嗨，我在这里和谷歌上到处搜索，没有得到正确的答案。所以我发布了一个新问题：
我有几个与 1.6 到 2.3 完美配合的 Android 应用程序......
但是现在，使用 Android 4.0 (ICS)，我有用户报告说，当应用程序启动时，主页上的屏幕正在闪烁，除了“主页”和强制停止应用程序之外什么都做不了......（然后。你可以开始再次应用该应用程序，它最终可以工作...：O）
我已经在模拟器和包括带有 Android 4.0.4 的 Galaxy S 3 在内的多个设备上测试了该应用程序，但我永远无法重现该问题！:(( 看来问题主要出在 HTC One 上...
这是活动的简单代码
