how to add a font to android application by kivy?

Question

i already add some txt files in android by this path /data/data/package-name/files/app/filefolder/file.txt

the txt file is in the same directory with main.py like /same_directory_with_main.py/filefolder/file.txt

based on this experience, i am trying to add some custom fonts in my application. and i makes directory exactly same way which add txt files.

part of main.py

from kivy.config import Config      
Config.set('kivy', 'default_font', [
    '/data/data/org.test.tubuc/files/app/font/NanumSquareR.ttfs',
    '/data/data/org.test.tubuc/files/app/font/NanumSquareL.ttfs',
])

but logcat says can't find the font path. here the log.

How can i add a font to android? thank you.

Answer 1

This is how I do it with the font file at the same level as main.py

#main.py
import os
tools_path = os.path.dirname(__file__)
icons_path = os.path.join(tools_path, 'NanumSquareL.ttfs')

And also on buildozer.spec include the extension ttfs

#buildozer.spec
source.include_exts = py,png,jpg,kv,atlas, ttfs, json

Hope it helps.
