Stuck at debugging with message "Waiting for Debugger" in Android studio

Question

Whenever I try to use Android Studio's Debug function, the Run status would always stuck at:

Launching application: No local changes, not deploying APK

$ adb shell am start -D -n "com.example.nagamacmini.retrofitomdb/com.example.nagamacmini.retrofitomdb.activities.MainActivity" -a android.intent.action.MAIN -c android.intent.category.LAUNCHER
Waiting for application to come online: com.example.nagamacmini.retrofitomdb.test | com.example.nagamacmini.retrofitomdb

So the question is what can I do to make Android Studio debugging work?

Try to Restart/Reboot your Device. It's work for me.
