Reproduction steps
I am using Exoplayer DynamicConcatenatingMediaSource for prefetching next song in song queue.
I am keeping only two sources at a time in DynamicConcatenatingMediaSource.As soon as I get the third source for adding in DynamicConcatenatingMediaSource, I remove the previous index source from DynamicConcatenatingMediaSource.

Following is the code snippet I'm using -:
public void onPositionDiscontinuity(int reason) { int newIndex = exoPlayer.getCurrentWindowIndex(); if (newIndex != currentIndex) { // The index has changed; update the UI to show info for source at // newIndex currentIndex = newIndex; removeMediaSource(exoPlayer.getPreviousWindowIndex()); currentIndex = exoPlayer.getCurrentWindowIndex(); } }
`
private void removeMediaSource(int index) {
if (index >= 0 && index < dynamicConcatenatingMediaSource.getSize()) {
dynamicConcatenatingMediaSource.removeMediaSource(index, new Runnable() {
@Override
public void run() {
if (exoPlayer == null) {
return;
}
currentIndex = exoPlayer.getCurrentWindowIndex();
}
});
}
}`
