最近我在我的 Android 应用中实现了 ActionBarSherlock。在 Google Apps 的开发者控制台的 Crash & ANR 报告中，有少量错误报告。我已经在模拟器 Android 2.2 到 4.2.2 中测试了该设备，在我的测试过程中出现了这样的错误，无论是在我的 Nexus 4 中还是在使用 Eclipse 运行的各种模拟器中。由于开发者控制台中没有给出用户消息，我无法识别导致此类错误的设备和 Android 版本。

下面是我的 onCreateOptionsMenu。menu 和 inflater 参数均来自 com.actionbarsherlock.view

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {

    SubMenu subMenu1 = menu.addSubMenu("More");
    subMenu1.add(Menu.NONE, 1, 0, "Feedback").setIntent(new Intent(getActivity(), ContactActivity.class));
    subMenu1.add(Menu.NONE, 1, 0, "Backup & Restore").setIntent(new Intent(getActivity(), SyncActivity.class));
    subMenu1.add(Menu.NONE, 1, 0, "Settings").setIntent(new Intent(getActivity(), SettingsActivity.class));
    subMenu1.add(Menu.NONE, 1, 0, "About").setIntent(new Intent(getActivity(), AboutActivity.class));

    MenuItem subMenu1Item = subMenu1.getItem();
    subMenu1Item.setIcon(R.drawable.ic_menu_moreoverflow);
    subMenu1Item.setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);

我在 onCreateView 方法中的 View Inflater 之后有 setHasOptionsMenu：

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.main_menu, container, false);

        this.setHasOptionsMenu(true);

现在我需要更多关于上述错误的可能原因的信息，或者至少我如何重现上述错误以进行调试。谢谢。
