Loading screen for loading the game?

This question has been asked a few times before but somehow I was unable to find a clear answer.

So I have quite a large project that takes a couple of seconds of black screen to load when it is launched on device. So, for obvious reasons, it would be way better to have a loading-progress screen or at least a static loading screen during this time.

Is this possible? 

I’m using composer and we’re talking about Android.

You can load an image at the top of main.lua and then remove it when your app is loaded.
