Youtube Api Crashed, YouTubeService has leaked IntentReceiver

问题

I have built a native android app using YoutubeApi. Sometimes when I backpress from another activity to the activity with the youtubePlayer fragment (YouTubePlayerSupportFragment) it crashes with the following message:

05-19 15:43:10.869 4009-4009/? E/ActivityThread: Service com.google.android.youtube.api.service.YouTubeService has leaked IntentReceiver vsi@26900cf that was originally registered here. Are you missing a call to unregisterReceiver()?

I have heared I might need to add unregisterReciver(Broadcast Reciver), Although I haven't found a way to do it.

回答1:

Youtube api documantation seem to cover the soloution: https://developers.google.com/youtube/android/player/reference/com/google/android/youtube/player/YouTubePlayerFragment

"The YouTubePlayer associated with this fragment will be released whenever its onDestroyView() method is called. You will therefore have to re-call initialize(String, YouTubePlayer.OnInitializedListener) whenever the activity associated with this fragment is recreated, even if the fragment instance is retained across activity re-creation by setting setRetainInstance(boolean)."

Adding this line helped:

        frag.setRetainInstance(true);

frag is the youtube fragment I used for the api.
