Google-signin: Native module RNGoogleSignin tried to override RNGoogleSigninModule error

[bimix]

I am trying to build authentication with Google in my React-Native app. Whenever I run the app it displays this error saying that there is a duplicate but in fact, there is no duplicate.

Steps to Reproduce

• Create a new RN project
• Download react-native-google-signin library
• Follow the steps to configure it in Android app.
• Run app.

Expected Behavior

It should run normally without errors and displays Google Login.

Actual Behavior

Environment

hello, thanks for reporting. remove packages.add(new RNGoogleSigninPackage());, that will work.

Does authentication work without it?

hello, thanks for reporting. remove packages.add(new RNGoogleSigninPackage());, that will work.

check the official repo, it clearly states that we must insert that line in there. Please read through first before hurrying into conclusions.

Is removing packages.add(new RNGoogleSigninPackage()); solved the problem ?

I am sorry, why would I do that? I need that package obviously!

@bimix as the error message suggests, the module is very likely being created twice.

If packages.add(new RNGoogleSigninPackage()); is present only once in MainApplication.java, it is probably added one more time through autolinking. And so you don't need the original call.

if its there through auto-linking, where is it then?
