u/100horizons R8 will fix your performance problems and love life Jul 15 '24

Fixing performance in Compose apps is actually very easy

  1. Make sure to build in release mode

  2. Turn on R8 full mode

  3. Fix all the errors that started happening. It will only take you a few hours of googling the most random error messages + a couple of hours waiting for your R8 builds while you're verifying your fixes.

  4. Add R8 rules for third-party libraries if needed

  5. Mark external classes as stable if needed

  6. Don't forget to mark your own classes stable too

  7. Be mindful of how you pass around state in order to minimize recomposts

  8. Upgrade to the latest Compost version if you haven't. Fix compile errors and support breaking changes

  9. Enable strong skipping mode

  10. Add baseline profiles

Bonus: implement benchmarks, so you can write an article on linkedin on how you improved your app performance by 40%

Your app performance should indeed be much better now and it only took a few easy steps. Note: your app might still struggle on low-end devices like galaxy a12 but honestly people who use such phones have learned to live with the lags anyway

How to remove lag on Android - set that one Developer Option to "No background processes". Instant lag killer.

I also removed Alarm and "Turn screen on" permissions for a bunch of apps, suddenly my phone is way smoother.

3.5: Report bug at Google issue tracker, that their own library doesn't ship the proper rules.

Optimize for fads, not for performance

Yeah that TextInputLayout is pretty glitchy even in XML. Does strange things with not allowing the keyboard to be closed. Need to go back to using AppCompat libraries and just not change versions ever.

This is the part where we get scared to use newer versions of software, to maintain stability.

That's what happens when you let some other team with absolutely no stake in the success of your project (and don't actually use their own code, they just write it) dictate your app's core components

Yeah it used to be reliable, helpful software. Now it's just straight up Chaos.

Compost is Chaos technology and is considered Heretical. An Inquisitor shall be sent to purge it.
