I have tried threading which proves nothing. I have even tried making a new
method that threads the mediaplayer's "start();" method like so:
somewhere in the code:
MediaPlayer mp = MediaPlayer.create(this, R.raw.good);
//mp.release();
playSound(mp);
then:
private void playSound(final MediaPlayer mp) {
new Thread(new Runnable() {
public void run() {
try {
mp.prepare();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
mp.start();
}
}).start();
}
The same loop, the same mp3, the same evrything, but after 7 loops - it
Force Closes.
Now I'm just lost...
