Wow.. that IS weird. I'm not sure what the problem is here, but there are a couple of things I do differently:
1. Don't use MP3. Apparently the MP3 decoder on Android is a bit crufty. I was advised to use the OGG format and it works well. You can create OGG files using Audacity (it's free) http://audacity.sourceforge.net/ 2. I create MediaPlayer instances using a simpler method, specifically the following: A) ALL of my sound files are in resources/raw (not assets) B) When I want to load a sound for the game it has it's own MediaPlayer instance (same as you) C) I create MediaPlayer instances using the following: MediaPlayer.create(context, resourceId); where resourceId is something like: R.raw.bgmusic This does all the data source creation etc for me, and once the call is complete the sound is ready to play I wonder if the way you are creating the datasource is somehow creating a reference to the entire folder? Also, I don't think you need to create the stream (assuming you don't want to use the MediaPlayer.create() method I use). According to the doco the AssetFileDescriptor returned from openFd has a method called getFileDescriptor() On 23 Sep, 07:22, kk <kkostia...@gmail.com> wrote: > Hi all, > > I'm having some trouble streaming a looping background track for my > game using MediaPlayer. > > I have a bunch of short mp3s in /res/raw that I use as SFX and I play > using SoundPool. > The SFX playback all works fine...I'm mentioning it because it's > relevant as you'll see below. > > The background music track (also an mp3) lives in /assets.
