration API][1] allows enterprise administrators to
+enforce specific policies on a managed device. The system provides policies
+that control settings such as password complexity, screen lock, or camera
+availability. Developers can also augment this list with custom policies
+that control specific features within their applications. For example,
+a web browser could provide access to a whitelist of allowed domains.
+
+The list of policies exposed by an app must be specified using a file
+inside of the `res/xml` directory, using the `<restriction>` tag:
+
+```xml
+<restrictions xmlns:android="http://schemas.android.com/apk/res/android">
+
+    <restriction
+            android:defaultValue="false"
+            android:description="@string/description_can_say_hello"
+            android:key="can_say_hello"
+            android:restrictionType="bool"
+            android:title="@string/title_can_say_hello" />
+
+</restrictions>
+```
+
+In this sample, that file can be found at
+`Application/src/main/res/xml/app_restrictions.xml`. This file must be
+also be declared inside of `ApplicationManifest.xml` using a `<meta-data>`
+element:
+
+```xml
+<meta-data
+        android:name="android.content.APP_RESTRICTIONS"
+        android:resource="@xml/app_restrictions" />
+```
+
+At runtime, the current list of restrictions enforced by policy can be
+checked by calling [RestrictionsManager.getApplicationRestrictions()][2].

+Android AppUsageStatistics Sample
+===================================
+
+A basic app showing how to use App usage statistics API to let users collect statistics related
+to usage of the applications.
+
+Introduction
+------------
+
+The [App usage statistics][1] API allows app developers to collect statistics related to usage of
+the applications. This API provides more detailed usage information than the deprecated
+[getRecentTasks()][2] method.
+
+This example illustrates how to use the App usage statistics API by showing the applications sorted
+by the timestamp of the last time each app was used.
+
+To use this API, you must first declare the `android.permission.PACKAGE_USAGE_STATS` permission
+in your manifest. The user must also enable access for this app through
+`Settings > Security > Apps with usage access`.
+
+To collect the statistics of the app usage, you need to first get the instance of
+[UsageStatsManager][3] by the following code:
+
+```java
+mUsageStatsManager = (UsageStatsManager) getActivity()
+       .getSystemService(Context.USAGE_STATS_SERVICE);
+```
+
+Then you can retrieve the statistics of the app usage by the following method:
+
+```java
+Calendar cal = Calendar.getInstance();
+cal.add(Calendar.YEAR, -1);
+List<UsageStats> queryUsageStats = mUsageStatsManager
+        .queryUsageStats(UsageStatsManager.INTERVAL_DAILY, cal.getTimeInMillis(),
+                System.currentTimeMillis());
+```
+
+The first argument of the [queryUsageStats()][4] is used for the time interval by which the
+stats are aggregated. The second and the third arguments are used for specifying the beginning
+and the end of the range of the stats to include in the results.

 Android BasicAccessibility Sample
-==============================
+===================================
 
-This sample demonstrates how to create an accessible application, using a mix of different widgets demonstrating different ways of adding accessibility markup to a UI.
+This sample demonstrates how to create an accessible application, using a mix of different widgets
+demonstrating different ways of adding accessibility markup to a UI.
+
+Introduction
+------------
+
+This sample demonstrates how to create an accessible application, showing
+how to add accessibility to both framework and custom widgets.
+
+To run this sample as intended you will need to turn on TalkBack (or another text to speach system)
+on your Android device. Go to Settings > Accessibility > TalkBack to turn TalkBack on.
+
+When you run the sample with TalkBack mode on, TalkBack will read aloud the
+description of the in-focus widget.

 Android BasicAndroidKeyStore Sample
-==============================
+===================================
 
-Welcome to the <b>Basic Android Key Store</b> sample!
+An advanced sample displaying the creation and usage of data integrity mechanisms
 
-This sample demonstrates how to use the Android Key Store to safely create and store
-encryption keys that only your application can access.You can also sign data
-using those keys.
+Introduction
+------------
 
-To create a new KeyPair, click "Create".
+This sample demonstrates how to use the Android [KeyStore][1] to safely create and store
+encryption keys that only your application can access.
 
-To sign some data using a KeyPair, click "Sign".
+A [KeyPair][2] consisting of a [PrivateKey][3] and a [PublicKey][4] is being generated.
+The private key then is being used to sign and verify a String.
 
-To verify the data using the signature provided, click "Verify".
+Next to that appropriate exception handling for potential errors is being displayed.

 Android BasicContactables Sample
-==============================
+===================================
 
-This sample demonstrates how to use the Contactables table to search for contacts.
+This sample shows how to search for contacts, displaying a SearchView in the Action Bar for user input and implementing a query Cursor with CommonDataKinds.Contactables.
 
-Query strings sent to the Contactables table will match both contact names and phone numbers,
-reducing the number of queries your application needs to use when searching the contacts database!
+Introduction
+------------
+
+This sample displays a [SearchView][1] in the Action Bar when the search icon is clicked. It then implements the [LoaderManager.LoaderCallbacks][2] interface to query the contacts table, using a [CursorLoader][3].
+
+For details on how to implement the [SearchView][1], refer to the training guide [Setting up the search interface][4].
+
+For details on how to implement the [LoaderManager.LoaderCallbacks][2] interface, refer to the [Using the LoaderManager Callbacks][5] guide.
+
+For details on how to query the contacts provider, refer to the [Contacts Provider Access][6] guide.

 Android BasicGestureDetect Sample
-==============================
+===================================
 
-Welcome to Basic Gesture Detect!
-In order to try this sample out, try dragging or tapping this text to see what happens!
+This sample detects gestures on a view and logs them. In order to try this
+sample out, try dragging or tapping the text.
+
+Introduction
+------------
+
+In this sample, the gestures are detected using a custom gesture listener that extends
+[SimpleOnGestureListener][1] and writes the detected [MotionEvent][2] into the log.
+
+In this example, the steps followed to set up the gesture detector are:
+1. Create the GestureListener that includes all your callbacks.
+2. Create the GestureDetector ([SimpleOnGestureListener][1]) that will take the listener as an argument.
+3. For the view where the gestures will occur, create an [onTouchListener][3]
+that sends all motion events to the gesture detector.
+

+
+Introduction
+------------
+
+'Immersive Mode' is a new UI mode which improves 'hide full screen' and 'hide nav bar' 
+modes, by letting users swipe the bars in and out.
+
+This sample demonstrates how to enable and disable immersive mode programmatically.
+
+Immersive mode was introduced in Android 4.4 (Api Level 19). It is toggled using the 
+SYSTEM_UI_FLAG_IMMERSIVE system ui flag. When combined with the SYSTEM_UI_FLAG_HIDE_NAVIGATION and SYSTEM_UI_FLAG_FULLSCREEN  flags, hides the navigation and status bars and lets your app capture all touch events on the screen.

 Android BasicManagedProfile Sample
-==============================
+===================================
 
-This sample demonstrates how to create a managed profile. You can also learn how to enable or
-disable other apps and how to set restrictions to them. Intents can be configured to be forwarded
-between primary account and managed profile. Finally, you can wipe all the data associated with the
-profile. Note that there can only be one managed profile on a device. 
+This sample demonstrates basic functionalities of Managed Profile API
+introduced in Android 5.0 Lollipop. You can set up this app as a
+profile owner, and use this app to enable/disable apps in the newly
+created managed profile. You can also set restrictions to some apps,
+enable/disable Intent forwarding between profiles, and wipe out all
+the data associated with the profile.
+
+Introduction
+------------
+
+As of Android 5.0, DevicePolicyManager introduces new features to
+support managed profile.
+
+To set up this app as a profile owner, you need to encrypt your device
+(you are prompted to do if you haven't). This doesn't wipe out the
+device, but be aware that you can set up only one managed profile at a
+time.
+
+[isProfileOwnerApp][1] can be used to determine if a particular
+package is registered as the profile owner for the current user. You
+can initiate the provisioning flow of a managed profile with Intent of
+[ACTION_PROVISION_MANAGED_PROFILE][2].
+
+You have to implement a class extending [DeviceAdminReceiver][3] to
+receive the result of the provisioning flow. Use
+[setProfileEnabled][4] to enable the newly created profile, and your
+app is now set up as a profile owner.

 Android BasicMediaDecoder Sample
-==============================
+===================================
 
-This activity uses a TextureView to render the frames of a video decoded using the
-MediaCodec API.
+This sample shows how to use the MediaCoder to decode a video,
+use a TimeAnimator to sync the rendering commands with the system
+display frame rendering and finally render it to a TextureView.
+
+Introduction
+------------
+
+[MediaCodec][1] was introduced in API 16, and can be used for low level (decoding/encoding) operations.
+In the same API was also introduced [TimeAnimator][2], which can be used to synchronise animation frames.
+Finally, [MediaExtractor][3] provides a simple way to extract demuxed media data from a data source.
+
+The main steps are described below:
+
+1. Create a layout with a [TextureView][4] for your activity.
+2. Initialise a MediaExtractor instance with `new MediaExtractor()` and a TimeAnimator instance with
+`new TimeAnimator()`.
+3. To start video playback, call `setDataSource(this, videoUri, null)` on your MediaExtractor instance,
+where `videoUri` is the URI of your video source.
+4. On your MediaExtractor instance, call `getTrackCount()` to know how many tracks you have in your streams.
+They may not all be video tracks. Deselect all tracks by calling `unselectTrack(i)` where `i` is
+the index of the track.
+5. Get the mime type of a track by calling `getTrackFormat(i).getString(MediaFormat.KEY_MIME)`
+on your MediaExtractor instance, where `i` is the index of your selected track.
+If the mime type contains "video/", then this is a video track so you can select it, using `selectTrack(i)`
+on your MediaExtractor instance.
+6. Create a MediaCodec instance by calling `MediaCodec.createDecoderByType(mimeType)`.
+7. Configure your MediaCodec instance with `configure(trackFormat, textureView, null,  0)`,
+where `trackFormat` is obtained by calling `getTrackFormat(i)` on your MediaExtractor instance.
+8. Set a TimeListener on your TimeAnimation instance, and override its `onTimeUpdate(final TimeAnimator animation,
+final long totalTime, final long deltaTime)` method.
+9. In `onTimeUpdate`, check if the media track has reached the end of stream, using `getSampleFlags()`
+on  your MediaExtractor instance and looking for `MediaCodec.BUFFER_FLAG_END_OF_STREAM` flag.
+10. Still in `onTimeUpdate`, assuming this isn't the end of the sample, write the media sample to your
+MediaDecoder instance, using `queueInputBuffer(index, 0, size, presentationTimeUs, flags)` method.
+You will need to set up your buffers, refer to [MediaCodec][1] documentation for details.
+11. After writing the media sample, you need to advance the sample, calling `advance()` on your
+TimeExtractor instance (this is a blocking operation and should be done outside the main thread).
+12. Finally, you can release and render the media sample by calling
+`dequeueOutputBuffer(info, timeout)` and `releaseOutputBuffer(i, true)`, refer to [MediaCodec][1]
+documentation for details.
+13. In `onPause()` or if you have reached the end of the stream, call `end()` on your TimeAnimation instance,
+then call `stop()` and `release()` on your MediaCodec instance, and finally, call `release()` on your
+MediaExtractor instance.

