FCM Notification not working on some devices when application is killed or not in foreground

Question

Did some research on making FCM notification work some devices when the application is killed by the user(swiped away by the user from the app tray) or killed by the system OS but did not find any solution would appreciate if you can provide with solution or tell me what i am dong wrong. The notification is a data payload

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        // TODO: Handle FCM messages here.
        // 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.
        notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        String payload = "",notification_message = "", channelId ="", channelName="AAA", channelDescription="";
        Log.d(TAG, "From: " + remoteMessage.getFrom());
        String title = null, body = null;
        if(remoteMessage.getNotification() != null) {
            Log.d("REMOTE_DATA",remoteMessage.getNotification().getBody());
            title = remoteMessage.getNotification().getTitle();
            body = remoteMessage.getNotification().getBody();
        }

        if(remoteMessage.getData() != null) {
            if(remoteMessage.getData().get("title") != null) 
               title = remoteMessage.getData().get("title");

            if(remoteMessage.getData().get("message") != null) 
               body = remoteMessage.getData().get("message");

            if(remoteMessage.getData().get("channelName") != null) 
               channelName = remoteMessage.getData().get("channelName");
        }
    }

    //Setting up Notification channels for android O and above
    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
        Log.e(TAG, "onMessageReceived: => " + android.os.Build.VERSION.SDK_INT);

        if(notificationChannels.containsKey(channelName)) {
            JSONObject channelData = (JSONObject) notificationChannels.get(channelName);
            try {
                channelId = channelData.getString("channelId");
                channelName = channelData.getString("channelName");
                channelDescription = channelData.getString("channelDescription");
            } catch (JSONException e) {
                e.printStackTrace();
            }

            NotificationChannel notificationChannel = notificationManager.getNotificationChannel(channelId);
            if (notificationChannel == null)
                setupChannel(channelId, channelName, channelDescription);
        }
    }

    Log.d(TAG, "Notification Message Body: " + title);
    Log.d(TAG, "Notification Message Body: " + body);
    if(title != null && body != null) {
        apptivity_variable.createNotification(channelId,title, body);
        db.insertNotification(title, body, remoteMessage.getData().toString());
    }
}

This is somewhat related to your issue, it's just that Chinese-made phones are notorious for killing apps. Please read solutions here: https://dontkillmyapp.com/ — Zun, Jul 22 '19 at 12:01

Try registering another service to identify the app in the background to trigger the service

public class FirebaseBackgroundService extends BroadcastReceiver{

  private static final String TAG = "FirebaseService";

  @Override
  public void onReceive(Context context, Intent intent) {
    Log.d(TAG, "I'm in!!!");

    if (intent.getExtras() != null) {
      for (String key : intent.getExtras().keySet()) {
        Object value = intent.getExtras().get(key);
        Log.e("FirebaseDataReceiver", "Key: " + key + " Value: " + value);
        if(key.equalsIgnoreCase("gcm.notification.body") && value != null) {
          Bundle bundle = new Bundle();
          Intent backgroundIntent = new Intent(context, BackgroundSyncJobService.class);
          bundle.putString("push_message", value + "");
          backgroundIntent.putExtras(bundle);
          context.startService(backgroundIntent);
        }
      }
    }
  }
}

Also, don't forget to register it in your manifest.xml

<receiver android:exported="true" android:name=".FirebaseBackgroundService" android:permission="com.google.android.c2dm.permission.SEND">
            <intent-filter>
                <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            </intent-filter>
        </receiver>

Thanks for the time but I'm not sure it is going to get to this block of code... let me give it a try — Dolapo Olakanmi, Aug 28 '19 at 17:55

There are two different types of push messages priorities in FCM: normal priority and high priority. Only high priority pushes will wake your application up when it's in background and is the subject of Doze Mode restrictions. You can read more about it in this article

To make priority of your push message high, you have to add this section to the body of your push message:

"android":{"priority":"high"}

More information about push messages is available here

Thanks for your response but nothing has worked. before now, it works on some android devices i am sure of a Nokia phone when the application is in background or doze mode but not working on phones like tecno, huawei, xiaomi, etc. even after all you recommend me to do – Dolapo Olakanmi Jul 30 '19 at 15:38
Could you add an example of your push message? – Stanislav Shamilov Jul 30 '19 at 15:52
this is the pushMessage object example: {"to":"token","android":{"priority":"high"},"data":{"title":"titleName","body":"detail"},"notification":{"title":"titleName","body":"detail"}} – Dolapo Olakanmi Jul 30 '19 at 20:10
