Issue with repeated onEvent calls with FileObserver service

Question

Well, I seem to have the opposite problem of most FileObserver posts! Instead of onEvent never being called, mine is being called about 50 times . . . I must have set something up wrong but I'm running out of ideas. Can anyone see what I might have done wrong here?

FileObserverService:

import android.app.Service;
import android.content.Intent;
import android.os.FileObserver;
import android.os.IBinder;
import android.util.Log;

//public class FileObserverService {
public class FileObserverService extends Service{

    private FileObserver mFileObserver;
    int count = 0;

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        Log.i("Service", "OBS Service - On Start");
//        if((intent.hasExtra(INTENT_EXTRA_FILEPATH))) // we store the path of directory inside the intent that starts the service
//            mFileObserver = new FileObserver(intent.getStringExtra(INTENT_EXTRA_FILEPATH)) {
        if((intent.hasExtra("filepath"))) // we store the path of directory inside the intent that starts the service
            mFileObserver = new FileObserver(intent.getStringExtra("filepath")) {
                @Override
                public void onEvent(int event, String path) {
                    // If an event happens we can do stuff inside here
                    // for example we can send a broadcast message with the event-id
                    //Log.d("FILEOBSERVER_EVENT", "Event with id " + Integer.toHexString(event) + " happened"); // event identifies the occured Event in hex

                    switch(event){
                        case FileObserver.CREATE:
                            Log.d("OBS", "CREATE:" + path + count);
                            break;
                        case FileObserver.DELETE:
                            Log.d("OBS", "DELETE:" + path + count);
                            break;
                        case FileObserver.DELETE_SELF:
                            Log.d("OBS", "DELETE_SELF:" + path + count);
                            break;
                        case FileObserver.MODIFY:
                            Log.d("OBS", "MODIFY:" + path + count);
                            break;
                        case FileObserver.MOVED_FROM:
                            Log.d("OBS", "MOVED_FROM:"  + path + count);
                            break;
                        case FileObserver.MOVED_TO:
                            Log.d("OBS", "MOVED_TO:" + path + count);
                            break;
                        case FileObserver.MOVE_SELF:
                            Log.d("OBS", "MOVE_SELF:" + path + count);
                            break;
                        default:
                            // just ignore
                            break;
                    }
                    count += 1;
                }
            };
        mFileObserver.startWatching(); // The FileObserver starts watching
        return Service.START_NOT_STICKY;
    }

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

    @Override
    public IBinder onBind(Intent intent) {
        //TODO for communication return IBinder implementation
        return null;
    }
}

MainActivity:

public void ObsTapped(View view){
        Log.i("OnClick", "ObsTapped");

        //Insert code to observe change in file
        Intent intent = new Intent(this, FileObserverService.class);
        //intent.putExtra(INTENT_EXTRA_FILEPATH, "YOUR_FILEPATH");
        intent.putExtra("filepath", "/storage/emulated/0/Pictures/filename.jpeg");
        this.startService(intent);

        //startService(new Intent(getBaseContext(), FileObserverService.class));
    }

Below is a screenshot of the logs (the count goes up to null52 but it skipped null1 and null2):

Any idea what the issue could be?
