My project works well with expo go: tne connection with its backend is fine.
I created the android apk, installed it with "eas build --platform android --profile preview" on my mobile and the android studio emulator.
When I launch the app, I have the loginscreen. But as soon as I valid my email/password, I have the pop up "Error.An error has occurred.Please try again". Both on my phone and the emulator.
I added an image to the loginscreen, located in the backend, and when I rebuild the apk and lauch the app again, the loginscreen appears without the image.
That leads me to say that the problem is linked to the no-connection between the apk version of the app and the back end. But why? I think I missed something obvious..but what? Thanks by advance for your help. Didier
