+Sample demonstrating how to advertise small amounts of data using the Bluetooth
+Low Energy API. Also demonstrates how to scan for those Advertisements. (requires
+2 devices to see full operation)
+]]>
+ </description>
+
+ <intro>
+<![CDATA[
+This sample demonstrates use of the Bluetooth Low Energy (BLE) [Advertisement][1] and [Scanning][2] APIs.
+The functionality is split into two fragments - one for Advertising, one for Scanning.
+
+ScannerFragment activates BLE Scanning for 5 seconds and displays a list of found devices which are advertising
+using this sample. It shows the device type, Bluetooth address, and when it was last seen. User can
+refresh to scan again and update the list.
+
+AdvertiserFragment allows the user to toggle BLE Advertising of that device. It broadcasts basic
+information about the device along with a UUID specific to this app so the ScannerFragment on other
+devices can filter by it.
+
+Note: A device cannot detect its own BLE advertisements. You will need two devices to see this
+sample in action.

+ * <li>
+ * When the pre-capture sequence has finished, a {@link CaptureRequest} with a monotonically
+ * increasing request ID set by calls to {@link CaptureRequest.Builder#setTag(Object)} is sent to
+ * the camera to begin the JPEG and RAW capture sequence, and an
+ * {@link ImageSaver.ImageSaverBuilder} is stored for this request in the
+ * {@link #mJpegResultQueue} and {@link #mRawResultQueue}.
+ * </li>
+ * <li>
+ * As {@link CaptureResult}s and {@link Image}s become available via callbacks in a background
+ * thread, a {@link ImageSaver.ImageSaverBuilder} is looked up by the request ID in
+ * {@link #mJpegResultQueue} and {@link #mRawResultQueue} and updated.
+ * </li>
+ * <li>
+ * When all of the necessary results to save an image are available, the an {@link ImageSaver} is
+ * constructed by the {@link ImageSaver.ImageSaverBuilder} and passed to a separate background
+ * thread to save to a file.

+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.

+<![CDATA[
+This sample demonstrates using the Camera2 API to capture a JPEG and RAW sensor frame.
+Check the source code to see a typical example of how to display the camera preview;
+run auto-focus, auto-exposure metering, and auto-white-balance; capture a JPEG and
+RAW image for the same sensor frame; and save these into MediaStore for use in other
+applications.
+]]>
+ </description>
+
+ <intro>
+<![CDATA[
+The [Camera2 API][1] allows users to capture RAW images, i.e. unprocessed pixel data
+directly from the camera sensor that has not yet been converted into a format and
+colorspace typically used for displaying and storing images viewed by humans. The
+[DngCreator][2] class is provided as part of the Camera2 API as a utility for saving
+RAW images as DNG files.
+
+This sample displays a live camera preview in a TextureView, and saves JPEG and DNG
+file for each image captured.

+/**
+ * Demonstrates support for Ambient screens by extending WearableActivity and overriding
+ * onEnterAmbient, onUpdateAmbient, and onExitAmbient.
+ *
+ * There are two modes (Active and Ambient). To trigger future updates (data/screen), we use a
+ * custom Handler for the "Active" mode and an Alarm for the "Ambient" mode.
+ *
+ * Why don't we use just one? Handlers are generally less battery intensive and can be triggered
+ * every second. However, they can not wake up the processor (common in Ambient mode).
+ *
+ * Alarms can wake up the processor (what we need for Ambient), but they struggle with quick updates
+ * (less than one second) and are much less efficient compared to Handlers.
+ *
+ * Therefore, we use Handlers for "Active" mode (can trigger every second and are better on the
+ * battery), and we use Alarms for "Ambient" mode (only need to update once every 20 seconds and
+ * they can wake up a sleeping processor).
+ *
+ * Again, the Activity waits 20 seconds between doing any processing (getting data, updating screen
+ * etc.) while in ambient mode to conserving battery life (processor allowed to sleep). If you can
+ * hold off on updates for a full minute, you can throw away all the Alarm code and just use
+ * onUpdateAmbient() to save even more battery life.
+ *
+ * As always, you will still want to apply the performance guidelines outlined in the Watch Faces
+ * documention to your app.
+ *
+ * Finally, in ambient mode, this Activity follows the same best practices outlined in the
+ * Watch Faces API documentation, e.g., keep most pixels black, avoid large blocks of white pixels,
+ * use only black and white, and disable anti-aliasing.

+ <![CDATA[
+A basic sample showing how to support ambient mode for native Android Wear apps.
+]]>
+ </description>
+
+ <intro>
+ <![CDATA[
+[WearableActivity][1] offers methods for supporting your native app staying on the screen when the Wear device enters ambient mode.
+
+This example extends [WearableActivity][1] and overrides onEnterAmbient, onUpdateAmbient, and onExitAmbient to allow the simple native Wear app to support ambient mode.
+
+In ambient mode, this app follows best practices by keeping most pixels black, avoiding large blocks of white pixels, using only black and white, and disabling anti-aliasing (following the [design guidelines for Watch Faces][2]).
+
+In addition and most importantly, the app sleeps while in ambient mode for 20 seconds between any updates to conserving battery life (processor allowed to sleep). If you can hold off on updates for a full minute, you can throw away the Handler and just use onUpdateAmbient to save even more battery life.
+
+As always, you will still want to apply the [performance guidelines][3] outlined in the Watch Faces documention to your app.
