Cache Fonts take too much time

I am using an apple font called PingFang in my app , here is the code


in development mode and it was quite fast to cache the six fonts,it just take a few seconds to skip the splash screen and enter the app home page.
but after i installed the apk file to my phone,it is keeping staying in the splash screen a very long time i configed in the app.json. i thought it might because the .ttf files are too large
since each .ttf have a size of about 10MB. how to deal with this issue?

We’re working on some improvements that will bundle your assets with the initial install of standalone apps that would help. 10MB seems like a lot though, I suspect you will be able to shrink the ttfs quite a bit by dropping glyphs you aren’t actually using anywhere in the app.
