不幸的是系统的用户界面已经停止 [英] Unfortunately System UI has stopped

问题描述

我每次启动4.0.3仿真器WXGA800方式得到这个消息。我的应用程序工作正常，但不运行的系统UI，除了操作栏不出现，我不能测试我的动作条功能。 我的操作系统是Win7的X64。 SDK版本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?

我想它了。它发生在hw.mainKeys设置为false，AVD setings。谢谢您的回答！

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

推荐答案

您不可兼得的系统栏和导航栏：

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

产生的原因：java.lang.RuntimeException的：平板设备无法显示   导航栏和系统吧。

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

     try {

         // bar on a tablet that has only the system bar
         if (mWindowManager.hasNavigationBar()) {
             throw new RuntimeException(
