+    </ol>
+  </div>
+</div>
+
+<p>
+    Google Play services offers a standard authentication flow for all Google APIs and
+    all components of Google Play services. In addition, you can leverage the authentication
+    portion of the Google Play services SDK to authenticate to services that are not yet supported 
+    in the Google Play services platform by using the authentication token to manually make API
+    requests or using a client library provided by the service provider.
+</p>
+
+<p>For implementation details, see the sample in <code>&lt;android-sdk&gt;/extras/google-play-services/samples/auth</code>, which shows you how
+to carry out these basic steps for obtaining an authentication token.</p>
+
+<h2 id="choose">Choosing an Account</h2>
+<p>
+    Google Play services leverage existing accounts on an Android-powered device
+    to authenticate to the services that you want to use. To obtain an authorization token,
+    a valid Google account is required and it must exist on the device. You can ask your users which
+    account they want to use by enumerating the Google accounts on the device or using the
+    built-in 
+<a href="{@docRoot}google/play-services/reference/com/google/android/gms/common/AccountPicker.html">AccountPicker</a>
+    class to display a standard account picker view. You'll need the
+    {@link android.Manifest.permission#GET_ACCOUNTS}
+    permission set in your manifest file for both methods.
+</p>
+<p>
+    For example, here's how to gather all of the Google accounts on a device and return them
+    in an array. When obtaining an authorization token, only the email address of the account is 
+    needed, so that is what the array stores:
+</p>
+
+<pre>
+private String[] getAccountNames() {
+    mAccountManager = AccountManager.get(this);
+    Account[] accounts = mAccountManager.getAccountsByType(
+            GoogleAuthUtil.GOOGLE_ACCOUNT_TYPE);
+    String[] names = new String[accounts.length];
+    for (int i = 0; i &lt; names.length; i++) {
+        names[i] = accounts[i].name;
+    }
+    return names;
+}
+</pre>
+<h2 id="obtain">Obtaining an Authorization Token</h2>
+<p>
+  With an email address, you can now obtain an authorization token. There are two general
+  ways to get a token:</p>
+
+    <ul>
+      <li>Call one of the two overloaded <a href="{@docRoot}google/play-services/reference/com/google/android/gms/auth/GoogleAuthUtil.html#getToken(android.content.Context, java.lang.String, java.lang.String)">GoogleAuthUtil.getToken()</a> methods in a foreground activity where you can
+        display a dialog to the user to interactively handle authentication errors.</li>
+      <li>Call one of the three <a href="{@docRoot}google/play-services/reference/com/google/android/gms/auth/GoogleAuthUtil.html#getTokenWithNotification(android.content.Context, java.lang.String, java.lang.String, android.os.Bundle)">getTokenWithNotification()</a>
+        methods if you are authenticating in a background service or sync adapter so that a notification is displayed if an authentication
+        error occurs.</a></li>
+    </ul>
+
+    <h3>Using getToken()</h3>
+    The following code snippet obtains an authentication token with an email address, the scope that you want to use for the service, and a {@link android.content.Context}:
+<pre>
+HelloActivity mActivity;
+String mEmail;
+String mScope;
+String token;
+
+...
+
+try {
+    token = GoogleAuthUtil.getToken(mActivity, mEmail, mScope);
+} catch {
+    ...
+}
+</pre>
+
+<p>Call this method off of the main UI thread since it executes network transactions. An easy way to do this
+  is in an <a href="http://developer.android.com/reference/android/os/AsyncTask.html">AsyncTask</a>.
+  The sample in the Google Play services SDK shows you how to wrap this call in an AsyncTask.
+  If authentication is successful, the token is returned. If not, the exceptions described in <a href="#handle">Handling Exceptions</a>
+  are thrown that you can catch and handle appropriately.
+</p>
+
+  <h3>Using getTokenWithNotification()</h3>
+  <p>If you are obtaining authentication tokens in a background service or sync adapter, there are three overloaded <code>getTokenWithNotification()</code> methods
+  that you can use:</p>
+  <ul>
+    <li><a href="{@docRoot}google/play-services/reference/com/google/android/gms/auth/GoogleAuthUtil.html#getTokenWithNotification(android.content.Context, java.lang.String, java.lang.String, android.os.Bundle)">getTokenWithNotification(Context context, String accountName, String scope, Bundle extras)</a>:
+    For background services. Displays a notification to the user when authentication errors occur.</li>
+    <li><a href="{@docRoot}google/play-services/reference/com/google/android/gms/auth/GoogleAuthUtil.html#getTokenWithNotification(android.content.Context, java.lang.String, java.lang.String, android.os.Bundle, android.content.Intent)">getTokenWithNotification(Context context, String accountName, String scope, Bundle extras, Intent callback)</a>:
+    This method is for use in background services. It displays a notification to the user when authentication errors occur. If a user clicks the notification and then authorizes the app to access the account, the intent is broadcasted. When using this method:
+    <ul>
+     <li>Create a {@link android.content.BroadcastReceiver} that registers the intent and handles it appropriately</li>
+     <li>In the app's manifest file, set the <code>android:exported</code> attribute to <code>true</code> for the broadcast receiver</li>
+     <li>Ensure that the intent is serializable using the {@link android.content.Intent#toUri toUri(Intent.URI_INTENT_SCHEME)} and
+    {@link android.content.Intent#parseUri parseUri(intentUri, Intent.URI_INTENT_SCHEME)} methods.</li>
+   </ul>
+    <li><a href="{@docRoot}google/play-services/reference/com/google/android/gms/auth/GoogleAuthUtil.html#getTokenWithNotification(android.content.Context, java.lang.String, java.lang.String, android.os.Bundle, java.lang.String, android.os.Bundle)">getTokenWithNotification(Context context, String accountName, String scope, Bundle extras, String authority, Bundle syncBundle)</a>: This method is for use in sync adapters. It displays a notification to the user when authentication errors occur. If a user clicks the notification and then authorizes the app to access the account, the sync adapter retries syncing with the information
+    contained in the <code>syncBundle</code> parameter.</li>
+  </ul>
+  
+   <p>See the sample in <code>&lt;android-sdk&gt;/extras/google-play-services/samples/auth</code> for implementation details.</p>
+
+<h2 id="handle">Handling Exceptions</h2>
+<p>
+    When requesting an authentication token with
+    <a href="{@docRoot}google/play-services/reference/com/google/android/gms/auth/GoogleAuthUtil.html#getToken(android.content.Context, java.lang.String, java.lang.String)">GoogleAuthUtil.getToken()</a>,
+    the following exceptions can be thrown:
+</p>
+<ul>
+    <li>
+<a href="{@docRoot}google/play-services/reference/com/google/android/gms/auth/UserRecoverableAuthException.html">UserRecoverableAuthException</a>: 
+        This exception is thrown when an error occurs that users can resolve, such as not yet granting access to their accounts or if they changed their password.
+        This exception class contains a {@link android.app.Activity#getIntent getIntent()} 
+        method that you can call to obtain an intent that you can use with

+<h2 id="use">Using the Token</h2>
+<p>
+    Once you have successfully obtained a token, you can use it to access Google services.
+    Many Google services provide client libraries, so it is recommended that you use these when 
+    possible, but you can make raw HTTP requests as well with the token. The following example 
+    shows you how to do this and handle HTTP error and success responses accordingly:
+</p>
+
+<pre>
+URL url = new URL("https://www.googleapis.com/oauth2/v1/userinfo?access_token="
+        + token);
+HttpURLConnection con = (HttpURLConnection) url.openConnection();
+int serverCode = con.getResponseCode();
+//successful query
+if (serverCode == 200) {
+    InputStream is = con.getInputStream();
+    String name = getFirstName(readResponse(is));
+    mActivity.show("Hello " + name + "!");
+    is.close();
+    return;
+//bad token, invalidate and get a new one
+} else if (serverCode == 401) {
+    GoogleAuthUtil.invalidateToken(mActivity, token);
+    onError("Server auth error, please try again.", null);
+    Log.e(TAG, "Server auth error: " + readResponse(con.getErrorStream()));
+    return;
+//unknown error, do something else
+} else {
+    Log.e("Server returned the following error code: " + serverCode, null);
+    return;
+}
+</pre>
+
+<p>
+    Notice that you must manually invalidate the token if the response from the server
+    signifies an authentication error (401). This could mean the authentication token
+    being used is invalid for the service's scope or the token may have expired. If this is the 
+    case, obtain a new token using <a href="{@docRoot}google/play-services/reference/com/google/android/gms/auth/GoogleAuthUtil.html#getToken(android.content.Context, java.lang.String, java.lang.String)">GoogleAuthUtil.getToken()</a>.

+
+
+<p>
+    The Google Play services SDK is an extension to the Android SDK and is available to you as a
+    downloadable SDK component. This download includes the client library and code samples.
+</p>
+
+<p>
+    Before you get started developing, make sure that you have an updated version of the Android SDK
+    installed on your computer, including the SDK Tools component. If you don't have the SDK,
+    visit the <a href="{@docRoot}sdk/index.html">SDK Download page</a>
+    on the Android Developers site.
+</p>
+
+<p>
+    To download and configure the Google Play services SDK:
+</p>
+
+<ol>
+    <li>
+        Launch Eclipse and select <b>Window &gt; Android SDK Manager</b> or run <code>android</code>
+        at the command line.
+    </li>
+    <li>
+        Scroll to the bottom of the package list and select <b>Extras &gt; Google Play services</b>.
+        The add-on is downloaded to your computer and installed in your SDK environment at
+        <code>&lt;android-sdk-folder&gt;/extras/google/google_play_services/</code>.
+    </li>
+    <li>
+        Reference the Google Play services client library project located in
+        <code>&lt;android-sdk-folder&gt;/extras/google/google_play_services/libproject/google-play-services_lib</code> as
+        a library project for your Android project. See the

+
+<h2 id="ensure">Ensuring Devices Have the Google Play services APK</h2>
+<p>
+    Google Play delivers updates to the majority of the devices that support Google Play services
+    (Android 2.2 devices with the Google Play Store app installed). However, updates might not reach
+    supported devices in a timely manner, which are desribed in the following four scenarios:
+<p class="note">
+<strong>Important:</strong>
+<span>
+    Because it is hard to anticipate the state devices are in, you must <em>always</em> check for a
+    compatible Google Play services APK in your app when you are accessing Google Play services
+    features.  For many apps, this is each time in the
+    {@link android.app.Activity#onResume onResume()} method of the main activity.
+</span>
+</p>
+<ol>
+    <li>
+        A recent version of the Google Play Store app is installed, and the most recent Google Play
+        services APK has been downloaded.
+    </li>
+    <li>
+        A recent version of the Google Play Store app is installed, but the most recent Google Play
+        services APK has <em>not</em> been downloaded.
+    </li>
+    <li>
+        An old version of the Google Play Store app, which does not proactively download Google Play
+        services updates, is present.
+    </li>
+    <li>
+        The Google Play services APK is missing or disabled on the device, which might happen if the
+        user explicitly uninstalls or disables it.
+    </li>
+</ol>
+<p>
+    Case 1 is the success scenario and is the most common. However, because the other scenarios can
+    still happen, you must handle them every time your app connects to a Google Play service to
+    ensure that the Google Play services APK is present, up-to-date, and enabled.
+</p>
+<p>
+    To help you, the Google Play services client library has utility methods to assist in
+    determining whether or not the Google Play services APK is recent enough to support the
+    version of the client library that you are using.  If not, the client library sends users to the
+    Google Play Store to download a recent version of the Google Play services APK.
+</p>
+
+<p class="note">
+<b>Note:</b>
+<span>
+    The Google Play services APK is not visible by searching the Google Play Store. The client
+    library provides a deep link into the Google Play Store when it detects that the device has a
+    missing or incompatible Google Play services APK.
+</span>
+</p>
+
+<p>
+    It is up to you choose the appropriate place in your app to do the following steps to check for
+    a valid Google Play services APK. For example, if Google Play services is required for your app,
+    you might want to do it when your app first launches. On the other hand, if Google Play services
+    is an optional part of your app, you can do these checks if the user navigates to that portion
+    of your app:
+</p>
+
+<ol>
+    <li>
+        Query for the status of Google Play services on the device with the
+<a href="{@docRoot}google/play-services/reference/com/google/android/gms/common/GooglePlayServicesUtil.html#isGooglePlayServicesAvailable(android.content.Context)">isGooglePlayServicesAvailable()</a>
+        method, which returns a result code.
+    </li>
+    <li>
+        If the result code is
+<a href="{@docRoot}google/play-services/reference/com/google/android/gms/common/ConnectionResult.html#SUCCESS">SUCCESS</a>,
+        then the Google Play services APK is up-to-date, and you can proceed as normal.
+    </li>
+    <li>
+        If the result is
+<a href="{@docRoot}google/play-services/reference/com/google/android/gms/common/ConnectionResult.html#SERVICE_MISSING">SERVICE_MISSING</a>,
+<a href="{@docRoot}google/play-services/reference/com/google/android/gms/common/ConnectionResult.html#SERVICE_VERSION_UPDATE_REQUIRED">SERVICE_VERSION_UPDATE_REQUIRED</a>,
+        or
+<a href="{@docRoot}google/play-services/reference/com/google/android/gms/common/ConnectionResult.html#SERVICE_DISABLED">SERVICE_DISABLED</a>,
+        call <a href="{@docRoot}google/play-services/reference/com/google/android/gms/common/GooglePlayServicesUtil.html#getErrorDialog(int, android.app.Activity, int)">getErrorDialog()</a>
+        to display an error message to the user, which will then allow the user to download the APK
+        from the Google Play Store or enable it in the device's system settings.
+    </li>
+</ol>

+page.title=Overview
+@jd:body
+
+<p>
+Google Play services is a platform delivered by the Google Play Store that offers integration with Google products,
+such as Google+, in Android apps. The Google Play services platform consists of a services component that runs on
+the device and a thin client library that you package with your app. The following diagram shows the interaction
+between the two components:
+</p>
+
+<img src="{@docRoot}images/play-services-diagram.png" />
+
+<p>
+    The Google Play services component is delivered as an APK through the Google Play Store, so
+    updates to Google Play services are not dependent on carrier or OEM system image updates. Newer
+    devices will also have Google Play services as part of the device's system image, but updates
+    are still pushed to these newer devices through the Google Play Store. In general, devices
+    running Android 2.2 (Froyo) or later that have the Google Play Store receive updates within a
+    few days. This allows you to leverage the newest APIs for Google products and reach most of the
+    devices in the Android ecosystem. Devices older than Android 2.2 or devices without the Google
+    Play Store app are not supported.
+</p>
+
+<p>
+    The Google Play services component contains much of the logic to communicate with the specific
+    Google product that you want to interact with. An easy-to-use authentication flow is also
+    provided to gain access to supported Google products, which provides consistency for both the
+    developer and user. From the developer's point of view, requesting credentials is mostly taken
+    care of by the services component through calls to the client library. From the user's point of
+    view, authorization is granted with a few simple clicks.
+</p>
+
+<p>
+    The client library contains the interfaces to call into the services component. It also contains
+    APIs that allow you to resolve any issues at runtime such as a missing, disabled, or out-of-date
+    Google Play services APK. The client library has a light footprint if you use
+    ProGuard as part of your build process, so it won't have an adverse impact on your app's file size. See the
+    <a href="{@docRoot}google/play-services/overview.html">Downloading and Configuring the Google Play services SDK</a> for more
+    information on how to configure
+    <a href="{@docRoot}tools/help/proguard.html">ProGuard</a>.
+</p>
+
+<p>
+    If you want to access added features or products that are periodically added to the client
+    library, you can upgrade to a new version as they are released. However, upgrading is not
+    necessary if you don't care about new features or bug fixes in the new versions of the client
+    library. We anticipate more Google services to be continuously added, so be on the lookout for
+    these updates.

-<p>An Android application will run on a mobile device with limited computing
-power and storage, and constrained battery life. Because of
-this, it should be <em>efficient</em>. Battery life is one reason you might
-want to optimize your app even if it already seems to run "fast enough".
-Battery life is important to users, and Android's battery usage breakdown
-means users will know if your app is responsible draining their battery.</p>
-
-<p>Note that although this document primarily covers micro-optimizations,
-these will almost never make or break your software. Choosing the right
-algorithms and data structures should always be your priority, but is
-outside the scope of this document.</p>
-
-<a name="intro" id="intro"></a>
-<h2>Introduction</h2>
-
-<p>There are two basic rules for writing efficient code:</p>
-<ul>
-    <li>Don't do work that you don't need to do.</li>
-    <li>Don't allocate memory if you can avoid it.</li>
-</ul>
-
-<h2 id="optimize_judiciously">Optimize Judiciously</h2>
-
-<p>This document is about Android-specific micro-optimization, so it assumes
-that you've already used profiling to work out exactly what code needs to be
-optimized, and that you already have a way to measure the effect (good or bad)
-of any changes you make. You only have so much engineering time to invest, so
-it's important to know you're spending it wisely.
-
-<p>(See <a href="#closing_notes">Closing Notes</a> for more on profiling and
-writing effective benchmarks.)
-
-<p>This document also assumes that you made the best decisions about data
-structures and algorithms, and that you've also considered the future
-performance consequences of your API decisions. Using the right data
-structures and algorithms will make more difference than any of the advice
-here, and considering the performance consequences of your API decisions will
-make it easier to switch to better implementations later (this is more
-important for library code than for application code).
-
-<p>(If you need that kind of advice, see Josh Bloch's <em>Effective Java</em>,
-item 47.)</p>
-
-<p>One of the trickiest problems you'll face when micro-optimizing an Android
-app is that your app is pretty much guaranteed to be running on multiple
-hardware platforms. Different versions of the VM running on different
-processors running at different speeds. It's not even generally the case
-that you can simply say "device X is a factor F faster/slower than device Y",
-and scale your results from one device to others. In particular, measurement
-on the emulator tells you very little about performance on any device. There
-are also huge differences between devices with and without a JIT: the "best"
-code for a device with a JIT is not always the best code for a device
-without.</p>
-
-<p>If you want to know how your app performs on a given device, you need to
-test on that device.</p>
-
-<a name="object_creation"></a>
-<h2>Avoid Creating Unnecessary Objects</h2>
-
-<p>Object creation is never free. A generational GC with per-thread allocation
-pools for temporary objects can make allocation cheaper, but allocating memory
-is always more expensive than not allocating memory.</p>
-
-<p>If you allocate objects in a user interface loop, you will force a periodic
-garbage collection, creating little "hiccups" in the user experience. The
-concurrent collector introduced in Gingerbread helps, but unnecessary work
-should always be avoided.</p>
-
-<p>Thus, you should avoid creating object instances you don't need to.  Some
-examples of things that can help:</p>
-
-<ul>
-    <li>If you have a method returning a string, and you know that its result
-    will always be appended to a StringBuffer anyway, change your signature
-    and implementation so that the function does the append directly,
-    instead of creating a short-lived temporary object.</li>
-    <li>When extracting strings from a set of input data, try
-    to return a substring of the original data, instead of creating a copy.
-    You will create a new String object, but it will share the char[]
-    with the data. (The trade-off being that if you're only using a small
-    part of the original input, you'll be keeping it all around in memory
-    anyway if you go this route.)</li>
-</ul>
-
-<p>A somewhat more radical idea is to slice up multidimensional arrays into
-parallel single one-dimension arrays:</p>
-
-<ul>
-    <li>An array of ints is a much better than an array of Integers,
-    but this also generalizes to the fact that two parallel arrays of ints
-    are also a <strong>lot</strong> more efficient than an array of (int,int)
-    objects.  The same goes for any combination of primitive types.</li>
-    <li>If you need to implement a container that stores tuples of (Foo,Bar)
-    objects, try to remember that two parallel Foo[] and Bar[] arrays are
-    generally much better than a single array of custom (Foo,Bar) objects.
-    (The exception to this, of course, is when you're designing an API for
-    other code to access;  in those cases, it's usually better to trade
-    good API design for a small hit in speed. But in your own internal
-    code, you should try and be as efficient as possible.)</li>
-</ul>
-
-<p>Generally speaking, avoid creating short-term temporary objects if you
-can.  Fewer objects created mean less-frequent garbage collection, which has
-a direct impact on user experience.</p>

