将我的应用程序从 Eclipse 移动到 Studio 0.2.1 后，屏幕旋转会导致应用程序出现故障。
我希望我的应用在 Nexus7（和更大）、三星 Galaxy S4 和更小的设备（如果可能）上支持横向和纵向。
AndroidManifest.xml 文件是相同的。
该应用程序从陆地>港口和港口>陆地同样失败。
旋转屏幕时，会调用以下方法：
- onSaveInstanceState;
- 停止；
- 销毁。
该应用程序还包含 onSaveInstanceState 和 onRestoreInstanceState，但我不知道需要在这些方法中放置什么代码。
OnDestroy 包含代码：“android.os.Process.killProcess(android.os.Process.myPid())”。
如果可能，我想删除 ...killProcess... 代码并让我的应用根据 Android 生命周期指南执行。
但是，如果我删除 ...killProcess... 代码，当手动旋转屏幕时，操作栏会充满尽可能多的菜单项（在 Eclipse 和 Studio 0.2.1 上）。在诉诸 ...killProcess... 代码之前，我尝试了许多清单更改和代码更改的组合。
Android 4.3 版在 2013 年 7 月 26 日晚上加载到我的 Nexus7 上。我在 2013 年 7 月 27 日早上的测试产生了相同的结果。
我希望我不必移植回 Eclipse，因为 Android Studio 是这个星球上最好的开发环境。
提前致谢。
