Try installing a new launcher app (it really doesn't matter if you want it or not, you'll only need it for a few seconds) from the Play Store. Once it's installed, press the home button and Android should prompt you to choose a home app. Choose the one you want, select "Always", and then you can uninstall the launcher app you just installed.
You'll need to modify the Device Definitions. To do this, find the "Device Definitions" tab in the Android Virtual Device Manager and double click on the device you're using. Make sure the Buttons are set to Hardware. Don't forget to update your device settings: Source: Stackoverflow
