what can i do? should i unload tracks that i don't need anymore? how much memory is consumed per track? i expected audiotrack to be a small buffer, streaming the data from a file
2

You can set for every AudioTrack if it should use streaming or not.



Or you increase the Java heap size… I think the default is 128 MB.

3

i was using 700mb.

If you are using streaming, you have to release streamed audio player by implementing TrackStateListener.



@Override
public void trackStopped(AudioTrack track) {
   track.clearTrackStateListeners();
   track.release();
}
