I am making an android game, but however, the game is functioning like it should, but i am experiencing some performance issues. I think it has something to do with the sound. Cause each time i touch the screen, it makes a sound. I am using the standard MediaPlayer. The method is onTouchEvent() and onPlaySound1(). Could you please help me with an alternate solution for playing the sound? Thank you so much in advance! It would be nice if you also came up with some suggestions on how i can improve my code. Take a look at my code here:
