TBD

• Initial import to github. I've added several ways to identify an android device.

Usage

To make use of the device identification you only need to add an DeviceIdentityProvider to your activity:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    ...

    identityProvider = DeviceIdentityProvider.getInstance(this);

    // force backup for new device immediately
    if (identityProvider.isNewDevice()) {
        BackupManager backupManager = new BackupManager(this);
        backupManager.dataChanged();
    }

    ...
}

If you want automatically backup your application data to android backup service you need to add some snippets to the applications manifest an an activity:

<application android:backupAgent="com.thomashaertel.device.backup.SimpleBackupAgent" android:allowBackup="true" ...>
    <meta-data android:name="com.google.android.backup.api_key" android:value="your-api-key" />
    ...
</application>

@Override
protected void onStop() {
    // allow backup authorized devices only
    if (identityProvider.isAuthorizedDevice()) {
        BackupManager backupManager = new BackupManager(this);
        backupManager.dataChanged();
    }

    super.onStop();
}
