Hello, I am running into this error when I build for android, and I don’t know how what is causing it.

Same problems here. Last build 5 days ago was fine. Changed Google Maps Key in app.json and constantly failing now. based on sdk 43:

> Task :app:checkReleaseDuplicateClasses FAILED
> Task :expo:generateReleaseRFile

this is my problem as well … and I need the app to be build by now

I’m having the problem as well with Android builds, with bad gateway errors from bintray

Building with expo-cli failes every time now.

expo build:android -t apk

Building with eas-cli still seems to works though… (building now, will post an edit if it also fails)

eas build --platform android

EDIT: Yes, eas build works for both android and ios.(For us at least)

Build is running successfully again. Looks like the issue is fixed
