Android的工作室：＆QUOT;确定]按钮＆QUOT禁用;创建新的AVD＆QUOT;窗口

我下载并安装了最新的Andr​​oid Sutdio版本，这是0.8.6（测试版），并试图创建一个新的Andr​​oid虚拟设备我被卡住了。结果
我试图按照下列步骤操作： https://developer.android.com/training/穿戴式设备/应用/ creating.html 但看起来像CPU / ABI不可用时，我挑那个文件（Android Wear方/圆）中提到的类型之一，皮肤命名AndroidWearRound或也AndroidWearSquare unavailble。
下面是截图：

I downloaded and installed the latest Android Sutdio 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:
