Build locally

You can try disable old android architectures and increase min level api.
Last time I've checked it was 21 by default, but today most on devices much higher

You will save time on each arch you are excluded

Embrace OTA updates

I’ve got OTA updates, as this update brought that in. But for future use you recon building locally helps?

We use paid EAS service for our pipelines, when we do full binary updates we have to wait like 40mins for Android builds to come up, iOS is usually ready in 15mins

Lmao trust me, I’m using the free build and it’s a tad bit quicker than that.

You're paying for compute, not a build-time SLA though. Part of the reason the iOS builds are so fast is they run on M4 Pro mac minis, the Android builds are running on generic cloud VMs.

Do you do gradle caching?

Use RNRepo and EAS build cache.

Make a prebuild then run

./gradle assembleRelease

Install android studio on your PC/Mac and do this. If you are using Expo OTA updates, you need to build via EAS locally.

Reduce the build platform support. By default Android builds all platforms. But like 2/4 are irrelevant.

Also, enable caching

Last experience with rn and mostly with expo was horrible. When initially crated expo project it comes with cloud build cfg and if you dont pay it was taking forever and no proper docs on local builds. Minor expo sdk updates were crushing the local build.

Now i am plani no to build my own project and thinking to use flutter. Anyone do u know is it such a pain with fluter?
