问题
I try to create AVD. But Create button is deactive

回答1:
go to your SDK Manager and make sure everything required for API lv 17 is downloaded and installed
回答2:
You need to download a system image for the SDK you are trying to target. You don't have everything you need, which is why you can't create the AVD.
回答3:
Under CPU/ABI
it says "No system images installed for this target." Download the system images using the SDK Manager.
