Unfortunately System UI has stopped [duplicate]

Question

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?

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

Answer 1

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

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

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) {      } 

Answer 2

put hw.mainKeys=yes in your .android->avd->youavdfoldername->config
open file and change hw.mainKeys=yes its work for me
