kivy - Kivymd App on Android has different colour icons to my Mac

Question

I compiled the KivyMD app I've been coding onto my phone and I had to specify in the buildozer.spec requirements to use sdl2_ttf==2.0.15 for the MD icons to actually appear. However, all the icons are fully white even though they have a text colour set to 0, 0, 0, 1:

MDFloatingActionButton:
    icon: 'plus-circle-outline'
    elevation_normal: 10
    user_font_size: '20sp'
    text_color: 0, 0, 0, 1
    md_bg_color: 1, 1, 1, 1
    pos_hint: {'center_x': 0.8, 'y': 0.03}
    on_release: app.CreateNewWorkout_1_Dialog()

On my Mac:

On my phone:

It also changes some of the text on buttons and in MDTextFields. I thought it had something to do with the sdl2_ttf==2.0.15 and tried other versions but the icons would only appear on this version. Any help would be much appreciated!

Answer 1

Because when compiling, you are using the KivyMD library from the PyPi and not from the master branch.

This is a bug in the library. Do not use the value 0, 0, 0, 1. If you need a black icon color, you can set the value to 0, 0, 0, 0.9:

MDFloatingActionButton:
    text_color: 0, 0, 0, .9
    md_bg_color: 1, 1, 1, 1
    pos_hint: {'center_x': 0.8, 'y': 0.5}
