我在Exoplayer中使用Recyclerivew。我想释放Exoplayer Activity上的ViewHolder。我在Exoplayer中使用Exoplayer。我无法找到释放 public void releaseMemory() {
audioCapabilitiesReceiver.unregister();//Method in the ViewHolder
player.release();
}
public void releaseMemory() {
viewHolder.releaseMemory();//Method in the Adapter
}
@Override
protected void onDestroy() {
videoAdapter.releaseMemory();//Method in the Activity
super.onDestroy();
}
的任何方法。
RuntimeException现在我得到了E/AndroidRuntime: FATAL EXCEPTION: main

你可以停止玩家onStop（）方法来代替onOtroy（）;
