我有这个应用程序使用 ViewPager 和 ViewPagerIndicator，由于某种原因，我不断收到以下错误。我似乎无法弄清楚为什么会出现错误。任何帮助将不胜感激。根据堆栈跟踪，我认为我的 main.xml 在 vi​​ewpager 启动的那一行存在问题，但我之前没有做过任何事情。这可能来自图书馆方面吗？

private ViewPager awesomePager;
private static int NUM_AWESOME_VIEWS = 3;
private Context context;
private AwesomePagerAdapter awesomeAdapter;
LayoutInflater inflater;
ProgressBar progressBar;

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    com.actionbarsherlock.app.ActionBar actionBar = this

使用 Fragment 时应使用 SherlockFragmentActivity

这个问题是由最新的更新引起的Android Support Library rev.13，我更新了我的库项目和自己的项目的支持包，从那时起问题就发生了。因此，当使用支持包 12 及以下版本时，该问题已得到解决。
