Hello,
I am trying to make an app that simply plays an mp3 file when you
click on a button. I've based my code off the API Demos from the
android website, and I've been scouring various Android developer
boards but all the solutions are still resulting in the same problem.
When you click on the button this code should be executed:
private void playAudio(Integer media){
MediaPlayer m = MediaPlayer.create(this, R.raw.b);
m.start();
}
When the program gets executed and I click on the button the program
crashes. All I've been able to determine from the stack trace is
that:
1 - The resource file cannot be found
or
2 - I am not able to open the file descriptor for some reason (it's
compressed?)
Here is the stack trace I am getting from logcat:
E/AndroidRuntime( 1425): Uncaught handler: thread main exiting due to
