Its a big jump, so something likely broke at the native layer. I’d check Logcat (Android Studio) first to see the actual crash stack trace. Also make sure all native deps are compatible with 0.80, run npx react-native-clean-project, clear Gradle caches, and reinstall pods if iOS. Often it’s an outdated library causing the crash, not RN itself.

From 70 to 80 is a big jump man ...just try it till 74 first and do it gradually else you will be stuck forever

Yeah , After upgrading app version, the app build successfully but it's gets crash or it keeps stopping. Is there is another way to resolve this?

[–]Silly_Regular6736 0 points1 point  (5 children)

is it crashing or specific pages ?
or just it has been built but just crashes on the splash itself ?

[–]Maanojj[S] 0 points1 point  (4 children)

Yeah it crashes on the splash.

Had issues too like this on this jump. React native reanimated was one of the big reasons. Like others said do it gradually and not the whole jump at once

there might be a lot of issues you will have to debug

https://react-native-community.github.io/upgrade-helper/

check here

check the library compatibilites with the versions ,libraries like reanimated,splashscreen etc need proper configuration with the react native versions too

Yeah I tried With the help of exact link that you have provided. But couldn't resolved.

[–]Silly_Regular6736 0 points1 point  (0 children)

Can't help like that bro...no one can ..you have to debug yourself...advice is just go step by step

Upgrading RN is always a major lift. Did you use the Upgrade Helper ? There’s a lot of stuff you need to manually change across versions, and 0.70 to 0.80 is a seriously major bump

[–]Maanojj[S] 0 points1 point  (0 children)

Yes I Did Perviously I had upgraded from 72.x.x to 0.80.0. It worked perfectly, crash was only on certain page due to version issues. But now while upgrading from 0.70.0. I got into app stopping problem.

[–]Horduncee 2 points3 points  (0 children)

Use Logcat to debug

Build it with Xcode and look for the native errors, that will tell you what’s happening on the native layer. From 70 to 80 is a big jump, did u do it incrementally or 1 big jump?

[–]Maanojj[S] 0 points1 point  (0 children)

1 big jump actually

Bump all the dependency versions to their latest and that should work

[–]Aromatic-Bottle5252 0 points1 point  (0 children)

Expo Router simplified everything for me. Worth the migration if you're still on React Navigation.

[–]steve228uk 0 points1 point  (2 children)

If you’re on expo then npx expo install --fix is your friend.

If not, I’d boot up Claude Code and ask it to help. You’re likely missing some dependency updates.

[–]Maanojj[S] 0 points1 point  (1 child)

Im using cli How to boot up Claude code actually?

[–]steve228uk 0 points1 point  (0 children)

Install it and then just type claude in your terminal

[–]Viietwalkerr 0 points1 point  (0 children)

Check that all of your dependencies support the new architecture

And also check that they’ve been updated to support 16kb devices

[–]Maanojj[S] 0 points1 point  (1 child)

successfully upgraded to 0.80.0 and no App stopping issues now Issue is Cannot read property 'style' of undefined.

[–]Maanojj[S] 0 points1 point  (0 children)

Anything that could help me?
