Missing buttons in new Android Emulator

I converted my android project to android 3.0. But in the emul开发者_如何学Goator I miss al the buttons (menu, phone, camera e.t.c.). What am I doing wrong?

You can add the buttons using the Hardware Back/Home keys option in AVD Manager.

The tablet emulators don't have buttons.

Nobody answered this question. I am having a similar/possibly same problem.

I fired up the emulator in Android-Studio. I used the generic "galaxy nexus" image and tried to boot it up. It was very slow. And now the phone icon is missing, and so is the camera.

I can put the camera back but not the phone. Each time I boot it up again the same problem occurs.

I am running ICS 4.0 on the emulator.

I am running KDE/Kubuntu 13.04 on my computer.
