BCVAX-Android VS iosched

Better yet, BC's app is comparable and is open source: https://github.com/bcgov/BCVAX-Android/

Doesn't need to go to a website; you can have "digitally signed" QR codes that aren't forgeable/crackable, like QC/BC/SK/ON are using and work offline. Because of the way it works, you can actually see BC's app's sourcecode.

You're welcome! Funny, you were analyzing the iOS app's source at the same time I was analyzing the Android app's source. On Android, it stores the JWK as an asset so it doesn't even hit the network to get the public key, meaning that it functions perfectly well in airplane mode. Thanks for the info about the JWT shananigans. I spoofed my card's alg as both "none" and "HS256" and it rejected both, as it should.

This project has a history, before the next major changes, I moved to a single activity, also I modularized the features before I followed one shared module, and two modules to support the mobile and the TV look here , for now, I'm targeting the mobile, after some customization for tablet, then I will try to target the TV, so maybe you will find some code from the previous solution like this module, which is no need for now as everything is modularized. thanks :)

I feel like everything I do is RecyclerView's (or now, Lazy Grids with Compose 😅) so definitely check out the more popular UI elements like that. Also poke around in Google's classic I/O app which will show standard practices they push on the industry.

google/iosched was worse :D

Google iosched app uses a good pattern for creating binders which maps between x.class to ViewBinder and ViewBinder to layout or ViewHolder as you can see here.

In the Google I/O, there is a comment in a lazy initialization of Shared Prefs:
