 */
public class PackageRemovedBroadcastReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Log.i("CDH", "應用解除安裝廣播");
Log.i("CDH", "包名:"+intent.getDataString());
Log.i("CDH", "使用者ID:"+intent.getIntExtra(Intent.EXTRA_UID, 0));
Log.i("CDH", "整個應用被解除安裝？:"+intent.getBooleanExtra(Intent.EXTRA_DATA_REMOVED, false));
Log.i("CDH", "重新安裝應用？:"+intent.getBooleanExtra(Intent.EXTRA_REPLACING, false));
}
}

<receiver android:name=".PackageRemovedBroadcastReceiver">
<intent-filter>
<action android:name="android.intent.action.PACKAGE_REMOVED"/>
        <data android:scheme="package"/>
</intent-filter>
</receiver>
