Disable the Instant Run option in Android Studio. Instructions are in the Android Studio Instant Run documentation.

Instant Run tries to do hot swapping of your code; this causes the application class to be moved.

To disable Instant Run Go to File --> Settings--> Build,Execution,Deployment -->Instant Run ---> uncheck "Enable instant run"