 Android BasicMultitouch Sample

+===================================
 
-This samples demonstrates the use of MotionEvent properties to keep track of individual touches
-across multiple touch events.
+Sample demonstrates the use of [MotionEvent][1] properties to keep track of
+individual touches across multiple touch events.
 
-Touch the screen with multiple fingers to show that the pointer id

+
+Introduction
+------------
+
+This is an example of keeping track of individual touches across multiple
+[MotionEvent][1]s.
+
+This sample uses a custom View (`TouchDisplayView`) that responds to
+touch events and draws a colored circle for each touch point. The view holds
+data related to a touch pointer, including its current position, pressure,
+and its past touch history.
+
+The View draws graphics based on data associated with each touch event to a
+canvas. A large circle indicates the current position of a touch, while smaller
+trailing circles represent previous positions for that touch.
+The size of the large circle is scaled depending on the pressure of the user's
+touch.

 Android BasicNotifications Sample
-==============================
+===================================
 
-This sample demonstrates how to display events in the system\'s notification bar. The
+A basic app showing how to display events in the system's notification bar using
+the NotificationCompat API.
 NotificationCompat API is used for compatibility with older devices, running Android
-2.2 (Froyo) or newer.
+1.6 (Donut) (API level 4) or newer.
+
+Introduction
+------------
+
+The [Notification API][1] allows the app developers to display a message outside
+of your application's normal UI.
+
+The class [Notification][2] was added in the Android 3.0 (API level 11), but this
+sample refers to the [NotificationCompat][3] class (part of the [support library][4]),
+ which offers the same functionality for Android 1.6 (API level 4) or newer.
+
+A Notificaiton can be created using Notification.Builder object.
+At bare minimum, a Builder object must include the following:
+- A small icon, set by [setSmallIcon()][5]
+- A title, set by [setContentTitle()][6]
+- Detail text, set by [setContentText()][7]
+
+in the code snippet, it looks like following.
+```java
+NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
+builder.setSmallIcon(R.drawable.ic_stat_notification);
+builder.setContentTitle("BasicNotifications Sample");
+builder.setContentText("Time to learn about notifications!");
+```
+
+To issue the notification, call notify() method in the [NotificationManager][8].
+The code snippet will immediately display the notification icon in the
+notification bar.
+
+```java
+NotificationManager notificationManager = (NotificationManager) getSystemService(
+        NOTIFICATION_SERVICE);
+notificationManager.notify(NOTIFICATION_ID, builder.build());
+```

 Android BasicRenderScript Sample
-==============================
+===================================
 
-BasicRenderScript sample demonstrates basic steps how to use renderScript.
-			In the sample, it performs graphical filter operation on a image with renderScript.
+This sample demonstrates using RenderScript to perform basic image manipulation. Specifically, it allows users
+to dynamically adjust the saturation for an image using a slider. A custom RenderScript kernel performs the saturation
+adjustment, running the computation on the device's GPU or other compute hardware as deemed appropriate by the system.
+
+Introduction
+------------
+
+[RenderScript][1] is a framework for running computationally intensive tasks at high performance on Android. RenderScript is
+primarily oriented for use with data-parallel computation, although serial computationally intensive workloads can
+benefit as well.
+
+The RenderScript runtime will parallelize work across all processors available on a device, such as multi-core CPUs,
+GPUs, or DSPs, allowing you to focus on expressing algorithms rather than scheduling work or load balancing.
+RenderScript is especially useful for applications performing image processing, computational photography, or computer
+vision.
+
+This sample demonstrates the fundamentals of writing a RenderScript compute kernel, and using it to perform basic image
+manipulation. In this case, each pixel is transformed based on a liner interpolation between its original
+RGB value and it's luminance (black-and-white) value, weighted based on the user's specified saturation target.

 Android BasicSyncAdapter Sample
-==============================
+===================================
 
-This sample demonstrates using SyncAdapter to fetch background data for an app that
-doesn\'t require a user-visible account type or 2-way synchronization.
+This sample demonstrates using SyncAdapter to fetch background
+data for an app. It covers the creation of the required Service
+that the OS uses to initiate the background data sync as well as
+scheduling syncs with background data.
 
+Introduction
+------------
 
-This sample periodically downloads the feed from the Android Developer Blog and
-caches the data in a content provider. At runtime, the cached feed data is displayed
-inside a ListView.
+This sample demonstrates using SyncAdapter to fetch background data
+for an app. SyncAdapters can be used to execute your data transfer
+code at configurable intervals, while efficiently using battery and
+other system resources.
+
+This sample implements all the required elements of a sync adapter.
+- Creates a sync adapter class.
+- Creates a bound Service which the OS uses to initiate a sync.
+- Defines the sync adapter properties in an XML resource file.
+- Declares the bound Service in the app manifest.
+
+For more on SyncAdapters refer to [Transferring Data Using Sync Adapters][1]
+

 Android BasicTransition Sample
-==============================
+===================================
 
-This sample demonstrates the basic use of the transition framework introduced in KitKat.
-	Select each of the RadioButtons to switch between the Scenes.
+A basic app showing how to use the Transition framework introduced in
+KitKat. The app shows radioboxes to select between different Scenes,
+and uses various ways to transition between them.
+
+Introduction
+------------
+
+A Scene is an encapsulation of the state of a view hierarchy,
+including the views in that hierarchy and the various values
+(layout-related and otherwise) that those views have. A scene can be
+defined by a layout hierarchy directly or by code which sets up the
+scene dynamically as it is entered.
+
+A Transition is a mechanism to automatically animate changes that
+occur when a new scene is entered. Some transition capabilities are
+automatic. That is, entering a scene may cause animations to run which
+fade out views that go away, changeBounds and resize existing views
+that change, and fade in views that become visible. There are
+additional transitions that can animate other attributes, such as
+color changes, and which can optionally be specified to take place
+during particular scene changes. Finally, developers can define their
+own Transition subclasses which monitor particular property changes
+and which run custom animations when those properties change values.
+
+TransitionManager is used to specify custom transitions for particular
+scene changes, and to cause scene changes with specific transitions to
+take place.

+Android BluetoothChat Sample
+===================================
+
+This sample shows how to implement two-way text chat over Bluetooth between two Android devices, using
+all the fundamental Bluetooth API capabilities.
+
+Introduction
+------------
+
+This sample should be run on two Android devices at the same time, to establish a two-way chat over
+Bluetooth between the devices. Select "Made discoverable" in overflow menu on one device and click
+on the Bluetooth icon on the other one, to find the device and establish the connection.
+
+The sample demonstrates the following, using the [Bluetooth API][1]:
+
+1. [Setting up][2] Bluetooth
+2. [Scanning][3] for other Bluetooth devices
+3. [Querying][4] the local Bluetooth adapter for paired Bluetooth devices
+4. [Establishing RFCOMM][5] channels/sockets
+5. [Connecting][6] to a remote device
+6. [Transfering][7] data over Bluetooth

 Android BluetoothLeGatt Sample
-==============================
+===================================
 
 This sample demonstrates how to use the Bluetooth LE Generic Attribute Profile (GATT)
 to transmit arbitrary data between devices.
 
+Introduction
+------------
+
+This sample shows a list of available Bluetooth LE devices and provides
+an interface to connect, display data and display GATT services and
+characteristics supported by the devices.
+
+It creates a [Service][1] for managing connection and data communication with a GATT server
+hosted on a given Bluetooth LE device.
+
+The Activities communicate with the Service, which in turn interacts with the [Bluetooth LE API][2].

 Android BorderlessButtons Sample
-==============================
+===================================
 
-This sample demonstrates the use of borderless buttons, bottom button bars
-(OK and Cancel) and dividers to establish visual structure.
+This sample demonstrates the borderless button styling from the Holo visual language.
+Styling is applied in the XML resource layout definitions, referecing the styling attributes
+from the Holo theme.
+
+Introduction
+------------
+
+This sample shows how to style widgets in an Activity using [borderless elements][1].
+This includes a ListView with custom rows and buttons, using dividing lines to create
+visual separatation.
+
+Style definitions are provided by the Holo theme, which includes references to the 
+'?android:buttonBarButtonStyle' for buttons and references to the appropriate divider 
+attribute and style 'android:dividerVertical'.
+
+Styles are directly applied to widgets in their XML layout definitions.

 Android Camera2Basic Sample
-==============================
+===================================
 
-This sample demonstrates the basic use of Camera2 API. Check the source code to see how you can
-display camera preview and take pictures.
+This sample demonstrates how to use basic functionalities of Camera2
+API. You can learn how to iterate through characteristics of all the
+cameras attached to the device, display a camera preview, and take
+pictures.
+
+Introduction
+------------
+
+The [Camera2 API][1] provides an interface to individual camera
+devices connected to an Android device. It replaces the deprecated
+Camera class.
+
+Use [getCameraIdList][2] to get a list of all the available
+cameras. You can then use [getCameraCharacteristics][3] and find the
+best camera that suits your need (front/rear facing, resolution etc).
+
+Create an instance of [CameraDevice.StateCallback][4] and open a
+camera. It is ready to start camera preview when the camera is opened.
+
+This sample uses TextureView to show the camera preview. Create a
+[CameraCaptureSession][5] and set a repeating [CaptureRequest][6] to it.
+
+Still image capture takes several steps. First, you need to lock the
+focus of the camera by updating the CaptureRequest for the camera
+preview. Then, in a similar way, you need to run a precapture
+sequence. After that, it is ready to capture a picture. Create a new
+CaptureRequest and call [capture][7]. Don't forget to unlock the focus
+when you are done.

 Android Camera2Video Sample
-==============================
+===================================
 
-This sample demonstrates how to record video using Camera2 API.
+This sample shows how to record video using the new Camera2 API in Android Lollipop.
+
+Introduction
+------------
+
+Android Lollipop introduced a new camera API, called camera2. This sample uses [CameraDevice][1]
+and [CameraCaptureSession][2] to record video. It also uses a custom [TextureView][3] to render the output.
+
+The main steps are:
+
+1. Create a custom TextureView class and add it to the layout. The purpose of the custom TextureView is
+to be able to draw itself according to an aspect ratio, which is set via a public method. Additionally,
+the `onMeasure(int widthMeasureSpec, int heightMeasureSpec)` method is overridden, using the aspect ratio.
+2. Implement a `TextureView.SurfaceTextureListener` on your TextureView, and override its
+`onSurfaceTextureSizeChanged(SurfaceTexture surfaceTexture, int width, int height)` method to calculate
+the matrix to apply to the TextureView so the camera output fits. Use the method `setTransform(matrix)` on
+the TextureView.
+3. Implement a [`CameraDevice.StateCallback`][4] to receive events about changes of the state of the
+camera device. Override its methods to set your CameraDevice instance, start the preview, and stop
+and release the camera.
+4. When starting the preview, set up the MediaRecorder to accept video format.
+5. Then, set up a [`CaptureRequest.Builder`][5] using `createCaptureRequest(CameraDevice.TEMPLATE_RECORD)`
+on your CameraDevice instance.
+6. Then, implement a [`CameraCaptureSession.StateCallback`][6], using the method
+`createCaptureSession(surfaces, new CameraCaptureSession.StateCallback(){})` on your CameraDevice instance,
+where `surfaces` is a list consisting of the surface view of your TextureView and the surface of
+your MediaRecorder instance.
+7. Use `start()` and `stop()` methods on your MediaRecorder instance to actually start and stop the recording.
+8. Lastly, set up and clean up your camera device in `onResume()` and `onPause()`.