-<h2>Performance Myths</h2>
-
-<p>Previous versions of this document made various misleading claims. We
-address some of them here.</p>
-
-<p>On devices without a JIT, it is true that invoking methods via a
-variable with an exact type rather than an interface is slightly more
-efficient. (So, for example, it was cheaper to invoke methods on a
-<code>HashMap map</code> than a <code>Map map</code>, even though in both
-cases the map was a <code>HashMap</code>.) It was not the case that this
-was 2x slower; the actual difference was more like 6% slower. Furthermore,
-the JIT makes the two effectively indistinguishable.</p>
-
-<p>On devices without a JIT, caching field accesses is about 20% faster than
-repeatedly accesssing the field. With a JIT, field access costs about the same
-as local access, so this isn't a worthwhile optimization unless you feel it
-makes your code easier to read. (This is true of final, static, and static
-final fields too.)
-
-<a name="prefer_static" id="prefer_static"></a>
-<h2>Prefer Static Over Virtual</h2>
-
-<p>If you don't need to access an object's fields, make your method static.
-Invocations will be about 15%-20% faster.
-It's also good practice, because you can tell from the method
-signature that calling the method can't alter the object's state.</p>
-
-<a name="internal_get_set" id="internal_get_set"></a>
-<h2>Avoid Internal Getters/Setters</h2>
-
-<p>In native languages like C++ it's common practice to use getters (e.g.
-<code>i = getCount()</code>) instead of accessing the field directly (<code>i
-= mCount</code>). This is an excellent habit for C++, because the compiler can
-usually inline the access, and if you need to restrict or debug field access
-you can add the code at any time.</p>
-
-<p>On Android, this is a bad idea.  Virtual method calls are expensive,
-much more so than instance field lookups.  It's reasonable to follow
-common object-oriented programming practices and have getters and setters
-in the public interface, but within a class you should always access
-fields directly.</p>
-
-<p>Without a JIT, direct field access is about 3x faster than invoking a
-trivial getter. With the JIT (where direct field access is as cheap as
-accessing a local), direct field access is about 7x faster than invoking a
-trivial getter. This is true in Froyo, but will improve in the future when
-the JIT inlines getter methods.</p>
-
-<p>Note that if you're using ProGuard, you can have the best
-of both worlds because ProGuard can inline accessors for you.</p>
-
-<a name="use_final" id="use_final"></a>
-<h2>Use Static Final For Constants</h2>
-
-<p>Consider the following declaration at the top of a class:</p>
-
-<pre>static int intVal = 42;
-static String strVal = "Hello, world!";</pre>
-
-<p>The compiler generates a class initializer method, called
-<code>&lt;clinit&gt;</code>, that is executed when the class is first used.
-The method stores the value 42 into <code>intVal</code>, and extracts a
-reference from the classfile string constant table for <code>strVal</code>.
-When these values are referenced later on, they are accessed with field
-lookups.</p>
-
-<p>We can improve matters with the "final" keyword:</p>
-
-<pre>static final int intVal = 42;
-static final String strVal = "Hello, world!";</pre>
-
-<p>The class no longer requires a <code>&lt;clinit&gt;</code> method,
-because the constants go into static field initializers in the dex file.
-Code that refers to <code>intVal</code> will use
-the integer value 42 directly, and accesses to <code>strVal</code> will
-use a relatively inexpensive "string constant" instruction instead of a
-field lookup. (Note that this optimization only applies to primitive types and
-<code>String</code> constants, not arbitrary reference types. Still, it's good
-practice to declare constants <code>static final</code> whenever possible.)</p>
-
-<a name="foreach" id="foreach"></a>
-<h2>Use Enhanced For Loop Syntax</h2>
-
-<p>The enhanced for loop (also sometimes known as "for-each" loop) can be used
-for collections that implement the Iterable interface and for arrays.
-With collections, an iterator is allocated to make interface calls
-to hasNext() and next(). With an ArrayList, a hand-written counted loop is
-about 3x faster (with or without JIT), but for other collections the enhanced
-for loop syntax will be exactly equivalent to explicit iterator usage.</p>
-
-<p>There are several alternatives for iterating through an array:</p>
-
-<pre>    static class Foo {
-        int mSplat;
-    }
-    Foo[] mArray = ...
-
-    public void zero() {
-        int sum = 0;
-        for (int i = 0; i &lt; mArray.length; ++i) {
-            sum += mArray[i].mSplat;
-        }
-    }
-
-    public void one() {
-        int sum = 0;
-        Foo[] localArray = mArray;
-        int len = localArray.length;
-
-        for (int i = 0; i &lt; len; ++i) {
-            sum += localArray[i].mSplat;
-        }
-    }
-
-    public void two() {
-        int sum = 0;
-        for (Foo a : mArray) {
-            sum += a.mSplat;
-        }
-    }
-</pre>
-
-<p><strong>zero()</strong> is slowest, because the JIT can't yet optimize away
-the cost of getting the array length once for every iteration through the
-loop.</p>
-
-<p><strong>one()</strong> is faster. It pulls everything out into local
-variables, avoiding the lookups. Only the array length offers a performance
-benefit.</p>
-
-<p><strong>two()</strong> is fastest for devices without a JIT, and
-indistinguishable from <strong>one()</strong> for devices with a JIT.
-It uses the enhanced for loop syntax introduced in version 1.5 of the Java
-programming language.</p>
-
-<p>To summarize: use the enhanced for loop by default, but consider a
-hand-written counted loop for performance-critical ArrayList iteration.</p>
-
-<p>(See also <em>Effective Java</em> item 46.)</p>
-
-<a name="package_inner" id="package_inner"></a>
-<h2>Consider Package Instead of Private Access with Private Inner Classes</h2>
-
-<p>Consider the following class definition:</p>
-
-<pre>public class Foo {
-    private class Inner {
-        void stuff() {
-            Foo.this.doStuff(Foo.this.mValue);
-        }
-    }
-
-    private int mValue;
-
-    public void run() {
-        Inner in = new Inner();
-        mValue = 27;
-        in.stuff();
-    }
-
-    private void doStuff(int value) {
-        System.out.println("Value is " + value);
-    }
-}</pre>
-
-<p>The key things to note here are that we define a private inner class
-(<code>Foo$Inner</code>) that directly accesses a private method and a private
-instance field in the outer class. This is legal, and the code prints "Value is
-27" as expected.</p>
-
-<p>The problem is that the VM considers direct access to <code>Foo</code>'s
-private members from <code>Foo$Inner</code> to be illegal because
-<code>Foo</code> and <code>Foo$Inner</code> are different classes, even though
-the Java language allows an inner class to access an outer class' private
-members. To bridge the gap, the compiler generates a couple of synthetic
-methods:</p>
-
-<pre>/*package*/ static int Foo.access$100(Foo foo) {
-    return foo.mValue;
-}
-/*package*/ static void Foo.access$200(Foo foo, int value) {
-    foo.doStuff(value);
-}</pre>
-
-<p>The inner class code calls these static methods whenever it needs to
-access the <code>mValue</code> field or invoke the <code>doStuff</code> method
-in the outer class. What this means is that the code above really boils down to
-a case where you're accessing member fields through accessor methods.
-Earlier we talked about how accessors are slower than direct field
-accesses, so this is an example of a certain language idiom resulting in an
-"invisible" performance hit.</p>
-
-<p>If you're using code like this in a performance hotspot, you can avoid the
-overhead by declaring fields and methods accessed by inner classes to have
-package access, rather than private access. Unfortunately this means the fields
-can be accessed directly by other classes in the same package, so you shouldn't
-use this in public API.</p>
-
-<a name="avoidfloat" id="avoidfloat"></a>
-<h2>Use Floating-Point Judiciously</h2>
-
-<p>As a rule of thumb, floating-point is about 2x slower than integer on
-Android devices. This is true on a FPU-less, JIT-less G1 and a Nexus One with
-an FPU and the JIT. (Of course, absolute speed difference between those two
-devices is about 10x for arithmetic operations.)</p>
-
-<p>In speed terms, there's no difference between <code>float</code> and
-<code>double</code> on the more modern hardware. Space-wise, <code>double</code>
-is 2x larger. As with desktop machines, assuming space isn't an issue, you
-should prefer <code>double</code> to <code>float</code>.</p>
-
-<p>Also, even for integers, some chips have hardware multiply but lack
-hardware divide. In such cases, integer division and modulus operations are
-performed in software &mdash; something to think about if you're designing a
-hash table or doing lots of math.</p>
-
-<a name="library" id="library"></a>
-<h2>Know And Use The Libraries</h2>
-
-<p>In addition to all the usual reasons to prefer library code over rolling
-your own, bear in mind that the system is at liberty to replace calls
-to library methods with hand-coded assembler, which may be better than the
-best code the JIT can produce for the equivalent Java. The typical example
-here is <code>String.indexOf</code> and friends, which Dalvik replaces with
-an inlined intrinsic. Similarly, the <code>System.arraycopy</code> method
-is about 9x faster than a hand-coded loop on a Nexus One with the JIT.</p>
-
-<p>(See also <em>Effective Java</em> item 47.)</p>
-
-<a name="native_methods" id="native_methods"></a>
-<h2>Use Native Methods Judiciously</h2>
-
-<p>Native code isn't necessarily more efficient than Java. For one thing,
-there's a cost associated with the Java-native transition, and the JIT can't
-optimize across these boundaries. If you're allocating native resources (memory
-on the native heap, file descriptors, or whatever), it can be significantly
-more difficult to arrange timely collection of these resources. You also
-need to compile your code for each architecture you wish to run on (rather
-than rely on it having a JIT). You may even have to compile multiple versions
-for what you consider the same architecture: native code compiled for the ARM
-processor in the G1 can't take full advantage of the ARM in the Nexus One, and
-code compiled for the ARM in the Nexus One won't run on the ARM in the G1.</p>
-
-<p>Native code is primarily useful when you have an existing native codebase
-that you want to port to Android, not for "speeding up" parts of a Java app.</p>
-
-<p>If you do need to use native code, you should read our
-<a href="{@docRoot}guide/practices/jni.html">JNI Tips</a>.</p>
-
-<p>(See also <em>Effective Java</em> item 54.)</p>
-
-<a name="closing_notes" id="closing_notes"></a>
-<h2>Closing Notes</h2>
-
-<p>One last thing: always measure. Before you start optimizing, make sure you
-have a problem. Make sure you can accurately measure your existing performance,
-or you won't be able to measure the benefit of the alternatives you try.</p>
-
-<p>Every claim made in this document is backed up by a benchmark. The source
-to these benchmarks can be found in the <a href="http://code.google.com/p/dalvik/source/browse/#svn/trunk/benchmarks">code.google.com "dalvik" project</a>.</p>
-
-<p>The benchmarks are built with the
-<a href="http://code.google.com/p/caliper/">Caliper</a> microbenchmarking
-framework for Java. Microbenchmarks are hard to get right, so Caliper goes out
-of its way to do the hard work for you, and even detect some cases where you're
-not measuring what you think you're measuring (because, say, the VM has
-managed to optimize all your code away). We highly recommend you use Caliper
-to run your own microbenchmarks.</p>
-
-<p>You may also find
-<a href="{@docRoot}tools/debugging/debugging-tracing.html">Traceview</a> useful
-for profiling, but it's important to realize that it currently disables the JIT,
-which may cause it to misattribute time to code that the JIT may be able to win
-back. It's especially important after making changes suggested by Traceview
-data to ensure that the resulting code actually runs faster when run without
-Traceview.

-<p><strong>Figure 1.</strong> An ANR dialog displayed to the user.</p>
-</div>
-
-<p>It's possible to write code that wins every performance test in the world,
-but still sends users in a fiery rage when they try to use the application.
-These are the applications that aren't <em>responsive</em> enough &mdash; the
-ones that feel sluggish, hang or freeze for significant periods, or take too
-long to process input. </p>
-
-<p>In Android, the system guards against applications that are insufficiently
-responsive for a period of time by displaying a dialog to the user, called the
-Application Not Responding (ANR) dialog, shown at right in Figure 1. The user
-can choose to let the application continue, but the user won't appreciate having
-to act on this dialog every time he or she uses your application. It's critical
-to design responsiveness into your application, so that the system never has
-cause to display an ANR dialog to the user. </p>
-
-<p>Generally, the system displays an ANR if an application cannot respond to
-user input. For example, if an  application blocks on some I/O operation
-(frequently a network access), then the main application thread won't be able to
-process incoming user input events. After a time, the system concludes that the
-application is frozen, and displays the ANR to give the user the option to kill
-it. </p>
-
-<p>Similarly, if your application spends too much time building an elaborate in-memory
-structure, or perhaps computing the next move in a game, the system will 
-conclude that your application has hung. It's always important to make
-sure these computations are efficient using the techniques above, but even the
-most efficient code still takes time to run.</p>
-
-<p>In both of these cases, the recommended approach is to create a child thread and do
-most of your work there. This keeps the main thread (which drives the user
-interface event loop) running and prevents the system from concluding that your code
-has frozen. Since such threading usually is accomplished at the class
-level, you can think of responsiveness as a <em>class</em> problem. (Compare
-this with basic performance, which was described above as a <em>method</em>-level
-concern.)</p>
-
-<p>This document describes how the Android system determines whether an
-application is not responding and provides guidelines for ensuring that your
-application stays responsive. </p>
-
-<h2 id="anr">What Triggers ANR?</h2>
-
-<p>In Android, application responsiveness is monitored by the Activity Manager
-and Window Manager system services. Android will display the ANR dialog
-for a particular application when it detects one of the following
-conditions:</p>
-<ul>  
-    <li>No response to an input event (e.g. key press, screen touch) 
-    within 5 seconds</li>
-    <li>A {@link android.content.BroadcastReceiver BroadcastReceiver} 
-    hasn't finished executing within 10 seconds</li>
-</ul>
-
-<h2 id="avoiding">How to Avoid ANR</h2>
-
-<p>Given the above definition for ANR, let's examine why this can occur in
-Android applications and how best to structure your application to avoid ANR.</p>
-
-<p>Android applications normally run entirely on a single (i.e. main) thread.
-This means that anything your application is doing in the main thread that
-takes a long time to complete can trigger the ANR dialog because your
-application is not giving itself a chance to handle the input event or Intent
-broadcast.</p>
-
-<p>Therefore any method that runs in the main thread should do as little work
-as possible. In particular, Activities should do as little as possible to set
-up in key life-cycle methods such as <code>onCreate()</code> and
-<code>onResume()</code>. Potentially long running operations such as network
-or database operations, or computationally expensive calculations such as
-resizing bitmaps should be done in a child thread (or in the case of databases
-operations, via an asynchronous request). However, this does not mean that
-your main thread should block while waiting for the child thread to
-complete &mdash; nor should you call <code>Thread.wait()</code> or
-<code>Thread.sleep()</code>. Instead of blocking while waiting for a child
-thread to complete, your main thread should provide a {@link
-android.os.Handler Handler} for child threads to post back to upon completion.
-Designing your application in this way will allow your main thread to remain
-responsive to input and thus avoid ANR dialogs caused by the 5 second input
-event timeout. These same practices should be followed for any other threads
-that display UI, as they are also subject to the same timeouts.</p>
-
-<p>You can use {@link android.os.StrictMode} to help find potentially
-long running operations such as network or database operations that
-you might accidentally be doing your main thread.</p>
-
-<p>The specific constraint on IntentReceiver execution time emphasizes what
-they were meant to do: small, discrete amounts of work in the background such
-as saving a setting or registering a Notification. So as with other methods
-called in the main thread, applications should avoid potentially long-running
-operations or calculations in BroadcastReceivers. But instead of doing intensive
-tasks via child threads (as the life of a BroadcastReceiver is short), your
-application should start a {@link android.app.Service Service} if a
-potentially long running action needs to be taken in response to an Intent
-broadcast. As a side note, you should also avoid starting an Activity from an
-Intent Receiver, as it will spawn a new screen that will steal focus from
-whatever application the user is currently has running. If your application
-has something to show the user in response to an Intent broadcast, it should
-do so using the {@link android.app.NotificationManager Notification
-Manager}.</p>
-
-<h2 id="reinforcing">Reinforcing Responsiveness</h2>
-
-<p>Generally, 100 to 200ms is the threshold beyond which users will perceive
-lag (or lack of "snappiness," if you will) in an application. As such, here
-are some additional tips beyond what you should do to avoid ANR that will help
-make your application seem responsive to users.</p>
-
-<ul>
-    <li>If your application is doing work in the background in response to
-    user input, show that progress is being made ({@link
-    android.widget.ProgressBar ProgressBar} and {@link
-    android.app.ProgressDialog ProgressDialog} are useful for this).</li>
-    <li>For games specifically, do calculations for moves in a child
-    thread.</li>
-    <li>If your application has a time-consuming initial setup phase, consider
-    showing a splash screen or rendering the main view as quickly as possible
-    and filling in the information asynchronously. In either case, you should
-    indicate somehow that progress is being made, lest the user perceive that
-    the application is frozen.</li>

-<p>An Android application will run on a mobile device with limited computing
-power and storage, and constrained battery life. Because of
-this, it should be <em>efficient</em>. Battery life is one reason you might
-want to optimize your app even if it already seems to run "fast enough".
-Battery life is important to users, and Android's battery usage breakdown
-means users will know if your app is responsible draining their battery.</p>
-
-<p>Note that although this document primarily covers micro-optimizations,
-these will almost never make or break your software. Choosing the right
-algorithms and data structures should always be your priority, but is
-outside the scope of this document.</p>
-
-<a name="intro" id="intro"></a>
-<h2>Introduction</h2>
-
-<p>There are two basic rules for writing efficient code:</p>
-<ul>
-    <li>Don't do work that you don't need to do.</li>
-    <li>Don't allocate memory if you can avoid it.</li>
-</ul>
-
-<h2 id="optimize_judiciously">Optimize Judiciously</h2>
-
-<p>This document is about Android-specific micro-optimization, so it assumes
-that you've already used profiling to work out exactly what code needs to be
-optimized, and that you already have a way to measure the effect (good or bad)
-of any changes you make. You only have so much engineering time to invest, so
-it's important to know you're spending it wisely.
-
-<p>(See <a href="#closing_notes">Closing Notes</a> for more on profiling and
-writing effective benchmarks.)
-
-<p>This document also assumes that you made the best decisions about data
-structures and algorithms, and that you've also considered the future
-performance consequences of your API decisions. Using the right data
-structures and algorithms will make more difference than any of the advice
-here, and considering the performance consequences of your API decisions will
-make it easier to switch to better implementations later (this is more
-important for library code than for application code).
-
-<p>(If you need that kind of advice, see Josh Bloch's <em>Effective Java</em>,
-item 47.)</p>
-
-<p>One of the trickiest problems you'll face when micro-optimizing an Android
-app is that your app is pretty much guaranteed to be running on multiple
-hardware platforms. Different versions of the VM running on different
-processors running at different speeds. It's not even generally the case
-that you can simply say "device X is a factor F faster/slower than device Y",
-and scale your results from one device to others. In particular, measurement
-on the emulator tells you very little about performance on any device. There
-are also huge differences between devices with and without a JIT: the "best"
-code for a device with a JIT is not always the best code for a device
-without.</p>
-
-<p>If you want to know how your app performs on a given device, you need to
-test on that device.</p>
-
-<a name="object_creation"></a>
-<h2>Avoid Creating Unnecessary Objects</h2>
-
-<p>Object creation is never free. A generational GC with per-thread allocation
-pools for temporary objects can make allocation cheaper, but allocating memory
-is always more expensive than not allocating memory.</p>
-
-<p>If you allocate objects in a user interface loop, you will force a periodic
-garbage collection, creating little "hiccups" in the user experience. The
-concurrent collector introduced in Gingerbread helps, but unnecessary work
-should always be avoided.</p>
-
-<p>Thus, you should avoid creating object instances you don't need to.  Some
-examples of things that can help:</p>
-
-<ul>
-    <li>If you have a method returning a string, and you know that its result
-    will always be appended to a StringBuffer anyway, change your signature
-    and implementation so that the function does the append directly,
-    instead of creating a short-lived temporary object.</li>
-    <li>When extracting strings from a set of input data, try
-    to return a substring of the original data, instead of creating a copy.
-    You will create a new String object, but it will share the char[]
-    with the data. (The trade-off being that if you're only using a small
-    part of the original input, you'll be keeping it all around in memory
-    anyway if you go this route.)</li>
-</ul>
-
-<p>A somewhat more radical idea is to slice up multidimensional arrays into
-parallel single one-dimension arrays:</p>
-
-<ul>
-    <li>An array of ints is a much better than an array of Integers,
-    but this also generalizes to the fact that two parallel arrays of ints
-    are also a <strong>lot</strong> more efficient than an array of (int,int)
-    objects.  The same goes for any combination of primitive types.</li>
-    <li>If you need to implement a container that stores tuples of (Foo,Bar)
-    objects, try to remember that two parallel Foo[] and Bar[] arrays are
-    generally much better than a single array of custom (Foo,Bar) objects.
-    (The exception to this, of course, is when you're designing an API for
-    other code to access;  in those cases, it's usually better to trade
-    good API design for a small hit in speed. But in your own internal
-    code, you should try and be as efficient as possible.)</li>
-</ul>
-
-<p>Generally speaking, avoid creating short-term temporary objects if you
-can.  Fewer objects created mean less-frequent garbage collection, which has
-a direct impact on user experience.</p>

