Android foreground service consistently throws "java.lang.IllegalArgumentException: Service not registered" exception

Question

My project requires an android foreground service to run continuously (even after the application is destroyed). To this effect I have the following code snippets:

build.gradle

implementation fileTree(dir: 'libs', include: ['*.jar'])
//noinspection GradleCompatible
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'

implementation 'com.google.android.gms:play-services-places:16.0.0'
implementation 'com.google.android.libraries.places:places:1.1.0'
implementation 'com.google.android.gms:play-services-location:16.0.0'
testImplementation 'junit:junit:4.12'

MainActivity.java

@Override
public void onCreate() {
    Intent intent = new Intent(getApplicationContext(), MyService.class);
    if (!isMyServiceRunning(MyService.class, MainActivity.this)) {
        intent.setAction(MYConstants.ACTION_START_GPS_SERVICE);
        intent.setAction(MyConstants.ACTION_START_GPS_SERVICE);
        startService(intent);
        Log.i(TAG, "MyService call made.");
    }
}

MyService.java

public class MyService extends Service {
       @Override
       public void onCreate() {
           super.onCreate();
           if (Build.VERSION.SDK_INT > Build.VERSION_CODES.O) {
               startServiceWithNotification();
           } else{
               startForeground(9999, new Notification());
           }
       }

       @Override
       public int onStartCommand(Intent intent, int flags, int startId) {
            super.onStartCommand(intent, flags, startId);
            return START_STICKY;
       }

       @Override
       public void onTaskRemoved(Intent rootIntent){
          stopMyService();
          Intent broadcastIntent = new Intent(this, MyBroadcastReceiver.class);
          sendBroadcast(broadcastIntent);
       }

       @Override
       public void onDestroy() {
           stopMyService();
           super.onDestroy();
      }

      @Override
      public IBinder onBind(Intent intent) {
           // Used only in case of bound services.
           return null;
     }

     void stopMyService() {
          stopForeground(true);
          stopSelf();
     }

     @RequiresApi(Build.VERSION_CODES.O)
     void startServiceWithNotification() {
        String channelId = "com.mypackage.myapp";
        String channelName = "Your Service";

        NotificationChannel chan;

        chan = new NotificationChannel(channelId, channelName, NotificationManager.IMPORTANCE_NONE);
        chan.setLightColor(Color.BLUE);
        chan.setLockscreenVisibility(Notification.VISIBILITY_PRIVATE);
        NotificationManager mNotificationManager = (NotificationManager) 
               getSystemService(Context.NOTIFICATION_SERVICE);
        mNotificationManager.createNotificationChannel(chan);


        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, 
              channelId);

        Notification notification = notificationBuilder.setOngoing(true)
            .setSmallIcon(R.drawable.ic_launcher_foreground)
            .setContentTitle("App is running in background")
            .setPriority(NotificationManager.IMPORTANCE_MIN)
            .setCategory(Notification.CATEGORY_SERVICE)
            .build();
        startForeground(10000, notification);
    }
}

MyBroadcastReceiver.java

@Override
public void onReceive(Context context, Intent intent) {
    Intent intent =  new Intent(context, MyService.class);
    intent.setAction(MYConstants.ACTION_START_GPS_SERVICE);
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        context.startForegroundService(intent);
        Log.i(TAG, "MyService call made.");
    } else {
        context.startService(intent);
    }
}

This Application is working as expected, the foreground service runs fine doing what it is intended to do even after the app is destroyed, but I consistently see a Warning as an IllegalArgumentException while running the application. The exception is attached below:

Can someone help me out in understanding why this exception is consistently being thrown and how can I resolve this??

Answer 1

As suggested by @CommonsWare in the comments above, the exceptions observed here are being logged by Play Services which is quite common and isn't a consequence of the application. Unless the exceptions are causing serious problems (such as the app crashing), such exceptions must not be considered as a pain point.