 Android ClippingBasic Sample
-==============================
+===================================
 
-Basic sample to demonstrate clipping on a View.
+A basic app showing how to clip on a View using [ViewOutlineProvider][1] interface,
+by which a View builds its outline, used for shadowing and clipping.
+
+Introduction
+------------
+
+The [ViewOutlineProvider][1] interface offers you a method to populate the outline of a View.
+You need to implement a getOutline(android.view.View, android.graphics.Outline)
+method to clip a View in a specific shape.
+
+This example clips the outline of a View as a rounded rectangle by defining a class that
+ implements ViewOutlineProvider by following code:
+
+```java
+private class ClipOutlineProvider extends ViewOutlineProvider {
+    @Override
+    public void getOutline(View view, Outline outline) {
+        final int margin = Math.min(view.getWidth(), view.getHeight()) / 10;
+        outline.setRoundRect(margin, margin, view.getWidth() - margin,
+                view.getHeight() - margin, margin / 2);
+    }
+}
+```
+
+To clip a View by the defined outline, setting a OutlineProvider to a View
+to be clipped is needed like following:
+
+```java
+final View clippedView = view.findViewById(R.id.frame);
+clippedView.setOutlineProvider(mOutlineProvider);
+```
+
+You can toggle if the View is clipped by calling [setClipToOutline(boolean)][2]
+like following code:
+
+```java
+clippedView.setClipToOutline(true); // Setting false disable clipping
+```
+

 Android CustomChoiceList Sample
-==============================
+===================================
 
-This sample demonstrates how to create custom checkable layouts, for use with ListView\'s choiceMode
+This sample demonstrates how to create custom checkable layouts, for use with ListView's choiceMode
 attribute.
 
+Introduction
+------------
+
+This sample demonstrates how to create custom single- or multi-choice [ListView][1] UIs on Android.
+
+When a ListView has a `android:choiceMode` attribute set, it will allow users to "choose" one or more items. For
+exmaple, refer to `res/layout/sample_main.xml` in this project:
+
+```xml
+<ListView android:id="@android:id/list"
+    android:layout_width="match_parent"
+    android:layout_height="0dp"
+    android:layout_weight="1"
+    android:paddingLeft="@dimen/page_margin"
+    android:paddingRight="@dimen/page_margin"
+    android:scrollbarStyle="outsideOverlay"
+    android:choiceMode="multipleChoice" />
+```
+
+The framework provides these default list item layouts that show standard radio buttons or check boxes next to a single
+line of text:
+
+- android.R.layout.simple_list_item_single_choice
+- android.R.layout.simple_list_item_multiple_choice.
+
+In some cases, you may want to customize this layout. When doing so, the root view must implement the Checkable
+interface. For an example, see this sample's `CheckableLinearLayout` class.
+
+Lastly, remember to use padding on your ListViews to adhere to the standard metrics described in the Android Design
+guidelines. When doing so, you should set the `android:scrollbarStyle` attribute such that the scrollbar doesn't inset.
+

 Android CustomTransition Sample
-==============================
+===================================
 
-This sample demonstrates how to create and use a custom Transition.
+This sample shows how to implement a custom Transition extending the
+standard Transition class.
+
+Introduction
+------------
+
+In order to create a custom Transition, you first need to override
+[captureStartValues][1] and [captureEndValues][2]. In those method, you have to
+extract all the relevant properties from a View. These methods are called for
+each of the Views in the hierarchy.
+
+Then, you need to override [createAnimator][3] and create an Animator based on
+the property values you extracted. This method will also be called for each of
+the Views in the hierarchy. If you want to skip some Views, simply return null.
+
+The instantiated custom Transition can be applied by passing it as the second
+parameter of [TransitionManager.go][4].
+
+```java
+TransitionManager.go(mScenes[mCurrentScene], mTransition);
+```

+# How to become a contributor and submit your own code
+
+## Contributor License Agreements
+
+We'd love to accept your sample apps and patches! Before we can take them, we
+have to jump a couple of legal hurdles.
+
+Please fill out either the individual or corporate Contributor License Agreement (CLA).
+
+  * If you are an individual writing original source code and you're sure you
+    own the intellectual property, then you'll need to sign an [individual CLA]
+    (https://cla.developers.google.com).
+  * If you work for a company that wants to allow you to contribute your work,
+    then you'll need to sign a [corporate CLA]
+    (https://cla.developers.google.com).
+
+Follow either of the two links above to access the appropriate CLA and
+instructions for how to sign and return it. Once we receive it, we'll be able to
+accept your pull requests.
+
+## Contributing A Patch
+
+1. Submit an issue describing your proposed change to the repo in question.
+1. The repo owner will respond to your issue promptly.
+1. If your proposed change is accepted, and you haven't already done so, sign a
+   Contributor License Agreement (see details above).
+1. Fork the desired repo, develop and test your code changes.
+1. Ensure that your code adheres to the existing style in the sample to which
+   you are contributing. Refer to the
+   [Android Code Style Guide]
+   (https://source.android.com/source/code-style.html) for the
+   recommended coding standards for this organization.
+1. Ensure that your code has an appropriate set of unit tests which all pass.
+1. Submit a pull request.

+
+      "Source" form shall mean the preferred form for making modifications,

+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent

+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed

+Android DataLayer Sample
+===================================
+
+This sample demonstrates how to work with a WearableListenerService,
+to produce and consume DataEvents and effectively work with the DataLayer.
+
+Introduction
+------------
+
+This sample demonstrates how to make a handheld and an Android Wear device communicate
+using the [DataApi][2].
+It does this by sending a picture between connected devices.
+
+An Activity is being used for both the connected devices which implement their parts of
+the required interfaces.
+
+It showcases how to use an [WearableListenerService][1] to consume DataEvents
+as well as implementations for various required listeners when using the [DataApi][2],
+[MessageApi][3] and [NodeApi][4].

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+

+Android DirectorySelection Sample
+===================================
+
+A basic app showing how to use Directory Selection API to let users
+select an entire directory subtree, which extends the Storage Access Framework
+introduced in Android 4.4 (API level 19).
+
+Introduction
+------------
+
+The [Directory Selection][1] API, which was introduced in Android 5.0 (API level 21)
+extends the [Storage Access Framework][2] to let users select an entire directory subtree,
+giving apps read/write access to all contained documents without requiring user
+confirmation for each item.
+
+To select a directory subtree, build and send an [OPEN_DOCUMENT_TREE intent][3] like in the
+following code:
+
+```java
+Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT_TREE);
+startActivityForResult(intent, REQUEST_CODE_OPEN_DIRECTORY);
+```
+
+The system displays all [DocumentsProvider][4] instances that support subtree selection,
+ letting the user browse and select a directory.
+
+The returned URI represents access to the selected subtree. You can then use
+[buildChildDocumentsUriUsingTree()][5] to access to the child documents and
+[buildDocumentUriUsingTree()][6] to access to the selected directory itself along with [query()][7]
+to explore the subtree.
+
+This example explores the child documents and the selected document by following code:
+
+```java
+@Override
+public void onActivityResult(int requestCode, int resultCode, Intent data) {
+    super.onActivityResult(requestCode, resultCode, data);
+    if (requestCode == REQUEST_CODE_OPEN_DIRECTORY && resultCode == Activity.RESULT_OK) {
+        updateDirectoryEntries(data.getData());
+    }
+}
+
+void updateDirectoryEntries(Uri uri) {
+    ContentResolver contentResolver = getActivity().getContentResolver();
+    Uri docUri = DocumentsContract.buildDocumentUriUsingTree(uri,
+            DocumentsContract.getTreeDocumentId(uri));
+    Uri childrenUri = DocumentsContract.buildChildDocumentsUriUsingTree(uri,
+            DocumentsContract.getTreeDocumentId(uri));
+
+    Cursor docCursor = contentResolver.query(docUri, new String[]{
+            Document.COLUMN_DISPLAY_NAME, Document.COLUMN_MIME_TYPE}, null, null, null);
+    try {
+        while (docCursor.moveToNext()) {
+            Log.d(TAG, "found doc =" + docCursor.getString(0) + ", mime=" + docCursor
+                    .getString(1));
+            mCurrentDirectoryUri = uri;
+            mCurrentDirectoryTextView.setText(docCursor.getString(0));
+            mCreateDirectoryButton.setEnabled(true);
+        }
+    } finally {
+        closeQuietly(docCursor);
+    }
+
+    Cursor childCursor = contentResolver.query(childrenUri, new String[]{
+            Document.COLUMN_DISPLAY_NAME, Document.COLUMN_MIME_TYPE}, null, null, null);
+    try {
+        List<DirectoryEntry> directoryEntries = new ArrayList<>();
+        while (childCursor.moveToNext()) {
+            Log.d(TAG, "found child=" + childCursor.getString(0) + ", mime=" + childCursor
+                    .getString(1));
+            DirectoryEntry entry = new DirectoryEntry();
+            entry.fileName = childCursor.getString(0);
+            entry.mimeType = childCursor.getString(1);
+            directoryEntries.add(entry);
+        }
+        mAdapter.setDirectoryEntries(directoryEntries);
+        mAdapter.notifyDataSetChanged();
+    } finally {
+        closeQuietly(childCursor);
+    }
+}
+```
+
+Also, the new [createDocument()][8] method lets you create new documents or directories
+anywhere under the subtree.
+
+This example creates a new directory by following code:
+
+```java
+ContentResolver contentResolver = getActivity().getContentResolver();
+Uri docUri = DocumentsContract.buildDocumentUriUsingTree(uri,
+        DocumentsContract.getTreeDocumentId(uri));
+Uri directoryUri = DocumentsContract
+        .createDocument(contentResolver, docUri, Document.MIME_TYPE_DIR, directoryName);
+```

+Android DocumentCentricRecents Sample
+===================================
+
+Sample demonstrating the basic usage of the new 'Document Centric Apps' API.
+It let's you create new documents in the system overview menu and persists its
+state through reboots.
+
+Introduction
+------------
+
+This sample shows the basic usage of the new Document-Centric Apps API. The new
+API modifies the meaning of the Intent#FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET flag, which is
+now deprecated. In versions before L it serves to define a boundary between the main task and a
+subtask. The subtask holds a different thumbnail and all activities in it are finished when the
+task is reset. In L this flag causes a full break with the task that launched it. As such it has
+been renamed to Intent#FLAG_ACTIVITY_NEW_DOCUMENT.
+
+This sample mainly uses Intent flags in code. But Activities can also specify in their manifests
+that they shall always be launched into a new task in the above manner using the new activity
+attribute documentLaunchMode which may take on one of three values, “intoExisting” equivalent to
+NEW_DOCUMENT, “always” equivalent to NEW_DOCUMENT | MULTIPLE_TASK, “none” the default, and
+“never” which will negate the effect of any attempt to launch the activity with NEW_DOCUMENT.

