Gestern hat Google bei Google I / O das neue Benachrichtigungssystem vorgestellt, das auf der neuen Firebase basiert. Ich habe dieses neue FCM (Firebase Cloud Messaging) mit dem Beispiel auf Github ausprobiert.
Das Symbol der Benachrichtigung ist immer der ic_launcher, obwohl ich ein bestimmtes Drawable deklariert habe
Warum ? Hier unten der offizielle Code für die Bearbeitung der Nachricht
public class AppFirebaseMessagingService extends FirebaseMessagingService {
/**
* Called when message is received.
*
* @param remoteMessage Object representing the message received from Firebase Cloud Messaging.
*/
// [START receive_message]
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
// If the application is in the foreground handle both data and notification messages here.
// Also if you intend on generating your own notifications as a result of a received FCM
// message, here is where that should be initiated. See sendNotification method below.
sendNotification(remoteMessage);
}
// [END receive_message]
/**
* Create and show a simple notification containing the received FCM message.
*
* @param remoteMessage FCM RemoteMessage received.
*/
private void sendNotification(RemoteMessage remoteMessage) {
Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
PendingIntent.FLAG_ONE_SHOT);
Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
// this is a my insertion looking for a solution
int icon = Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP ? R.drawable.myicon: R.mipmap.myicon;
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(icon)
.setContentTitle(remoteMessage.getFrom())
.setContentText(remoteMessage.getNotification().getBody())
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}
}
