我将 ActionBarSherlock 集成到我的 Android 应用程序中。它大部分运行良好，但有一个严重的例外......

当专门在 API 级别 10（对应于 Android 2.3.3）上运行时，并且仅在该版本上，当用户在两个特定活动之间导航时，会在某个时间点发生 StackOverflowError（如下所示）。调用堆栈显示此错误完全发生在 Android 框架内，与我的自定义代码无关。

我知道它与 ActionBarSherlock 相关的唯一原因是，如果我恢复对活动类的更改以便它们再次从标准 Activity 基类而不是 SherlockActivity 继承并恢复为非 Sherlock 主题，则不会发生错误.

Android 2.x 上的 UI 线程堆栈大小小于 Android 4.x。这意味着旧版本更容易出现 StackOverflowErrors。这解释了为什么您只在旧版本上体验到这一点。

ABS 的问题在于它会自动将一些嵌套视图添加到您的布局（包含操作栏的主布局）。您可以使用Hierarchy Viewer查看这些额外的视图。

如果您已经有一个包含许多嵌套视图的深度布局，那么添加 ABS 可能会添加额外的视图来填满您的堆栈。

我建议您简化布局并删除一些额外的视图。在 Android 开发者博客（Romain Guy）中有一些关于如何优化布局的技巧。如果您保存大约 2-3 个视图，它应该补偿 ABS 添加的内容，您应该没问题。

invalidateOptionsMenu()当被连续调用两次（在 onResume 中，然后在 onPrepareOptionsMenu 中）时，我刚刚遇到了类似的错误。

一旦我invalidateOptionsMenu()从 onPrepareOptionsMenu 中删除了调用，问题就消失了。也许这不是您的情况，但只是认为我会提供它作为可能的解决方案。