 Android DoneBar Sample
-==============================
+===================================
 
-This sample demonstrates two alternative presentations of the
-action bar that are well-suited for simple data entry scenarios.
+This sample shows how to create a custom view in the ActionBar to show a done button, using
+2 alternative layouts. This is well suited for simple data entry activities, where the only
+options for the user are to cancel or confirm the data changes.
 
-In this presentation, a done bar replaces the action
-bar entirely, providing two direct actions to persist or dismiss changes. This is
-suitable for cases where no additional view details or actions are needed in the
-action bar.
+Introduction
+------------
+
+API 11 introduced the [ActionBar][1] as a navigational UI element. In most cases, a custom view isn't required
+or even recommended, as using a menu xml file is all that is needed to add action icons to it. However, it is
+possible to use a custom view and it is useful in some cases.
+
+This sample contains two activities with custom views in their action bar, each with a "done" button. These are
+designed to be used with simple data entry screen where the only options for the user are to cancel or confirm
+the changes.
+
+1. Create a layout for the [ActionBar][2].
+2. In the activity, before setting the content view, inflate the view using the LayoutInflater.
+3. Use `getActionBar()` to get the ActionBar, and set the display options with `ActionBar.DISPLAY_SHOW_CUSTOM`.
+4. Set the custom view by calling `setCustomView(customActionBarView, new ActionBar.LayoutParams(
+ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.MATCH_PARENT))` on the ActionBar.
+5. You can now set the content view of the Activity.

 Sample that shows applying tinting and color filters to Drawables both programmatically
 and as Drawable resources in XML.
 
-Introduction
-------------
-
 Tinting is set on a nine-patch drawable through the "tint" and "tintMode" parameters.
 A color state list is referenced as the tint color, which defines colors for different
 states of a View (for example disabled/enabled, focused, pressed or selected).

 Android ElevationBasic Sample
-==============================
+===================================
 
-This sample demonstrates two alternative ways to move a view in the z-axis. The
-first view has a fixed elevation using XML and the second one is raised when the user
-taps on it, using setTranslationZ().
+This sample demonstrates ways to move a view in the z-axis using
+`setTranslationZ()`. This method was introduced in API Level 21 ('Lollipop').
+
+Introduction
+------------
+
+This sample uses two shapes, a circle and a square, and it demonstrates two
+alternative ways to move a view in the z-axis. The first shape, the circle,
+has a fixed elevation, which is defined in XML. The second view, the square,
+changes its elevation using [setTranslationZ()][1] when a user touches it:
+
+    shape2.setOnTouchListener(new View.OnTouchListener() {
+        @Override
+        public boolean onTouch(View view, MotionEvent motionEvent) {
+            int action = motionEvent.getActionMasked();
+            /* Raise view on ACTION_DOWN and lower it on ACTION_UP. */
+            switch (action) {
+                case MotionEvent.ACTION_DOWN:
+                    Log.d(TAG, "ACTION_DOWN on view.");
+                    view.setTranslationZ(120);
+                    break;
+                case MotionEvent.ACTION_UP:
+                    Log.d(TAG, "ACTION_UP on view.");
+                    view.setTranslationZ(0);
+                    break;
+                default:
+                    return false;
+            }
+            return true;
+        }
+    });
+
+The elevation reverts back once the touch is removed.

 Android ElevationDrag Sample
-==============================
+===================================
 
 This sample demonstrates a drag and drop action on different shapes. Elevation and
 z-translation are used to render the shadows and the views are clipped using different
 Outlines.
 
+Introduction
+------------
+
+This sample demonstrates a drag and drop action on different shapes. Elevation and
+z-translation are used to render the shadows and the views are clipped using different
+Outlines.
+
+Elevation is considered the static or initial position of a view on the z axis, while
+translationZ exists for transient states, like animations.
+
+`Z = elevation + translationZ`
+
+See [Assign Elevation to Your Views][1] for more info.

+# How to become a contributor and submit your own code
+
+## Contributor License Agreements
+
+We'd love to accept your sample apps and patches! Before we can take them, we
+have to jump a couple of legal hurdles.
+
+Please fill out either the individual or corporate Contributor License Agreement (CLA).
+
+  * If you are an individual writing original source code and you're sure you
+    own the intellectual property, then you'll need to sign an [individual CLA]
+    (https://cla.developers.google.com).
+  * If you work for a company that wants to allow you to contribute your work,
+    then you'll need to sign a [corporate CLA]
+    (https://cla.developers.google.com).
+
+Follow either of the two links above to access the appropriate CLA and
+instructions for how to sign and return it. Once we receive it, we'll be able to
+accept your pull requests.
+
+## Contributing A Patch
+
+1. Submit an issue describing your proposed change to the repo in question.
+1. The repo owner will respond to your issue promptly.
+1. If your proposed change is accepted, and you haven't already done so, sign a
+   Contributor License Agreement (see details above).
+1. Fork the desired repo, develop and test your code changes.
+1. Ensure that your code adheres to the existing style in the sample to which
+   you are contributing. Refer to the
+   [Android Code Style Guide]
+   (https://source.android.com/source/code-style.html) for the
+   recommended coding standards for this organization.

+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"

+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and

+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and

+Android ElizaChat Sample
+===================================
+
+A basic sample showing how to add extensions to notifications on wearable using
+[NotificationCompat.WearableExtender][1] API by providing a chat experience.
+
+Introduction
+------------
+
+[NotificationCompat.WearableExtender][1] API offers you a functionality to
+ add wearable extensions to notifications like [Add the Voice Input as a Notification Action][2].
+
+This example also adds the wearable notifications as a voice input by the following code:
+
+```java
+NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
+        .setContentTitle(getString(R.string.eliza))
+        .setContentText(mLastResponse)
+        .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.drawable.bg_eliza))
+        .setSmallIcon(R.drawable.bg_eliza)
+        .setPriority(NotificationCompat.PRIORITY_MIN);
+
+Intent intent = new Intent(ACTION_RESPONSE);
+PendingIntent pendingIntent = PendingIntent.getService(this, 0, intent,
+        PendingIntent.FLAG_ONE_SHOT | PendingIntent.FLAG_CANCEL_CURRENT);
+Notification notification = builder
+        .extend(new NotificationCompat.WearableExtender()
+                .addAction(new NotificationCompat.Action.Builder(
+                        R.drawable.ic_full_reply, getString(R.string.reply), pendingIntent)
+                        .addRemoteInput(new RemoteInput.Builder(EXTRA_REPLY)
+                                .setLabel(getString(R.string.reply))
+                                .build())
+                        .build()))
+        .build();
+NotificationManagerCompat.from(this).notify(0, notification);
+```
+
+When you issue this notification, users can swipe to the left to see the "Reply" action button.
+
+When you receive the response, you can do it by the following code:
+
+```java
+@Override
+public int onStartCommand(Intent intent, int flags, int startId) {
+    if (null == intent || null == intent.getAction()) {
+        return Service.START_STICKY;
+    }
+    String action = intent.getAction();
+    if (action.equals(ACTION_RESPONSE)) {
+        Bundle remoteInputResults = RemoteInput.getResultsFromIntent(intent);
+        CharSequence replyMessage = "";
+        if (remoteInputResults != null) {
+            replyMessage = remoteInputResults.getCharSequence(EXTRA_REPLY);
+        }
+        processIncoming(replyMessage.toString());
+    } else if (action.equals(MainActivity.ACTION_GET_CONVERSATION)) {
+        broadcastMessage(mCompleteConversation.toString());
+    }
+    return Service.START_STICKY;
+}
+```

+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed

+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify

+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade

+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.

+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing

+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+Android EmbeddedApp Sample
+===================================
+
+This simple app demonstrates how to embed a wearable app into a phone app.
+
+Introduction
+------------
+
+Wearable apps can be installed directly onto Android Wear devices during development, using either a direct ADB
+connection or ADB-over-Bluetooth. However, when releasing your app to end users, you must package your
+wearable APK inside of a traditional APK for distribution via a paired phone.
+
+When end users install this APK onto their phone, the wearable APK will be automatically detected, extracted, and pushed
+to their any paired wearable devices.
+
+This sample demonstrates how to properly package a wearable app for release in this manner. The wearable app is inside
+the `Wearable` directory, and the phone app (which will be used as a container for distribution) is the `Application`
+directory. There is nothing special about these apps, other than the `wearApp` dependency in the (host) phone app's
+`build.gradle` file:
+
+```groovy
+dependencies {
+    compile 'com.google.android.gms:play-services-wearable:6.5.+'
+    wearApp project(':Wearable')
+}
+```
+
+This dependency will automatically package the wearable APK during a **release build** (e.g. using the "Build > Generate
+Signed APK..." command in Android Studio). Note that this packaging is **not** performed for debug builds for
+performance reasons. During development, your wearable and phone apps must still be pushed individually to their
+respective devices using an ADB connection.

+      communication on electronic mailing lists, source code control systems,

+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and

+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+# How to become a contributor and submit your own code
+
+## Contributor License Agreements
+
+We'd love to accept your sample apps and patches! Before we can take them, we
+have to jump a couple of legal hurdles.
+
+Please fill out either the individual or corporate Contributor License Agreement (CLA).
+
+  * If you are an individual writing original source code and you're sure you
+    own the intellectual property, then you'll need to sign an [individual CLA]
+    (https://cla.developers.google.com).
+  * If you work for a company that wants to allow you to contribute your work,
+    then you'll need to sign a [corporate CLA]
+    (https://cla.developers.google.com).
+
+Follow either of the two links above to access the appropriate CLA and
+instructions for how to sign and return it. Once we receive it, we'll be able to
+accept your pull requests.
+
+## Contributing A Patch
+
+1. Submit an issue describing your proposed change to the repo in question.
+1. The repo owner will respond to your issue promptly.
+1. If your proposed change is accepted, and you haven't already done so, sign a
+   Contributor License Agreement (see details above).
+1. Fork the desired repo, develop and test your code changes.
+1. Ensure that your code adheres to the existing style in the sample to which
+   you are contributing. Refer to the
+   [Android Code Style Guide]
+   (https://source.android.com/source/code-style.html) for the
+   recommended coding standards for this organization.
+1. Ensure that your code has an appropriate set of unit tests which all pass.
+1. Submit a pull request.

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.

+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"
+      replaced with your own identifying information. (Don't include
+      the brackets!)  The text should be enclosed in the appropriate
+      comment syntax for the file format. We also recommend that a
+      file or class name and description of purpose be included on the
+      same "printed page" as the copyright notice for easier
+      identification within third-party archives.

