Android crashes on Login

[gesf]

Hello everyone,

I have successfully implemented this library on Android, however after fixing my previous issue (explained here and here) my Android app crashes, with the following error:

Any idea on how to solve this and what does it mean exactly ?

I see the line Caused by: java.lang.IncompatibleClassChangeError: com.google.android.gms.internal.zzbz$zza and I can make some sense of it, but honestly I don't know how to fix it.

This happens onPress of:

import GoogleSignIn from 'react-native-google-sign-in';
import { AUTH_ANDROID_CLIENT_ID } from 'react-native-dotenv';
...
async handleGoogleAuth() {
    await GoogleSignIn.configure({
      webClientId: AUTH_ANDROID_CLIENT_ID,
      offlineAccess: false
    });
    const user = await GoogleSignIn.signInPromise();
    console.log(user);
}

In addition I also get this often (but not related): (node:57155) MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 change listeners added. Use emitter.setMaxListeners() to increase limit

I am using the latest Google Sign-In OAuth SDK: 4.1.2.
Android: 6.0.1 / OxygenOS: 3.1.4
react-native-cli: 2.0.1
react-native: 0.53.0
node: 8.9.3
npm: 5.6.0

Thanks in advance!
