Thank you for your contribution! Great to see someone working on new arch support for Android. Would be great if some more experienced Android developers can help test / review this @mikehardy @DoctorJohn @birdofpreyru @wjaykim

No way it has already been two months. I keep telling myself "I'll review this next weekend" 🫠

This does still need a look, but please please 🙏 interested folks, do not post +1s or "please review" etc.

When you do that, you are requesting unpaid labor and being insistent about it. Please be self-aware and recognize that's rude.

Review it yourself, do the QA yourself and post the results. Otherwise please be patient while others perform unpaid labor for you, yes?

[mikehardy]

Or alternatively, sponsor the effort ;-). Always a positive way to go!

Looks like this branch needs to be rebased.

Are there local dev instructions on how to run this locally? I've tried local publishing with yalc but the package doesn't seem to build with my existing apps that use Expo. Thanks!

edit: I just spent a couple hours trying set up my dev env and getting the Android + iOS example apps to build without any luck. I'm not sure this project is ready for a quick QA session by an outsider. It feels like Google/Admob should really be sponsoring this project.
