android media player delay

I am making a game for android which needs to play a small beep whenever a user touches a certain object.

To do this I have this simple code to create the media player. beep is a small .ogg file of ~1.5 sec length.

MediaPlayer mp = MediaPlayer.create(getContext(), R.raw.beep);
mp.setVolume(0.5f, 0.5f);

and use it like this 

mp.start();

The problem I am having is that my game uses the android canvas, and the thread which draws to the canvas also calls mp.start(). I have discovered that playing the sound is taking quite a lot of time, and it is very varied in how long it takes. Sometimes 1ms, sometimes 15ms. This appears to be causing my game to noticeably lag a little bit, as the android canvas is pretty slow anyway.

I've had a look at the logs and I don't appear to having garbage collection causing the delay. I'm wondering if anyone can give me some advice to reduce this delay

EDIT - I've just discovered that MediaPlayer is designed for longer sound files, and SoundPool is better for shorter audio files. However, I load the file into the mediaPlayer only once, so I don't see how it should make any difference. I will test it out though

sorry for my english

Use SoundPool instead of MediaPlayer cause MediaPlayer need releasing memory after each call or call method mp.release() after each call of player
