No Android Devices Connected

I am getting a "No Android Devices Connected" when trying Build and Run with the build settings set to Android.

I know the device is connected because I am able to compile and run Android apps from Android Studio. It is not the common problem that I haven't enabled USB debugging.

It almost seems like there is something else that needs to be configured in Unity. Does anyone have any thoughts?

Note that I got this before connecting to the device from Android Studio. If I quit Android Studio, I still get the error.

 

FYI: I can just build the APK and then install it using adb. Just can't do "Build and Run".

I also tried restarting Unity just in case it was in some strange state. No joy.

 

did you find any solution I have the same problem

 

I did get it solved, but I don't remember exactly what did it. I think it might have been that I didn't the correct Run Device in the Build Settings.