-<h2>Performance Myths</h2>
-
-<p>Previous versions of this document made various misleading claims. We
-address some of them here.</p>
-
-<p>On devices without a JIT, it is true that invoking methods via a
-variable with an exact type rather than an interface is slightly more
-efficient. (So, for example, it was cheaper to invoke methods on a
-<code>HashMap map</code> than a <code>Map map</code>, even though in both
-cases the map was a <code>HashMap</code>.) It was not the case that this
-was 2x slower; the actual difference was more like 6% slower. Furthermore,
-the JIT makes the two effectively indistinguishable.</p>
-
-<p>On devices without a JIT, caching field accesses is about 20% faster than
-repeatedly accesssing the field. With a JIT, field access costs about the same
-as local access, so this isn't a worthwhile optimization unless you feel it
-makes your code easier to read. (This is true of final, static, and static
-final fields too.)
-
-<a name="prefer_static" id="prefer_static"></a>
-<h2>Prefer Static Over Virtual</h2>
-
-<p>If you don't need to access an object's fields, make your method static.
-Invocations will be about 15%-20% faster.
-It's also good practice, because you can tell from the method
-signature that calling the method can't alter the object's state.</p>
-
-<a name="internal_get_set" id="internal_get_set"></a>
-<h2>Avoid Internal Getters/Setters</h2>
-
-<p>In native languages like C++ it's common practice to use getters (e.g.
-<code>i = getCount()</code>) instead of accessing the field directly (<code>i
-= mCount</code>). This is an excellent habit for C++, because the compiler can
-usually inline the access, and if you need to restrict or debug field access
-you can add the code at any time.</p>
-
-<p>On Android, this can be a bad idea.  Virtual method calls can be more
-expensive than instance field lookups.  It's reasonable to follow
-common object-oriented programming practices and have getters and setters
-in the public interface, but within a class you might want to access
-fields directly.</p>
-
-<p>Without a JIT, direct field access is about 3x faster than invoking a
-trivial getter (one that simply returns the value of a field, without
-any dereferencing or array indexing). With the Froyo JIT, direct field
-access was about 7x faster than invoking a trivial getter. Since
-Gingerbread, though, the JIT inlines trivial getter methods, making
-that particular optimization obsolete. Manual inlining guided by
-profiling can still be a useful technique in general, though.</a>
-
-<p>Note that if you're using ProGuard, you can have the best
-of both worlds even with non-trival accessors, because ProGuard can inline
-for you.</p>
-
-<a name="use_final" id="use_final"></a>
-<h2>Use Static Final For Constants</h2>
-
-<p>Consider the following declaration at the top of a class:</p>
-
-<pre>static int intVal = 42;
-static String strVal = "Hello, world!";</pre>
-
-<p>The compiler generates a class initializer method, called
-<code>&lt;clinit&gt;</code>, that is executed when the class is first used.
-The method stores the value 42 into <code>intVal</code>, and extracts a
-reference from the classfile string constant table for <code>strVal</code>.
-When these values are referenced later on, they are accessed with field
-lookups.</p>
-
-<p>We can improve matters with the "final" keyword:</p>
-
-<pre>static final int intVal = 42;
-static final String strVal = "Hello, world!";</pre>
-
-<p>The class no longer requires a <code>&lt;clinit&gt;</code> method,
-because the constants go into static field initializers in the dex file.
-Code that refers to <code>intVal</code> will use
-the integer value 42 directly, and accesses to <code>strVal</code> will
-use a relatively inexpensive "string constant" instruction instead of a
-field lookup. (Note that this optimization only applies to primitive types and
-<code>String</code> constants, not arbitrary reference types. Still, it's good
-practice to declare constants <code>static final</code> whenever possible.)</p>
-
-<a name="foreach" id="foreach"></a>
-<h2>Use Enhanced For Loop Syntax</h2>
-
-<p>The enhanced for loop (also sometimes known as "for-each" loop) can be used
-for collections that implement the Iterable interface and for arrays.
-With collections, an iterator is allocated to make interface calls
-to hasNext() and next(). With an ArrayList, a hand-written counted loop is
-about 3x faster (with or without JIT), but for other collections the enhanced
-for loop syntax will be exactly equivalent to explicit iterator usage.</p>
-
-<p>There are several alternatives for iterating through an array:</p>
-
-<pre>    static class Foo {
-        int mSplat;
-    }
-    Foo[] mArray = ...
-
-    public void zero() {
-        int sum = 0;
-        for (int i = 0; i &lt; mArray.length; ++i) {
-            sum += mArray[i].mSplat;
-        }
-    }
-
-    public void one() {
-        int sum = 0;
-        Foo[] localArray = mArray;
-        int len = localArray.length;
-
-        for (int i = 0; i &lt; len; ++i) {
-            sum += localArray[i].mSplat;
-        }
-    }
-
-    public void two() {
-        int sum = 0;
-        for (Foo a : mArray) {
-            sum += a.mSplat;
-        }
-    }
-</pre>
-
-<p><strong>zero()</strong> is slowest, because the JIT can't yet optimize away
-the cost of getting the array length once for every iteration through the
-loop.</p>
-
-<p><strong>one()</strong> is faster. It pulls everything out into local
-variables, avoiding the lookups. Only the array length offers a performance
-benefit.</p>
-
-<p><strong>two()</strong> is fastest for devices without a JIT, and
-indistinguishable from <strong>one()</strong> for devices with a JIT.
-It uses the enhanced for loop syntax introduced in version 1.5 of the Java
-programming language.</p>
-
-<p>To summarize: use the enhanced for loop by default, but consider a
-hand-written counted loop for performance-critical ArrayList iteration.</p>
-
-<p>(See also <em>Effective Java</em> item 46.)</p>
-
-<a name="package_inner" id="package_inner"></a>
-<h2>Consider Package Instead of Private Access with Private Inner Classes</h2>
-
-<p>Consider the following class definition:</p>
-
-<pre>public class Foo {
-    private class Inner {
-        void stuff() {
-            Foo.this.doStuff(Foo.this.mValue);
-        }
-    }
-
-    private int mValue;
-
-    public void run() {
-        Inner in = new Inner();
-        mValue = 27;
-        in.stuff();
-    }
-
-    private void doStuff(int value) {
-        System.out.println("Value is " + value);
-    }
-}</pre>
-
-<p>The key things to note here are that we define a private inner class
-(<code>Foo$Inner</code>) that directly accesses a private method and a private
-instance field in the outer class. This is legal, and the code prints "Value is
-27" as expected.</p>
-
-<p>The problem is that the VM considers direct access to <code>Foo</code>'s
-private members from <code>Foo$Inner</code> to be illegal because
-<code>Foo</code> and <code>Foo$Inner</code> are different classes, even though
-the Java language allows an inner class to access an outer class' private
-members. To bridge the gap, the compiler generates a couple of synthetic
-methods:</p>
-
-<pre>/*package*/ static int Foo.access$100(Foo foo) {
-    return foo.mValue;
-}
-/*package*/ static void Foo.access$200(Foo foo, int value) {
-    foo.doStuff(value);
-}</pre>
-
-<p>The inner class code calls these static methods whenever it needs to
-access the <code>mValue</code> field or invoke the <code>doStuff</code> method
-in the outer class. What this means is that the code above really boils down to
-a case where you're accessing member fields through accessor methods.
-Earlier we talked about how accessors are slower than direct field
-accesses, so this is an example of a certain language idiom resulting in an
-"invisible" performance hit.</p>
-
-<p>If you're using code like this in a performance hotspot, you can avoid the
-overhead by declaring fields and methods accessed by inner classes to have
-package access, rather than private access. Unfortunately this means the fields
-can be accessed directly by other classes in the same package, so you shouldn't
-use this in public API.</p>
-
-<a name="avoidfloat" id="avoidfloat"></a>
-<h2>Use Floating-Point Judiciously</h2>
-
-<p>As a rule of thumb, floating-point is about 2x slower than integer on
-Android devices. This is true on a FPU-less, JIT-less G1 and a Nexus One with
-an FPU and the JIT. (Of course, absolute speed difference between those two
-devices is about 10x for arithmetic operations.)</p>
-
-<p>In speed terms, there's no difference between <code>float</code> and
-<code>double</code> on the more modern hardware. Space-wise, <code>double</code>
-is 2x larger. As with desktop machines, assuming space isn't an issue, you
-should prefer <code>double</code> to <code>float</code>.</p>
-
-<p>Also, even for integers, some chips have hardware multiply but lack
-hardware divide. In such cases, integer division and modulus operations are
-performed in software &mdash; something to think about if you're designing a
-hash table or doing lots of math.</p>
-
-<a name="library" id="library"></a>
-<h2>Know And Use The Libraries</h2>
-
-<p>In addition to all the usual reasons to prefer library code over rolling
-your own, bear in mind that the system is at liberty to replace calls
-to library methods with hand-coded assembler, which may be better than the
-best code the JIT can produce for the equivalent Java. The typical example
-here is <code>String.indexOf</code> and friends, which Dalvik replaces with
-an inlined intrinsic. Similarly, the <code>System.arraycopy</code> method
-is about 9x faster than a hand-coded loop on a Nexus One with the JIT.</p>
-
-<p>(See also <em>Effective Java</em> item 47.)</p>
-
-<a name="native_methods" id="native_methods"></a>
-<h2>Use Native Methods Judiciously</h2>
-
-<p>Native code isn't necessarily more efficient than Java. For one thing,
-there's a cost associated with the Java-native transition, and the JIT can't
-optimize across these boundaries. If you're allocating native resources (memory
-on the native heap, file descriptors, or whatever), it can be significantly
-more difficult to arrange timely collection of these resources. You also
-need to compile your code for each architecture you wish to run on (rather
-than rely on it having a JIT). You may even have to compile multiple versions
-for what you consider the same architecture: native code compiled for the ARM
-processor in the G1 can't take full advantage of the ARM in the Nexus One, and
-code compiled for the ARM in the Nexus One won't run on the ARM in the G1.</p>
-
-<p>Native code is primarily useful when you have an existing native codebase
-that you want to port to Android, not for "speeding up" parts of a Java app.</p>
-
-<p>If you do need to use native code, you should read our
-<a href="{@docRoot}guide/practices/jni.html">JNI Tips</a>.</p>
-
-<p>(See also <em>Effective Java</em> item 54.)</p>
-
-<a name="closing_notes" id="closing_notes"></a>
-<h2>Closing Notes</h2>
-
-<p>One last thing: always measure. Before you start optimizing, make sure you
-have a problem. Make sure you can accurately measure your existing performance,
-or you won't be able to measure the benefit of the alternatives you try.</p>
-
-<p>Every claim made in this document is backed up by a benchmark. The source
-to these benchmarks can be found in the <a href="http://code.google.com/p/dalvik/source/browse/#svn/trunk/benchmarks">code.google.com "dalvik" project</a>.</p>
-
-<p>The benchmarks are built with the
-<a href="http://code.google.com/p/caliper/">Caliper</a> microbenchmarking
-framework for Java. Microbenchmarks are hard to get right, so Caliper goes out
-of its way to do the hard work for you, and even detect some cases where you're
-not measuring what you think you're measuring (because, say, the VM has
-managed to optimize all your code away). We highly recommend you use Caliper
-to run your own microbenchmarks.</p>
-
-<p>You may also find
-<a href="{@docRoot}tools/debugging/debugging-tracing.html">Traceview</a> useful
-for profiling, but it's important to realize that it currently disables the JIT,
-which may cause it to misattribute time to code that the JIT may be able to win
-back. It's especially important after making changes suggested by Traceview
-data to ensure that the resulting code actually runs faster when run without
-Traceview.

-<p><strong>Figure 1.</strong> An ANR dialog displayed to the user.</p>
-</div>
-
-<p>It's possible to write code that wins every performance test in the world,
-but still sends users in a fiery rage when they try to use the application.
-These are the applications that aren't <em>responsive</em> enough &mdash; the
-ones that feel sluggish, hang or freeze for significant periods, or take too
-long to process input. </p>
-
-<p>In Android, the system guards against applications that are insufficiently
-responsive for a period of time by displaying a dialog to the user, called the
-Application Not Responding (ANR) dialog, shown at right in Figure 1. The user
-can choose to let the application continue, but the user won't appreciate having
-to act on this dialog every time he or she uses your application. It's critical
-to design responsiveness into your application, so that the system never has
-cause to display an ANR dialog to the user. </p>
-
-<p>Generally, the system displays an ANR if an application cannot respond to
-user input. For example, if an  application blocks on some I/O operation
-(frequently a network access), then the main application thread won't be able to
-process incoming user input events. After a time, the system concludes that the
-application is frozen, and displays the ANR to give the user the option to kill
-it. </p>
-
-<p>Similarly, if your application spends too much time building an elaborate in-memory
-structure, or perhaps computing the next move in a game, the system will 
-conclude that your application has hung. It's always important to make
-sure these computations are efficient using the techniques above, but even the
-most efficient code still takes time to run.</p>
-
-<p>In both of these cases, the recommended approach is to create a child thread and do
-most of your work there. This keeps the main thread (which drives the user
-interface event loop) running and prevents the system from concluding that your code
-has frozen. Since such threading usually is accomplished at the class
-level, you can think of responsiveness as a <em>class</em> problem. (Compare
-this with basic performance, which was described above as a <em>method</em>-level
-concern.)</p>
-
-<p>This document describes how the Android system determines whether an
-application is not responding and provides guidelines for ensuring that your
-application stays responsive. </p>
-
-<h2 id="anr">What Triggers ANR?</h2>
-
-<p>In Android, application responsiveness is monitored by the Activity Manager
-and Window Manager system services. Android will display the ANR dialog
-for a particular application when it detects one of the following
-conditions:</p>
-<ul>  
-    <li>No response to an input event (e.g. key press, screen touch) 
-    within 5 seconds</li>
-    <li>A {@link android.content.BroadcastReceiver BroadcastReceiver} 
-    hasn't finished executing within 10 seconds</li>
-</ul>
-
-<h2 id="avoiding">How to Avoid ANR</h2>
-
-<p>Given the above definition for ANR, let's examine why this can occur in
-Android applications and how best to structure your application to avoid ANR.</p>
-
-<p>Android applications normally run entirely on a single (i.e. main) thread.
-This means that anything your application is doing in the main thread that
-takes a long time to complete can trigger the ANR dialog because your
-application is not giving itself a chance to handle the input event or Intent
-broadcast.</p>
-
-<p>Therefore any method that runs in the main thread should do as little work
-as possible. In particular, Activities should do as little as possible to set
-up in key life-cycle methods such as <code>onCreate()</code> and
-<code>onResume()</code>. Potentially long running operations such as network
-or database operations, or computationally expensive calculations such as
-resizing bitmaps should be done in a child thread (or in the case of databases
-operations, via an asynchronous request). However, this does not mean that
-your main thread should block while waiting for the child thread to
-complete &mdash; nor should you call <code>Thread.wait()</code> or
-<code>Thread.sleep()</code>. Instead of blocking while waiting for a child
-thread to complete, your main thread should provide a {@link
-android.os.Handler Handler} for child threads to post back to upon completion.
-Designing your application in this way will allow your main thread to remain
-responsive to input and thus avoid ANR dialogs caused by the 5 second input
-event timeout. These same practices should be followed for any other threads
-that display UI, as they are also subject to the same timeouts.</p>
-
-<p>You can use {@link android.os.StrictMode} to help find potentially
-long running operations such as network or database operations that
-you might accidentally be doing your main thread.</p>
-
-<p>The specific constraint on IntentReceiver execution time emphasizes what
-they were meant to do: small, discrete amounts of work in the background such
-as saving a setting or registering a Notification. So as with other methods
-called in the main thread, applications should avoid potentially long-running
-operations or calculations in BroadcastReceivers. But instead of doing intensive
-tasks via child threads (as the life of a BroadcastReceiver is short), your
-application should start a {@link android.app.Service Service} if a
-potentially long running action needs to be taken in response to an Intent
-broadcast. As a side note, you should also avoid starting an Activity from an
-Intent Receiver, as it will spawn a new screen that will steal focus from
-whatever application the user is currently has running. If your application
-has something to show the user in response to an Intent broadcast, it should
-do so using the {@link android.app.NotificationManager Notification
-Manager}.</p>
-
-<h2 id="reinforcing">Reinforcing Responsiveness</h2>
-
-<p>Generally, 100 to 200ms is the threshold beyond which users will perceive
-lag (or lack of "snappiness," if you will) in an application. As such, here
-are some additional tips beyond what you should do to avoid ANR that will help
-make your application seem responsive to users.</p>
-
-<ul>
-    <li>If your application is doing work in the background in response to
-    user input, show that progress is being made ({@link
-    android.widget.ProgressBar ProgressBar} and {@link
-    android.app.ProgressDialog ProgressDialog} are useful for this).</li>
-    <li>For games specifically, do calculations for moves in a child
-    thread.</li>
-    <li>If your application has a time-consuming initial setup phase, consider
-    showing a splash screen or rendering the main view as quickly as possible
-    and filling in the information asynchronously. In either case, you should
-    indicate somehow that progress is being made, lest the user perceive that
-    the application is frozen.</li>