+Android FloatingActionButtonBasic Sample
+===================================
+
+This sample shows the two sizes of Floating Action Buttons and
+how to interact with them.
+
+Introduction
+------------
+
+This sample shows how to implement a [Checkable][1] Floating Action Button.
+
+Floating action buttons are used for a special type of promoted action.
+They are distinguished by a circled icon floating above the UI and have
+special motion behaviors related to morphing, launching, and the transferring anchor point.
+
+Floating action buttons come in two sizes:
+the default, which should be used in most cases, and the mini,
+which should only be used to create visual continuity with other elements on the screen.
+
+Both sizes of Floating Action Buttons are displayed on screen.
+

 Android FragmentTransition Sample
-==============================
+===================================
 
-This sample demonstrates how to start a transition right after a fragment transaction.
+This sample demonstrates how to start a Transition after a Fragment Transaction.
+
+Introduction
+------------
+
+This sample uses [the Transition framework][1] to show a nice visual effect on
+Fragment Transaction.
+
+Animation for fragment _transaction_ can be customized by overriding
+[onCreateAnimation][2]. In this sample, we set up an AnimationListener
+for this Animation, and start our Transition on [onAnimationEnd][3].
+
+Transition is started by calling [TransitionManager.go][4]. We don't
+instantiate a Scene for the initial state of Transition, as we never
+go back. One thing we need to be careful here is that we need to
+populate the content of Views after starting the Transition.

+# How to become a contributor and submit your own code
+
+## Contributor License Agreements
+
+We'd love to accept your sample apps and patches! Before we can take them, we
+have to jump a couple of legal hurdles.
+
+Please fill out either the individual or corporate Contributor License Agreement (CLA).
+
+  * If you are an individual writing original source code and you're sure you
+    own the intellectual property, then you'll need to sign an [individual CLA]
+    (https://cla.developers.google.com).
+  * If you work for a company that wants to allow you to contribute your work,
+    then you'll need to sign a [corporate CLA]
+    (https://cla.developers.google.com).
+
+Follow either of the two links above to access the appropriate CLA and
+instructions for how to sign and return it. Once we receive it, we'll be able to
+accept your pull requests.
+
+## Contributing A Patch
+
+1. Submit an issue describing your proposed change to the repo in question.
+1. The repo owner will respond to your issue promptly.
+1. If your proposed change is accepted, and you haven't already done so, sign a
+   Contributor License Agreement (see details above).
+1. Fork the desired repo, develop and test your code changes.
+1. Ensure that your code adheres to the existing style in the sample to which
+   you are contributing. Refer to the
+   [Android Code Style Guide]
+   (https://source.android.com/source/code-style.html) for the
+   recommended coding standards for this organization.
+1. Ensure that your code has an appropriate set of unit tests which all pass.
+1. Submit a pull request.

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be

+Android Geofencing Sample
+===================================
+
+When the user enters the vicinity of the Android building (B44) or the Yerba Buena
+Gardens near the Moscone center in San Francisco, a notification silently appears on their
+wearable with an option to check in. This notification automatically disappears when they leave
+the area, and reappears the next time they are at one of these locations.
+
+Introduction
+------------
+
+Geofencing combines awareness of the user's current location with awareness of
+nearby features, defined as the user's proximity to locations that may be of
+interest. To mark a location of interest, you specify its latitude and longitude.
+To adjust the proximity for the location, you add a radius. The latitude,
+longitude, and radius define a geofence. You can have multiple active
+geofences at one time.
+
+To use geofencing, start by defining the geofences you want to monitor.
+Although you usually store geofence data in a local database or download
+it from the network, you need to send a geofence to Location Services as
+an instance of [Geofence][2], which you create with `Geofence.Builder`. Each
+Geofence object contains the following information:
+
+1. Latitude, longitude, and radius
+2. Expiration time
+3. Transition type
+4. Geofence ID
+
+Read more about geofences in [Creating and Monitoring Geofences][1].

+# How to become a contributor and submit your own code
+
+## Contributor License Agreements
+
+We'd love to accept your sample apps and patches! Before we can take them, we
+have to jump a couple of legal hurdles.
+
+Please fill out either the individual or corporate Contributor License Agreement (CLA).
+
+  * If you are an individual writing original source code and you're sure you
+    own the intellectual property, then you'll need to sign an [individual CLA]
+    (https://cla.developers.google.com).
+  * If you work for a company that wants to allow you to contribute your work,
+    then you'll need to sign a [corporate CLA]
+    (https://cla.developers.google.com).
+
+Follow either of the two links above to access the appropriate CLA and
+instructions for how to sign and return it. Once we receive it, we'll be able to
+accept your pull requests.
+
+## Contributing A Patch
+
+1. Submit an issue describing your proposed change to the repo in question.
+1. The repo owner will respond to your issue promptly.
+1. If your proposed change is accepted, and you haven't already done so, sign a
+   Contributor License Agreement (see details above).
+1. Fork the desired repo, develop and test your code changes.
+1. Ensure that your code adheres to the existing style in the sample to which
+   you are contributing. Refer to the
+   [Android Code Style Guide]
+   (https://source.android.com/source/code-style.html) for the
+   recommended coding standards for this organization.
+1. Ensure that your code has an appropriate set of unit tests which all pass.
+1. Submit a pull request.

+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the

+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent

+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and

+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.

 Android HdrViewfinder Sample
-==============================
+===================================
 
-This demo shows how to use Camera2 API and RenderScript to implement an HDR viewfinder.
-
-Introduction
-------------
-
-This demo implements a real-time high-dynamic-range camera viewfinder, by alternating the sensor's
-exposure time between two exposure values on even and odd frames, and then compositing together the
-latest two frames whenever a new frame is captured.
-
-The demo has three modes: Regular auto-exposure viewfinder, split-screen manual exposure, and the
-fused HDR viewfinder.  The latter two use manual exposure controlled by the user, by swiping up/down
-on the right and left halves of the viewfinder.  The left half controls the exposure time of even
-frames, and the right half controls the exposure time of odd frames.
-
-In split-screen mode, the even frames are shown on the left and the odd frames on the right, so the
-user can see two different exposures of the scene simultaneously.  In fused HDR mode, the even/odd
-frames are merged together into a single image.  By selecting different exposure values for the
-even/odd frames, the fused image has a higher dynamic range than the regular viewfinder.
-
-The HDR fusion and the split-screen viewfinder processing is done with RenderScript; as is the
-necessary YUV->RGB conversion. The camera subsystem outputs YUV images naturally, while the GPU and
-display subsystems generally only accept RGB data.  Therefore, after the images are
-fused/composited, a standard YUV->RGB color transform is applied before the the data is written to
-the output Allocation. The HDR fusion algorithm is very simple, and tends to result in
-lower-contrast scenes, but has very few artifacts and can run very fast.
-
-Data is passed between the subsystems (camera, RenderScript, and display) using the Android {@link
-android.view.Surface} class, which allows for zero-copy transport of large buffers between processes
-and subsystems.
+This demo implements a real-time high-dynamic-range camera viewfinder, by alternating
+the sensor's exposure time between two exposure values on even and odd frames, and then
+compositing together the latest two frames whenever a new frame is captured.

 Android HorizontalPaging Sample
-==============================
+===================================
 
-This sample demonstrates how to implement horizontal paging between fragments in
-applications that use ActionBar, using a ViewPager widget.
+This sample shows how to implement tabs, using Fragments and a ViewPager.
+
+Introduction
+------------
+
+This sample implements tabs using the deprecated [ActionBar.TabListener][1]. It uses [ViewPager][2] and
+[FragmentPagerAdapter][3] to handle swiping between tabs and displaying the selected tab content.
+
+
+1. Create an Activity that extends [FragmentActivity][4], with a [ViewPager][2] for its layout.
+2. Implement [ActionBar.TabListener][1] interface.
+3. Create a class that extends [FragmentPagerAdapter][3] and override its `getItem(int position)`,
+`getCount()` and `getPageTitle(int position)` methods.
+4. In the `onCreate(Bundle savedInstanceState)` method of your activity, set navigation mode to tabs for the
+ActionBar using `setNavigationMode(ActionBar.NAVIGATION_MODE_TABS)`. Note: This is DEPRECATED as of Android
+Lollipop.
+5. Set your custom [FragmentPagerAdapter][3] on your [ViewPager][2].
+6. Implement `setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener())` on your [ViewPager][2] to
+know the selected tab, so you can update your ActionBar with `setSelectedNavigationItem(position)`.
+

 Android Interpolator Sample
-==============================
+===================================
 
 This sample demonstrates the use of animation interpolators and path animations for
-Material Design. It shows how an ObjectAnimator is used to animate two properties of a
-view (scale X and Y) along a path.
+`Material Design`.
+
+Introduction
+------------
+
+Material design is a comprehensive guide for visual, motion, and interaction
+design across platforms and devices. Starting with API level 21,
+[Android includes support for material design][1] apps.
+
+This sample demonstrates the use of `Material Design` animation interpolators
+and path animations. It uses an [ObjectAnimator][2] to animate two view properties,
+`Scale_X` and `Scale_Y`. Users can pick from a set of interpolator options. They
+can also define the duration of the animation.

+Android JumpingJack Sample
+===================================
+
+A basic sample showing how to use the Gravity sensor on the wearable device
+by counting how many jumping jacks you have performed.
+
+Introduction
+------------
+
+[SensorEventListener][1] offers you methods used for receiving notifications from the
+[SensorManager][2] when sensor values have changed.
+
+This example counts how many times Jumping Jakcs are performed by detecting the value
+of the Gravity sensor by the following code:
+
+```java
+@Override
+public void onSensorChanged(SensorEvent event) {
+    detectJump(event.values[0], event.timestamp);
+}
+
+private void detectJump(float xValue, long timestamp) {
+    if ((Math.abs(xValue) > GRAVITY_THRESHOLD)) {
+        if(timestamp - mLastTime < TIME_THRESHOLD_NS && mUp != (xValue > 0)) {
+            onJumpDetected(!mUp);
+        }
+        mUp = xValue > 0;
+        mLastTime = timestamp;
+    }
+}
+```
+
+The detectJump method above assumes that when a person is wearing the watch, the x-component of gravity
+as measured by the Gravity Sensor is +9.8 when the hand is downward and -9.8 when the hand
+is upward (signs are reversed if the watch is worn on the right hand). Since the upward or
+downward may not be completely accurate, we leave some room and instead of 9.8, we use
+GRAVITY_THRESHOLD (7.0f). We also consider the up <-> down movement successful if it takes less than
+TIME_THRESHOLD_NS (2000000000 nanoseconds).

