I downloaded and installed the latest Android Studio version which is 0.8.6 (beta) and I was stuck while trying to create a new Android Virtual Device.
I tried to follow these steps: https://developer.android.com/training/wearables/apps/creating.html but looks like the CPU/ABI is unavailable when I pick one of the types mentioned in that document (Android Wear Square/Round) and the skins named AndroidWearRound or AndroidWearSquare are also unavailble.
Here's a screenshot:

The above example works ... however even after downloading all required packages the button was deactivated. Later by fluke I realized it also gets deactivated when there is a space in AVD name. Though AVD manager never complain about it.

Also be sure to select only one choice in the Emulation Options. If both are selected OK will be disabled. (IMO: A radio button would have been a better option.)