-<p>Android was designed so that most developers will be able to build
-applications using the default settings and not be confronted with difficult
-decisions about security.  Android also has a number of security features built
-into the operating system that significantly reduce the frequency and impact of
-application security issues.</p>
-
-<p>Some of the security features that help developers build secure applications
-include:
-<ul>
-<li>The Android Application Sandbox that isolates data and code execution on a
-per-application basis.</li>
-<li>Android application framework with robust implementations of common
-security functionality such as cryptography, permissions, and secure IPC.</li>
-<li>Technologies like ASLR, NX, ProPolice, safe_iop, OpenBSD dlmalloc, OpenBSD
-calloc, and Linux mmap_min_addr to mitigate risks associated with common memory
-management errors</li>
-<li>An encrypted filesystem that can be enabled to protect data on lost or
-stolen devices.</li>
-</ul></p>
-
-<p>Nevertheless, it is important for developers to be familiar with Android
-security best practices to make sure they take advantage of these capabilities
-and to reduce the likelihood of inadvertently introducing security issues that
-can affect their applications.</p>
-
-<p>This document is organized around common APIs and development techniques
-that can have security implications for your application and its users. As
-these best practices are constantly evolving, we recommend you check back
-occasionally throughout your application development process.</p>
-
-<a name="Dalvik"></a>
-<h2>Using Dalvik Code</h2>
-<p>Writing secure code that runs in virtual machines is a well-studied topic
-and many of the issues are not specific to Android.  Rather than attempting to
-rehash these topics, we’d recommend that you familiarize yourself with the
-existing literature. Two of the more popular resources are:
-<ul>
-<li><a href="http://www.securingjava.com/toc.html">
-http://www.securingjava.com/toc.html</a></li>
-<li><a
-href="https://www.owasp.org/index.php/Java_Security_Resources">
-https://www.owasp.org/index.php/Java_Security_Resources</a></li>
-</ul></p>
-
-<p>This document is focused on the areas which are Android specific and/or
-different from other environments.  For developers experienced with VM
-programming in other environments, there are two broad issues that may be
-different about writing apps for Android:
-<ul>
-<li>Some virtual machines, such as the JVM or .net runtime, act as a security
-boundary, isolating code from the underlying operating system capabilities.  On
-Android, the Dalvik VM is not a security boundary -- the application sandbox is
-implemented at the OS level, so Dalvik can interoperate with native code in the
-same application without any security constraints.</li>
-<li>Given the limited storage on mobile devices, it’s common for developers
-to want to build modular applications and use dynamic class loading.  When
-doing this consider both the source where you retrieve your application logic
-and where you store it locally. Do not use dynamic class loading from sources
-that are not verified, such as unsecured network sources or external storage,
-since that code can be modified to include malicious behavior.</li>
-</ul></p>
-
-<a name="Native"></a>
-<h2>Using Native Code</h2>
-
-<p>In general, we encourage developers to use the Android SDK for most
-application development, rather than using native code.   Applications built
-with native code are more complex, less portable, and more like to include
-common memory corruption errors such as buffer overflows.</p>
-
-<p>Android is built using the Linux kernel and being familiar with Linux
-development security best practices is especially useful if you are going to
-use native code. This document is too short to discuss all of those best
-practices, but one of the most popular resources is  “Secure Programming for
-Linux and Unix HOWTO”, available at <a
-href="http://www.dwheeler.com/secure-programs">
-http://www.dwheeler.com/secure-programs</a>.</p>
-
-<p>An important difference between Android and most Linux environments is the
-Application Sandbox.  On Android, all applications run in the Application
-Sandbox, including those written with native code.  At the most basic level, a
-good way to think about it for developers familiar with Linux is to know that
-every application is given a unique UID with very limited permissions. This is
-discussed in more detail in the <a
-href="http://source.android.com/tech/security/index.html">Android Security
-Overview</a> and you should be familiar with application permissions even if
-you are using native code.</p>
-
-<a name="Data"></a>
-<h2>Storing Data</h2>
-
-<h3>Using internal files</h3>
-
-<p>By default, files created on <a
-href="{@docRoot}guide/topics/data/data-storage.html#filesInternal">internal
-storage</a> are only accessible to the application that created the file. This
-protection is implemented by Android and is sufficient for most
-applications.</p>
-
-<p>Use of <a
-href="{@docRoot}reference/android/content/Context.html#MODE_WORLD_WRITEABLE">
-world writable</a> or <a
-href="{@docRoot}reference/android/content/Context.html#MODE_WORLD_READABLE">world
-readable</a> files for IPC is discouraged because it does not provide
-the ability to limit data access to particular applications, nor does it
-provide any control on data format. As an alternative, you might consider using
-a ContentProvider which provides read and write permissions, and can make
-dynamic permission grants on a case-by-case basis.</p>
-
-<p>To provide additional protection for sensitive data, some applications
-choose to encrypt local files using a key that is not accessible to the
-application. (For example, a key can be placed in a {@link java.security.KeyStore}
-and protected with a user password that is not stored on the device).  While this
-does not protect data from a root compromise that can monitor the user
-inputting the password,  it can provide protection for a lost device without <a
-href="http://source.android.com/tech/encryption/index.html">file system
-encryption</a>.</p>
-
-<h3>Using external storage</h3>
-
-<p>Files created on <a
-href="{@docRoot}guide/topics/data/data-storage.html#filesExternal">external
-storage</a>, such as SD Cards, are globally readable and writable.  Since
-external storage can be removed by the user and also modified by any
-application,  applications should not store sensitive information using
-external storage.</p>
-
-<p>As with data from any untrusted source, applications should perform input
-validation when handling data from external storage (see Input Validation
-section).  We strongly recommend that applications not store executables or
-class files on external storage prior to dynamic loading.  If an application
-does retrieve executable files from external storage they should be signed and
-cryptographically verified prior to dynamic loading.</p>
-
-<h3>Using content providers</h3>
-
-<p>ContentProviders provide a structured storage mechanism that can be limited
-to your own application, or exported to allow access by other applications. By
-default, a <code>
-<a href="{@docRoot}reference/android/content/ContentProvider.html">
-ContentProvider</a></code> is
-<a href="{@docRoot}guide/topics/manifest/provider-element.html#exported">exported
-</a> for use by other applications.  If you do not intend to provide other
-applications with access to your<code>
-<a href="{@docRoot}reference/android/content/ContentProvider.html">
-ContentProvider</a></code>, mark them as <code><a
-href="{@docRoot}guide/topics/manifest/provider-element.html#exported">
-android:exported=false</a></code> in the application manifest.</p>
-
-<p>When creating a <code>
-<a href="{@docRoot}reference/android/content/ContentProvider.html">ContentProvider
-</a></code> that will be exported for use by other applications, you can specify
-a single
-<a href="{@docRoot}guide/topics/manifest/provider-element.html#prmsn">permission
-</a> for reading and writing, or distinct permissions for reading and writing
-within the manifest. We recommend that you limit your permissions to those
-required to accomplish the task at hand. Keep in mind that it’s usually
-easier to add permissions later to expose new functionality than it is to take
-them away and break existing users.</p>
-
-<p>If you are using a <code>
-<a href="{@docRoot}reference/android/content/ContentProvider.html">
-ContentProvider</a></code> for sharing data between applications built by the
-same developer, it is preferable to use
-<a href="{@docRoot}guide/topics/manifest/permission-element.html#plevel">signature
-level permissions</a>.  Signature permissions do not require user confirmation,
-so they provide a better user experience and more controlled access to the
-<code>
-<a href="{@docRoot}reference/android/content/ContentProvider.html">
-ContentProvider</a></code>.</p>
-
-<p>ContentProviders can also provide more granular access by declaring the <a
-href="{@docRoot}guide/topics/manifest/provider-element.html#gprmsn">
-grantUriPermissions</a> element and using the <code><a
-href="{@docRoot}reference/android/content/Intent.html#FLAG_GRANT_READ_URI_PERMISSION">FLAG_GRANT_READ_URI_PERMISSION</a></code>
-and <code><a
-href="{@docRoot}reference/android/content/Intent.html#FLAG_GRANT_WRITE_URI_PERMISSION">FLAG_GRANT_WRITE_URI_PERMISSION</a></code>
-flags in the Intent object
-that activates the component.  The scope of these permissions can be further
-limited by the <code><a
-href="{@docRoot}guide/topics/manifest/grant-uri-permission-element.html">
-grant-uri-permission element</a></code>.</p>
-
-<p>When accessing a <code>
-<a href="{@docRoot}reference/android/content/ContentProvider.html">
-ContentProvider</a></code>, use parameterized query methods such as <code>
-<a href="{@docRoot}reference/android/content/ContentProvider.html#query(android.net.Uri,%20java.lang.String[],%20java.lang.String,%20java.lang.String[],%20java.lang.String)">query()</a></code>, <code><a
-href="{@docRoot}reference/android/content/ContentProvider.html#update(android.net.Uri,%20android.content.ContentValues,%20java.lang.String,%20java.lang.String[])">update()</a></code>, and <code><a
-href="{@docRoot}reference/android/content/ContentProvider.html#delete(android.net.Uri,%20java.lang.String,%20java.lang.String[])">delete()</a></code> to avoid
-potential <a href="http://en.wikipedia.org/wiki/SQL_injection">SQL
-Injection</a> from untrusted data. Note that using parameterized methods is not
-sufficient if the <code>selection</code> is built by concatenating user data
-prior to submitting it to the method.</p>
-
-<p>Do not have a false sense of security about the write permission.  Consider
-that the write permission allows SQL statements which make it possible for some
-data to be confirmed using creative <code>WHERE</code> clauses and parsing the
-results. For example, an attacker might probe for presence of a specific phone
-number in a call-log by modifying a row only if that phone number already
-exists. If the content provider data has predictable structure, the write
-permission may be equivalent to providing both reading and writing.</p>
-
-<a name="IPC"></a>
-<h2>Using Interprocess Communication (IPC)</h2>
-
-<p>Some Android applications attempt to implement IPC using traditional Linux
-techniques such as network sockets and shared files.  We strongly encourage the
-use of Android system functionality for IPC such as Intents, Binders, Services,
-and Receivers.  The Android IPC mechanisms allow you to verify the identity of
-the application connecting to your IPC and set security policy for each IPC
-mechanism.</p>
-
-<p>Many of the security elements are shared across IPC mechanisms. <a
-href="{@docRoot}reference/android/content/BroadcastReceiver.html">
-Broadcast Receivers</a>, <a
-href="{@docRoot}reference/android/R.styleable.html#AndroidManifestActivity">
-Activities</a>, and <a
-href="{@docRoot}reference/android/R.styleable.html#AndroidManifestService">
-Services</a> are all declared in the application manifest.  If your IPC mechanism is
-not intended for use by other applications, set the <a
-href="{@docRoot}guide/topics/manifest/service-element.html#exported">{@code android:exported}</a>
-property to false.  This is useful for applications that consist of multiple processes
-within the same UID, or if you decide late in development that you do not
-actually want to expose functionality as IPC but you don’t want to rewrite
-the code.</p>
-
-<p>If your IPC is intended to be accessible to other applications, you can
-apply a security policy by using the <a
-href="{@docRoot}reference/android/R.styleable.html#AndroidManifestPermission">
-Permission</a> tag. If IPC is between applications built by the same developer,
-it is preferable to use <a
-href="{@docRoot}guide/topics/manifest/permission-element.html#plevel">signature
-level permissions</a>.  Signature permissions do not require user confirmation,
-so they provide a better user experience and more controlled access to the IPC
-mechanism.</p>
-
-<p>One area that can introduce confusion is the use of intent filters. Note
-that Intent filters should not be considered a security feature -- components
-can be invoked directly and may not have data that would conform to the intent
-filter. You should perform input validation within your intent receiver to
-confirm that it is properly formatted for the invoked receiver, service, or
-activity.</p>
-
-<h3>Using intents</h3>
-
-<p>Intents are the preferred mechanism for asynchronous IPC in Android.
-Depending on your application requirements, you might use <code><a
-href="{@docRoot}reference/android/content/Context.html#sendBroadcast(android.content.Intent)">sendBroadcast()</a></code>, 
-<code><a
-href="{@docRoot}reference/android/content/Context.html#sendOrderedBroadcast(android.content.Intent,%20java.lang.String)">sendOrderedBroadcast()</a></code>,
-or direct an intent to a specific application component.</p>
-
-<p>Note that ordered broadcasts can be “consumed” by a recipient, so they
-may not be delivered to all applications.  If you are sending an Intent where
-delivery to a specific receiver is required, the intent must be delivered
-directly to the receiver.</p>
-
-<p>Senders of an intent can verify that the recipient has a permission
-specifying a non-Null Permission upon sending.  Only applications with that
-Permission will receive the intent.  If data within a broadcast intent may be
-sensitive, you should consider applying a permission to make sure that
-malicious applications cannot register to receive those messages without
-appropriate permissions.  In those circumstances, you may also consider
-invoking the receiver directly, rather than raising a broadcast.</p>
-
-<h3>Using binder and AIDL interfaces</h3>
-
-<p><a href="{@docRoot}reference/android/os/Binder.html">Binders</a> are the
-preferred mechanism for RPC-style IPC in Android. They provide a well-defined
-interface that enables mutual authentication of the endpoints, if required.</p>
-
-<p>We strongly encourage designing interfaces in a manner that does not require
-interface specific permission checks. Binders are not declared within the
-application manifest, and therefore you cannot apply declarative permissions
-directly to a Binder.  Binders generally inherit permissions declared in the
-application manifest for the Service or Activity within which they are
-implemented.  If you are creating an interface that requires authentication
-and/or access controls on a specific binder interface, those controls must be
-explicitly added as code in the interface.</p>
-
-<p>If providing an interface that does require access controls, use <code><a
-href="{@docRoot}reference/android/content/Context.html#checkCallingPermission(java.lang.String)">checkCallingPermission()</a></code>
-to verify whether the
-caller of the Binder has a required permission. This is especially important
-before accessing a Service on behalf of the caller, as the identify of your
-application is passed to other interfaces.  If invoking an interface provided
-by a Service, the <code><a
-href="{@docRoot}reference/android/content/Context.html#bindService(android.content.Intent,%20android.content.ServiceConnection,%20int)">bindService()</a></code>
- invocation may fail if you do not have permission to access the given Service.
- If calling an interface provided locally by your own application, it may be
-useful to use the <code><a
-href="{@docRoot}reference/android/os/Binder.html#clearCallingIdentity()">
-clearCallingIdentity()</a></code> to satisfy internal security checks.</p>
-
-<h3>Using broadcast receivers</h3>
-
-<p>Broadcast receivers are used to handle asynchronous requests initiated via
-an intent.</p>
-
-<p>By default, receivers are exported and can be invoked by any other
-application. If your <code><a
-href="{@docRoot}reference/android/content/BroadcastReceiver.html">
-BroadcastReceivers</a></code> is intended for use by other applications, you
-may want to apply security permissions to receivers using the <code><a
-href="{@docRoot}guide/topics/manifest/receiver-element.html">
-&lt;receiver&gt;</a></code> element within the application manifest.  This will
-prevent applications without appropriate permissions from sending an intent to
-the <code><a
-href="{@docRoot}reference/android/content/BroadcastReceiver.html">
-BroadcastReceivers</a></code>.</p>
-
-<h3>Using Services</h3>
-
-<p>Services are often used to supply functionality for other applications to
-use. Each service class must have a corresponding <service> declaration in its
-package's AndroidManifest.xml.</p>
-
-<p>By default, Services are exported and can be invoked by any other
-application.  Services can be protected using the <a
-href="{@docRoot}guide/topics/manifest/service-element.html#prmsn">{@code android:permission}</a>
-attribute
-within the manifest’s <code><a
-href="{@docRoot}guide/topics/manifest/service-element.html">
-&lt;service&gt;</a></code> tag. By doing so, other applications will need to declare
-a corresponding <code><a
-href="{@docRoot}guide/topics/manifest/uses-permission-element.html">&lt;uses-permission&gt;</a>
-</code> element in their own manifest to be
-able to start, stop, or bind to the service.</p>
-
-<p>A Service can protect individual IPC calls into it with permissions, by
-calling <code><a
-href="{@docRoot}reference/android/content/Context.html#checkCallingPermission(java.lang.String)">checkCallingPermission()</a></code>
-before executing
-the implementation of that call.  We generally recommend using the
-declarative permissions in the manifest, since those are less prone to
-oversight.</p>
-
-<h3>Using Activities</h3>
-
-<p>Activities are most often used for providing the core user-facing
-functionality of an application. By default, Activities are exported and
-invokable by other applications only if they have an intent filter or binder
-declared.  In general, we recommend that you specifically declare a Receiver or
-Service to handle IPC, since this modular approach reduces the risk of exposing
-functionality that is not intended for use by other applications.</p>
-
-<p>If you do expose an Activity for purposes of IPC, the  <code><a
-href="{@docRoot}guide/topics/manifest/activity-element.html#prmsn">android:permission</a></code>
-attribute in the  <code><a
-href="{@docRoot}guide/topics/manifest/activity-element.html">
-&lt;activity&gt;</a></code> declaration in the application manifest can be used to
-restrict access to only those applications which have the stated
-permissions.</p>
-
-<a name="Permissions"></a>
-<h2>Using Permissions</h2>
-
-<h3>Requesting Permissions</h3>
-
-<p>We recommend minimizing the number of permissions requested by an
-application. Not having access to sensitive permissions reduces the risk of
-inadvertently misusing those permissions, can improve user adoption, and makes
-applications less attractive targets for attackers.</p>
-
-<p>If it is possible to design your application in a way that does not require
-a permission, that is preferable.  For example, rather than requesting access
-to device information to create an identifier, create a <a
-href="{@docRoot}reference/java/util/UUID.html">GUID</a> for your application.
-(This specific example is also discussed in Handling User Data) Or, rather than
-using external storage, store data in your application directory.</p>
-
-<p>If a permission is not required, do not request it.  This sounds simple, but
-there has been quite a bit of research into the frequency of over-requesting
-permissions. If you’re interested in the subject you might start with this
-research paper published by U.C. Berkeley: <a
-href="http://www.eecs.berkeley.edu/Pubs/TechRpts/2011/EECS-2011-48.pdf">
-http://www.eecs.berkeley.edu/Pubs/TechRpts/2011/EECS-2011-48.pdf</a></p>
-
-<p>In addition to requesting permissions, your application can use <a
-href="{@docRoot}guide/topics/manifest/permission-element.html">permissions</a>
-to protect IPC that is security sensitive and will be exposed to other
-applications -- such as a <code><a
-href="{@docRoot}reference/android/content/ContentProvider.html">
-ContentProvider</a></code>.  In general, we recommend using access controls
-other than user confirmed permissions where possible since permissions can
-be confusing for users. For example, consider using the <a
-href="{@docRoot}guide/topics/manifest/permission-element.html#plevel">signature
-protection level</a> on permissions for IPC communication between applications
-provided by a single developer.</p>
-
-<p>Do not cause permission re-delegation.  This occurs when an app exposes data
-over IPC that is only available because it has a specific permission, but does
-not require that permission of any clients of it’s IPC interface. More
-details on the potential impacts, and frequency of this type of problem is
-provided in this research paper published at USENIX: <a
-href="http://www.cs.berkeley.edu/~afelt/felt_usenixsec2011.pdf">http://www.cs.be
-rkeley.edu/~afelt/felt_usenixsec2011.pdf</a></p>
-
-<h3>Creating Permissions</h3>
-
-<p>Generally, you should strive to create as few permissions as possible while
-satisfying your security requirements.  Creating a new permission is relatively
-uncommon for most applications, since <a
-href="{@docRoot}reference/android/Manifest.permission.html">system-defined
-permissions</a> cover many situations.  Where appropriate,
-perform access checks using existing permissions.</p>
-
-<p>If you must create a new permission, consider whether you can accomplish
-your task with a Signature permission.  Signature permissions are transparent
-to the user and only allow access by applications signed by the same developer
-as application performing the permission check.  If you create a Dangerous
-permission, then the user needs to decide whether to install the application.
-This can be confusing for other developers, as well as for users.</p>
-
-<p>If you create a Dangerous permission, there are a number of complexities
-that you need to consider.
-<ul>
-<li>The permission must have a string that concisely expresses to a user the
-security decision they will be required to make.</li>
-<li>The permission string must be localized to many different languages.</li>
-<li>Uses may choose not to install an application because a permission is
-confusing or perceived as risky.</li>
-<li>Applications may request the permission when the creator of the permission
-has not been installed.</li>
-</ul></p>
-
-<p>Each of these poses a significant non-technical challenge for an application
-developer, which is why we discourage the use of Dangerous permission.</p>
-
-<a name="Networking"></a>
-<h2>Using Networking</h2>
-
-<h3>Using IP Networking</h3>
-
-<p>Networking on Android is not significantly different from Linux
-environments.  The key consideration is making sure that appropriate protocols
-are used for sensitive data, such as <a
-href="{@docRoot}reference/javax/net/ssl/HttpsURLConnection.html">HTTPS</a> for
-web traffic.   We prefer use of HTTPS over HTTP anywhere that HTTPS is
-supported on the server, since mobile devices frequently connect on networks
-that are not secured, such as public WiFi hotspots.</p>
-
-<p>Authenticated, encrypted socket-level communication can be easily
-implemented using the <code><a
-href="{@docRoot}reference/javax/net/ssl/SSLSocket.html">SSLSocket</a></code>
-class.  Given the frequency with which Android devices connect to unsecured
-wireless networks using WiFi, the use of secure networking is strongly
-encouraged for all applications.</p>
-
-<p>We have seen some applications use <a
-href="http://en.wikipedia.org/wiki/Localhost">localhost</a> network ports for
-handling sensitive IPC.  We discourage this approach since these interfaces are
-accessible by other applications on the device.  Instead, use an Android IPC
-mechanism where authentication is possible such as a Service and Binder.  (Even
-worse than using loopback is to bind to INADDR_ANY since then your application
-may receive requests from anywhere.  We’ve seen that, too.)</p>
-
-<p>Also, one common issue that warrants repeating is to make sure that you do
-not trust data downloaded from HTTP or other insecure protocols.  This includes
-validation of input in <code><a
-href="{@docRoot}reference/android/webkit/WebView.html">WebView</a></code> and
-any responses to intents issued against HTTP.</p>
-
-<h3>Using Telephony Networking</h3>
-
-<p>SMS is the telephony protocol most frequently used by Android developers.
-Developers should keep in mind that this protocol was primarily designed for
-user-to-user communication and is not well-suited for some application
-purposes. Due to the limitations of SMS, we strongly recommend the use of <a
-href="http://code.google.com/android/c2dm/">C2DM</a> and IP networking for
-sending data messages to devices.</p>
-
-<p>Many developers do not realize that SMS is not encrypted or strongly
-authenticated on the network or on the device.  In particular, any SMS receiver
-should expect that a malicious user may have sent the SMS to your application
--- do not rely on unauthenticated SMS data to perform sensitive commands.
-Also, you should be aware that SMS may be subject to spoofing and/or
-interception on the network.  On the Android-powered device itself, SMS
-messages are transmitted as Broadcast intents, so they may be read or captured
-by other applications that have the READ_SMS permission.</p>
-
-<a name="DynamicCode"></a>
-<h2>Dynamically Loading Code</h2>
-
-<p>We strongly discourage loading code from outside of the application APK.
-Doing so significantly increases the likelihood of application compromise due
-to code injection or code tampering.  It also adds complexity around version
-management and application testing.  Finally, it can make it impossible to
-verify the behavior of an application, so it may be prohibited in some
-environments.</p>
-
-<p>If your application does dynamically load code, the most important thing to
-keep in mind about dynamically loaded code is that it runs with the same
-security permissions as the application APK.  The user made a decision to
-install your application based on your identity, and they are expecting that
-you provide any code run within the application, including code that is
-dynamically loaded.</p>
-
-<p>The major security risk associated with dynamically loading code is that the
-code needs to come from a verifiable source. If the modules are included
-directly within your APK, then they cannot be modified by other applications.
-This is true whether the code is a native library or a class being loaded using
-<a href="{@docRoot}reference/dalvik/system/DexClassLoader.html">
-<code>DexClassLoader</code></a>.  We have seen many instances of applications
-attempting to load code from insecure locations, such as downloaded from the
-network over unencrypted protocols or from world writable locations such as
-external storage. These locations could allow someone on the network to modify
-the content in transit, or another application on a users device to modify the
-content, respectively.</p>
-
-
-<h3>Using WebView</h3>
-
-<p>Since WebView consumes web content that can include HTML and JavaScript,
-improper use can introduce common web security issues such as <a
-href="http://en.wikipedia.org/wiki/Cross_site_scripting">cross-site-scripting</a
-> (JavaScript injection).  Android includes a number of mechanisms to reduce
-the scope of these potential issues by limiting the capability of WebView to
-the minimum functionality required by your application.</p>
-
-<p>If your application does not directly use JavaScript within a <code><a
-href="{@docRoot}reference/android/webkit/WebView.html">WebView</a></code>, do
-not call
-<a href="{@docRoot}reference/android/webkit/WebSettings.html#setJavaScriptEnabled(boolean)">
-<code>setJavaScriptEnabled()</code></a>. We have seen this method invoked
-in sample code that might be repurposed in production application -- so
-remove it if necessary. By default, <code><a
-href="{@docRoot}reference/android/webkit/WebView.html">WebView</a></code> does
-not execute JavaScript so cross-site-scripting is not possible.</p>
-
-<p>Use <code><a
-href="{@docRoot}reference/android/webkit/WebView.html#addJavascriptInterface(java.lang.Object,%20java.lang.String)">addJavaScriptInterface()</a></code> with
-particular care because it allows JavaScript to invoke operations that are
-normally reserved for Android applications.  Only expose <code><a
-href="{@docRoot}reference/android/webkit/WebView.html#addJavascriptInterface(java.lang.Object,%20java.lang.String)">addJavaScriptInterface()</a></code> to
-sources from which all input is trustworthy.  If untrusted input is allowed,
-untrusted JavaScript may be able to invoke Android methods.  In general, we
-recommend only exposing <code><a
-href="{@docRoot}reference/android/webkit/WebView.html#addJavascriptInterface(java.lang.Object,%20java.lang.String)">addJavaScriptInterface()</a></code> to
-JavaScript that is contained within your application APK.</p>
-
-<p>Do not trust information downloaded over HTTP, use HTTPS instead.  Even if
-you are connecting only to a single website that you trust or control, HTTP is
-subject to <a
-href="http://en.wikipedia.org/wiki/Man-in-the-middle_attack">MiTM</a> attacks
-and interception of data.  Sensitive capabilities using <code><a
-href="{@docRoot}reference/android/webkit/WebView.html#addJavascriptInterface(java.lang.Object,%20java.lang.String)">addJavaScriptInterface()</a></code> should
-not ever be exposed to unverified script downloaded over HTTP. Note that even
-with the use of HTTPS,
-<code><a
-href="{@docRoot}reference/android/webkit/WebView.html#addJavascriptInterface(java.lang.Object,%20java.lang.String)">addJavaScriptInterface()</a></code>
-increases the attack surface of your application to include the server
-infrastructure and all CAs trusted by the Android-powered device.</p>
-
-<p>If your application accesses sensitive data with a <code><a
-href="{@docRoot}reference/android/webkit/WebView.html">WebView</a></code>, you
-may want to use the <code><a
-href="{@docRoot}reference/android/webkit/WebView.html#clearCache(boolean)">
-clearCache()</a></code> method to delete any files stored locally. Server side
-headers like no-cache can also be used to indicate that an application should
-not cache particular content.</p>
-
-<a name="Input"></a>
-<h2>Performing Input Validation</h2>
-
-<p>Insufficient input validation is one of the most common security problems
-affecting applications, regardless of what platform they run on. Android does
-have platform-level countermeasures that reduce the exposure of applications to
-input validation issues, you should use those features where possible. Also
-note that selection of type-safe languages tends to reduce the likelihood of
-input validation issues.  We strongly recommend building your applications with
-the Android SDK.</p>
-
-<p>If you are using native code, then any data read from files, received over
-the network, or received from an IPC has the potential to introduce a security
-issue.  The most common problems are <a
-href="http://en.wikipedia.org/wiki/Buffer_overflow">buffer overflows</a>, <a
-href="http://en.wikipedia.org/wiki/Double_free#Use_after_free">use after
-free</a>, and <a
-href="http://en.wikipedia.org/wiki/Off-by-one_error">off-by-one errors</a>.
-Android provides a number of technologies like ASLR and DEP that reduce the
-exploitability of these errors, but they do not solve the underlying problem.
-These can be prevented by careful handling of pointers and managing of
-buffers.</p>
-
-<p>Dynamic, string based languages such as JavaScript and SQL are also subject
-to input validation problems due to escape characters and <a
-href="http://en.wikipedia.org/wiki/Code_injection">script injection</a>.</p>
-
-<p>If you are using data within queries that are submitted to SQL Database or a
-Content Provider, SQL Injection may be an issue.  The best defense is to use
-parameterized queries, as is discussed in the ContentProviders section.
-Limiting permissions to read-only or write-only can also reduce the potential
-for harm related to SQL Injection.</p>
-
-<p>If you are using <code><a
-href="{@docRoot}reference/android/webkit/WebView.html">WebView</a></code>, then
-you must consider the possibility of XSS.  If your application does not
-directly use JavaScript within a <code><a
-href="{@docRoot}reference/android/webkit/WebView.html">WebView</a></code>, do
-not call setJavaScriptEnabled() and XSS is no longer possible. If you must
-enable JavaScript then the WebView section provides other security best
-practices.</p>
-
-<p>If you cannot use the security features above, we strongly recommend the use
-of well-structured data formats and verifying that the data conforms to the
-expected format. While blacklisting of characters or character-replacement can
-be an effective strategy, these techniques are error-prone in practice and
-should be avoided when possible.</p>
-
-<a name="UserData"></a>
-<h2>Handling User Data</h2>
-
-<p>In general, the best approach is to minimize use of APIs that access
-sensitive or personal user data. If you have access to data and can avoid
-storing or transmitting the information, do not store or transmit the data.
-Finally, consider if there is a way that your application logic can be
-implemented using a hash or non-reversible form of the data.  For example, your
-application might use the hash of an an email address as a primary key, to
-avoid transmitting or storing the email address.  This reduces the chances of
-inadvertently exposing data, and it also reduces the chance of attackers
-attempting to exploit your application.</p>
-
-<p>If your application accesses personal information such as passwords or
-usernames, keep in mind that some jurisdictions may require you to provide a
-privacy policy explaining your use and storage of that data.  So following the
-security best practice of minimizing access to user data may also simplify
-compliance.</p>
-
-<p>You should also consider whether your application might be inadvertently
-exposing personal information to other parties such as third-party components
-for advertising or third-party services used by your application. If you don't
-know why a component or service requires a personal information, don’t
-provide it.  In general, reducing the access to personal information by your
-application will reduce the potential for problems in this area.</p>
-
-<p>If access to sensitive data is required, evaluate whether that information
-must be transmitted to a server, or whether the operation can be performed on
-the client.  Consider running any code using sensitive data on the client to
-avoid transmitting user data.</p>
-
-<p>Also, make sure that you do not inadvertently expose user data to other
-application on the device through overly permissive IPC, world writable files,
-or network sockets. This is a special case of permission redelegation,
-discussed in the Requesting Permissions section.</p>
-
-<p>If a GUID is required, create a large, unique number and store it.  Do not
-use phone identifiers such as the phone number or IMEI which may be associated
-with personal information.  This topic is discussed in more detail in the <a
-href="http://android-developers.blogspot.com/2011/03/identifying-app-installations.html">Android Developer Blog</a>.</p>
-
-<p>Application developers should be careful writing to on-device logs.
-In Android, logs are a shared resource, and are available
-to an application with the
-<a href="{@docRoot}reference/android/Manifest.permission.html#READ_LOGS">
-<code>READ_LOGS</code></a> permission. Even though the phone log data
-is temporary and erased on reboot, inappropriate logging of user information
-could inadvertently leak user data to other applications.</p>
-
-
-<h3>Handling Credentials</h3>
-
-<p>In general, we recommend minimizing the frequency of asking for user
-credentials -- to make phishing attacks more conspicuous, and less likely to be
-successful.  Instead use an authorization token and refresh it.</p>
-
-<p>Where possible, username and password should not be stored on the device.
-Instead, perform initial authentication using the username and password
-supplied by the user, and then use a short-lived, service-specific
-authorization token.</p>
-
-<p>Services that will be accessible to multiple applications should be accessed
-using <code>
-<a href="{@docRoot}reference/android/accounts/AccountManager.html">
-AccountManager</a></code>. If possible, use the <code><a
-href="{@docRoot}reference/android/accounts/AccountManager.html">
-AccountManager</a></code> class to invoke a cloud-based service and do not store
-passwords on the device.</p>
-
-<p>After using <code><a
-href="{@docRoot}reference/android/accounts/AccountManager.html">
-AccountManager</a></code> to retrieve an Account, check the <code><a
-href="{@docRoot}reference/android/accounts/Account.html#CREATOR">CREATOR</a>
-</code> before passing in any credentials, so that you do not inadvertently pass
-credentials to the wrong application.</p>
-
-<p>If credentials are to be used only by applications that you create, then you
-can verify the application which accesses the <code><a
-href="{@docRoot}reference/android/accounts/AccountManager.html">
-AccountManager</a></code> using <code><a
-href="{@docRoot}reference/android/content/pm/PackageManager.html#checkSignatures(java.lang.String,%20java.lang.String)">checkSignature()</a></code>.
-Alternatively, if only one application will use the credential, you might use a
-{@link java.security.KeyStore} for
-storage.</p>
-
-<a name="Crypto"></a>
-<h2>Using Cryptography</h2>
-
-<p>In addition to providing data isolation, supporting full-filesystem
-encryption, and providing secure communications channels Android provides a
-wide array of algorithms for protecting data using cryptography.</p>
-
-<p>In general, try to use the highest level of pre-existing framework
-implementation that can  support your use case.  If you need to securely
-retrieve a file from a known location, a simple HTTPS URI may be adequate and
-require no knowledge of cryptography on your part.  If you need a secure
-tunnel, consider using
-<a href="{@docRoot}reference/javax/net/ssl/HttpsURLConnection.html">
-<code>HttpsURLConnection</code></a> or <code><a
-href="{@docRoot}reference/javax/net/ssl/SSLSocket.html">SSLSocket</a></code>,
-rather than writing your own protocol.</p>
-
-<p>If you do find yourself needing to implement your own protocol, we strongly
-recommend that you not implement your own cryptographic algorithms. Use
-existing cryptographic algorithms such as those in the implementation of AES or
-RSA provided in the <code><a
-href="{@docRoot}reference/javax/crypto/Cipher.html">Cipher</a></code> class.</p>
-
-<p>Use a secure random number generator (
-<a href="{@docRoot}reference/java/security/SecureRandom.html">
-<code>SecureRandom</code></a>) to initialize any cryptographic keys (<a
-href="{@docRoot}reference/javax/crypto/KeyGenerator.html">
-<code>KeyGenerator</code></a>). Use of a key that is not generated with a secure random
-number generator significantly weakens the strength of the algorithm, and may
-allow offline attacks.</p>
-
-<p>If you need to store a key for repeated use, use a mechanism like
-  {@link java.security.KeyStore} that
-provides a mechanism for long term storage and retrieval of cryptographic
-keys.</p>
-
-<h2>Conclusion</h2>
-
-<p>Android provides developers with the ability to design applications with a
-broad range of security requirements.  These best practices will help you make
-sure that your application takes advantage of the security benefits provided by
-the platform.</p>

