Error message on Android phone when starting app

Expo SDK
1

I’ve just updated to v34 from v32 following the upgrade guides. Now when trying to run my app with my android phone I get:

08-14 19:46:12.688  2520  2520 E ExperienceActivity: java.lang.NullPointerException: Attempt to invoke virtual method 'host.exp.exponent.j host.exp.exponent.j.b(java.lang.String, java.lang.Object[])' on a null object reference
08-14 19:46:12.691  1368  2091 E ActivityTrigger: activityResumeTrigger: not whiteListedhost.exp.exponent/host.exp.exponent.experience.ExperienceActivity/115
08-14 19:46:12.704  1368  2091 E ActivityTrigger: activityResumeTrigger: not whiteListedhost.exp.exponent/host.exp.exponent.experience.ExperienceActivity/115

I’m using expo cli tool, running with expo start -c. I tried already removing node_modules and reinstalling the whole app.

Any ideas?
Thanks a lot!

Hey @ramadis,

Just to clarify, is this a Managed or an ExpoKit project?

Cheers,

It’s a managed app. We looked into it and it was an outdated react version installed within our dependencies. So force-upgrading to the correct version did the trick. Thanks for your help!

Happy to hear you got it solved!
