Backing up persistent data +this way provides a restore point for the app on most devices running Android 2.2 or +higher. The backup service is <em>not</em> designed for synchronizing application data with other +clients or saving data that you'd like to access at random during the +application lifecycle.</p> + +<p>The Android Backup Service offered by Google provides a backup +transport on most devices that include Google Play Store and backs up your app data to Google +servers. The backup transport may differ +from device to device and which backup transport is available on any device is +transparent to your application.</p> + +<p>In order to use Android Backup Service, you must <a href="{@docRoot}google/backup/signup.html" +>register your app</a> with the service to receive a key that you must +include in your Android manifest.</p> + +<p class="note"><strong>Note:</strong> Registering your application with Android Backup +Service does not guarantee that it will always back up data using this service +from Google. If you support +data backup in your application, then it will back up using whichever transport is enabled +on the device. Registering with Android Backup Service allows your application to back up +when the backup transport on the device is provided by Android Backup Service.</p> + +<p>For more information about how data backup works on Android and how to use it in your app, +read the <a href="{@docRoot}guide/topics/data/backup.html">Data Backup</a> guide.</p> + + + +<h2>Adding the Backup Service Key to the Manifest</h2> + +<p>Once you <a href="{@docRoot}google/backup/signup.html" +>register your app</a>, you'll receive a Backup Service Key, +which you must include in your Android manifest file with the following syntax:</p> + +<pre class="prettyprint"> +<application> + <meta-data android:name="com.google.android.backup.api_key" + android:value="<em>your_backup_service_key</em>" /> + ... +</application> +</pre> + +<p>Insert your Backup Service Key in the <code>android:value</code> attribute and place the +<code><meta-data></code> element inside your Android manifest's +<code><application></code> element.</p> + +<p>When a device that uses Android Backup Service runs your application, +the system verifies that your Backup Service Key is valid and Android Backup Service saves the +user's data to Google servers using the primary Google account on the device.</p> + +<p>If your application +does not provide a valid Backup Service Key, then backup will not occur. If the device does not +provide backup using Android Backup Service, then the <code><meta-data></code> element and +Backup Service Key are ignored—your application will work normally, but will either back up +data using a different backup transport or not perform backup at all. Either +way, your application is unaware of what transport is used, if at all, and otherwise +operates normally.</p> + +<p>For more information about how to provide data backup in your Android application, see the <a +href="{@docRoot}guide/topics/data/backup.html">Data Backup</a> guide.</p> + + +<h2>User Privacy</h2> + +<p>At Google, we are keenly aware of the trust users place in us and our responsibility to protect +users' privacy. Google securely transmits backup data to and from Google servers in order to provide +backup and restore features. Google treats this data as personal information in accordance with +Google's <a href="http://www.google.com/privacypolicy.html">Privacy Policy</a>.</p> + +<p>In addition, users can disable data backup functionality through the Android +system's privacy settings. When a user disables backup, Android Backup Service deletes all saved +backup data. A user can re-enable backup on the device, but Android Backup Service will not restore +any previously deleted data.</p> |
