如何在我的Android应用程序的res / raw文件夹中播放mp3？

I have a small (200kb) mp3 in the res/raw folder of my android app. I am trying to run it in an emulator from Eclipse. It is recognized as a resource in the R file but when I try to prepare/start, my activity crashes! Was there something else I needed to change, perhaps in the manifest?
