I'm a bit busy to do a test myself, but on a quick glance this line in
the stacktrace seems interesting:
E/AndroidRuntime( 1425): Caused by: java.io.FileNotFoundException:
This file can not be opened as a file descriptor; it is probably
compressed
Try converting your mp3 file to a raw .wav format and loading that
from your res/raw directory instead...
If this works, you may find that there is some issue playing
compressed formats directly from the APK file, and that you need to
read them some other way (e.g. copy them to the SD card before
playback). This might also be a bug.

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:
