Making Soundboard...MediaPlayer help?

[UNEXPECTED62]

Hi,

I have been working on a soundboard for some time now. This is my first app for Android, but I have been programming Java at an educational level (3rd year college student).

Before I go too far, would Android's MediaPlayer class be a good thing to use for making a soundboard? Or should a different approach be taken?

Now that that is out of the way, here is the code for one of my buttons.

public class Soundboard extends Activity 
{
          MediaPlayer theme;
          Button themeSongButton;

          private boolean hasBeenRun = false;
        
        @Override
         public void onCreate(Bundle savedInstanceState) 
        {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.soundboard);
        
        
        theme = MediaPlayer.create(Soundboard.this,R.raw.theme);

         /*
         * Theme song button
         */
        
        themeSongButton.setOnClickListener(new OnClickListener()
        {
            public void onClick(View arg0)
            {
                
                if (hasBeenRun)
                {
                    stopPlayer();
                
                    try 
                    {
                        theme.prepare();
                    } 
                    catch (IllegalStateException e) 
                    {
                    
                    } catch (IOException e) 
                    {
                        
                    }
                }
                theme.start();
                if (!hasBeenRun)
                {
                    hasBeenRun = true;
                }
                theme.setOnCompletionListener(new OnCompletionListener()
                {
                    public void onCompletion(MediaPlayer mp) 
                    {
                        try 
                        {
                            mp.prepare();
                        } 
                        catch (IllegalStateException e) 
                        {
                            
                        }                 
                        catch(IOException ioe)
                        {
                            
                        }
                    }
                });
                                        
            }
        });

And here is that method stopPlayer() that is called above.

public void stopPlayer()
    {
        if(theme.isPlaying())
        {
            theme.stop();
        }
                
    }

I am new to coding forums, so I'm sure the etiquette for posting code. I omitted all of the other buttons and sounds, as it is literally verbatim the above, sans a different media player object and button with it's listener, etc. The stopPlayer() method also actually includes all the buttons and stops them if they're playing. This is so if a sound is still going and you hit a new button, it will cut the sound off and start the new one.

The bug I am running into is, after so many button presses, no sounds will play anymore. I don't get a force close, they just stop responding. I think I am somehow getting in the wrong state for the MediaPlayer, but following the StateDiagram in the API I feel like I am correct.

Can anyone shed some light on this for me?