+<p class="img-caption"><strong>Figure 1.</strong> An ANR dialog displayed to the user.</p>
+</div>
+
+<p>It's possible to write code that wins every performance test in the world,
+but still feels sluggish, hang or freeze for significant periods, or take too
+long to process input. The worst thing that can happen to your app's responsiveness
+is an "Application Not Responding" (ANR) dialog.</p>
+
+<p>In Android, the system guards against applications that are insufficiently
+responsive for a period of time by displaying a dialog that says your app has
+stopped responding, such as the dialog
+in Figure 1. At this point, your app has been unresponsive for a considerable
+period of time so the system offers the user an option to quit the app. It's critical
+to design responsiveness into your application so the system never displays
+an ANR dialog to the user. </p>
+
+<p>This document describes how the Android system determines whether an
+application is not responding and provides guidelines for ensuring that your
+application stays responsive. </p>
+
+
+<h2 id="anr">What Triggers ANR?</h2>
+
+<p>Generally, the system displays an ANR if an application cannot respond to
+user input. For example, if an  application blocks on some I/O operation
+(frequently a network access) on the UI thread so the system can't
+process incoming user input events. Or perhaps the app
+spends too much time building an elaborate in-memory
+structure or computing the next move in a game on the UI thread. It's always important to make
+sure these computations are efficient, but even the
+most efficient code still takes time to run.</p>
+
+<p>In any situation in which your app performs a potentially lengthy operation,
+<strong>you should not perform the work on the UI thread</strong>, but instead create a
+worker thread and do most of the work there. This keeps the UI thread (which drives the user
+interface event loop) running and prevents the system from concluding that your code
+has frozen. Because such threading usually is accomplished at the class
+level, you can think of responsiveness as a <em>class</em> problem. (Compare
+this with basic code performance, which is a <em>method</em>-level
+concern.)</p>
+
+<p>In Android, application responsiveness is monitored by the Activity Manager
+and Window Manager system services. Android will display the ANR dialog
+for a particular application when it detects one of the following
+conditions:</p>
+<ul>  
+    <li>No response to an input event (such as key press or screen touch events) 
+    within 5 seconds.</li>
+    <li>A {@link android.content.BroadcastReceiver BroadcastReceiver} 
+    hasn't finished executing within 10 seconds.</li>
+</ul>
+
+
+
+<h2 id="Avoiding">How to Avoid ANRs</h2>
+
+<p>Android applications normally run entirely on a single thread by default
+the "UI thread" or "main thread").
+This means anything your application is doing in the UI thread that
+takes a long time to complete can trigger the ANR dialog because your
+application is not giving itself a chance to handle the input event or intent
+broadcasts.</p>
+
+<p>Therefore, any method that runs in the UI thread should do as little work
+as possible on that thread. In particular, activities should do as little as possible to set
+up in key life-cycle methods such as {@link android.app.Activity#onCreate onCreate()}
+and {@link android.app.Activity#onResume onResume()}.
+Potentially long running operations such as network
+or database operations, or computationally expensive calculations such as
+resizing bitmaps should be done in a worker thread (or in the case of databases
+operations, via an asynchronous request).</p>
+
+<p>The most effecive way to create a worker thread for longer
+operations is with the {@link android.os.AsyncTask}
+class. Simply extend {@link android.os.AsyncTask} and implement the
+{@link android.os.AsyncTask#doInBackground doInBackground()} method to perform the work.
+To post progress changes to the user, you can call
+ {@link android.os.AsyncTask#publishProgress publishProgress()}, which invokes the
+ {@link android.os.AsyncTask#onProgressUpdate onProgressUpdate()} callback method. From your
+ implementation of {@link android.os.AsyncTask#onProgressUpdate onProgressUpdate()} (which
+ runs on the UI thread), you can notify the user. For example:</p>
+ 
+<pre>
+private class DownloadFilesTask extends AsyncTask&lt;URL, Integer, Long> {
+    // Do the long-running work in here
+    protected Long doInBackground(URL... urls) {
+        int count = urls.length;
+        long totalSize = 0;
+        for (int i = 0; i &lt; count; i++) {
+            totalSize += Downloader.downloadFile(urls[i]);
+            publishProgress((int) ((i / (float) count) * 100));
+            // Escape early if cancel() is called
+            if (isCancelled()) break;
+        }
+        return totalSize;
+    }
+
+    // This is called each time you call publishProgress()
+    protected void onProgressUpdate(Integer... progress) {
+        setProgressPercent(progress[0]);
+    }
+
+    // This is called when doInBackground() is finished
+    protected void onPostExecute(Long result) {
+        showNotification("Downloaded " + result + " bytes");
+    }
+}
+</pre>
+ 
+ <p>To execute this worker thread, simply create an instance and
+ call {@link android.os.AsyncTask#execute execute()}:</p>
+ 
+<pre>
+new DownloadFilesTask().execute(url1, url2, url3);
+</pre>
+ 
+
+<p>Although it's more complicated than {@link android.os.AsyncTask}, you might want to instead
+create your own {@link java.lang.Thread} or {@link android.os.HandlerThread} class. If you do,
+you should set the thread priority to "background" priority by calling {@link
+android.os.Process#setThreadPriority Process.setThreadPriority()} and passing {@link
+android.os.Process#THREAD_PRIORITY_BACKGROUND}. If you don't set the thread to a lower priority
+this way, then the thread could still slow down your app because it operates at the same priority
+as the UI thread by default.</p>
+ 
+<p>If you implement {@link java.lang.Thread} or {@link android.os.HandlerThread},
+be sure that your UI thread does not block while waiting for the worker thread to
+complete&mdash;do not call {@link java.lang.Thread#wait Thread.wait()} or
+{@link java.lang.Thread#sleep Thread.sleep()}. Instead of blocking while waiting for a worker
+thread to complete, your main thread should provide a {@link
+android.os.Handler} for the other threads to post back to upon completion.
+Designing your application in this way will allow your app's UI thread to remain
+responsive to input and thus avoid ANR dialogs caused by the 5 second input
+event timeout.</p>
+
+<p>The specific constraint on {@link android.content.BroadcastReceiver} execution time
+emphasizes what broadcast receivers are meant to do:
+small, discrete amounts of work in the background such
+as saving a setting or registering a {@link android.app.Notification}. So as with other methods
+called in the UI thread, applications should avoid potentially long-running
+operations or calculations in a broadcast receiver. But instead of doing intensive
+tasks via worker threads, your
+application should start an {@link android.app.IntentService} if a
+potentially long running action needs to be taken in response to an intent
+broadcast.</p>
+
+<p class="note"><strong>Tip:</strong>
+You can use {@link android.os.StrictMode} to help find potentially
+long running operations such as network or database operations that
+you might accidentally be doing your main thread.</p>

+<p>Generally, 100 to 200ms is the threshold beyond which users will perceive
+slowness in an application. As such, here
+are some additional tips beyond what you should do to avoid ANR and
+make your application seem responsive to users:</p>
+
+<ul>
+    <li>If your application is doing work in the background in response to
+    user input, show that progress is being made (such as with a {@link
+    android.widget.ProgressBar} in your UI).</li>
+    
+    <li>For games specifically, do calculations for moves in a worker
+    thread.</li>
+    
+    <li>If your application has a time-consuming initial setup phase, consider
+    showing a splash screen or rendering the main view as quickly as possible, indicate that
+    loading is in progress and fill the information asynchronously. In either case, you should
+    indicate somehow that progress is being made, lest the user perceive that
+    the application is frozen.</li>
+    
+    <li>Use performance tools such as <a href="{@docRoot}tools/help/systrace.html">Systrace</a>
+    and <a href="{@docRoot}tools/help/traceview.html">Traceview</a> to determine bottlenecks
+    in your app's responsiveness.</li>

