I have a weird behavior on my xubuntu machine and I don\'t know why.
You see, the main case is Android Emulator Window don't have the proper focus even when you click on it. Yes, you can do any touch-operations, but frame still appears non-focused.
I've found a workaround for that:
Now, whenever you hang your cursor above the emulator window it'll gain correct focusing state and you'd be able to use you keyboard just fine.
