I've set up my android app with a drawer navigation menu and after all the set up my app is just showing a white blank screen without launching my LAUNCHER activity and without doing nothing.
I know is quite obsolete but i can't figure out what's going wrong, also because i don't have any log errors.. i think is a problme of theming, i'll post some code below.
Thanks for the help.
This is what the app is showing:
