+<h2 id="api-level">API Level</h2>
+
+<p>The Android {@sdkPlatformVersion} platform delivers an updated version of
+the framework API. The Android {@sdkPlatformVersion} API
+is assigned an integer identifier &mdash;
+<strong>{@sdkPlatformApiLevel}</strong> &mdash; that is
+stored in the system itself. This identifier, called the "API Level", allows the
+system to correctly determine whether an application is compatible with
+the system, prior to installing the application. </p>
+
+<p>To use APIs introduced in Android {@sdkPlatformVersion} in your
+application, you need to set the proper value, "{@sdkPlatformApiLevel}", in the
+<code>android:minSdkVersion</code> attributes of the <code>&lt;uses-sdk&gt;</code>
+element in your application's manifest. </p>
+
+<p>For more information about how to use API Level, see the <a
+href="{@docRoot}guide/appendix/api-levels.html">API Levels</a> document. </p>
+
+
+<h2 id="api">Framework API Changes</h2>
+
+<p>The sections below provide information about changes made to the application
+framework API provided by the Android {@sdkPlatformVersion} platform.</p>
+
+<h3 id="install-loc">App installation on external storage media</h3>
+
+<p>The Android platform now allows applications to request installation onto the
+device's external storage media (such as the SD card), as an alternative to
+installation onto the device's internal memory. </p>
+
+<p>Application developers can express the preferred installation location for
+their applications by means of a new attribute of <code>&lt;manifest&gt;</code>
+in the manifest file, <a
+href="{@docRoot}guide/topics/manifest/manifest-element.html#install"><code>
+android:installLocation</code></a>. The attribute supports three values:
+<code>"internalOnly"</code>, <code>"preferExternal"</code>, and
+<code>"auto"</code>. At install time, the system checks the value of
+<code>android:installLocation</code> and installs the application
+<code>.apk</code> according to the preferred location, if possible. If the
+application has requested external installation, the system installs it into a
+private, encrypted partition in the external media. Once an application .apk is
+installed externally, the system lets the user change the storage location of
+the .apk and move it onto the device's internal memory if needed (and vice
+versa), through Manage Applications in the user settings.</p>
+
+<p>By default, the system installs all applications onto the device's internal
+memory, except for those that explicitly request external installation. This
+means that the system will always install legacy applications onto internal
+memory, since they do not have access to the
+<code>android:installLocation</code> attribute. However, it is possible to
+configure and compile a legacy application such that it is installed internally
+on older versions of the platform and externally on Android 2.2 and later
+platforms, if necessary. </p>
+
+<p>Note that requesting installation onto the device's external media is not
+suitable for all applications, particularly because the external media may be
+removable and unmounting/remounting may disrupt the user experience and system
+settings.</p>
+
+<p>For more information about setting a preferred install location for your
+application, including a discussion of what types of applications should and
+should not request external installation, please read the <a
+href="{@docRoot}guide/appendix/install-location.html">App Install Location</a>
+document. </p>
+
+<h3 id="backup-manager">Data backup</h3>
+
+<p>The platform now provides a generalized backup service that
+applications can use to backup and restore user data, to ensure that users can
+maintain their data when switching devices or reinstalling the application. The
+Backup Manager handles the work of transporting the application data to and from
+the backup storage area in the cloud. The Backup Manager can store any type of
+data, from arbitrary data to files, and manages backup and restore operations
+in an atomic manner. For more information, see <a
+href="{@docRoot}guide/topics/data/backup.html">Data Backup</a>.</p>
+

See {@link android.media.MediaScannerConnection#scanFile(Context, String[], String[], OnScanCompletedListener) MediaScannerConnection.scanFile} and {@link android.media.MediaScannerConnection.OnScanCompletedListener MediaScannerConnection.OnScanCompletedListener}.</li>
+</ul>
+
+<h3>Speech recognition and third-party recognition engines</h3>
+
+<ul>
+<li>The platform provides new speech-recognition APIs that allow applications to have a richer interaction with the available voice recognizer. For example, the APIs are sufficient to integrate voice recognition deeply into an IME.</li>
+<li>The platform also provides a {@link android.speech.RecognitionService} base class that lets third-party developers create plug-in recognition engines. </li>
+<li>New {@link android.speech.RecognitionListener} interface to receive callbacks.</li>
+<li>New {@link android.speech.RecognizerIntent} extras that let a requester app specify details as preferred language, minimum length in milliseconds, and so on.</li>
+</ul>
+
+<h3>Camera and camcorder</h3>
+
+<ul>
+<li>Changes to camera preview API to improve efficieny of preview pipeline. </li>

+<li>New {@link android.media.CamcorderProfile} and {@link android.media.CamcorderProfile} classes enable apps to determine device hardware camera capablities.</li>
+<li>New support in {@link android.media.ExifInterface android.media.ExifInterface} for retrieving GPS and focal length.</li>
+</ul>
+
+<h3>Device policy manager</h3>
+
+<p>New device policy management APIs allow developers to write "device
+administrator" applications that can control security features of the device,
+such as the minimum password strength, data wipe, and so on. Users can select
+the administrators that are enabled on their devices. For more information, see
+the {@link android.app.admin android.app.admin} classees or the example
+application code in <a
+href="{@docRoot}resources/samples/ApiDemos/src/com/example/android/apis/app/DeviceAdminSample.html">DeviceAdminSample.java</a>.</p>
+
+<h3>UI Framework</h3>

+<li>The layout attribute <code>fill_parent</code> is renamed to <code>match_parent</code>. This affects both XML and Java code (see {@link android.view.ViewGroup.LayoutParams}). Note that the platform will continue to honor uses of <code>fill_parent</code> in legacy applications. </li>
+<li>New layout attributes {@link android.R.attr#tabStripEnabled}, {@link android.R.attr#tabStripRight}, and {@link android.R.attr#tabStripLeft} let developers customize the bottom strip of TabWidgets.</li>
+<li>Better support for managed dialogs in Activity.</li>
+</ul>
+
+<h3>Accounts and sync</h3>
+
+<ul>
+<li>New method {@link android.content.ContentResolver#addPeriodicSync(Account, String, Bundle, long) AddPeriodicSync()} lets you schedule a periodic sync with a specific account, authority, and extras at the given frequency.</li>
+</ul>
+
+<h3>New manifest elements and attributes</h3>
+
+<ul>
+<li>For specifying the application's preferred install location (see <a href="#install-loc">App Installation on External Storage Media</a>, above):
+
+<ul>
+  <li>New <code>android:installLocation</code> attribute of the <code>&lt;manifest&gt;</code> element. Specifies the default install location defined by an application.</li>
+</ul>
+</li>
+
+<li>For managing user data backup (see <a href="#backup-manager">Backup manager</a>, above, for more information):