-Android RecyclerView Sample
-===========================
+Android LNotifications Sample Sample
+===================================
 
-This sample demonstrates how new features for notifications introduced in Android L
-are used such as Heads-Up notifications, visibility, people, category and priority
-metadata. (Priority metadata has been present since Jelly Bean, but actually unused).
+This sample demonstrates new features for notifications introduced in Android L.
+These features include heads-up notifications, visibility, people, category and priority
+metadata.
+
+Introduction
+------------
+
+Android 5.0 (Lollipop, API level 21) introduced additional features to the Notification API.
+Specifically, it allows developers to specify the priority and visibility level for
+notifications. This metadata allows the system to provide enhanced security for notifications
+while the lock screen is active, allows high-priority notifications to appear even when
+the notification bar is closed, and provides users to silence low-priority notifications
+when they're busy.
+
+This metadata is provided via additional arguments to the `Notification.Builder` class.
+
+Specifically, this sample demonstrates how to generate a heads-up notification
+(`HeadsUpNotificationFragment`), how to control visibility on the lock screen
+(`VisibilityMetadataFragment`), and how to set the category, priority, and associated contact
+for a notification (`OtherMetadataFragment`).

+/**
+ * This class provides a MediaBrowser through a service. It exposes the media library to a browsing
+ * client, through the onGetRoot and onLoadChildren methods. It also creates a MediaSession and
+ * exposes it through its MediaSession.Token, which allows the client to create a MediaController
+ * that connects to and send control commands to the MediaSession remotely. This is useful for
+ * user interfaces that need to interact with your media session, like Android Auto. You can
+ * (should) also use the same service from your app's UI, which gives a seamless playback
+ * experience to the user.
+ *
+ * To implement a MediaBrowserService, you need to:
+ *
+ * <ul>
+ *
+ * <li> Extend {@link android.service.media.MediaBrowserService}, implementing the media browsing
+ *      related methods {@link android.service.media.MediaBrowserService#onGetRoot} and
+ *      {@link android.service.media.MediaBrowserService#onLoadChildren};
+ * <li> In onCreate, start a new {@link android.media.session.MediaSession} and notify its parent
+ *      with the session's token {@link android.service.media.MediaBrowserService#setSessionToken};
+ *
+ * <li> Set a callback on the
+ *      {@link android.media.session.MediaSession#setCallback(android.media.session.MediaSession.Callback)}.
+ *      The callback will receive all the user's actions, like play, pause, etc;
+ *
+ * <li> Handle all the actual music playing using any method your app prefers (for example,
+ *      {@link android.media.MediaPlayer})
+ *
+ * <li> Update playbackState, "now playing" metadata and queue, using MediaSession proper methods
+ *      {@link android.media.session.MediaSession#setPlaybackState(android.media.session.PlaybackState)}
+ *      {@link android.media.session.MediaSession#setMetadata(android.media.MediaMetadata)} and
+ *      {@link android.media.session.MediaSession#setQueue(java.util.List)})
+ *
+ * <li> Declare and export the service in AndroidManifest with an intent receiver for the action
+ *      android.media.browse.MediaBrowserService
+ *
+ * </ul>
+ *
+ * To make your app compatible with Android Auto, you also need to:
+ *
+ * <ul>
+ *
+ * <li> Declare a meta-data tag in AndroidManifest.xml linking to a xml resource
+ *      with a &lt;automotiveApp&gt; root element. For a media app, this must include
+ *      an &lt;uses name="media"/&gt; element as a child.
+ *      For example, in AndroidManifest.xml:
+ *          &lt;meta-data android:name="com.google.android.gms.car.application"
+ *              android:resource="@xml/automotive_app_desc"/&gt;
+ *      And in res/values/automotive_app_desc.xml:
+ *          &lt;automotiveApp&gt;
+ *              &lt;uses name="media"/&gt;
+ *          &lt;/automotiveApp&gt;
+ *
+ * </ul>
+
+ * @see <a href="README.md">README.md</a> for more details.

+Android MediaBrowserService Sample
+===================================
+
+This sample shows how to implement an audio media app that provides
+media library metadata and playback controls through a standard
+service. It exposes a simple music library through the new
+MediaBrowserService and provides MediaSession callbacks. This allows
+it to be used in Android Auto, for example.
+When not connected to a car, the app has a very simple UI that browses
+the media library and provides simple playback controls. When
+connected to Android Auto, the same service provides data and callback
+to the Android Auto UI in the same manner as it provides them to the
+local UI.
+
+Introduction
+------------
+
+To implement a MediaBrowserService, you need to:
+
+- Extend android.service.media.MediaBrowserService, implementing the media
+  browsing related methods onGetRoot and onLoadChildren;
+
+- In onCreate, start a new MediaSession and call super.setSessionToken() with
+  this MediaSession's token;
+
+- Set a MediaSession.Callback class on the MediaSession. The callback class
+  will receive all the user's actions, like play, pause, etc;
+
+- Handle all the actual music playing using any method your app prefers
+  (for example, the Android MediaPlayer class)
+
+- Whenever it changes, update info about the playing item and the playing
+  queue using MediaSession corresponding methods (setMetadata,
+  setPlaybackState, setQueue, setQueueTitle, etc)
+
+- Handle AudioManager focus change events and react appropriately
+  (e.g. pause when audio focus is lost)
+
+
+To make it compatible with Android Auto, you also need to:
+
+- Declare a meta-data tag in AndroidManifest.xml linking to a xml resource
+  with a automotiveApp root element. For a media app, this must include
+  an &lt;uses name="media"/&gt; element as a child.
+
+  For example, in AndroidManifest.xml:
+```
+     <meta-data android:name="com.google.android.gms.car.application"
+       android:resource="@xml/automotive_app_desc"/>
+```
+
+  And in res/xml/automotive\_app\_desc.xml:
+```
+      <?xml version="1.0" encoding="utf-8"?>
+      <automotiveApp>
+          <uses name="media"/>
+      </automotiveApp>
+```
+
+- Declare and export the service in AndroidManifest.xml:
+```
+    <service
+        android:name=".service.MusicService"
+        android:exported="true">
+      <intent-filter>
+         <action android:name="android.media.browse.MediaBrowserService" />
+      </intent-filter>
+    </service>
+```
+
+Pre-requisites
+--------------
+
+- Android SDK v21
+- Android Build Tools v21.1.1
+- Android Support Repository

-Steps to implement FragmentView template:
--in template-params.xml.ftl:
-    -add the following line to common imports
-        <common src="activities"/>
-
--Add a Fragment to show behavior.  In your MainActivity.java class, it will reference a Fragment
- called (yourProjectName)Fragment.java.  Create that file in your project, using the "main" source
- folder instead of "common" or "templates".
-   For instance, if your package name is com.example.foo, create the file
-   src/main/java/com/example/foo/FooFragment.java
-
-
--Within this fragment, make sure that the onCreate method has the line
- "setHasOptionsMenu(true);", to enable the fragment to handle menu events.
-
--In order to override menu events, override onOptionsItemSelected.
-
--refer to sampleSamples/fragmentViewSample for a reference implementation of a
-project built on this template.

+The [Media Effects APIs][1] lets you apply effects to image frames
+represented as OpenGL ES 2.0 textures.  Image frames can be images
+loaded from disk, frames from the device's camera, or other video
+streams.
+
+For a list of available effects, refer to [EffectsFactory][2].
+

 Android MediaRecorder Sample
-==============================
+===================================
 
 This sample uses the camera/camcorder as the A/V source for the MediaRecorder API.
 A TextureView is used as the camera preview which limits the code to API 14+. This
 can be easily replaced with a SurfaceView to run on older devices.
 
+Introduction
+------------
+
+This sample shows how to use the [MediaRecorder][1] API.
+It uses the [Camera][2] as input source and displays a preview on a [TextureView][3]
+The sample features a button to capture the input and stop capturing afterwards.
+
+It demonstrates how to correctly gain control and release the camera.
+The sample also shows how to save the captured audio and video to persistant storage
+and basic error handling.

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.

+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+Android MessagingService Sample
+===================================
+
+This sample shows a simple service that sends notifications using
+NotificationCompat. In addition to sending a notification, it also extends
+the notification with a CarExtender to make it compatible with Android Auto.
+Each unread conversation from a user is sent as a distinct notification.
+
+Introduction
+------------
+
+#### Checklist while building a messaging app that supports Android Auto:
+1. Ensure that Message notifications are extended using
+NotificationCompat.Builder.extend(new CarExtender()...)
+2. Declare a meta-data tag to your AndroidManifest.xml to specify that your app
+is automotive enabled.
+
+example: AndroidManifest.xml
+
+```
+       <meta-data android:name="com.google.android.gms.car.application"
+                   android:resource="@xml/automotive_app_desc"/>
+```
+
+Include the following to indicate that the application wants to show notifications on
+the Android Auto overview screen.
+
+example: res/xml/automotive\_app\_desc.xml
+```
+        <automotiveApp>
+            <uses name="notification"/>
+        </automotiveApp>
+```
+
+#### Flow
+MessagingFragment is shown to the user. Depending on the button clicked, the MessagingService is
+sent a message. MessagingService in turn creates notifications which can be viewed either on the
+device or in the messaging-simulator.
+
+When a message is read, the associated PendingIntent is triggered and MessageReadReceiver is called
+with the appropriate conversationId. Similarly, when a reply is received, the MessageReplyReceiver
+is called with the appropriate conversationId. MessageLogger logs each event and shows them in a
+TextView in MessagingFragment for correlation.

+# How to become a contributor and submit your own code
+
+## Contributor License Agreements
+
+We'd love to accept your sample apps and patches! Before we can take them, we
+have to jump a couple of legal hurdles.
+
+Please fill out either the individual or corporate Contributor License Agreement (CLA).
+
+  * If you are an individual writing original source code and you're sure you
+    own the intellectual property, then you'll need to sign an [individual CLA]
+    (https://cla.developers.google.com).
+  * If you work for a company that wants to allow you to contribute your work,
+    then you'll need to sign a [corporate CLA]
+    (https://cla.developers.google.com).
+
+Follow either of the two links above to access the appropriate CLA and
+instructions for how to sign and return it. Once we receive it, we'll be able to
+accept your pull requests.
+
+## Contributing A Patch
+
+1. Submit an issue describing your proposed change to the repo in question.
+1. The repo owner will respond to your issue promptly.
+1. If your proposed change is accepted, and you haven't already done so, sign a
+   Contributor License Agreement (see details above).
+1. Fork the desired repo, develop and test your code changes.
+1. Ensure that your code adheres to the existing style in the sample to which
+   you are contributing. Refer to the
+   [Android Code Style Guide]
+   (https://source.android.com/source/code-style.html) for the
+   recommended coding standards for this organization.
+1. Ensure that your code has an appropriate set of unit tests which all pass.
+1. Submit a pull request.

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"
+      replaced with your own identifying information. (Don't include
+      the brackets!)  The text should be enclosed in the appropriate
+      comment syntax for the file format. We also recommend that a
+      file or class name and description of purpose be included on the
+      same "printed page" as the copyright notice for easier
+      identification within third-party archives.

+Android Wearable Notifications Sample
+===================================
+
+This sample showcases the available notification styles on a device and wearable.
+
+Introduction
+------------
+
+This sample app enables the user to choose a notification type (the selection is done on the phone),
+which it then displays on the phone and wearable. The notification is built using
+[NotificationCompat.Builder][1] and [NotificationCompat.WearableExtender][2].
+
+See [Creating a Notification][3] for all the details on how to create a notification with wearable features.
+
+On the wearable side, the sample also shows how to create a custom layout using [WearableListView][4].

+Android PdfRendererBasic Sample
+===================================
+
+This sample demonstrates how to display PDF document on screen using
+the PdfRenderer introduced in Android 5.0 Lollipop.
+
+Introduction
+------------
+
+You can now render PDF document pages into bitmap images for printing by using
+the new [PdfRenderer][1] class. You must specify a [ParcelFileDescriptor][2]
+that is seekable (that is, the content can be randomly accessed) on which the
+system writes the the printable content. Your app can obtain a page for
+rendering with [openPage()][3], then call [render()][4] to turn the opened
+[PdfRenderer.Page][5] into a bitmap.
+
+This sample loads the PDF from assets. Contents of assets are compressed by
+default, but we disable it since PdfRenderer class cannot handle it.
+
+```groovy
+android {
+    aaptOptions {
+        noCompress "pdf"
+    }
+}
+```

+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or

+Android PermissionRequest Sample
+===================================
+
+This sample demonstrates how to use the PermissionRequest API to
+securely provide access to restricted system features (such as a
+camera or microphone) from within a WebView. In this example, a dialog
+is created to allow users to explicitly approve or reject each
+request.
+
+Introduction
+------------
+
+PermissionRequest can be used by setting up a custom WebChromeClient.
+
+```java
+mWebView.setWebChromeClient(mWebChromeClient);
+```
+
+In you WebChromeClient implementation, you need to override
+[onPermissionRequest][1]. This method is called when the web content
+is requesting permission to access some resources, providing an
+opportunity to approve or reject the request. In this implementation,
+we display a dialog to allow the user to approve or reject any
+request. In other applications, you may want to implement a whitelist
+of allowed APIs.  Also, override [onPermissionRequestCanceled][2] for
+handling cancellation of the PermissionRequest by the web content.
+
+When the user confirms or denies the request, you can respond back to
+the web content by [grant][3] or [deny][4] respectively.
+
+```java
+mPermissionRequest.grant(mPermissionRequest.getResources());
+```
+
+This sample provides the web content from the assets folder in the
+app. Since WebView is not allowed to use getUserMedia from a "file://"
+URL, the app uses the SimpleWebServer class to provide the content via
+"http://localhost".

+            This sample uses Google Play Services Wearable Data APIs to communicate between
+            applications on a phone and a paired wearable device. Users can create quiz questions on the phone,
+            each of which has an associated DataItem. These DataItems are then received on the wearable, which
+            displays them as notifications. Each notification contains the question as the first page, followed
+            by answers as actions. When an answer is selected, the corresponding question\'s DataItem is updated,
+            which allows the phone application to update the status of the question (i.e. did the user answer it
+            correctly or not) and prompt the next question.

+# How to become a contributor and submit your own code
+
+## Contributor License Agreements
+
+We'd love to accept your sample apps and patches! Before we can take them, we
+have to jump a couple of legal hurdles.
+
+Please fill out either the individual or corporate Contributor License Agreement (CLA).
+
+  * If you are an individual writing original source code and you're sure you
+    own the intellectual property, then you'll need to sign an [individual CLA]
+    (https://cla.developers.google.com).
+  * If you work for a company that wants to allow you to contribute your work,
+    then you'll need to sign a [corporate CLA]
+    (https://cla.developers.google.com).
+
+Follow either of the two links above to access the appropriate CLA and
+instructions for how to sign and return it. Once we receive it, we'll be able to
+accept your pull requests.
+
+## Contributing A Patch
+
+1. Submit an issue describing your proposed change to the repo in question.
+1. The repo owner will respond to your issue promptly.
+1. If your proposed change is accepted, and you haven't already done so, sign a
+   Contributor License Agreement (see details above).
+1. Fork the desired repo, develop and test your code changes.
+1. Ensure that your code adheres to the existing style in the sample to which
+   you are contributing. Refer to the
+   [Android Code Style Guide]
+   (https://source.android.com/source/code-style.html) for the
+   recommended coding standards for this organization.
+1. Ensure that your code has an appropriate set of unit tests which all pass.
+1. Submit a pull request.

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"
+      replaced with your own identifying information. (Don't include
+      the brackets!)  The text should be enclosed in the appropriate
+      comment syntax for the file format. We also recommend that a

+Android Quiz Sample
+===================================
+
+This sample uses Google Play Services Wearable Data APIs to communicate between
+applications on a phone and a paired wearable device. Users can create quiz questions on the phone,
+each of which has an associated DataItem. These DataItems are then received on the wearable, which
+displays them as notifications. Each notification contains the question as the first page, followed
+by answers as actions. When an answer is selected, the corresponding question's DataItem is updated,
+which allows the phone application to update the status of the question (i.e. did the user answer it
+correctly or not) and prompt the next question.
+
+Pre-requisites
+--------------
+
+- Android SDK v21
+- Android Build Tools v21.1.1
+- Android Support Repository
+
+Getting Started
+---------------
+
+This sample uses the Gradle build system. To build this project, use the
+"gradlew build" command or use "Import Project" in Android Studio.

+            from a short list of recipes and select one to view. Each recipe is broken down into a number of
+            steps; when ready, you can click on the START action in the action bar to send the steps to the
+            wearable. On the wearable device, the steps are displayed as a multi-page notification, with one
+            page for each step in the recipe.

+# How to become a contributor and submit your own code
+
+## Contributor License Agreements
+
+We'd love to accept your sample apps and patches! Before we can take them, we
+have to jump a couple of legal hurdles.
+
+Please fill out either the individual or corporate Contributor License Agreement (CLA).
+
+  * If you are an individual writing original source code and you're sure you
+    own the intellectual property, then you'll need to sign an [individual CLA]
+    (https://cla.developers.google.com).
+  * If you work for a company that wants to allow you to contribute your work,
+    then you'll need to sign a [corporate CLA]
+    (https://cla.developers.google.com).
+
+Follow either of the two links above to access the appropriate CLA and
+instructions for how to sign and return it. Once we receive it, we'll be able to
+accept your pull requests.
+
+## Contributing A Patch
+
+1. Submit an issue describing your proposed change to the repo in question.
+1. The repo owner will respond to your issue promptly.
+1. If your proposed change is accepted, and you haven't already done so, sign a
+   Contributor License Agreement (see details above).
+1. Fork the desired repo, develop and test your code changes.
+1. Ensure that your code adheres to the existing style in the sample to which
+   you are contributing. Refer to the
+   [Android Code Style Guide]
+   (https://source.android.com/source/code-style.html) for the
+   recommended coding standards for this organization.
+1. Ensure that your code has an appropriate set of unit tests which all pass.
+1. Submit a pull request.

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.

+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+

+Android RecipeAssistant Sample
+===================================
+
+This phone application uses the enhanced notifications API to display recipe
+instructions using paged notifications. After starting the application on your phone, you can browse
+from a short list of recipes and select one to view. Each recipe is broken down into a number of
+steps; when ready, you can click on the START action in the action bar to send the steps to the
+wearable. On the wearable device, the steps are displayed as a multi-page notification, with one
+page for each step in the recipe.

 Android RenderScriptIntrinsic Sample
-==============================
+===================================
 
 RenderScriptIntrinsic sample that demonstrates how to use RenderScript intrinsics.
 Creates several RenderScript intrinsics and shows a filtering result with various parameters.
 Also shows how to extends RedioButton with StateListDrawable.
 
+Introduction
+------------
+
+[RenderScript][1] is a framework for running computationally intensive tasks at high performance on Android. RenderScript is
+primarily oriented for use with data-parallel computation, although serial computationally intensive workloads can
+benefit as well.
+
+RenderScript **intrinsics** are built-in functions that perform well-defined operations often seen
+in image processing. Intrinsics provide extremely high-performance implementations of standard
+functions with a minimal amount of code.
+
+This sample shows how to access and use the blur, convolve, and matrix intrinsics:
+
+```java
+mScriptBlur = ScriptIntrinsicBlur.create(mRS, Element.U8_4(mRS));
+mScriptConvolve = ScriptIntrinsicConvolve5x5.create(mRS,
+        Element.U8_4(mRS));
+mScriptMatrix = ScriptIntrinsicColorMatrix.create(mRS,
+        Element.U8_4(mRS));
+```
+
+RenderScript intrinsics will usually be the fastest possible way for a developer to perform these operations. The
+Android team works closely with our partners to ensure that the intrinsics perform as fast as possible on their
+architectures — often far beyond anything that can be achieved in a general-purpose language.

+# How to become a contributor and submit your own code
+
+## Contributor License Agreements
+
+We'd love to accept your sample apps and patches! Before we can take them, we
+have to jump a couple of legal hurdles.
+
+Please fill out either the individual or corporate Contributor License Agreement (CLA).
+
+  * If you are an individual writing original source code and you're sure you
+    own the intellectual property, then you'll need to sign an [individual CLA]
+    (https://cla.developers.google.com).
+  * If you work for a company that wants to allow you to contribute your work,
+    then you'll need to sign a [corporate CLA]
+    (https://cla.developers.google.com).
+
+Follow either of the two links above to access the appropriate CLA and
+instructions for how to sign and return it. Once we receive it, we'll be able to
+accept your pull requests.
+
+## Contributing A Patch
+
+1. Submit an issue describing your proposed change to the repo in question.
+1. The repo owner will respond to your issue promptly.
+1. If your proposed change is accepted, and you haven't already done so, sign a
+   Contributor License Agreement (see details above).
+1. Fork the desired repo, develop and test your code changes.
+1. Ensure that your code adheres to the existing style in the sample to which
+   you are contributing. Refer to the
+   [Android Code Style Guide]
+   (https://source.android.com/source/code-style.html) for the
+   recommended coding standards for this organization.
+1. Ensure that your code has an appropriate set of unit tests which all pass.
+1. Submit a pull request.

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION

+      control with that entity. For the purposes of this definition,

+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the

+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent

+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+

+Android ScreenCapture Sample
+===================================
+
+This sample demonstrates how to use Media Projection API to capture device screen in real time and
+show it on a SurfaceView.
+
+Introduction
+------------
+
+Media Projection API lets you capture the current screen through Surface.
+
+To start media projection, you need to get an instance of [MediaProjection][1]. For this, you have
+to call startActivityForResult with an Intent from
+[MediaProjectionManager.createScreenCaptureIntent()][2]. This shows a confirmation dialog to the
+user. When user confirms it, you will get a result code and data in onActivityResult, so pass those
+to [getMediaProjection][3].
+
+Once you get a MediaProjection, use [createVirtualDisplay][4] and bind it to a Surface.
+

+# How to become a contributor and submit your own code
+
+## Contributor License Agreements
+
+We'd love to accept your sample apps and patches! Before we can take them, we
+have to jump a couple of legal hurdles.
+
+Please fill out either the individual or corporate Contributor License Agreement (CLA).
+
+  * If you are an individual writing original source code and you're sure you
+    own the intellectual property, then you'll need to sign an [individual CLA]
+    (https://cla.developers.google.com).
+  * If you work for a company that wants to allow you to contribute your work,
+    then you'll need to sign a [corporate CLA]
+    (https://cla.developers.google.com).
+
+Follow either of the two links above to access the appropriate CLA and
+instructions for how to sign and return it. Once we receive it, we'll be able to
+accept your pull requests.
+
+## Contributing A Patch
+
+1. Submit an issue describing your proposed change to the repo in question.
+1. The repo owner will respond to your issue promptly.
+1. If your proposed change is accepted, and you haven't already done so, sign a
+   Contributor License Agreement (see details above).
+1. Fork the desired repo, develop and test your code changes.
+1. Ensure that your code adheres to the existing style in the sample to which
+   you are contributing. Refer to the
+   [Android Code Style Guide]
+   (https://source.android.com/source/code-style.html) for the
+   recommended coding standards for this organization.
+1. Ensure that your code has an appropriate set of unit tests which all pass.
+1. Submit a pull request.

