我有一个我一直在为Android开发的应用程序。应用程序从Eclipse安装并运行良好，但是当我导出.apk时，将其放在手机上并安装它然后应用程序将无法运行和关闭。
我在logcat中收到此消息：
05-01 14:57:21.167: E/WindowState(839): getStack: Window{1655a746 u0 com.example.testapp/com.example.testapp.MainActivity}
couldn't find taskId=551 Callers=com.android.server.wm.WindowState.computeFrameLw:1054
com.android.internal.policy.impl.PhoneWindowManager.layoutWindowLw:4904
com.android.server.wm.WindowManagerService.performLayoutLockedInner:10917
com.android.server.wm.WindowManagerService.performLayoutAndPlaceSurfacesLockedInner:11857
之前有其他人遇到过这个吗？任何想法？
更新
实际上是造成这个问题的原因：
