mediaplayer error on soundboard app

Question

I have a soundboard app that calls that calls audio files when their button is pressed. However, after most of the buttons havebeen pressed and played, I start to get these mediaplayer errors. Does anyone know How to detect it and just restart or stop it completely from happening? Thanks for your time.

    for (Map.Entry<Integer, Integer> entry : map.entrySet()) {
        ImageButton button = (ImageButton) findViewById(entry.getKey());
        button.setOnClickListener(new View.OnClickListener() {

                try {

James has the right idea. You're creating too many MediaPlayer instances after a while, and running out of memory. A solution I posted previously was something to this effect:

public MediaPlayer mp;
public Resources res = getResources();

View.OnClickListener listener = new View.OnClickListener() {
    public void onClick(View v) {
        try {
            int sound = map.get(v.getId());
            AssetFileDescriptor afd = res.openRawResourceFd(sound);

            mp.reset();
            mp.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getLength());
            mp.prepare();
            mp.start();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

for(Map.Entry<Integer, Integer> entry : map.entrySet()) {
    ImageButton button = (ImageButton)findViewById(entry.getKey());
    button.setOnClickListener(listener);
}

This might not compile (I'm assuming your sound IDs are from the res/raw folder), but the idea is, just have ONE MediaPlayer instance, and whenever a button is clicked, reset that instance, set the data source to the corresponding FileDescriptor, prepare it, and start playback.
