android - 不幸的是，系统 UI 已停止

Question

每次我在 WXGA800 模式下启动 4.0.3 模拟器时都会收到此消息。我的应用程序在不运行系统 UI 的情况下工作正常，除了操作栏不出现并且我无法测试我的操作栏功能。 我的操作系统是 Win7 x64。 SDK 修订版 19。 有任何想法吗？

堆栈跟踪:

我想通了。当 hw.mainKeys 在 AVD 设置中设置为 false 时会发生这种情况。感谢您的回答!

你不能同时拥有系统栏和导航栏:

Caused by: java.lang.RuntimeException: Tablet device cannot show navigation bar and system bar

本文摘自TabletStatusBar#makeStatusBarView注意评论:

     try {
         // Sanity-check that someone hasn't set up the config wrong and asked for a navigation
         // bar on a tablet that has only the system bar
         if (mWindowManager.hasNavigationBar()) {
             throw new RuntimeException(
                     "Tablet device cannot show navigation bar and system bar");
         }
     } catch (RemoteException ex) {
     }
