回答1:
I have the same problem on my Micromax AQ 5001 with Android 5.0. The solution under Android Studio 2.3.1 is Tools -> Android -> Enable ADB integration -> uncheck. You can return this check back if you need to debug your project after successful installation on device.
回答2:
switch off the "Verify Apps over USB" in the "Developer Options". If it does not work then try Revoke USB debugging authorizations in the Developer Options
..Answered too late , Hope this may help someone in the future

On the Asus Zenfone 2, simply disabling Instant Run fixed this for me.
Settings -> Build, Execution, Deployment -> Instant Run (uncheck the checkbox)
I was able to leave ADB integration enabled.
回答4:
Sometimes this problem can be caused if the folder in which your project is located has spaces in its project name. After I changed the project directory to a new folder with no spaces in the path name, everything started working fine.
My Android device was Micromax Canvas Doodle 4 running Lollipop (5.0). I was using Android Studio 3.1.
