[Feature Request] Add support for the Google font provider

[ligol]

Google provide a Google font provider in Google play services 11+ in order for application to download font and share them between application. (https://developer.android.com/guide/topics/ui/look-and-feel/downloadable-fonts#the-basics)

The application on which I'm working on use that feature and one of my user who use MicroG instead of GooglePlayService receive a crash during font loading due to the font not available.

Would you be able to support that feature?

Is there any further consideration/update on this issue? I am interested into putting time/work into this issue if someone would kindly point me to some resources. I have opened downstream issue https://gitlab.com/CalyxOS/calyxos/-/issues/415 and am interested and potentially developing/finding a fix

@ligol Could you provide logcat/reproduce issue for me just so that we could compare?

@ligol I tried the downloadable fonts sample with MicroG: https://github.com/android/user-interface-samples/tree/main/DownloadableFontsKotlin

And it doesn't crash, but fails to download the font. Maybe your app isn't handling the error case properly?

I made the sample app work with https://github.com/grote/GmsCore/tree/1097-fonts-provider (still need to clean it up before making an PR).

Tomorrow, I will compile and install this on my Pixel 5 (Calyx OS) and see how it works with my issue

@grote Sorry for my lateness. I tested your code on CalyxOS AVD & had great results. Fonts sample (https://github.com/android/user-interface-samples/tree/main/DownloadableFontsKotlin) did not work at all without this FontsProvider, and I was able to reproduce Google Fi issue without FontsProvider.

With FontsProvider on top of CalyxOS MicroG, this resolved my issues with DownloadableFontsKotlin as well as with Google Fi crashing due to font resource not found. I can't WAIT until this is merged!

Great work! 👯 👍

Thanks for testing! Great that you could verify the fix.

I'm reopening this, cause the feature is not fully implemented - it doesn't actually provide fonts and various font weights, but just fallbacks to Roboto Regular. Probably can be improved, but works for not having apps crash, thanks to @grote :)
