不幸的是，系统 UI 已停止

Unfortunately System UI has stopped(不幸的是，系统 UI 已停止)

问题描述

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?

I gets this message every time I start 4.0.3 emulator in WXGA800 mode. My app works fine without running System UI except action bar does not appears and I can't test my actionbar functionality. My OS is Win7 x64. Sdk revision 19. Any ideas?

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！

I figured it out. It happens when hw.mainKeys set to false in AVD setings. Thanks for your answers!

推荐答案

不能同时拥有系统栏和导航栏:

You can't have both system bar and navigation bar:

原因:java.lang.RuntimeException:平板设备无法显示导航栏和系统栏

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

这取自 TabletStatusBar#makeStatusBarView 注意注释:

This is taken from the source of TabletStatusBar#makeStatusBarView note the comment:

     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) {
     }
