Android Question Black space on the sides of the activity

[astronald]

I'm testing on an Resizable emulator and when I open the app it appears with black space on the sides of the activity,
other apps in the emulator open fullscreen normally.
I tried putting the app in full screen and immersive mode but the same thing keeps happening.
Has anyone had the same problem? Is there any way to fix it?
I'm working with API 34 and B4A 13

i change

#SupportedOrientations: unspecified

then work's well,
but I have doubts if this affects my B4XPages project.

Activities in B4A are not expected to be resizable.
