I slapped together a simple test application that has a button, and makes a noise when the user clicks on it. Here are it's method:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    Button b = (Button)findViewById(R.id.easy);
    b.setOnClickListener(this);
}

public void onClick(View v) {
    MediaPlayer mp = MediaPlayer.create(this, R.raw.easy);
    mp.start();
    while(true) {
        if (!mp.isPlaying()) {
            mp.release();
            break;
        }
    }
}

My question is, why is onCreate acting like it's in a while loop? I can click on the button whenever, and it makes the sound. I might think it was just a property of listeners, but the Button object wasn't a member variable. I thought that Android would just go through onCreate onse, and proceed onto the next lifecycle method.

Also, I know that my current way of seeing if the sound is playing is crap...I'll get to that later. :)

Thank you.
