我在Android应用中使用YouTubeFragment，并在Android 4+设备上遭遇以下崩溃。
java.lang.IllegalStateException: Not connected. Call connect() and wait for onConnected() to be called.

片段正在这样开始：
XYouTubeFragment yFragment = XYouTubeFragment.newInstance(ytVideoId);
activity.commitFragment(yFragment);
并定义如下：
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);
}
}
知道可能出现什么问题吗？
答案 0 :(得分：-1)
