Answer 1

Tools > Android > Enable ADB Integration

Disable then enable. All's good

Answer 2

Clearing the Intellij IDEA (Android Studio) .idea directory which contains configuration information worked for me:

Exit Android Studio Navigate to the project you are trying to debug Backup any files inside .idea that you modified (if your project checks any of these into VCS) Delete .idea directory Open the project in Android Studio

This worked for me two months Back

Also Check any other process running in your computer on same port and kill it
