For a summary of the API, see the +<a href="{@docRoot}sdk/android-2.3.3.html">Android 2.3.3 version notes</a>.</p> + + +<h2 id="openaccessory">Open Accessory Library</h3> + +<p><em>Open Accessory</em> is a new capability for integrating +connected peripherals with applications running on the platform. The capability +is based on a USB (Universal Serial Bus) stack built into the platform and an +API exposed to applications. Peripherals that attach to Android-powered devices +as accessories connect as USB hosts. </p> + +<p>Open Accessory is introduced in <a +href="{@docRoot}sdk/android-3.1.html#usb">Android 3.1</a> (API level 12), but is +made available to devices running Android 2.3.4 by means of an optional external +library, the Open Accessory Library. The library exposes a framework API that +lets applications discover, communicate with, and manage a variety of device +types connected over USB. It also provides the implementation of the API against +parts of the Android platform that are not directly exposed to applications in +Android 2.3.4.</p> + +<p>The Open Accessory Library is optional on any given device. Device +manufacturers may choose whether to include the Open Accessory Library in their +products or exclude it. The library is forward-compatible with Android 3.1, so +applications developed against Android 2.3.4 will run properly on devices +running Android 3.1, if those devices support USB accessories. </p> + +<p>The API provided by the Open Accessory Library is based on the Open Accessory +API provided in Android 3.1. In most areas, you can use the same techniques and +APIs. However, developing for the Open Accessory Library on Android 2.3.4 differs +from the standard USB API in these ways: + +<ul> +<li>Obtaining a {@link android.hardware.usb.UsbManager} object — To obtain +a {@link android.hardware.usb.UsbManager} object when using the add-on library, +use the helper method <code>getInstance()</code> rather than {@link +android.content.Context#getSystemService(java.lang.String) getSystemService()} +For example: + +<pre>UsbManager manager = UsbManager.getInstance(this);</pre></li> + +<li>Obtaining a {@link android.hardware.usb.UsbAccessory} from a filtered intent +— When you filter for a connected device or accessory with an intent +filter, the {@link android.hardware.usb.UsbAccessory} object is contained +inside the intent that is passed to your application. If you are using the +add-on library, you can get the {@link android.hardware.usb.UsbAccessory} object +in the following manner: + +<pre>UsbAccessory accessory = UsbManager.getAccessory(intent)</pre></li> + +<li>No USB host support — Android 2.3.4 and the Open Accessory Library do +not support USB host mode (for example, through {@link +android.hardware.usb.UsbDevice}), although USB host mode is supported in Android +3.1. An Android-powered device running Android 2.3.4 can not function as a USB +host. The library enables the Android-powered device to function as +a peripheral only, with the connected accessory functioning as USB host +(through {@link android.hardware.usb.UsbAccessory}).</li> +</ul> + +<p>To develop apps using the Open Accessory Library, you need:</p> + +<ul> +<li>The latest version of the Android SDK tools</li> +<li>The latest version of the Google APIs add-on, which includes the library +itself (for linking)</li> +<li>An actual hardware device running Android 2.3.4 (or Android 3.1) with USB +accessories support, for runtime testing against connected devices</li> +</ul> + +<p>For a full discussion of how to develop applications that interact with USB +accessories, please see the related <a +href="{@docRoot}guide/topics/usb/index.html">developer documentation</a>.</p> + +<p>Additionally, developers can request filtering on Android Market, such that +their applications are not available to users whose devices do not provide the +appropriate accessory support. To request filtering, add the element below +to the application manifest:</p> + +<pre><uses-feature + android:name="android.hardware.usb.accessory" + android:required="true"></pre> + + +<h2 id="api-level">API Level</h2> + +<p>The Android 2.3.4 platform does <em>not</em> increment the API level — +it uses the same API level as Android 2.3.3, API level 10. + +<p>To use APIs introduced in API level 10 in your application, +you need compile the application against the Android library that is provided in +the latest version of the Google APIs Add-On, which also includes the Open +Accessory Library.</p> + +<p>Depending on your needs, you might +also need to add an <code>android:minSdkVersion="{@sdkPlatformApiLevel}"</code> +attribute to the <code><uses-sdk></code> element in the application's +manifest. If your application is designed to run only on Android 2.3.3 and higher, +declaring the attribute prevents the application from being installed on earlier +versions of the platform.</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="apps">Built-in Applications</h2> + +<p>The system image included in the downloadable platform provides these +built-in applications:</p> + +<table style="border:0;padding-bottom:0;margin-bottom:0;"> +<tr> +<td style="border:0;padding-bottom:0;margin-bottom:0;"> +<ul> +<li>Browser</li> +<li>Calculator</li> +<li>Camera</li> +<li>Clock</li> +<li>Contacts</li> +<li>Cusom Locale</li> +<li>Dev Tools</li> +<li>Downloads</li> +<li>Email</li> +</ul> +</td> +<td style="border:0;padding-bottom:0;margin-bottom:0;padding-left:5em;"> +<ul> +<li>Gallery</li> +<li>IMEs for Japanese, Chinese, and Latin text input</li> +<li>Messaging</li> +<li>Music</li> +<li>Phone</li> +<li>Search</li> +<li>Settings</li> +<li>Spare Parts (developer app)</li> +<li>Speech Recorder</li> +</ul> +</td> +</tr> +</table> + + +<h2 id="locs" style="margin-top:.75em;">Locales</h2> + +<p>The system image included in the downloadable SDK platform provides a variety of +built-in locales.
