Foreground Activities can use the API to register an NDEF -message that will get pushed to other NFC devices when they connect.</p> - -<p>Advanced tag dispatching now gives applications more control over how and -when they are launched, when an NFC tag is discovered. Previously, the platform -used a single-step intent dispatch to notify interested applications that a tag -was discovered. The platform now uses a four-step process that enables the -foreground application to take control of a tag event before it is passed to any -other applications (<code>android.nfc.NfcAdapter.enableForegroundDispatch()</code>). - -The new dispatch process also lets apps listen for specific tag content and -tag technologies, based on two new intent actions — -<code>android.nfc.action.NDEF_DISCOVERED</code> and -<code>android.nfc.action.TECH_DISCOVERED</code>.</p> - -<p>The NFC API is available in the {@link android.nfc} and -{@link android.nfc.tech} packages. The key classes are: </p> - -<ul> -<li>{@link android.nfc.NfcAdapter}, which represents the NFC hardware on the device.</li> -<li>{@link android.nfc.NdefMessage}, which represents an NDEF data message, -the standard format in which "records" carrying data are transmitted between -devices and tags. An NDEF message certain many NDEF records of different types. -Applications can receive these messages from -{@link android.nfc.NfcAdapter#ACTION_NDEF_DISCOVERED NDEF_DISCOVERED}, -{@link android.nfc.NfcAdapter#ACTION_TECH_DISCOVERED TECH_DISCOVERED}, or -{@link android.nfc.NfcAdapter#ACTION_TAG_DISCOVERED TAG_DISCOVERED} Intents.</li> -<li>{@link android.nfc.NdefRecord}, delivered in an -{@link android.nfc.NdefMessage}, which describes the type of data being shared -and carries the data itself.</li> -<li>{@link android.nfc.Tag}, which represents a tag scanned by the device. -Multiple types of tags are supported, based on the underlying tag -technology.</li> -<li>{@link android.nfc.tech.TagTechnology}, an interface that gives applications -access to tag properties and I/O operations based on the technologies present -in the tag. For a full list of tag technologies supported in Android 2.3.3, see -{@link android.nfc.tech}.</li> -</ul> - -<p>NFC communication relies on wireless technology in the device hardware, and -is not present in all Android devices. Android devices that do not support -NFC will return a null object when -{@link android.nfc.NfcAdapter#getDefaultAdapter(android.content.Context) -getDefaultAdapter(Context)} is called, and -<code>context.getPackageManager().hasSystemFeature(PackageManager.FEATURE_NFC)</code> -will return <code>false</code>. The NFC API is always present, however, regardless of -underlying hardware support.</p> - -<p>To use the NFC API, applications must request permission from the user by -declaring <code><uses-permission -android:name="android.permission.NFC"></code> in their manifest files.</p> - -<p>Additionally, developers can request filtering on Google Play, such that -their applications are not discoverable to users whose devices do not support -NFC. To request filtering, add -<code><uses-feature android:name="android.hardware.nfc" -android:required="true"></code> to the application's manifest.</p> - -<p class="note">To look at sample code for NFC, see -<a href="{@docRoot}resources/samples/NFCDemo/index.html">NFCDemo app</a>, <a href="{@docRoot}resources/samples/ApiDemos/src/com/example/android/apis/nfc/TechFilter.html">filtering by tag technology</a></li>, <a href="{@docRoot}resources/samples/ApiDemos/src/com/example/android/apis/nfc/ForegroundDispatch.html">using foreground dispatch</a>, and <a href="{@docRoot}resources/samples/ApiDemos/src/com/example/android/apis/nfc/ForegroundNdefPush.html">foreground NDEF push (P2P)</a>.</p> - -<h3 id="bluetooth">Bluetooth</h3> - -<p>Android 2.3.3 adds platform and API support for Bluetooth nonsecure socket -connections. This lets applications communicate with simple devices that may not -offer a UI for authentication. See -{@link android.bluetooth.BluetoothDevice#createInsecureRfcommSocketToServiceRecord(java.util.UUID)} and -{@link android.bluetooth.BluetoothAdapter#listenUsingInsecureRfcommWithServiceRecord(java.lang.String, java.util.UUID)} -for more information. </p> - -<h3 id="graphics">Graphics</h3> - -<ul> -<li>A new {@link android.graphics.BitmapRegionDecoder} class lets applications -decode a rectangle region from an image. The API is particularly useful when an -original image is large and and the application only need parts of the image. -</li> -<li>A new {@link -android.graphics.BitmapFactory.Options#inPreferQualityOverSpeed} field in {@link -android.graphics.BitmapFactory.Options} allows applications to use a more accurate -but slightly slower IDCT method in JPEG decode. This in turn improves the -quality of the reconstructed image.</li> -</ul> - - -<h3 id="media">Media framework</h3> - -<ul> -<li>A new {@link android.media.MediaMetadataRetriever} class provides a unified -interface for retrieving frame and metadata from an input media file.</li> -<li>{@link android.media.MediaRecorder.AudioEncoder} and {@link -android.media.MediaRecorder.OutputFormat} include new fields for specifying AMR -Wideband and AAC formats. </li> -</ul> - - -<h3 id="speech">Speech recognition</h3> - -<p>The speech-recognition API includes new constants to let you manage voice -search results in new ways. Although the new constants are not needed for normal -use of speech recognition, you could use them to offer a different view of voice -search results in your application. For information, see {@link -android.speech.RecognizerResultsIntent}.</p> - - -<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 — -<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 compile the application against the Android library that is provided in -the Android {@sdkPlatformVersion} SDK platform. 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 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.
