Trying to install app on real device following instructions:- http://developer.android.com/tools/device.html. At end Android Studio giving error:

Session \'a         


        

Answer 1

I tried invalidating cache, deleting build folder and gradle sync. Also, I couldn't uninstall because the app is not visible on device. So I tried uninstalling through ADB and it worked.

adb uninstall
