Could not find a connected Android device.org.openqa.selenium.WebDriverException:

[dduphorn]

Appium 1.6.3
Xcode 8.0
OSX: Sierra 10.12.2

Could not find a connected Android device.org.openqa.selenium.WebDriverException: An unknown server-side error occurred while processing the command. Original error: Could not find a connected Android device. (WARNING: The server did not provide any stacktrace information) Command duration or timeout: 21.52 seconds Build info: version: ‘2.52.0’, revision: ‘4c2593c’, time: ‘2016-02-11 19:03:33’ System info: host: ‘Darins-MacBook-Pro.local’, ip: ’ java.version: ‘1.7.0_79’ Driver info: io.appium.java_client.android.AndroidDriver

I occasionally get the above error and after I get it, I have to execute the below before it works again or Reboot.

ps -ef | grep “CoreSimulator” | grep -v grep | awk ‘{print $2}’|xargs kill -9

Any idea why?
