Android Material and appcompat Manifest merger failed in react-native or ExpoKit

Question

I updated \'android.support:appcompat-v7\' to 28.0.0.

But it brought an error from the build.

Attribute application@appComponentFactory          


        

Answer 1

Upgrading 'react-native-device-info' to version 2.1.2 fixed the error for me. See github.com/facebook/react-native/issues/25294#issuecomment-503024749

In short: the library used "services-gcm:+" as a dependency, and the latest gcm version caused this problem.