+
+<p>This document primarily covers micro-optimizations that can improve overall app performance
+when combined, but it's unlikely that these changes will result in dramatic
+performance effects. Choosing the right algorithms and data structures should always be your
+priority, but is outside the scope of this document. You should use the tips in this document
+as general coding practices that you can incorporate into your habits for general code
+efficiency.</p>
+
+<p>There are two basic rules for writing efficient code:</p>
+<ul>
+    <li>Don't do work that you don't need to do.</li>
+    <li>Don't allocate memory if you can avoid it.</li>
+</ul>
+
+<p>One of the trickiest problems you'll face when micro-optimizing an Android
+app is that your app is certain to be running on multiple types of
+hardware. Different versions of the VM running on different
+processors running at different speeds. It's not even generally the case
+that you can simply say "device X is a factor F faster/slower than device Y",
+and scale your results from one device to others. In particular, measurement
+on the emulator tells you very little about performance on any device. There
+are also huge differences between devices with and without a 
+<acronym title="Just In Time compiler">JIT</acronym>: the best
+code for a device with a JIT is not always the best code for a device
+without.</p>
+
+<p>To ensure your app performs well across a wide variety of devices, ensure
+your code is efficient at all levels and agressively optimize your performance.</p>
+
+
+<h2 id="ObjectCreation">Avoid Creating Unnecessary Objects</h2>
+
+<p>Object creation is never free. A generational garbage collector with per-thread allocation
+pools for temporary objects can make allocation cheaper, but allocating memory
+is always more expensive than not allocating memory.</p>
+
+<p>As you allocate more objects in your app, you will force a periodic
+garbage collection, creating little "hiccups" in the user experience. The
+concurrent garbage collector introduced in Android 2.3 helps, but unnecessary work
+should always be avoided.</p>
+
+<p>Thus, you should avoid creating object instances you don't need to.  Some
+examples of things that can help:</p>
+
+<ul>
+    <li>If you have a method returning a string, and you know that its result
+    will always be appended to a {@link java.lang.StringBuffer} anyway, change your signature
+    and implementation so that the function does the append directly,
+    instead of creating a short-lived temporary object.</li>
+    <li>When extracting strings from a set of input data, try
+    to return a substring of the original data, instead of creating a copy.
+    You will create a new {@link java.lang.String} object, but it will share the {@code char[]}
+    with the data. (The trade-off being that if you're only using a small
+    part of the original input, you'll be keeping it all around in memory
+    anyway if you go this route.)</li>
+</ul>
+
+<p>A somewhat more radical idea is to slice up multidimensional arrays into
+parallel single one-dimension arrays:</p>
+
+<ul>
+    <li>An array of {@code int}s is a much better than an array of {@link java.lang.Integer}
+    objects,
+    but this also generalizes to the fact that two parallel arrays of ints
+    are also a <strong>lot</strong> more efficient than an array of {@code (int,int)}
+    objects.  The same goes for any combination of primitive types.</li>
+    
+    <li>If you need to implement a container that stores tuples of {@code (Foo,Bar)}
+    objects, try to remember that two parallel {@code Foo[]} and {@code Bar[]} arrays are
+    generally much better than a single array of custom {@code (Foo,Bar)} objects.
+    (The exception to this, of course, is when you're designing an API for
+    other code to access. In those cases, it's usually better to make a small
+    compromise to the speed in order to achieve a good API design. But in your own internal
+    code, you should try and be as efficient as possible.)</li>
+</ul>
+
+<p>Generally speaking, avoid creating short-term temporary objects if you
+can.  Fewer objects created mean less-frequent garbage collection, which has
+a direct impact on user experience.</p>
+
+
+
+
+<h2 id="PreferStatic">Prefer Static Over Virtual</h2>
+
+<p>If you don't need to access an object's fields, make your method static.
+Invocations will be about 15%-20% faster.
+It's also good practice, because you can tell from the method
+signature that calling the method can't alter the object's state.</p>
+
+
+
+
+
+<h2 id="UseFinal">Use Static Final For Constants</h2>
+
+<p>Consider the following declaration at the top of a class:</p>
+
+<pre>
+static int intVal = 42;
+static String strVal = "Hello, world!";
+</pre>
+
+<p>The compiler generates a class initializer method, called
+<code>&lt;clinit&gt;</code>, that is executed when the class is first used.
+The method stores the value 42 into <code>intVal</code>, and extracts a
+reference from the classfile string constant table for <code>strVal</code>.
+When these values are referenced later on, they are accessed with field
+lookups.</p>
+
+<p>We can improve matters with the "final" keyword:</p>
+
+<pre>
+static final int intVal = 42;
+static final String strVal = "Hello, world!";
+</pre>
+
+<p>The class no longer requires a <code>&lt;clinit&gt;</code> method,
+because the constants go into static field initializers in the dex file.
+Code that refers to <code>intVal</code> will use
+the integer value 42 directly, and accesses to <code>strVal</code> will
+use a relatively inexpensive "string constant" instruction instead of a
+field lookup.</p>
+
+<p class="note"><strong>Note:</strong> This optimization applies only to primitive types and
+{@link java.lang.String} constants, not arbitrary reference types. Still, it's good
+practice to declare constants <code>static final</code> whenever possible.</p>
+
+
+
+
+
+<h2 id="GettersSetters">Avoid Internal Getters/Setters</h2>
+
+<p>In native languages like C++ it's common practice to use getters
+(<code>i = getCount()</code>) instead of accessing the field directly (<code>i
+= mCount</code>). This is an excellent habit for C++ and is often practiced in other
+object oriented languages like C# and Java, because the compiler can
+usually inline the access, and if you need to restrict or debug field access
+you can add the code at any time.</p>
+
+<p>However, this is a bad idea on Android.  Virtual method calls are expensive,
+much more so than instance field lookups.  It's reasonable to follow
+common object-oriented programming practices and have getters and setters
+in the public interface, but within a class you should always access
+fields directly.</p>
+
+<p>Without a <acronym title="Just In Time compiler">JIT</acronym>,
+direct field access is about 3x faster than invoking a
+trivial getter. With the JIT (where direct field access is as cheap as
+accessing a local), direct field access is about 7x faster than invoking a
+trivial getter.</p>
+
+<p>Note that if you're using <a href="{@docRoot}tools/help/proguard.html">ProGuard</a>,
+you can have the best of both worlds because ProGuard can inline accessors for you.</p>
+
+
+
+
+
+<h2 id="Loops">Use Enhanced For Loop Syntax</h2>
+
+<p>The enhanced <code>for</code> loop (also sometimes known as "for-each" loop) can be used
+for collections that implement the {@link java.lang.Iterable} interface and for arrays.
+With collections, an iterator is allocated to make interface calls
+to {@code hasNext()} and {@code next()}. With an {@link java.util.ArrayList},
+a hand-written counted loop is
+about 3x faster (with or without JIT), but for other collections the enhanced
+for loop syntax will be exactly equivalent to explicit iterator usage.</p>
+
+<p>There are several alternatives for iterating through an array:</p>
+
+<pre>
+static class Foo {
+    int mSplat;
+}
+
+Foo[] mArray = ...
+
+public void zero() {
+    int sum = 0;
+    for (int i = 0; i &lt; mArray.length; ++i) {
+        sum += mArray[i].mSplat;
+    }
+}
+
+public void one() {
+    int sum = 0;
+    Foo[] localArray = mArray;
+    int len = localArray.length;
+
+    for (int i = 0; i &lt; len; ++i) {
+        sum += localArray[i].mSplat;
+    }
+}
+
+public void two() {
+    int sum = 0;
+    for (Foo a : mArray) {
+        sum += a.mSplat;
+    }
+}
+</pre>
+
+<p><code>zero()</code> is slowest, because the JIT can't yet optimize away
+the cost of getting the array length once for every iteration through the
+loop.</p>
+
+<p><code>one()</code> is faster. It pulls everything out into local
+variables, avoiding the lookups. Only the array length offers a performance
+benefit.</p>
+
+<p><code>two()</code> is fastest for devices without a JIT, and
+indistinguishable from <strong>one()</strong> for devices with a JIT.
+It uses the enhanced for loop syntax introduced in version 1.5 of the Java
+programming language.</p>
+
+<p>So, you should use the enhanced <code>for</code> loop by default, but consider a
+hand-written counted loop for performance-critical {@link java.util.ArrayList} iteration.</p>
+
+<p class="note"><strong>Tip:</strong>
+Also see Josh Bloch's <em>Effective Java</em>, item 46.</p>
+
+
+
+<h2 id="PackageInner">Consider Package Instead of Private Access with Private Inner Classes</h2>
+
+<p>Consider the following class definition:</p>
+
+<pre>
+public class Foo {
+    private class Inner {
+        void stuff() {
+            Foo.this.doStuff(Foo.this.mValue);
+        }
+    }
+
+    private int mValue;
+
+    public void run() {
+        Inner in = new Inner();
+        mValue = 27;
+        in.stuff();
+    }
+
+    private void doStuff(int value) {
+        System.out.println("Value is " + value);
+    }
+}</pre>
+
+<p>What's important here is that we define a private inner class
+(<code>Foo$Inner</code>) that directly accesses a private method and a private
+instance field in the outer class. This is legal, and the code prints "Value is
+27" as expected.</p>
+
+<p>The problem is that the VM considers direct access to <code>Foo</code>'s
+private members from <code>Foo$Inner</code> to be illegal because
+<code>Foo</code> and <code>Foo$Inner</code> are different classes, even though
+the Java language allows an inner class to access an outer class' private
+members. To bridge the gap, the compiler generates a couple of synthetic
+methods:</p>
+
+<pre>
+/*package*/ static int Foo.access$100(Foo foo) {
+    return foo.mValue;
+}
+/*package*/ static void Foo.access$200(Foo foo, int value) {
+    foo.doStuff(value);
+}</pre>
+
+<p>The inner class code calls these static methods whenever it needs to
+access the <code>mValue</code> field or invoke the <code>doStuff()</code> method
+in the outer class. What this means is that the code above really boils down to
+a case where you're accessing member fields through accessor methods.
+Earlier we talked about how accessors are slower than direct field
+accesses, so this is an example of a certain language idiom resulting in an
+"invisible" performance hit.</p>
+
+<p>If you're using code like this in a performance hotspot, you can avoid the
+overhead by declaring fields and methods accessed by inner classes to have
+package access, rather than private access. Unfortunately this means the fields
+can be accessed directly by other classes in the same package, so you shouldn't
+use this in public API.</p>
+
+
+
+
+<h2 id="AvoidFloat">Avoid Using Floating-Point</h2>
+
+<p>As a rule of thumb, floating-point is about 2x slower than integer on
+Android-powered devices.</p>
+
+<p>In speed terms, there's no difference between <code>float</code> and
+<code>double</code> on the more modern hardware. Space-wise, <code>double</code>
+is 2x larger. As with desktop machines, assuming space isn't an issue, you
+should prefer <code>double</code> to <code>float</code>.</p>
+
+<p>Also, even for integers, some processors have hardware multiply but lack
+hardware divide. In such cases, integer division and modulus operations are
+performed in software&mdash;something to think about if you're designing a
+hash table or doing lots of math.</p>
+
+
+
+
+<h2 id="UseLibraries">Know and Use the Libraries</h2>
+
+<p>In addition to all the usual reasons to prefer library code over rolling
+your own, bear in mind that the system is at liberty to replace calls
+to library methods with hand-coded assembler, which may be better than the
+best code the JIT can produce for the equivalent Java. The typical example
+here is {@link java.lang.String#indexOf String.indexOf()} and
+related APIs, which Dalvik replaces with
+an inlined intrinsic. Similarly, the {@link java.lang.System#arraycopy
+System.arraycopy()} method
+is about 9x faster than a hand-coded loop on a Nexus One with the JIT.</p>
+
+
+<p class="note"><strong>Tip:</strong>
+Also see Josh Bloch's <em>Effective Java</em>, item 47.</p>
+
+
+
+
+<h2 id="NativeMethods">Use Native Methods Carefully</h2>
+
+<p>Developing your app with native code using the
+<a href="{@docRoot}tools/sdk/ndk/index.html">Android NDK</a>
+isn't necessarily more efficient than programming with the
+Java language. For one thing,
+there's a cost associated with the Java-native transition, and the JIT can't
+optimize across these boundaries. If you're allocating native resources (memory
+on the native heap, file descriptors, or whatever), it can be significantly
+more difficult to arrange timely collection of these resources. You also
+need to compile your code for each architecture you wish to run on (rather
+than rely on it having a JIT). You may even have to compile multiple versions
+for what you consider the same architecture: native code compiled for the ARM
+processor in the G1 can't take full advantage of the ARM in the Nexus One, and
+code compiled for the ARM in the Nexus One won't run on the ARM in the G1.</p>
+
+<p>Native code is primarily useful when you have an existing native codebase
+that you want to port to Android, not for "speeding up" parts of your Android app
+written with the Java language.</p>
+
+<p>If you do need to use native code, you should read our
+<a href="{@docRoot}guide/practices/jni.html">JNI Tips</a>.</p>
+
+<p class="note"><strong>Tip:</strong>
+Also see Josh Bloch's <em>Effective Java</em>, item 54.</p>
+
+
+
+
+
+<h2 id="Myths">Performance Myths</h2>
+
+
+<p>On devices without a JIT, it is true that invoking methods via a
+variable with an exact type rather than an interface is slightly more
+efficient. (So, for example, it was cheaper to invoke methods on a
+<code>HashMap map</code> than a <code>Map map</code>, even though in both
+cases the map was a <code>HashMap</code>.) It was not the case that this
+was 2x slower; the actual difference was more like 6% slower. Furthermore,
+the JIT makes the two effectively indistinguishable.</p>
+
+<p>On devices without a JIT, caching field accesses is about 20% faster than
+repeatedly accesssing the field. With a JIT, field access costs about the same
+as local access, so this isn't a worthwhile optimization unless you feel it
+makes your code easier to read. (This is true of final, static, and static
+final fields too.)
+
+
+
+<h2 id="Measure">Always Measure</h2>
+
+<p>Before you start optimizing, make sure you have a problem that you
+need to solve. Make sure you can accurately measure your existing performance,
+or you won't be able to measure the benefit of the alternatives you try.</p>
+
+<p>Every claim made in this document is backed up by a benchmark. The source
+to these benchmarks can be found in the <a
+href="http://code.google.com/p/dalvik/source/browse/#svn/trunk/benchmarks">code.google.com
+"dalvik" project</a>.</p>
+
+<p>The benchmarks are built with the
+<a href="http://code.google.com/p/caliper/">Caliper</a> microbenchmarking
+framework for Java. Microbenchmarks are hard to get right, so Caliper goes out
+of its way to do the hard work for you, and even detect some cases where you're
+not measuring what you think you're measuring (because, say, the VM has
+managed to optimize all your code away). We highly recommend you use Caliper
+to run your own microbenchmarks.</p>
+
+<p>You may also find
+<a href="{@docRoot}tools/debugging/debugging-tracing.html">Traceview</a> useful
+for profiling, but it's important to realize that it currently disables the JIT,
+which may cause it to misattribute time to code that the JIT may be able to win
+back. It's especially important after making changes suggested by Traceview
+data to ensure that the resulting code actually runs faster when run without
+Traceview.</p>

