您和本教程都没有提到您在 Android Wear Companion 应用中明确选择了 Pair with emulator.所以请尝试一下:

You, and the tutorial as well, haven't mentioned that you explicity selected Pair with emulator right inside the Android Wear Companion app. So please give this a try:

之后 ActionBar 应显示模拟器 - 正在连接...".再次执行 adb forward 命令，它应该工作.

Afterwards the ActionBar should say "Emulator - Connecting...". Execute the adb forward comand once again and it should work.
