Check perrmision (gps) need stop function

I need set gps in my Android application. But funcion requestLocationUpdates required check perrmision in this way:

    locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
    if(ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this,
            Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED)
    {
        ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, REQUEST_LOCATION);
        return;
    }
    locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this);

If i remove return (from if) app crash. If i put return function requestLocationUpdates will not be called!

How fix it?

You must not call requestLocationUpdates just after requestPermissions.

requestPermissions is an asynchronous call, "this" (your activity) is your listener

You have to implement in your activity:

 @Override
 public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
      //check if all the grantResult are equal to PackageManager.PERMISSION_GRANTED
 }

In that fonction check if the permission is accepted and if TRUE, then call your requestLocationUpdates.
