Expo app - built apk crashed after splash screen

Expo Development Tools
1

I build an apk using expo build:android -t apk command and the built was successful. However, the apk installed on my device crashed on Splash Screen.

It works on development and staging mode though.
When I switched to production mode, the app crashed just like the one for apk and I got this error. I can’t find which file the error came from as it is not clearly stated.

TypeError: undefined is not an object (evaluating 'B.map')

I’m thinking this might be the cause of app crash in the apk version. Any help and explanation is very much appreciated.

it looks like you are calling map on a variable that is undefined. if you’re unable to trace down the cause, see fyi/manual-debugging.md at main · expo/fyi · GitHub for tips on a more brute force approach

Ok, the issue is solved by changing some data passing from the backend and I can run on production mode.

But my apk still crashes despite having that solved.
Here’s the error from logcat:

I’ve checked the environment variables there seem to be no issue. In fact, we have been using the same logic for our previous standalone releases. The format is exactly like so Environment Variables in Expo using Release Channels | by Peter Piekarczyk | Medium

Solutions that I’ve tried:

  • updated packages
  • removed splash screen as some suggest
  • commented out OTA feature
  • edited environment variable files

None of these solutions worked so far. Looking for new suggestions on how to fix this…

you could try adding sentry or bugsnag to your app to get the full symbolicated error trace

It is added in our app but there seems to be no error reported

6

maybe it’s not properly configured?
