Android アプリに GCM を使用してプッシュ通知を実装しました。現在、登録されているすべてのデバイスの通知を取得しています。しかし、いつ自分のデバイスを登録解除する必要があるのか 混乱しています。

これが私の主な活動です。GCM.Unregister(this) を呼び出す場所を教えてください。誰かがアプリをアンインストールすると、その登録 ID に対して GCM サーバーが応答NotRegisteredをサードパーティ サーバーに送信するためです。そのことを念頭に置いて、デバイスの登録を解除することを考えていました。
GCMIntentService.java
public class GCMIntentService extends GCMBaseIntentService {
private static final String TAG = "GCMIntentService";
String installregids = "";
String uninstallregids = "";
DemoActivity dact= new DemoActivity();
public GCMIntentService() {
super(SENDER_ID);
}
@Override
protected void onRegistered(Context context, String registrationId) {
Log.i(TAG, "Device registered: regId = " + registrationId);
this.installregids=registrationId;
try {
dact.new MovieDetails().execute(registrationId);
GCMRegistrar.setRegisteredOnServer(context, true);
}
catch (Exception e) {
e.printStackTrace();
}
}
@Override
protected void onUnregistered(Context context, String registrationId) {
Log.i(TAG, "Device unregistered");
this.uninstallregids=registrationId;
try {
if (GCMRegistrar.isRegisteredOnServer(context)) {
// dact.new MessgaeDelete().execute(registrationId);
} else {
Log.i(TAG, "Ignoring unregister callback");
}
GCMRegistrar.setRegisteredOnServer(context, false);
}
catch (Exception e) {
e.printStackTrace();
}
}
@Override
protected void onMessage(Context context, Intent intent) {
Log.i(TAG, "Received message");
// String message = getString(R.string.gcm_message);
String message = intent.getExtras().getString("message");
Log.d("Message Received", message);
generateNotification(context, message);
}
}
@Override
protected boolean onRecoverableError(Context context, String errorId) {
// log message
Log.i(TAG, "Received recoverable error: " + errorId);
return super.onRecoverableError(context, errorId);
}
private static void generateNotification(Context context, String message) {
int icon = R.drawable.ic_stat_gcm;
long when = System.currentTimeMillis();
NotificationManager notificationManager = (NotificationManager)
context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(icon, message, when);
String title = context.getString(R.string.app_name);
Intent notificationIntent = new Intent(context, DemoActivity.class);
// set intent so it does not start a new activity
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent intent =
PendingIntent.getActivity(context, 0, notificationIntent, 0);
notification.setLatestEventInfo(context, title, message, intent);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(0, notification);
}
}
