android - YouTube api : Not connected. 调用 connect() 并等待调用 onConnected()

Question

我在 Android 应用程序中使用 YouTubeFragment 并在 Android 4+ 设备上发生以下崩溃。

java.lang.IllegalStateException: Not connected. Call connect() and wait for onConnected() to be called.

fragment 是这样开始的:

 XYouTubeFragment yFragment = XYouTubeFragment.newInstance(ytVideoId);
 activity.commitFragment(yFragment);

定义如下:

public class XYouTubeFragment extends YouTubePlayerSupportFragment {

    public static XYouTubeFragment newInstance(String url) {
        XYouTubeFragment youTubeFrag = new XYouTubeFragment();
        Bundle bundle = new Bundle();
        bundle.putString("url", url);
        youTubeFrag.setArguments(bundle);
        youTubeFrag.init();
        return youTubeFrag;
    }

    private void init() {

        initialize(Constants.YOUTUBE_API_KEY, new OnInitializedListener() {

            @Override
            public void onInitializationFailure(Provider arg0, YouTubeInitializationResult arg1) { }

            @Override
            public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player, boolean wasRestored) {
                player.setPlayerStyle(YouTubePlayer.PlayerStyle.DEFAULT);
                if (!wasRestored) {
                    player.loadVideo(getArguments().getString("url"), 0);
                }
            }
        });
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);

        MainActivity activity = (MainActivity) getActivity();
        activity.getSupportActionBar().hide();
        activity.findViewById(R.id.alert_list).setVisibility(View.GONE);
    }
}

知道哪里出了问题吗？
