# (string) Presplash background color (for android toolchain)
# Supported formats are: #RRGGBB #AARRGGBB or one of the following names:
# red, blue, green, black, white, gray, cyan, magenta, yellow, lightgray,
# darkgray, grey, lightgrey, darkgrey, aqua, fuchsia, lime, maroon, navy,

android.presplash_color = #000000

This changes the background of the kivy loading screen to black, but the navigation bar stays white at the beginning.

I set the bar color to red in my main.py to demonstrate that the white background is set before any python code execution.

I found out that it's due to the LAUNCH activity using the Style "KivySupportCutout". I unpacked the apk, changed the style in styles.xml, repacked, and now it works as intended.

Is there no way to modify the Style KivySupportCutout through buildozer without unpacking the apk ?
