android studio Layout Inspector 无法使用

提示错误：Application not inspectable. Deploy an app or navigate to a debuggable app on your device to begin inspection.

遇到这种情况怎么处理？

Restart ADB:

• If you are using Android Debug Bridge (ADB), try restarting it:

  adb kill-server
  adb start-server
  

然后就发现Layout Inspector可以正常使用了！
