I implemented FCM push notification in Android App.
I got all notification JSON in the data payload. I “not added” the’notification’ tag on the api. Therefore, in all states (foreground/ In the background/killed), I only get notifications in the data payload.

It is suitable for non-customized OS phones, such as Moto, Google, etc., the application is Foreground in all states /Background/Killed. But the problem is that when I test on a phone with a custom operating system such as Oppo, Vivo, or MIUI, the notification is only when the app is in the foreground or When it arrives in the background (the application is in memory), the application is “killed” when it does not arrive/appears (not in memory).

What should I do?

Anyway, thank you for your time.

I found a solution to this problem. Write a custom service for your application, which runs continuously in the background and writes to a broadcast receiver, In order to restart the service after the service is terminated. This works fine for me. I tested this on Vivo, Oppo, Redmi phones. This is working!

My service code is as follows-

public class MyService extends Service
{

private static final String TAG = "MyService";


@Override
public void onStart(Intent intent, int startId)
{
 // TODO Auto- generated method stub
 super.onStart(intent, startId);
}

@Override
public boolean onUnbind(Intent intent) {
 return super. onUnbind(intent);
}


@Override
public void onCreate()
{
 super.onCreate();
}

@Override
public int onStartCommand(Intent intent, int flags, int startId)
{
 //call to onTaskRemoved
 onTaskRemoved( intent);
 //return super.onStartCommand(intent, flags, startId);
 Toast.makeText(this, "Service Started!", Toast.LENGTH_SHORT).show();
 
 return START_NOT_STICKY;
}

@Nullable
@Override
public IBinder onBind(Intent intent)
{
 return null ;
}
@Override
public void onDestroy()
{
 Toast.makeText(this, "Service Destroyed!", Toast.LENGTH_SHORT).show();
 Intent intent = new Intent("com.myapp.startservice");
 //Intent intent = new Intent("android.intent.action.BOOT_COMPLETED");
 intent.putExtra("yourvalue ", "torestore");
 sendBroadcast(intent);
 super.onDestroy();

}



@Override public void onTaskRemoved(Intent rootIntent)
{
 Log.e("onTaskRemoved", "Called!");

 //thread = new Thread(this) ;