+</div></div>
+
+
+<p>Android has security features built
+into the operating system that significantly reduce the frequency and impact of
+application security issues. The system is designed so you can typically build your apps with
+default system and file permissions and avoid difficult decisions about security.</p>
+
+<p>Some of the core security features that help you build secure apps
+include:
+<ul>
+<li>The Android Application Sandbox, which isolates your app data and code execution
+from other apps.</li>
+<li>An application framework with robust implementations of common
+security functionality such as cryptography, permissions, and secure
+<acronym title="Interprocess Communication">IPC</acronym>.</li>
+<li>Technologies like ASLR, NX, ProPolice, safe_iop, OpenBSD dlmalloc, OpenBSD
+calloc, and Linux mmap_min_addr to mitigate risks associated with common memory
+management errors.</li>
+<li>An encrypted filesystem that can be enabled to protect data on lost or
+stolen devices.</li>
+<li>User-granted permissions to restrict access to system features and user data.</li>
+<li>Application-defined permissions to control application data on a per-app basis.</li>
+</ul>
+
+<p>Nevertheless, it is important that you be familiar with the Android
+security best practices in this document. Following these practices as general coding habits
+will reduce the likelihood of inadvertently introducing security issues that
+adversely affect your users.</p>
+
+
+
+<h2 id="StoringData">Storing Data</h2>
+
+<p>The most common security concern for an application on Android is whether the data
+that you save on the device is accessible to other apps. There are three fundamental
+ways to save data on the device:</p>
+
+<h3 id="InternalStorage">Using internal storage</h3>
+
+<p>By default, files that you create on <a
+href="{@docRoot}guide/topics/data/data-storage.html#filesInternal">internal
+storage</a> are accessible only to your app. This
+protection is implemented by Android and is sufficient for most
+applications.</p>
+
+<p>You should generally avoid using the {@link android.content.Context#MODE_WORLD_WRITEABLE} or
+{@link android.content.Context#MODE_WORLD_READABLE} modes for
+<acronym title="Interprocess Communication">IPC</acronym> files because they do not provide
+the ability to limit data access to particular applications, nor do they
+provide any control on data format. If you want to share your data with other
+app processes, you might instead consider using a
+<a href="{@docRoot}guide/topics/providers/content-providers.html">content provider</a>, which
+offers read and write permissions to other apps and can make
+dynamic permission grants on a case-by-case basis.</p>
+
+<p>To provide additional protection for sensitive data, you might
+choose to encrypt local files using a key that is not directly accessible to the
+application. For example, a key can be placed in a {@link java.security.KeyStore}
+and protected with a user password that is not stored on the device.  While this
+does not protect data from a root compromise that can monitor the user
+inputting the password,  it can provide protection for a lost device without <a
+href="http://source.android.com/tech/encryption/index.html">file system
+encryption</a>.</p>
+
+
+<h3 id="ExternalStorage">Using external storage</h3>
+
+<p>Files created on <a
+href="{@docRoot}guide/topics/data/data-storage.html#filesExternal">external
+storage</a>, such as SD Cards, are globally readable and writable.  Because
+external storage can be removed by the user and also modified by any
+application,  you should not store sensitive information using
+external storage.</p>
+
+<p>As with data from any untrusted source, you should <a href="#InputValidation">perform input
+validation</a> when handling data from external storage.
+We strongly recommend that you not store executables or
+class files on external storage prior to dynamic loading.  If your app
+does retrieve executable files from external storage, the files should be signed and
+cryptographically verified prior to dynamic loading.</p>
+
+
+<h3 id="ContentProviders">Using content providers</h3>
+
+<p><a href="{@docRoot}guide/topics/providers/content-providers.html">Content providers</a>
+offer a structured storage mechanism that can be limited
+to your own application or exported to allow access by other applications.
+If you do not intend to provide other
+applications with access to your {@link android.content.ContentProvider}, mark them as <code><a
+href="{@docRoot}guide/topics/manifest/provider-element.html#exported">
+android:exported=false</a></code> in the application manifest. Otherwise, set the <code><a
+href="{@docRoot}guide/topics/manifest/provider-element.html#exported">android:exported</a></code>
+attribute {@code "true"} to allow other apps to access the stored data.
+</p>
+
+<p>When creating a {@link android.content.ContentProvider}
+that will be exported for use by other applications, you can specify a single
+<a href="{@docRoot}guide/topics/manifest/provider-element.html#prmsn">permission
+</a> for reading and writing, or distinct permissions for reading and writing
+within the manifest. We recommend that you limit your permissions to those
+required to accomplish the task at hand. Keep in mind that it’s usually
+easier to add permissions later to expose new functionality than it is to take
+them away and break existing users.</p>
+
+<p>If you are using a content provider
+for sharing data between only your own apps, it is preferable to use the
+<a href="{@docRoot}guide/topics/manifest/permission-element.html#plevel">{@code
+android:protectionLevel}</a> attribute set to {@code "signature"} protection.
+Signature permissions do not require user confirmation,
+so they provide a better user experience and more controlled access to the
+content provider data when the apps accessing the data are
+<a href="{@docRoot}tools/publishing/app-signing.html">signed</a> with
+the same key.</p>
+
+<p>Content providers can also provide more granular access by declaring the <a
+href="{@docRoot}guide/topics/manifest/provider-element.html#gprmsn">{@code
+android:grantUriPermissions}</a> attribute and using the {@link
+android.content.Intent#FLAG_GRANT_READ_URI_PERMISSION} and {@link
+android.content.Intent#FLAG_GRANT_WRITE_URI_PERMISSION} flags in the
+{@link android.content.Intent} object
+that activates the component.  The scope of these permissions can be further
+limited by the <code><a
+href="{@docRoot}guide/topics/manifest/grant-uri-permission-element.html">
+&lt;grant-uri-permission element&gt;</a></code>.</p>
+
+<p>When accessing a content provider, use parameterized query methods such as 
+{@link android.content.ContentProvider#query(Uri,String[],String,String[],String) query()},
+{@link android.content.ContentProvider#update(Uri,ContentValues,String,String[]) update()}, and
+{@link android.content.ContentProvider#delete(Uri,String,String[]) delete()} to avoid
+potential SQL injection from untrusted sources. Note that using parameterized methods is not
+sufficient if the <code>selection</code> argument is built by concatenating user data
+prior to submitting it to the method.</p>
+
+<p>Do not have a false sense of security about the write permission.  Consider
+that the write permission allows SQL statements which make it possible for some
+data to be confirmed using creative <code>WHERE</code> clauses and parsing the
+results. For example, an attacker might probe for presence of a specific phone
+number in a call-log by modifying a row only if that phone number already
+exists. If the content provider data has predictable structure, the write
+permission may be equivalent to providing both reading and writing.</p>
+
+
+
+
+
+
+
+<h2 id="Permissions">Using Permissions</h2>
+
+<p>Because Android sandboxes applications from each other, applications must explicitly
+share resources and data. They do this by declaring the permissions they need for additional
+capabilities not provided by the basic sandbox, including access to device features such as
+the camera.</p>
+
+
+<h3 id="RequestingPermissions">Requesting Permissions</h3>
+
+<p>We recommend minimizing the number of permissions that your app requests
+Not having access to sensitive permissions reduces the risk of
+inadvertently misusing those permissions, can improve user adoption, and makes
+your app less for attackers. Generally,
+if a permission is not required for your app to function, do not request it.</p>
+
+<p>If it's possible to design your application in a way that does not require
+any permissions, that is preferable.  For example, rather than requesting access
+to device information to create a unique identifier, create a <a
+href="{@docRoot}reference/java/util/UUID.html">GUID</a> for your application
+(see the section about <a href="#UserData">Handling User Data</a>). Or, rather than
+using external storage (which requires permission), store data
+on the internal storage.</p>
+
+<p>In addition to requesting permissions, your application can use the <a
+href="{@docRoot}guide/topics/manifest/permission-element.html">{@code &lt;permissions>}</a>
+to protect IPC that is security sensitive and will be exposed to other
+applications, such as a {@link android.content.ContentProvider}.
+In general, we recommend using access controls
+other than user confirmed permissions where possible because permissions can
+be confusing for users. For example, consider using the <a
+href="{@docRoot}guide/topics/manifest/permission-element.html#plevel">signature
+protection level</a> on permissions for IPC communication between applications
+provided by a single developer.</p>
+
+<p>Do not leak permission-protected data.  This occurs when your app exposes data
+over IPC that is only available because it has a specific permission, but does
+not require that permission of any clients of it’s IPC interface. More
+details on the potential impacts, and frequency of this type of problem is
+provided in this research paper published at USENIX: <a
+href="http://www.cs.berkeley.edu/~afelt/felt_usenixsec2011.pdf">http://www.cs.be
+rkeley.edu/~afelt/felt_usenixsec2011.pdf</a></p>
+
+
+
+<h3 id="CreatingPermissions">Creating Permissions</h3>
+
+<p>Generally, you should strive to define as few permissions as possible while
+satisfying your security requirements.  Creating a new permission is relatively
+uncommon for most applications, because the <a
+href="{@docRoot}reference/android/Manifest.permission.html">system-defined
+permissions</a> cover many situations.  Where appropriate,
+perform access checks using existing permissions.</p>
+
+<p>If you must create a new permission, consider whether you can accomplish
+your task with a <a
+href="{@docRoot}guide/topics/manifest/permission-element.html#plevel">"signature"
+protection level</a>.  Signature permissions are transparent
+to the user and only allow access by applications signed by the same developer
+as application performing the permission check.</p>
+
+<p>If you create a permission with the <a
+href="{@docRoot}guide/topics/manifest/permission-element.html#plevel">"dangerous"
+protection level</a>, there are a number of complexities
+that you need to consider:
+<ul>
+<li>The permission must have a string that concisely expresses to a user the
+security decision they will be required to make.</li>
+<li>The permission string must be localized to many different languages.</li>
+<li>Users may choose not to install an application because a permission is
+confusing or perceived as risky.</li>
+<li>Applications may request the permission when the creator of the permission
+has not been installed.</li>
+</ul>
+
+<p>Each of these poses a significant non-technical challenge for you as the developer
+while also confusing your users,
+which is why we discourage the use of the "dangerous" permission level.</p>
+
+
+
+
+
+<h2 id="Networking">Using Networking</h2>
+
+<p>Network transactions are inherently risky for security, because it involves transmitting
+data that is potentially private to the user. People are increasingly aware of the privacy
+concerns of a mobile device, especially when the device performs network transactions,
+so it's very important that your app implement all best practices toward keeping the user's
+data secure at all times.</p>
+
+<h3 id="IPNetworking">Using IP Networking</h3>
+
+<p>Networking on Android is not significantly different from other Linux
+environments.  The key consideration is making sure that appropriate protocols
+are used for sensitive data, such as {@link javax.net.ssl.HttpsURLConnection} for
+secure web traffic.   We prefer use of HTTPS over HTTP anywhere that HTTPS is
+supported on the server, because mobile devices frequently connect on networks
+that are not secured, such as public Wi-Fi hotspots.</p>
+
+<p>Authenticated, encrypted socket-level communication can be easily
+implemented using the {@link javax.net.ssl.SSLSocket}
+class.  Given the frequency with which Android devices connect to unsecured
+wireless networks using Wi-Fi, the use of secure networking is strongly
+encouraged for all applications that communicate over the network.</p>
+
+<p>We have seen some applications use <a
+href="http://en.wikipedia.org/wiki/Localhost">localhost</a> network ports for
+handling sensitive IPC.  We discourage this approach since these interfaces are
+accessible by other applications on the device.  Instead, you should use an Android IPC
+mechanism where authentication is possible such as with a {@link android.app.Service}.  (Even
+worse than using loopback is to bind to INADDR_ANY since then your application
+may receive requests from anywhere.)</p>
+
+<p>Also, one common issue that warrants repeating is to make sure that you do
+not trust data downloaded from HTTP or other insecure protocols.  This includes
+validation of input in {@link android.webkit.WebView} and
+any responses to intents issued against HTTP.</p>
+
+
+<h3>Using Telephony Networking</h3>
+
+<p>The <acronym title="Short Message Service">SMS</acronym> protocol was primarily designed for
+user-to-user communication and is not well-suited for apps that want to transfer data.
+Due to the limitations of SMS, we strongly recommend the use of <a
+href="{@docRoot}guide/google/gcm/index.html">Google Cloud Messaging</a> (GCM)
+and IP networking for sending data messages from a web server to your app on a user device.</p>
+
+<p>Beware that SMS is neither encrypted nor strongly
+authenticated on either the network or the device.  In particular, any SMS receiver
+should expect that a malicious user may have sent the SMS to your application&mdash;Do
+not rely on unauthenticated SMS data to perform sensitive commands.
+Also, you should be aware that SMS may be subject to spoofing and/or
+interception on the network.  On the Android-powered device itself, SMS
+messages are transmitted as broadcast intents, so they may be read or captured
+by other applications that have the {@link android.Manifest.permission#READ_SMS}
+permission.</p>
+
+
+
+
+
+<h2 id="InputValidation">Performing Input Validation</h2>
+
+<p>Insufficient input validation is one of the most common security problems
+affecting applications, regardless of what platform they run on. Android does
+have platform-level countermeasures that reduce the exposure of applications to
+input validation issues and you should use those features where possible. Also
+note that selection of type-safe languages tends to reduce the likelihood of
+input validation issues.</p>
+
+<p>If you are using native code, then any data read from files, received over
+the network, or received from an IPC has the potential to introduce a security
+issue.  The most common problems are <a
+href="http://en.wikipedia.org/wiki/Buffer_overflow">buffer overflows</a>, <a
+href="http://en.wikipedia.org/wiki/Double_free#Use_after_free">use after
+free</a>, and <a
+href="http://en.wikipedia.org/wiki/Off-by-one_error">off-by-one errors</a>.
+Android provides a number of technologies like <acronym
+title="Address Space Layout Randomization">ASLR</acronym> and <acronym
+title="Data Execution Prevention">DEP</acronym> that reduce the
+exploitability of these errors, but they do not solve the underlying problem.
+You can prevent these vulneratbilities by careful handling pointers and managing
+buffers.</p>
+
+<p>Dynamic, string based languages such as JavaScript and SQL are also subject
+to input validation problems due to escape characters and <a
+href="http://en.wikipedia.org/wiki/Code_injection">script injection</a>.</p>
+
+<p>If you are using data within queries that are submitted to an SQL database or a
+content provider, SQL injection may be an issue.  The best defense is to use
+parameterized queries, as is discussed in the above section about <a
+href="#ContentProviders">content providers</a>.
+Limiting permissions to read-only or write-only can also reduce the potential
+for harm related to SQL injection.</p>
+
+<p>If you cannot use the security features above, we strongly recommend the use
+of well-structured data formats and verifying that the data conforms to the
+expected format. While blacklisting of characters or character-replacement can
+be an effective strategy, these techniques are error-prone in practice and
+should be avoided when possible.</p>
+
+
+
+
+
+<h2 id="UserData">Handling User Data</h2>
+
+<p>In general, the best approach for user data security is to minimize the use of APIs that access
+sensitive or personal user data. If you have access to user data and can avoid
+storing or transmitting the information, do not store or transmit the data.
+Finally, consider if there is a way that your application logic can be
+implemented using a hash or non-reversible form of the data.  For example, your
+application might use the hash of an an email address as a primary key, to
+avoid transmitting or storing the email address.  This reduces the chances of
+inadvertently exposing data, and it also reduces the chance of attackers
+attempting to exploit your application.</p>
+
+<p>If your application accesses personal information such as passwords or
+usernames, keep in mind that some jurisdictions may require you to provide a
+privacy policy explaining your use and storage of that data.  So following the
+security best practice of minimizing access to user data may also simplify
+compliance.</p>
+
+<p>You should also consider whether your application might be inadvertently
+exposing personal information to other parties such as third-party components
+for advertising or third-party services used by your application. If you don't
+know why a component or service requires a personal information, don’t
+provide it.  In general, reducing the access to personal information by your
+application will reduce the potential for problems in this area.</p>
+
+<p>If access to sensitive data is required, evaluate whether that information
+must be transmitted to a server, or whether the operation can be performed on
+the client.  Consider running any code using sensitive data on the client to
+avoid transmitting user data.</p>
+
+<p>Also, make sure that you do not inadvertently expose user data to other
+application on the device through overly permissive IPC, world writable files,
+or network sockets. This is a special case of leaking permission-protected data,
+discussed in the <a href="#RequestingPermissions">Requesting Permissions</a> section.</p>
+
+<p>If a <acronym title="Globally Unique Identifier">GUID</acronym>
+is required, create a large, unique number and store it.  Do not
+use phone identifiers such as the phone number or IMEI which may be associated
+with personal information.  This topic is discussed in more detail in the <a
+href="http://android-developers.blogspot.com/2011/03/identifying-app-installations.html">Android
+Developer Blog</a>.</p>
+
+<p>Be careful when writing to on-device logs.
+In Android, logs are a shared resource, and are available
+to an application with the {@link android.Manifest.permission#READ_LOGS} permission.
+Even though the phone log data
+is temporary and erased on reboot, inappropriate logging of user information
+could inadvertently leak user data to other applications.</p>
+
+
+
+
+
+
+<h2 id="WebView">Using WebView</h2>
+
+<p>Because {@link android.webkit.WebView} consumes web content that can include HTML and JavaScript,
+improper use can introduce common web security issues such as <a
+href="http://en.wikipedia.org/wiki/Cross_site_scripting">cross-site-scripting</a>
+(JavaScript injection).  Android includes a number of mechanisms to reduce
+the scope of these potential issues by limiting the capability of {@link android.webkit.WebView} to
+the minimum functionality required by your application.</p>
+
+<p>If your application does not directly use JavaScript within a {@link android.webkit.WebView}, do
+<em>not</em> call {@link android.webkit.WebSettings#setJavaScriptEnabled setJavaScriptEnabled()}.
+Some sample code uses this method, which you might repurpose in production
+application, so remove that method call if it's not required. By default,
+{@link android.webkit.WebView} does
+not execute JavaScript so cross-site-scripting is not possible.</p>
+
+<p>Use {@link android.webkit.WebView#addJavascriptInterface
+addJavaScriptInterface()} with
+particular care because it allows JavaScript to invoke operations that are
+normally reserved for Android applications.  If you use it, expose 
+{@link android.webkit.WebView#addJavascriptInterface addJavaScriptInterface()} only to
+web pages from which all input is trustworthy.  If untrusted input is allowed,
+untrusted JavaScript may be able to invoke Android methods within your app.  In general, we
+recommend exposing {@link android.webkit.WebView#addJavascriptInterface
+addJavaScriptInterface()} only to JavaScript that is contained within your application APK.</p>
+
+<p>If your application accesses sensitive data with a 
+{@link android.webkit.WebView}, you may want to use the
+{@link android.webkit.WebView#clearCache clearCache()} method to delete any files stored
+locally. Server-side
+headers like <code>no-cache</code> can also be used to indicate that an application should
+not cache particular content.</p>
+
+
+
+
+<h3 id="Credentials">Handling Credentials</h3>
+
+<p>In general, we recommend minimizing the frequency of asking for user
+credentials&mdash;to make phishing attacks more conspicuous, and less likely to be
+successful.  Instead use an authorization token and refresh it.</p>
+
+<p>Where possible, username and password should not be stored on the device.
+Instead, perform initial authentication using the username and password
+supplied by the user, and then use a short-lived, service-specific
+authorization token.</p>
+
+<p>Services that will be accessible to multiple applications should be accessed
+using {@link android.accounts.AccountManager}. If possible, use the
+{@link android.accounts.AccountManager} class to invoke a cloud-based service and do not store
+passwords on the device.</p>
+
+<p>After using {@link android.accounts.AccountManager} to retrieve an
+{@link android.accounts.Account}, {@link android.accounts.Account#CREATOR}
+before passing in any credentials, so that you do not inadvertently pass
+credentials to the wrong application.</p>
+
+<p>If credentials are to be used only by applications that you create, then you
+can verify the application which accesses the {@link android.accounts.AccountManager} using
+{@link android.content.pm.PackageManager#checkSignatures checkSignature()}.
+Alternatively, if only one application will use the credential, you might use a
+{@link java.security.KeyStore} for storage.</p>
+
+
+
+
+
+<h2 id="Crypto">Using Cryptography</h2>
+
+<p>In addition to providing data isolation, supporting full-filesystem
+encryption, and providing secure communications channels, Android provides a
+wide array of algorithms for protecting data using cryptography.</p>
+
+<p>In general, try to use the highest level of pre-existing framework
+implementation that can  support your use case.  If you need to securely
+retrieve a file from a known location, a simple HTTPS URI may be adequate and
+requires no knowledge of cryptography.  If you need a secure
+tunnel, consider using {@link javax.net.ssl.HttpsURLConnection} or
+{@link javax.net.ssl.SSLSocket}, rather than writing your own protocol.</p>
+
+<p>If you do find yourself needing to implement your own protocol, we strongly
+recommend that you <em>not</em> implement your own cryptographic algorithms. Use
+existing cryptographic algorithms such as those in the implementation of AES or
+RSA provided in the {@link javax.crypto.Cipher} class.</p>
+
+<p>Use a secure random number generator, {@link java.security.SecureRandom},
+to initialize any cryptographic keys, {@link javax.crypto.KeyGenerator}.
+Use of a key that is not generated with a secure random
+number generator significantly weakens the strength of the algorithm, and may
+allow offline attacks.</p>
+
+<p>If you need to store a key for repeated use, use a mechanism like
+  {@link java.security.KeyStore} that
+provides a mechanism for long term storage and retrieval of cryptographic
+keys.</p>
+
+
+
+
+
+<h2 id="IPC">Using Interprocess Communication</h2>
+
+<p>Some apps attempt to implement IPC using traditional Linux
+techniques such as network sockets and shared files.  We strongly encourage you to instead
+use Android system functionality for IPC such as {@link android.content.Intent},
+{@link android.os.Binder} or {@link android.os.Messenger} with a {@link
+android.app.Service}, and {@link android.content.BroadcastReceiver}.
+The Android IPC mechanisms allow you to verify the identity of
+the application connecting to your IPC and set security policy for each IPC
+mechanism.</p>
+
+<p>Many of the security elements are shared across IPC mechanisms.
+If your IPC mechanism is not intended for use by other applications, set the
+{@code android:exported} attribute to {@code "false"} in the component's manifest element,
+such as for the <a
+href="{@docRoot}guide/topics/manifest/service-element.html#exported">{@code &lt;service&gt;}</a>
+element.  This is useful for applications that consist of multiple processes
+within the same UID, or if you decide late in development that you do not
+actually want to expose functionality as IPC but you don’t want to rewrite
+the code.</p>
+
+<p>If your IPC is intended to be accessible to other applications, you can
+apply a security policy by using the <a
+href="{@docRoot}guide/topics/manifest/permission-element.html">{@code &lt;permission>}</a>
+element. If IPC is between your own separate apps that are signed with the same key,
+it is preferable to use {@code "signature"} level permission in the <a
+href="{@docRoot}guide/topics/manifest/permission-element.html#plevel">{@code
+android:protectionLevel}</a>.</p>
+
+
+
+
+<h3>Using intents</h3>
+
+<p>Intents are the preferred mechanism for asynchronous IPC in Android.
+Depending on your application requirements, you might use {@link
+android.content.Context#sendBroadcast sendBroadcast()}, {@link
+android.content.Context#sendOrderedBroadcast sendOrderedBroadcast()},
+or an explicit intent to a specific application component.</p>
+
+<p>Note that ordered broadcasts can be “consumed” by a recipient, so they
+may not be delivered to all applications.  If you are sending an intent that muse be delivered
+to a specific receiver, then you must use an explicit intent that declares the receiver
+by nameintent.</p>
+
+<p>Senders of an intent can verify that the recipient has a permission
+specifying a non-Null permission with the method call.  Only applications with that
+permission will receive the intent.  If data within a broadcast intent may be
+sensitive, you should consider applying a permission to make sure that
+malicious applications cannot register to receive those messages without
+appropriate permissions.  In those circumstances, you may also consider
+invoking the receiver directly, rather than raising a broadcast.</p>
+
+<p class="note"><strong>Note:</strong> Intent filters should not be considered
+a security feature&mdash;components
+can be invoked with explicit intents and may not have data that would conform to the intent
+filter. You should perform input validation within your intent receiver to
+confirm that it is properly formatted for the invoked receiver, service, or
+activity.</p>
+
+
+
+
+<h3 id="Services">Using services</h3>
+
+<p>A {@link android.app.Service} is often used to supply functionality for other applications to
+use. Each service class must have a corresponding <a
+href="{@docRoot}guide/topics/manifest/service-element.html">{@code <service>}</a> declaration in its
+manifest file.</p>
+
+<p>By default, services are not exported and cannot be invoked by any other
+application. However, if you add any intent filters to the service declaration, then it is exported
+by default. It's best if you explicitly declare the <a
+href="{@docRoot}guide/topics/manifest/service-element.html#exported">{@code
+android:exported}</a> attribute to be sure it behaves as you'd like.
+Services can also be protected using the <a
+href="{@docRoot}guide/topics/manifest/service-element.html#prmsn">{@code android:permission}</a>
+attribute. By doing so, other applications will need to declare
+a corresponding <code><a
+href="{@docRoot}guide/topics/manifest/uses-permission-element.html">&lt;uses-permission&gt;</a>
+</code> element in their own manifest to be
+able to start, stop, or bind to the service.</p>
+
+<p>A service can protect individual IPC calls into it with permissions, by
+calling {@link android.content.Context#checkCallingPermission
+checkCallingPermission()} before executing
+the implementation of that call.  We generally recommend using the
+declarative permissions in the manifest, since those are less prone to
+oversight.</p>
+
+
+
+<h3>Using binder and messenger interfaces</h3>
+
+<p>Using {@link android.os.Binder} or {@link android.os.Messenger} is the
+preferred mechanism for RPC-style IPC in Android. They provide a well-defined
+interface that enables mutual authentication of the endpoints, if required.</p>
+
+<p>We strongly encourage designing interfaces in a manner that does not require
+interface specific permission checks. {@link android.os.Binder} and
+{@link android.os.Messenger} objects are not declared within the
+application manifest, and therefore you cannot apply declarative permissions
+directly to them.  They generally inherit permissions declared in the
+application manifest for the {@link android.app.Service} or {@link
+android.app.Activity} within which they are
+implemented.  If you are creating an interface that requires authentication
+and/or access controls, those controls must be
+explicitly added as code in the {@link android.os.Binder} or {@link android.os.Messenger}
+interface.</p>
+
+<p>If providing an interface that does require access controls, use {@link
+android.content.Context#checkCallingPermission checkCallingPermission()}
+to verify whether the
+caller has a required permission. This is especially important
+before accessing a service on behalf of the caller, as the identify of your
+application is passed to other interfaces.  If invoking an interface provided
+by a {@link android.app.Service}, the {@link
+android.content.Context#bindService bindService()}
+ invocation may fail if you do not have permission to access the given service.
+ If calling an interface provided locally by your own application, it may be
+useful to use the {@link android.os.Binder#clearCallingIdentity clearCallingIdentity()}
+to satisfy internal security checks.</p>
+
+<p>For more information about performing IPC with a service, see
+<a href="{@docRoot}guide/components/bound-services.html">Bound Services</a>.</p>
+
+
+
+<h3 id="BroadcastReceivers">Using broadcast receivers</h3>
+
+<p>A {@link android.content.BroadcastReceiver} handles asynchronous requests initiated by
+an {@link android.content.Intent}.</p>
+
+<p>By default, receivers are exported and can be invoked by any other
+application. If your {@link android.content.BroadcastReceiver}
+is intended for use by other applications, you
+may want to apply security permissions to receivers using the <code><a
+href="{@docRoot}guide/topics/manifest/receiver-element.html">
+&lt;receiver&gt;</a></code> element within the application manifest.  This will
+prevent applications without appropriate permissions from sending an intent to
+the {@link android.content.BroadcastReceiver}.</p>
+
+
+
+
+
+
+
+
+<h2 id="DynamicCode">Dynamically Loading Code</h2>
+
+<p>We strongly discourage loading code from outside of your application APK.
+Doing so significantly increases the likelihood of application compromise due
+to code injection or code tampering.  It also adds complexity around version
+management and application testing.  Finally, it can make it impossible to
+verify the behavior of an application, so it may be prohibited in some
+environments.</p>
+
+<p>If your application does dynamically load code, the most important thing to
+keep in mind about dynamically loaded code is that it runs with the same
+security permissions as the application APK.  The user made a decision to
+install your application based on your identity, and they are expecting that
+you provide any code run within the application, including code that is
+dynamically loaded.</p>
+
+<p>The major security risk associated with dynamically loading code is that the
+code needs to come from a verifiable source. If the modules are included
+directly within your APK, then they cannot be modified by other applications.
+This is true whether the code is a native library or a class being loaded using
+{@link dalvik.system.DexClassLoader}.  We have seen many instances of applications
+attempting to load code from insecure locations, such as downloaded from the
+network over unencrypted protocols or from world writable locations such as
+external storage. These locations could allow someone on the network to modify
+the content in transit, or another application on a users device to modify the
+content on the device, respectively.</p>
+
+
+
+
+
+<h2 id="Dalvik">Security in a Virtual Machine</h2>
+
+<p>Dalvik is Android's runtime virtual machine (VM). Dalvik was built specifically for Android,
+but many of the concerns regarding secure code in other virtual machines also apply to Android.
+In general, you shouldn't concern yourself with security issues relating to the virtual machine.
+Your application runs in a secure sandbox environment, so other processes on the system cannnot
+access your code or private data.</p>
+
+<p>If you're interested in diving deeper on the subject of virtual machine security,
+we recommend that you familiarize yourself with some
+existing literature on the subject. Two of the more popular resources are:
+<ul>

+
+<p>This document is focused on the areas which are Android specific or
+different from other VM environments.  For developers experienced with VM
+programming in other environments, there are two broad issues that may be
+different about writing apps for Android:
+<ul>
+<li>Some virtual machines, such as the JVM or .net runtime, act as a security
+boundary, isolating code from the underlying operating system capabilities.  On
+Android, the Dalvik VM is not a security boundary&mdash;the application sandbox is
+implemented at the OS level, so Dalvik can interoperate with native code in the
+same application without any security constraints.</li>
+
+<li>Given the limited storage on mobile devices, it’s common for developers
+to want to build modular applications and use dynamic class loading.  When
+doing this, consider both the source where you retrieve your application logic
+and where you store it locally. Do not use dynamic class loading from sources
+that are not verified, such as unsecured network sources or external storage,
+because that code might be modified to include malicious behavior.</li>
+</ul>
+
+
+
+<h2 id="Native">Security in Native Code</h2>
+
+<p>In general, we encourage developers to use the Android SDK for
+application development, rather than using native code with the
+<a href="{@docRoot}tools/sdk/ndk/index.html">Android NDK</a>.  Applications built
+with native code are more complex, less portable, and more like to include
+common memory corruption errors such as buffer overflows.</p>
+
+<p>Android is built using the Linux kernel and being familiar with Linux
+development security best practices is especially useful if you are going to
+use native code. Linux security practices are beyond the scope of this document,
+but one of the most popular resources is “Secure Programming for
+Linux and Unix HOWTO”, available at <a
+href="http://www.dwheeler.com/secure-programs">
+http://www.dwheeler.com/secure-programs</a>.</p>
+
+<p>An important difference between Android and most Linux environments is the
+Application Sandbox.  On Android, all applications run in the Application
+Sandbox, including those written with native code.  At the most basic level, a
+good way to think about it for developers familiar with Linux is to know that
+every application is given a unique <acronym title="User Identifier">UID</acronym>
+with very limited permissions. This is discussed in more detail in the <a
+href="http://source.android.com/tech/security/index.html">Android Security
+Overview</a> and you should be familiar with application permissions even if
+you are using native code.</p>

