<em>API Level:</em> <strong>{@sdkPlatformApiLevel}</strong></p>
|
|
|
|
<p>Android {@sdkPlatformVersion} is a {@sdkPlatformMajorMinor} platform release
|
|
deployable to Android-powered handsets starting in December 2009.
|
|
This release includes minor API
|
|
changes, bug fixes and framework behavioral changes. For information on changes
|
|
and fixes, see the <a href="#api">Framework API</a> section.</p>
|
|
|
|
<p>For developers, the Android {@sdkPlatformVersion} platform is available as a
|
|
downloadable component for the Android SDK. The downloadable platform includes a
|
|
fully compliant Android library and system image, as well as a set of emulator
|
|
skins, sample applications, and more. The downloadable platform
|
|
includes no external libraries. </p>
|
|
|
|
<p>To get started developing or testing against the Android
|
|
{@sdkPlatformVersion} platform, use the Android SDK and AVD Manager tool to
|
|
download the platform into your Android 1.6 or later SDK. For more information,
|
|
see <a href="{@docRoot}sdk/adding-components.html">Adding SDK
|

<h3 id="ant">Ant Support</h3>
|
|
|
|
<ul>
|
|
<li>Debug- and release-mode application signing. Release-mode signing includes integrated support for <code>zipalign</code> optimization. For more information, see <a href="{@docRoot}guide/publishing/app-signing.html#releasecompile">Signing Your Applications</a>.</li>

|
<h2 id="api">Framework API</h2>
|
|
|
|
<p>The sections below provide information about changes made to the application
|
|
framework API provided by the Android {@sdkPlatformVersion} platform. Note,
|
|
however, that Android 2.0.1 is a minor release to Android 2.0, so for more
|
|
information about the changes made to in Android 2.0, please refer to the
|
|
<a href="{@docRoot}sdk/android-2.0.html#api">Android 2.0 version notes</a>.</p>
|
|
|
|
|
|
<h3 id="api-level">API level</h3>
|
|
|
|
<p>The Android {@sdkPlatformVersion} platform delivers an updated version of the framework
|
|
API. The Android {@sdkPlatformVersion} API
|
|
is assigned an integer identifier — <strong>{@sdkPlatformApiLevel}</strong> — 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 attributes of the <code><uses-sdk></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>
|
|
|
|
|
|
<h3 id="api-changes">API changes summary</h3>
|
|
|
|
<p>The following is a summary of changes to the framework APIs.</p>
|
|
|
|
<ul>
|
|
<li>New {@code quickContactBadgeStyle*} attributes that let
|
|
applications apply necessary styles to the {@link
|
|
android.widget.QuickContactBadge} widget.</li>
|
|
|
|
<li>Remove support for the {@link
|
|
android.content.Intent#ACTION_CONFIGURATION_CHANGED} broadcast when declared as
|
|
a filter in the manifest. To receive this broadcast, an application must
|
|
do so from the application at run-time, with {@link
|
|
android.content.Context#registerReceiver(BroadcastReceiver, IntentFilter)}.</li>
|
|
</ul>
|
|
|
|
<h3 id="behavior-changes">Behavior changes</h3>
|
|
|
|
<p>The following is a summary of changes that affect the behavior of some
|
|
framework APIs but do not add or remove API functionality.</p>
|
|
|
|
<h4>Bluetooth</h4>
|
|
|
|
<p>Changes to the values returned by {@link
|
|
android.bluetooth.BluetoothAdapter#ACTION_REQUEST_ENABLE} and
|
|
{@link android.bluetooth.BluetoothAdapter#ACTION_REQUEST_DISCOVERABLE}:</p>
|
|
|
|
<ul>
|
|
<li>{@link android.bluetooth.BluetoothAdapter#ACTION_REQUEST_ENABLE} now
|
|
returns {@link android.app.Activity#RESULT_OK} if Bluetooth was successfully
|
|
enabled and {@link android.app.Activity#RESULT_CANCELED} if the user rejected
|
|
the request to enable Bluetooth, rather than 0 and -1 (or -2),
|
|
respectively.</li>
|
|
|
|
<li>{@link android.bluetooth.BluetoothAdapter#ACTION_REQUEST_DISCOVERABLE}
|
|
now returns {@link android.app.Activity#RESULT_CANCELED} if the user rejected
|
|
the request to enable discoverability or if Bluetooth is not enabled, rather
|
|
than -1 and -2, respectively.</li>
|
|
</ul>
|
|
|
|
<h4>Contacts</h4>
|
|
|
|
<p>The {@link android.content.Intent#ACTION_INSERT} Intent now returns {@link
|
|
android.app.Activity#RESULT_CANCELED} in cases where the contact was not
|
|
persisted (for example, if the save was trimmed to a no-op).</p>
|
|
|
|
|
|
<h3 id="bug-fixes">Bug fixes</h3>
|
|
|
|
<p>The following is a summary of bug fixes that affect some framework APIs.</p>
|
|
|
|
<h4>Resources</h4>
|
|
|
|
<p>The framework now correctly selects application resources in project
|
|
folders that use the API Level qualifier. For example, {@code drawable-v4/} is a
|
|
folder of drawable resources for API Level 4 (or higher) devices. This version
|
|
matching did not work properly and has been fixed.</p>
|
|
|
|
<h4>Contacts</h4>
|
|
|
|
<p>The {@link android.content.Intent#ACTION_INSERT} Intent now returns the
|
|
appropriate kind of URI when the request is made using the (now
|
|
deprecated) {@link android.provider.Contacts} APIs.</p>
|
|
|
|
<h4>Other Framework fixes</h4>
|
|
|
|
<ul>
|
|
<li>{@link android.app.Activity#getCallingPackage()} now properly reports the
|
|
package name, rather than the process name.</li>
|
|
</ul>
|
|
|
|
|

API Level 5, see the <a
