出于某种原因，我的应用程序在super.onCreate. 它是一个扩展 fragmentActivity 的活动。

public class LiveMatchActivity extends FragmentActivity

那是我的 onStart()：

@Override
protected void onStart() {
    super.onStart();
    Analytics.getIntance().trackStart(this);
}

当我进入super.onStart()应用程序时。

那是日志：

    }
    eventsList.add(gameStartedEvent);
    liveMatchDetailsToSort.setEventsList(eventsList);
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.events_fragments, container,
            false);
    TypefaceManager.getInstance(getActivity())
            .assignTypeface(getActivity());
    events = ((LiveMatchActivity) getActivity()).getEvents();

    filterAndSortEventsList(events);
    ListView eventsListView = (ListView) view
            .findViewById(R.id.live_match_list);
    eventsListView.setAdapter(new LiveEventsAdapter());

    return view;
}

会是什么呢？

它不会在 super.onStart() 上崩溃，这里有问题

在 com.ftbpro.app.EventsFragment.filterAndSortEventsList(EventsFragment.java:211)

如果您可以粘贴 EventsFragment.java 文件的代码，我们可以尝试以更好的方式帮助您。
