App name displayed when finish() Dialog Activity

Question

I want to secure my app with a fingerprint authentication dialog activity, it works, but if I choose to close the dialog here is what happens :

If I finish() the activity it flashes on the screen but it's still annoying. I am using android:theme="@style/Theme.AppCompat.Light.Dialog" theme.

Is there any way to prevent this from poping up ?

Answer 1

Actually I just figured out why. It's because I was using AppCompactActivity. Using a simple Activity fixed the problem.
