How do I show a blank screen with a message on my app launch instead of splashscreen on tablets?

Question

I am planning to restrict my app to tablets but in the sense that I don't want to add compatibility screen etc. options in manifest. Currently, on app launch my manifest has a splashscreenactivity which launches for about 3 seconds then moves on to another fragment. I already have the code in my app that detects if the device is a tablet or not (say istablet()) , I was wondering if there is a way I can display black screen with a TextView on app launch for tablets letting the user know the app is not compatible on tablets rather than splash screen and follow up fragment.

Any ideas?

Can I call the layout in the application class somehow for the black screen and restrict it from routing further for tablets?

Any help would be greatly appreciated :)
