I am trying to create the android emulator for Nexus 10 using latest ADT(21) and SDK tools. I have the following configuration for the Nexus 10 AVD:
Screen S
I had the same issue. You can do one thing,
1) When you create AVD, make sure Use Host GPU option is checked.
It worked for me, in my Mac OS X Mountain Lion 10.8.2, and eclipse juno.
EDIT : Sorry folks for the confusion. There is no Google Nexus 10 skin (at the time of writing this). What you see in the image is a Nexus 10 equalant I created using Device Definition (AVD manager 2nd tab) feature of eclipse. It is just I named it as Nexus 10 and it is not default google emulator.
