Android MP3: java.io.FileNotFoundException: This file can not be opened as a file descriptor; it is probably compressed

Question

I am trying to play a custom sound res/raw/notification.mp3. It is ~91KB.

Here is my code

MediaPlayer.create(context, R.raw.notification).start();

Here is my error

Same thing happens to an unrelated WAV file so it is probably not the MP3's problem.

What might be wrong? Should I uncompress the WAV/MP3? How?

Answer 1

It turns out to be a problem with the NetBeans generated build scripts. I did a tutorial from scratch and it failed in NetBeans and worked in Eclipse. I suppose I will finally learn Eclipse. It is something I have been wanting to do at least as a comparison in hopes it would be less buggy, but I have not had the time. Well necessity is going to gave me the time now.
