            Toast.makeText(getBaseContext(), "Please check your internet and try again!", Toast.LENGTH_SHORT).show();

    }

Answer 1

It's because your else can't be reached

String userLocation = mLatitude + ","
            + mLongitude ;

    if(userLocation!=null){
       ...
    }else{
       ...
    }

userLocation will never be null
