I’m struggling to eject and build a project for 2 weeks now! after a lot of searching and reinstalling everything even windows, finally yesterday, I have managed to update my project from SDK 28 to 29 and build worked! But, now whenever I run the app on my real device unfortunately app has stopped error appears and whenever I build on a virtual device nothing happen only a white screen, so I created many new projects either with CRNA, exp or expo-cli command line and ejected them and same error unfortunately app has stopped appears again …
I don’t know why there are 2 ways to build a project one with the run.sh and the one documentation suggested. the one with run.sh try to run expo app even so it’s a native Android app it doesn’t require that!
I think expo documentation lacks a lot of integrity I don’t want to wait 2 more weeks to solve this
any help will be appreciated
Sorry you’ve been dealing with all of this. Just for clarification:
Are you saying that freshly created project with no code changes results in the unfortunately the app has stopped error after being ejected or detached?
Also, with your original project, have you tried looking in your device logs for any crashes that may be occurring? I see you mention Android once, is this occurring on iOS as well?

yes
I see you mention Android once, is this occurring on iOS as well?
i haven’t yet, is there a windows virtual device for IOS?
Also, with your original project, have you tried looking in your device logs for any crashes that may be occurring?