+</ul>
+
+
+</div>
+</div>
+
+
+<p>This lesson explains how to create and issue a notification.</p>
+
+<p>The examples in this class are based on the 
+{@link android.support.v4.app.NotificationCompat.Builder} class. 
+{@link android.support.v4.app.NotificationCompat.Builder} 
+is in the <a href="{@docRoot}">Support Library</a>. You should use
+{@link android.support.v4.app.NotificationCompat} and its subclasses,
+particularly {@link android.support.v4.app.NotificationCompat.Builder}, to
+provide the best notification support for a wide range of platforms. </p>
+
+<h2 id="builder">Create a Notification Builder</h2>
+
+<p>When creating a notification, specify the UI content and actions with a 
+{@link android.support.v4.app.NotificationCompat.Builder} object. At bare minimum, 
+a {@link android.support.v4.app.NotificationCompat.Builder Builder} 
+object must include the following:</p>
+
+<ul>
+  <li>
+        A small icon, set by
+        {@link android.support.v4.app.NotificationCompat.Builder#setSmallIcon setSmallIcon()}
+    </li>
+    <li>
+        A title, set by
+        {@link android.support.v4.app.NotificationCompat.Builder#setContentTitle setContentTitle()}
+    </li>
+    <li>
+        Detail text, set by
+        {@link android.support.v4.app.NotificationCompat.Builder#setContentText setContentText()}
+    </li>
+</ul>
+<p> For example: </p>
+<pre>
+NotificationCompat.Builder mBuilder =
+    new NotificationCompat.Builder(this)
+    .setSmallIcon(R.drawable.notification_icon)
+    .setContentTitle(&quot;My notification&quot;)
+    .setContentText(&quot;Hello World!&quot;);
+</pre>
+
+<h2 id="action">Define the Notification's Action</h2>
+
+
+<p>Although actions are optional, you should add at least one action to your
+notification. An action takes users directly from the notification to an
+{@link android.app.Activity} in your application, where they can look at the
+event that caused the notification or do further work. Inside a notification, the action itself is
+defined by a {@link android.app.PendingIntent} containing an {@link
+android.content.Intent} that starts an {@link android.app.Activity} in your
+application.</p>
+
+<p>How you construct the {@link android.app.PendingIntent} depends on what type
+of {@link android.app.Activity} you're starting. When you start an {@link
+android.app.Activity} from a notification, you must preserve the user's expected
+navigation experience. In the snippet below, clicking the notification opens a
+new activity that effectively extends the behavior of the notification. In this
+case there is no need to create an artificial back stack (see 
+<a href="navigation.html">Preserving Navigation when Starting an Activity</a> for
+more information):</p>
+
+<pre>Intent resultIntent = new Intent(this, ResultActivity.class);
+...
+// Because clicking the notification opens a new ("special") activity, there's
+// no need to create an artificial back stack.
+PendingIntent resultPendingIntent =
+    PendingIntent.getActivity(
+    this,
+    0,
+    resultIntent,
+    PendingIntent.FLAG_UPDATE_CURRENT
+);
+</pre>
+
+<h2 id="click">Set the Notification's Click Behavior</h2>
+
+<p>
+To associate the {@link android.app.PendingIntent} created in the previous
+step with a gesture, call the appropriate method of {@link
+android.support.v4.app.NotificationCompat.Builder}. For example, to start an
+activity when the user clicks the notification text in the notification drawer,
+add the {@link android.app.PendingIntent} by calling {@link
+android.support.v4.app.NotificationCompat.Builder#setContentIntent
+setContentIntent()}. For example:</p>
+
+<pre>PendingIntent resultPendingIntent;
+...
+mBuilder.setContentIntent(resultPendingIntent);</pre>
+
+<h2 id="notify">Issue the Notification</h2>
+
+<p>To issue the notification:</p>
+<ul>
+<li>Get an instance of {@link android.app.NotificationManager}.</li> 
+
+<li>Use the {@link android.app.NotificationManager#notify notify()} method to issue the
+notification. When you call {@link android.app.NotificationManager#notify notify()}, specify a notification ID. 
+You can use this ID to update the notification later on. This is described in more detail in 
+<a href="managing.html">Managing Notifications</a>.</li>
+
+<li>Call {@link
+android.support.v4.app.NotificationCompat.Builder#build() build()}, which
+returns a {@link android.app.Notification} object containing your
+specifications.</li>
+
+<p>For example:</p>
+
+<pre>
+// Sets an ID for the notification
+int mNotificationId = 001;
+// Gets an instance of the NotificationManager service
+NotificationManager mNotifyMgr = 
+        (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
+// Builds the notification and issues it.
+mNotifyMgr.notify(mNotificationId, builder.build());
+</pre>

+    Notifications can include an animated progress indicator that shows users the status
+    of an ongoing operation. If you can estimate how long the operation takes and how much of it
+    is complete at any time, use the "determinate" form of the indicator
+    (a progress bar). If you can't estimate the length of the operation, use the
+    "indeterminate" form of the indicator (an activity indicator).
+</p>
+<p>
+    Progress indicators are displayed with the platform's implementation of the
+    {@link android.widget.ProgressBar} class.
+</p>
+<p>
+    To use a progress indicator, call
+    {@link android.support.v4.app.NotificationCompat.Builder#setProgress setProgress()}. The
+    determinate and indeterminate forms are described in the following sections.
+</p>
+<!-- ------------------------------------------------------------------------------------------ -->
+<h2 id="FixedProgress">Display a Fixed-duration Progress Indicator</h2>
+<p>
+    To display a determinate progress bar, add the bar to your notification by calling
+    {@link android.support.v4.app.NotificationCompat.Builder#setProgress 
+    setProgress(max, progress, false)} and then issue the notification. 
+    The third argument is a boolean that indicates whether the 
+    progress bar is indeterminate (<strong>true</strong>) or determinate (<strong>false</strong>).
+    As your operation proceeds,
+    increment <code>progress</code>, and update the notification. At the end of the operation,
+    <code>progress</code> should equal <code>max</code>. A common way to call
+    {@link android.support.v4.app.NotificationCompat.Builder#setProgress setProgress()}
+    is to set <code>max</code> to 100 and then increment <code>progress</code> as a
+    "percent complete" value for the operation.
+</p>
+<p>
+    You can either leave the progress bar showing when the operation is done, or remove it. In
+    either case, remember to update the notification text to show that the operation is complete.
+    To remove the progress bar, call
+    {@link android.support.v4.app.NotificationCompat.Builder#setProgress 
+    setProgress(0, 0, false)}. For example:
+</p>
+<pre>
+...
+mNotifyManager =
+        (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
+mBuilder = new NotificationCompat.Builder(this);
+mBuilder.setContentTitle("Picture Download")
+    .setContentText("Download in progress")
+    .setSmallIcon(R.drawable.ic_notification);
+// Start a lengthy operation in a background thread
+new Thread(
+    new Runnable() {
+        &#64;Override
+        public void run() {
+            int incr;
+            // Do the "lengthy" operation 20 times
+            for (incr = 0; incr &lt;= 100; incr+=5) {
+                    // Sets the progress indicator to a max value, the
+                    // current completion percentage, and "determinate"
+                    // state
+                    mBuilder.setProgress(100, incr, false);
+                    // Displays the progress bar for the first time.
+                    mNotifyManager.notify(0, mBuilder.build());
+                        // Sleeps the thread, simulating an operation
+                        // that takes time
+                        try {
+                            // Sleep for 5 seconds
+                            Thread.sleep(5*1000);
+                        } catch (InterruptedException e) {
+                            Log.d(TAG, "sleep failure");
+                        }
+            }
+            // When the loop is finished, updates the notification
+            mBuilder.setContentText("Download complete")
+            // Removes the progress bar

+            mNotifyManager.notify(ID, mBuilder.build());
+        }
+    }
+// Starts the thread by calling the run() method in its Runnable
+).start();
+</pre>

+<!-- ------------------------------------------------------------------------------------------ -->
+<h2 id="ActivityIndicator">Display a Continuing Activity Indicator</h2>
+<p>
+    To display a continuing (indeterminate) activity indicator, add it to your notification with
+    {@link android.support.v4.app.NotificationCompat.Builder#setProgress setProgress(0, 0, true)}
+    and issue the notification. The first two arguments are ignored, and the third argument  
+    declares that the indicator is indeterminate. The result is an indicator
+    that has the same style as a progress bar, except that its animation is ongoing.
+</p>
+<p>
+    Issue the notification at the beginning of the operation. The animation will run until you
+    modify your notification. When the operation is done, call
+    {@link android.support.v4.app.NotificationCompat.Builder#setProgress 
+    setProgress(0, 0, false)} and then update the notification to remove the activity indicator.
+    Always do this; otherwise, the animation will run even when the operation is complete. Also
+    remember to change the notification text to indicate that the operation is complete.
+</p>
+<p>
+    To see how continuing activity indicators work, refer to the preceding snippet. Locate the following lines:
+</p>
+<pre>
+// Sets the progress indicator to a max value, the current completion
+// percentage, and "determinate" state
+mBuilder.setProgress(100, incr, false);
+// Issues the notification
+mNotifyManager.notify(0, mBuilder.build());
+</pre>
+<p>
+    Replace the lines you've found with the following lines. Notice that the third parameter
+    in the {@link android.support.v4.app.NotificationCompat.Builder#setProgress setProgress()} 
+    call is set to {@code true} to indicate that the progress bar is
+    indeterminate:
+</p>
+<pre>
+ // Sets an activity indicator for an operation of indeterminate length
+mBuilder.setProgress(0, 0, true);
+// Issues the notification
+mNotifyManager.notify(0, mBuilder.build());
+</pre>
+<p>
+    The resulting indicator is shown in figure 2:
+</p>
+<img
+    id="figure2"
+    src="{@docRoot}images/ui/notifications/activity_indicator.png"
+    height="99"

+<p>Notifications in the notification drawer appear in two main visual styles,
+normal view and big view. The big view of a notification only appears when the
+notification is expanded. This happens when the notification is at the top of
+the drawer, or the user clicks the notification. </p>
+
+<p>Big views were introduced in
+Android 4.1, and they're not supported on older devices. This lesson describes
+how to incorporate big view notifications into your app while still providing
+full functionality via the normal view. See the <a
+href="{@docRoot}guide/topics/ui/notifiers/notifications.html#BigNotify">
+Notifications API guide</a> for more discussion of big views.</p>
+
+<p>Here is an example of a normal view: </p>
+
+<img src="{@docRoot}images/training/notifications-normalview.png" width="300" height="58" alt="normal view" />
+
+<p class="img-caption">
+  <strong>Figure 1.</strong> Normal view notification.
+</p>
+
+
+<p>Here is an example of a big view:</p>
+
+<img src="{@docRoot}images/training/notifications-bigview.png" width="300" height="143" alt="big view" />
+<p class="img-caption">
+  <strong>Figure 2.</strong> Big view notification.
+</p>
+
+
+<p> In the sample application shown in this lesson, both the normal view and the
+big view give users access to same functionality:</p>
+
+<ul>
+ <li>The ability to snooze or dismiss the notification.</li>
+ <li>A way to view the reminder text the user set as part of the timer.</li>
+</ul>
+
+<p>The normal view provides these features through a new activity that launches
+when the user clicks the notification. Keep this in mind as you design your notifications&mdash;first 
+provide the functionality in the normal view, since
+this is how many users will interact with the notification.</p>
+
+<h2 id="activity">Set Up the Notification to Launch a New Activity</h2>
+
+<p>The sample application uses an {@link android.app.IntentService} subclass ({@code PingService})
+to construct and issue the notification.</p>
+
+
+<p>In this snippet, the
+{@link android.app.IntentService} method
+{@link android.app.IntentService#onHandleIntent onHandleIntent()} specifies the new activity 
+that will be launched if the user
+clicks the notification itself. The method 
+{@link android.support.v4.app.NotificationCompat.Builder#setContentIntent setContentIntent()} 
+defines a pending intent that should be fired when the user
+clicks the notification, thereby launching the activity.</p>
+
+<pre>Intent resultIntent = new Intent(this, ResultActivity.class);
+resultIntent.putExtra(CommonConstants.EXTRA_MESSAGE, msg);
+resultIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | 
+        Intent.FLAG_ACTIVITY_CLEAR_TASK);
+     
+// Because clicking the notification launches a new ("special") activity, 
+// there's no need to create an artificial back stack.
+PendingIntent resultPendingIntent =
+         PendingIntent.getActivity(
+         this,
+         0,
+         resultIntent,
+         PendingIntent.FLAG_UPDATE_CURRENT
+);
+
+// This sets the pending intent that should be fired when the user clicks the
+// notification. Clicking the notification launches a new activity.
+builder.setContentIntent(resultPendingIntent);
+</pre>
+
+<h2 id="big-view">Construct the Big View</h2>
+
+<p>This snippet shows how to set up the buttons that will appear in the big view:</p>
+
+<pre>
+// Sets up the Snooze and Dismiss action buttons that will appear in the
+// big view of the notification.
+Intent dismissIntent = new Intent(this, PingService.class);
+dismissIntent.setAction(CommonConstants.ACTION_DISMISS);
+PendingIntent piDismiss = PendingIntent.getService(this, 0, dismissIntent, 0);
+
+Intent snoozeIntent = new Intent(this, PingService.class);
+snoozeIntent.setAction(CommonConstants.ACTION_SNOOZE);
+PendingIntent piSnooze = PendingIntent.getService(this, 0, snoozeIntent, 0);
+</pre>
+
+<p>This snippet shows how to construct the 
+{@link android.support.v4.app.NotificationCompat.Builder Builder} object. 
+It sets the style for the big
+view to be "big text," and sets its content to be the reminder message. It uses
+{@link android.support.v4.app.NotificationCompat.Builder#addAction addAction()}
+to add the <strong>Snooze</strong> and <strong>Dismiss</strong> buttons (and
+their associated pending intents) that will appear in the notification's
+big view:</p>
+
+<pre>// Constructs the Builder object.
+NotificationCompat.Builder builder =
+        new NotificationCompat.Builder(this)
+        .setSmallIcon(R.drawable.ic_stat_notification)
+        .setContentTitle(getString(R.string.notification))
+        .setContentText(getString(R.string.ping))
+        .setDefaults(Notification.DEFAULT_ALL) // requires VIBRATE permission
+        /*
+         * Sets the big view "big text" style and supplies the
+         * text (the user's reminder message) that will be displayed
+         * in the detail area of the expanded notification.
+         * These calls are ignored by the support library for
+         * pre-4.1 devices.
+         */
+        .setStyle(new NotificationCompat.BigTextStyle()
+                .bigText(msg))
+        .addAction (R.drawable.ic_stat_dismiss,
+                getString(R.string.dismiss), piDismiss)
+        .addAction (R.drawable.ic_stat_snooze,
+                getString(R.string.snooze), piSnooze);

+    When you need to issue a notification multiple times for the same type of event, you
+    should avoid making a completely new notification. Instead, you should consider updating a
+    previous notification, either by changing some of its values or by adding to it, or both.
+</p>
+
+<p>
+    The following section describes how to update notifications and also how to remove them.
+</p>
+<h2 id="Updating">Modify a Notification</h2>
+<p>
+    To set up a notification so it can be updated, issue it with a notification ID by
+    calling {@link android.app.NotificationManager#notify(int, Notification)
+    NotificationManager.notify(ID, notification)}. To update this notification once you've issued
+    it, update or create a {@link android.support.v4.app.NotificationCompat.Builder} object,
+    build a {@link android.app.Notification} object from it, and issue the
+    {@link android.app.Notification} with the same ID you used previously.
+</p>
+<p>
+    The following snippet demonstrates a notification that is updated to reflect the
+    number of events that have occurred. It stacks the notification, showing a summary:
+</p>
+<pre>
+mNotificationManager =
+        (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
+// Sets an ID for the notification, so it can be updated
+int notifyID = 1;
+mNotifyBuilder = new NotificationCompat.Builder(this)
+    .setContentTitle("New Message")
+    .setContentText("You've received new messages.")
+    .setSmallIcon(R.drawable.ic_notify_status)
+numMessages = 0;
+// Start of a loop that processes data and then notifies the user
+...
+    mNotifyBuilder.setContentText(currentText)
+        .setNumber(++numMessages);
+    // Because the ID remains unchanged, the existing notification is
+    // updated.
+    mNotificationManager.notify(
+            notifyID,
+            mNotifyBuilder.build());
+...
+</pre>
+
+<!-- ------------------------------------------------------------------------------------------ -->
+<h2 id="Removing">Remove Notifications</h2>
+<p>
+    Notifications remain visible until one of the following happens:
+</p>
+<ul>
+    <li>
+        The user dismisses the notification either individually or by using "Clear All" (if
+        the notification can be cleared).
+    </li>
+    <li>
+        The user touches the notification, and you called
+        {@link android.support.v4.app.NotificationCompat.Builder#setAutoCancel setAutoCancel()} when
+        you created the notification.
+    </li>
+    <li>
+        You call {@link android.app.NotificationManager#cancel(int) cancel()} for a specific
+        notification ID. This method also deletes ongoing notifications.
+    </li>
+    <li>
+        You call {@link android.app.NotificationManager#cancelAll() cancelAll()}, which removes
+        all of the notifications you previously issued.
+    </li>

+    Part of designing a notification is preserving the user's expected navigation experience. 
+    For a detailed discussion of this topic, see the
+    <a href="{@docRoot}guide/topics/ui/notifiers/notifications.html#NotificationResponse">Notifications</a>
+    API guide.
+    There are two general situations:
+</p>
+<dl>
+    <dt>
+        Regular activity
+    </dt>
+    <dd>
+        You're starting an {@link android.app.Activity} that's part of the application's normal
+        workflow. 
+    </dd>
+    <dt>
+        Special activity
+    </dt>
+    <dd>
+        The user only sees this {@link android.app.Activity} if it's started from a notification.
+        In a sense, the {@link android.app.Activity} extends the notification by providing
+        information that would be hard to display in the notification itself.
+    </dd>
+</dl>
+<!-- ------------------------------------------------------------------------------------------ -->
+<h2 id="DirectEntry">Set Up a Regular Activity PendingIntent</h2>
+<p>
+    To set up a {@link android.app.PendingIntent} that starts a direct entry
+    {@link android.app.Activity}, follow these steps:
+</p>
+<ol>
+    <li>
+        Define your application's {@link android.app.Activity} hierarchy in the manifest. The final XML should look like this:
+        </p>
+<pre>
+&lt;activity
+    android:name=".MainActivity"
+    android:label="&#64;string/app_name" &gt;
+    &lt;intent-filter&gt;
+        &lt;action android:name="android.intent.action.MAIN" /&gt;
+        &lt;category android:name="android.intent.category.LAUNCHER" /&gt;
+    &lt;/intent-filter&gt;
+&lt;/activity&gt;
+&lt;activity
+    android:name=".ResultActivity"
+    android:parentActivityName=".MainActivity"&gt;
+    &lt;meta-data
+        android:name="android.support.PARENT_ACTIVITY"
+        android:value=".MainActivity"/&gt;
+&lt;/activity&gt;
+</pre>
+    </li>
+    <li>
+        Create a back stack based on the {@link android.content.Intent} that starts the
+        {@link android.app.Activity}. For example:
+</p>
+<pre>
+...
+Intent resultIntent = new Intent(this, ResultActivity.class);
+TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
+// Adds the back stack
+stackBuilder.addParentStack(ResultActivity.class);
+// Adds the Intent to the top of the stack
+stackBuilder.addNextIntent(resultIntent);
+// Gets a PendingIntent containing the entire back stack
+PendingIntent resultPendingIntent =
+        stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
+...
+NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
+builder.setContentIntent(resultPendingIntent);
+NotificationManager mNotificationManager =
+    (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
+mNotificationManager.notify(id, builder.build());
+</pre>
+<!-- ------------------------------------------------------------------------------------------ -->
+<h2 id="ExtendedNotification">Set Up a Special Activity PendingIntent</h2>
+
+<p>
+    A special {@link android.app.Activity} doesn't need a back stack, so you don't have to
+    define its {@link android.app.Activity} hierarchy in the manifest, and you don't have
+    to call
+    {@link android.support.v4.app.TaskStackBuilder#addParentStack  addParentStack()} to build a
+    back stack. Instead, use the manifest to set up the {@link android.app.Activity} task options,
+    and create the {@link android.app.PendingIntent} by calling
+    {@link android.app.PendingIntent#getActivity getActivity()}:
+</p>
+<ol>
+    <li>
+        In your manifest, add the following attributes to the
+<code><a href="{@docRoot}guide/topics/manifest/activity-element.html">&lt;activity&gt;</a></code>
+        element for the {@link android.app.Activity}:
+        <dl>
+            <dt>
+<code><a href="{@docRoot}guide/topics/manifest/activity-element.html#nm">android:name</a>="<i>activityclass</i>"</code>
+            </dt>
+            <dd>
+                The activity's fully-qualified class name.
+            </dd>
+            <dt>
+<code><a href="{@docRoot}guide/topics/manifest/activity-element.html#aff">android:taskAffinity</a>=""</code>
+            </dt>
+            <dd>
+                Combined with the
+                {@link android.content.Intent#FLAG_ACTIVITY_NEW_TASK FLAG_ACTIVITY_NEW_TASK} flag
+                that you set in code, this ensures that this {@link android.app.Activity} doesn't
+                go into the application's default task. Any existing tasks that have the
+                application's default affinity are not affected.
+            </dd>
+            <dt>
+<code><a href="{@docRoot}guide/topics/manifest/activity-element.html#exclude">android:excludeFromRecents</a>="true"</code>
+            </dt>
+            <dd>
+                Excludes the new task from <i>Recents</i>, so that the user can't accidentally
