The APK file does not exist on d

Sometimes we get this "The APK file does not exist on disk" when we run our app using Android Studio.

For me, that is because I change AS default build apk name as customized like "project_v1.1.1_2018-02-13.apk", but AS will still try to find the previous default name "app-debug.apk".

Solution: Refresh Gradle projects will fix this problem:)

Of cource if my approach doesn't fix your problem, maybe this link could help you more.