+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,

+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of

+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and

+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+

+Android SkeletonWearableApp Sample
+===================================
+
+This sample is a basic skeleton app which can be used as a starting point for wear development.
+
+Introduction
+------------
+
+This sample is a mostly empty wearable app that implements a fullscreen activity
+conforming to Android Wear best practices. Included in the sample are examples of [GridViewPager][1],
+[DelayedConfirmationView][2], and [DismissOverlayView][3].
+
+Developers who require a fullscreen activity for
+their wearable app can use this sample as a starting point.

 Android SlidingTabsColors Sample
-==============================
+===================================
 
 A more advanced sample which shows how to use SlidingTabLayout to display a custom
 ViewPager title strip, with custom coloring for each tab.
 
+Introduction
+------------
+
+This sample consists of a custom [HorizontalScrollView][1] called `SlidingTabLayout` that is used
+with a [ViewPager][2] to provide a tab indicator component which gives constant feedback as to
+the user's scroll progress.
+
+The colors can be customized in two ways. The first and simplest is to provide an
+array of colors and the alternative is via the `TabColorizer` interface which gives
+complete control over which color is used for any individual position.
+
+The views used as tabs can be customized by calling `setCustomTabView(int, int)` providing the
+layout ID of the custom layout.

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+

+# How to become a contributor and submit your own code
+
+## Contributor License Agreements
+
+We'd love to accept your sample apps and patches! Before we can take them, we
+have to jump a couple of legal hurdles.
+
+Please fill out either the individual or corporate Contributor License Agreement (CLA).
+
+  * If you are an individual writing original source code and you're sure you
+    own the intellectual property, then you'll need to sign an [individual CLA]
+    (https://cla.developers.google.com).
+  * If you work for a company that wants to allow you to contribute your work,
+    then you'll need to sign a [corporate CLA]
+    (https://cla.developers.google.com).
+
+Follow either of the two links above to access the appropriate CLA and
+instructions for how to sign and return it. Once we receive it, we'll be able to
+accept your pull requests.
+
+## Contributing A Patch

+A sample which shows how to use `SwipeRefreshLayout` to add
+'swipe-to-refresh' gesture to a ListView, enabling the ability to trigger a refresh

+
+Introduction
+------------
+
+A sample which shows how to use
+[SwipeRefreshLayout][1] within a `ListFragment` to add the 'swipe-to-refresh'
+gesture to a `ListView`. The sample provides this functionality by defining a
+re-usable `SwipeRefreshListFragment` class.
+
+The sample displays a list of cheeses. When the user initiates a downward swipe,
+that list refreshes with randomly generated items. Selecting the `Refresh`
+action from the action bar also refreshes the list.

+Android SynchronizedNotifications Sample
+===================================
+
+A basic sample showing how to use simple or synchronized notifications.
+This allows users to dismiss events from either their phone or wearable device simultaneously.
+
+Introduction
+------------
+
+The [DataAPI][1] exposes an API for components to read or write data items and assets between
+the handhelds and wearables. A [DataItem][2] is synchronized across all devices in an Android Wear network.
+It is possible to set data items while not connected to any nodes. Those data items will be synchronized
+when the nodes eventually come online.
+
+This example presents three buttons that would trigger three different combinations of
+notifications on the handset and the watch:
+
+1. The first button builds a simple local-only notification on the handset.
+2. The second one creates a wearable-only notification by putting a data item in the shared data
+store and having a [com.google.android.gms.wearable.WearableListenerService][3] listen for
+that on the wearable.
+3. The third one creates a local notification and a wearable notification by combining the above
+two. It, however, demonstrates how one can set things up so that the dismissal of one
+notification results in the dismissal of the other one.
+
+In the #2 and #3 items, the following code is used to synchronize the data between the handheld
+and the wearable devices using DataAPI.
+
+```java
+PutDataMapRequest putDataMapRequest = PutDataMapRequest.create(path);
+putDataMapRequest.getDataMap().putString(Constants.KEY_CONTENT, content);
+putDataMapRequest.getDataMap().putString(Constants.KEY_TITLE, title);
+PutDataRequest request = putDataMapRequest.asPutDataRequest();
+Wearable.DataApi.putDataItem(mGoogleApiClient, request)
+        .setResultCallback(new ResultCallback<DataApi.DataItemResult>() {
+            @Override
+            public void onResult(DataApi.DataItemResult dataItemResult) {
+                if (!dataItemResult.getStatus().isSuccess()) {
+                    Log.e(TAG, "buildWatchOnlyNotification(): Failed to set the data, "
+                            + "status: " + dataItemResult.getStatus().getStatusCode());
+                }
+            }
+        });
+```

 Android TextLinkify Sample
-==============================
+===================================
 
 This sample illustrates how links can be added to a TextView. This can be done either
 automatically by setting the "autoLink" property or explicitly.
 
+Introduction
+------------
+
+This sample demonstrates how clickable links can be added to a `TextView` in Android.
+
+This can be done in three ways:
+
+- **Automatically:** Text added to a TextView can automatically be linkified by enabling
+autoLinking. In XML, use the `android:autoLink` property, programatically call
+[android.widget.TextView#setAutoLinkMask(int)][1] using an option from
+[android.text.util.Linkify][2].
+- **Parsing a String as HTML:** See [android.text.Html#fromHtml(String)][3].
+- **Manually by constructing a [android.text.SpannableString][4]:** Consisting of
+[android.text.style.StyleSpan][5] and [android.text.style.URLSpan][6] objects that
+are contained within a [android.text.SpannableString][7].
+

+# How to become a contributor and submit your own code
+
+## Contributor License Agreements
+
+We'd love to accept your sample apps and patches! Before we can take them, we
+have to jump a couple of legal hurdles.
+
+Please fill out either the individual or corporate Contributor License Agreement (CLA).
+
+  * If you are an individual writing original source code and you're sure you
+    own the intellectual property, then you'll need to sign an [individual CLA]
+    (https://cla.developers.google.com).
+  * If you work for a company that wants to allow you to contribute your work,
+    then you'll need to sign a [corporate CLA]
+    (https://cla.developers.google.com).
+
+Follow either of the two links above to access the appropriate CLA and
+instructions for how to sign and return it. Once we receive it, we'll be able to
+accept your pull requests.
+
+## Contributing A Patch
+
+1. Submit an issue describing your proposed change to the repo in question.
+1. The repo owner will respond to your issue promptly.
+1. If your proposed change is accepted, and you haven't already done so, sign a
+   Contributor License Agreement (see details above).
+1. Fork the desired repo, develop and test your code changes.
+1. Ensure that your code adheres to the existing style in the sample to which
+   you are contributing. Refer to the
+   [Android Code Style Guide]
+   (https://source.android.com/source/code-style.html) for the
+   recommended coding standards for this organization.

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or

+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+# How to become a contributor and submit your own code
+
+## Contributor License Agreements
+
+We'd love to accept your sample apps and patches! Before we can take them, we
+have to jump a couple of legal hurdles.
+
+Please fill out either the individual or corporate Contributor License Agreement (CLA).
+
+  * If you are an individual writing original source code and you're sure you
+    own the intellectual property, then you'll need to sign an [individual CLA]
+    (https://cla.developers.google.com).
+  * If you work for a company that wants to allow you to contribute your work,
+    then you'll need to sign a [corporate CLA]
+    (https://cla.developers.google.com).
+
+Follow either of the two links above to access the appropriate CLA and
+instructions for how to sign and return it. Once we receive it, we'll be able to
+accept your pull requests.
+
+## Contributing A Patch

+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+Android WatchViewStub Sample
+===================================
+
+This sample demonstrates how to specify different layouts for round and rectangular screens.
+
+Introduction
+------------
+
+It is a basic sample that displays a round layout on a round watch and a rectangular one on a
+rectangular watch.
+
+The corresponding layout is being inflated by the system. This sample shows a way to handle
+this programatically by using a `WatchViewStub.OnLayoutInflateListener`.
+
+Pre-requisites
+--------------
+
+- Android SDK v21
+- Android Build Tools v21.1.1
+- Android Support Repository
+
+Screenshots
+-------------
+
+<img src="screenshots/watch_view_stub_rectangular.png" height="400" alt="Screenshot"/> <img src="screenshots/watch_view_stub_round.png" height="400" alt="Screenshot"/> 
+
+Getting Started
+---------------
+
+This sample uses the Gradle build system. To build this project, use the
+"gradlew build" command or use "Import Project" in Android Studio.

+# How to become a contributor and submit your own code
+
+## Contributor License Agreements
+
+We'd love to accept your sample apps and patches! Before we can take them, we
+have to jump a couple of legal hurdles.
+
+Please fill out either the individual or corporate Contributor License Agreement (CLA).
+
+  * If you are an individual writing original source code and you're sure you
+    own the intellectual property, then you'll need to sign an [individual CLA]
+    (https://cla.developers.google.com).
+  * If you work for a company that wants to allow you to contribute your work,
+    then you'll need to sign a [corporate CLA]
+    (https://cla.developers.google.com).
+
+Follow either of the two links above to access the appropriate CLA and
+instructions for how to sign and return it. Once we receive it, we'll be able to
+accept your pull requests.
+
+## Contributing A Patch
+
+1. Submit an issue describing your proposed change to the repo in question.
+1. The repo owner will respond to your issue promptly.
+1. If your proposed change is accepted, and you haven't already done so, sign a
+   Contributor License Agreement (see details above).
+1. Fork the desired repo, develop and test your code changes.
+1. Ensure that your code adheres to the existing style in the sample to which
+   you are contributing. Refer to the
+   [Android Code Style Guide]
+   (https://source.android.com/source/code-style.html) for the
+   recommended coding standards for this organization.
+1. Ensure that your code has an appropriate set of unit tests which all pass.
+1. Submit a pull request.

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"
+      replaced with your own identifying information. (Don't include
+      the brackets!)  The text should be enclosed in the appropriate
+      comment syntax for the file format. We also recommend that a
+      file or class name and description of purpose be included on the
+      same "printed page" as the copyright notice for easier
+      identification within third-party archives.
