The title and picture say it all--my round android wear emulator shows the rect layout. I'd appreciate any tips that help me get the round emulator to show the correct interface.
Created AVD using instructions from: Android Documentation
Android Studio 0.8.1 Beta, SDK Tools 23.0.2, Wear target is 4.4W(API 20)
Creating the AVD using Wayne's Command Line method created an AVD that shows the correct UI
Make sure when you create you AVD that you select the following options for a round emulator:
Device: Android Wear Round (320 x 320: hdpi) Target: Android 4.4W - API Level 20 CPU/ABI: Android Wear ARM (armeabi-v7a) Skin: AndroidWearRound
Alternatively, you can create round or square emulators with the command lines:
android create avd --force -n WatchRound --target "android-20" --device "Android Wear Round" --skin AndroidWearRound --abi android-wear/armeabi-v7a
android create avd --force -n WatchSquare --target "android-20" --device "Android Wear Square" --skin AndroidWearSquare --abi android-wear/armeabi-v7a
It is important that Device and Skin are both consistent, and you cannot mix round and square with the same emulator. If the problem still happens, post a screen shot of your configuration.
You don't have to use the command line to create the AVD. You should just make sure you turn off "USE HOST GPU" as this feature currently doesn't support the round watch face.
I'd second Wayne's suggestion to use the command line to create the AVDs. If you just disable "Use Host GPU" from the UI, you get the round skin, but the wearable layouts are all still made for square displays, so the content is cut off in the corners. Also, using
android create avd --force -n WatchRound --target "android-20" --device "Android Wear Round" --skin AndroidWearRound --abi android-wear/x86
to create an x86 based emulator runs quite a bit faster on PCs in my experience.
