我有一个非常奇怪的异常，当我的应用程序恢复时出现（在我切换到其他应用程序然后返回到我的应用程序之后），虽然它并不总是抛出，但只是不时抛出。

异常的部分非常简单。我使用 ViewPager (v4) 并有两个对话框类，第一个子 DialogHelp：

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    View view = super.onCreateView(inflater, container, savedInstanceState); [line 50]

第二个父 PMDialogFragment（扩展 DialogFragment）：

    @Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
app = (PMApplication) getActivity().getApplication();

    View view = inflater.inflate(layoutId, container); [line 50]

在logcat下面：

我真的不知道是什么原因造成的以及如何解决这个问题。如果总是重复，那就容易多了。

我在想也许它与喜欢制造问题的 WebView 组件有关。另一个可疑的事情是在我有时运行 AsyncTask 的主应用程序的 onResume 中。但是日志并没有暗示这一点。

你有什么建议会导致这种情况吗？提前致谢。（android min sdk 11，在 android 4.0.4 的设备上运行）。
