Having a very strange issue, and it only happens when compiling for Production, and not for Development.
when I use this
mp = MediaPlayer.create(mContext, R.raw.ring);
It works 100% with my compiled Development APK and the sound plays... but after I compile it for Production and run it, i get the error "android.content.res.Resources$NotFoundException: File res/raw/ring.mp3 from drawable resource ID #0x7f050000"
Any ideas?
