Thanks for filling a bug.

default-font-family works for me on android. (I did not tried with that specific font, but I confirmed that it worked with the Plaster from the slide_puzzle demo) I can't think of any reason why it wouldn't work. Do you have more details on why it is not working? Is there any log that could be helpful to debug the issue?

I try the Plaster font and it work fine. So I think the promble is from the font name. I use the fc-scan tool to extract the font information and find that I set the postscriptname for the slint-ui font-family . This wrong setting work fine on linux, but no for android. After I set the correct font-family, the problem has been solved.

Do I understand correctly that when using the correct font name it works for you now on Linux as well as Android?
