Answer 1

当正在运行的程序的堆栈深度超过某个平台或VM特定限制时，抛出

java.lang.StackOverflowError。通常情况下，这只会在程序变为无限递归时发生，但也可能在正确编写（但深度递归）的程序中发生。

更改onPreExecute()方法：

progressDialog = ProgressDialog.show(getTabGroup(), "", getString(R.string.update));

到

progressDialog = ProgressDialog.show(MySpaceTabbedPanelActivity.this, "", getString(R.string.update));

在您的代码中，您在asyncTask方法中调用了onResume()，因此可能会出现递归发生和VM抛出错误。进行一次asynctask调用并从onResume()方法中分离asynctask。

某些设备上的TabHost应用程序崩溃仅适用于Android 4.0.3-4.0.4
