仅在某些 Android 4.0.3-4.0.4 设备上，应用程序会在标签上崩溃。 IDE Eclipse。 日志如下。 如果设置高度最大 30dp，我可以防止崩溃。

最佳答案
当正在运行的程序的堆栈深度超过某些平台或VM特定限制时抛出
java.lang.StackOverflowError。通常，只有当程序无限递归时才会发生这种情况，但在正确编写(但深度递归)的程序中也可能发生这种情况。
onPreExecute()方法的更改:progressDialog = ProgressDialog.show(getTabGroup(), "", getString(R.string.update));
至
progressDialog = ProgressDialog.show(MySpaceTabbedPanelActivity.this, "", getString(R.string.update));
onResume()方法中调用了asyncTask，因此可能会发生递归并且VM抛出错误。
调用一次 asynctask，并将 asynctask 与 onResume() 方法分开。关于android - 仅适用于 Android 4.0.3-4.0.4 的某些设备上 TabHost 上的应用程序崩溃，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/30922122/
