Description

I have problem with release build of react native. App successfully generated and install in device but crash while open the app.

With android studio LOGCAT I get the log of app and this is the error

018-10-31 23:46:36.803 23221-23239/? D/ReactNative: CatalystInstanceImpl.runJSBundle()

of course in debug build app work correctly with any problem

I searched a lot in previous issue and stackoverflow but any of them wasn't for release build.

@ingviso do this steps in terminal at project root directory
1.(in project directory) mkdir android/app/src/main/assets
2.react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res
this produce 2 files that fix the problem. if other files created delete them
for determines other files you can use git.
3.react-native run-android

this fix the problem for me

It looks like you are using an older version of React Native. Please update to the latest release, v0.57 and verify if the issue still exists.

The ":rewind:Old Version" label will be removed automatically once you edit your original post with the results of running react-native info on a project using the latest release.

Was this resolved by updating to latest react-native release ?
Running into same issue with react-native 0.55.2

Wow! Been pulling my hair out over this. Why does this work? I inherited a project that doesn't actually have an index.js file so I updated your script to use index.android.js but why does my debug project run with no problem but the signed apk release build crash on startup.

Thanks again!
