I'm using ionic 3 for android app but got error in google plus login with firebase. Integrated ionic and cordova g+ plugins and my code is
gPlusLogin(){
this.nativeGLogin();
}
async nativeGLogin(){
try {
const gplusUser = await this.googlePlus.login({
'webClientId': '235*********ie.apps.googleusercontent.com',
'offline': true
})
return await this.afAuth.auth.signInWithCredential(firebase.auth.GithubAuthProvider.credential(gplusUser.idToken))
} catch (error) {
this.errorAlert(error)
}
}
