Hello everyone.
I was wonderig if Anyone has managed to change the android NavigationBarColor?
I really need to have this future in My app.

its possible

May I know how?


designer part:
project link:

another solution image
for android only found in the screen properties
i guess thats what you think?

No that’s not what in meant.
I mean this.

I want the color to be blue.
But I don’t know how to do that.
It’s rendered by the AndroidOS.
Not My app.

Change the screen’s background color to blue.

I’ve already Done that.
But the NavigationBarColor in android can only be changed by code or trough it’s manifest file.

not possible

Thank you that answers My qeustion.
