Android Java Service is started multiple times

I want to startService only once when I log in into my app and stop this service when I close app or log out. I want my service work for 2 min and for this I use a Handler.

This is my service:

public class Sendrer extends Service {

    public static boolean running = false;
    private Timer timer = new Timer();
    private SendPhotoTask asyncSender;
    private Context context;
    private SharedPreferences sp;
    private SharedPreferences.Editor editor;

    public static String convertStreamToString(java.io.InputStream is) {
        java.util.Scanner s = new java.util.Scanner(is).useDelimiter("\\A");
        return s.hasNext() ? s.next() : "";
    }

    @Override
    public void onCreate() {
        super.onCreate();
        context = getApplicationContext();
        sp = getSharedPreferences("pfref", Activity.MODE_PRIVATE);
        editor = sp.edit();
        Gson gson = new Gson();
        List<File> productFromShared = new ArrayList<>();
        SharedPreferences sharedPref = getApplicationContext().getSharedPreferences("TAG", Context.MODE_PRIVATE);
        String jsonPreferences = sharedPref.getString("TAG", "");

        Type type = new TypeToken<List<File>>() {
        }.getType();
        productFromShared = gson.fromJson(jsonPreferences, type);
        MainActivity.photoListSend = null;
        MainActivity.photoListSend = new ArrayList<>();
        if (productFromShared != null)
            MainActivity.photoListSend.addAll(productFromShared);
        Log.e("tworzenie serwisu ", "tworzenie");
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        Log.e("Dziełanie serwisu ", "Dziełanie");

        if (!running) {
            running = true;
            Handler handler = new Handler();
            handler.postDelayed(new Runnable() {
                @Override
                public void run() {
                    asyncSender = new SendPhotoTask();
                    asyncSender.execute();
                }
            }, 1000 * 60 * 2);
        }

        return START_STICKY;
    }

    @Override
    public void onDestroy() {
        if (running) {
            timer.cancel();
            asyncSender = new SendPhotoTask();
            asyncSender.cancel(true);
            running = false;
        }
        Log.e("service ", "nie działa");
        super.onDestroy();
    }

    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    public boolean isMyServiceRunning(Class<?> serviceClass) {
        ActivityManager manager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
        for (ActivityManager.RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {
            if (serviceClass.getName().equals(service.service.getClassName())) {
                return true;
            }
        }
        return false;
    }

    class SendPhotoTask extends AsyncTask<String, Void, String> {

        @Override
        protected String doInBackground(String... strings) {
            running = true;

Sometimes I start a service multiple times... And I want to that service works every 5 minutes

Refer this link for more help https://developer.android.com/guide/components/services.html

I think you are sending photo inside service than you should use IntentService instead of Service. IntentService will be destroyed after your task finish.

In service onStartCommand() call every time when you start service and if you dont want to run your service longer than return START_NOT_STICKY

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

If Your task is completed than call inside onDestroy() method stopSelf(). stopSelf method stop your service.

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