Android ListFragment w / Fabric崩溃

Question

我刚刚开始搞乱Twitter的Fabric，无论我做什么，我似乎无法解决这个崩溃。我让它在一个活动中工作，但使用片段它不起作用，它适合教程。这是我的片段：

    public class ContentFragment extends ListFragment {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        TwitterAuthConfig authConfig = new TwitterAuthConfig("XXXXXX", "XXXXXX");
        Fabric.with(MainActivity.getInstance(), new TwitterCore(authConfig), new TweetUi(), new Twitter(authConfig));

        UserTimeline userTimeline = new UserTimeline.Builder().screenName("twitteruser").build();
        TweetTimelineListAdapter adapter = new TweetTimelineListAdapter.Builder(MainActivity.getInstance()).setTimeline(userTimeline).build();
        setListAdapter(adapter);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        return inflater.inflate(R.layout.fragment_content, container, false);
    }
  }

堆栈跟踪如下：
