Cannot resolve symbol 'FirebaseAuth'

Question

Why am I getting this error? My repository and Google play services are up to date and I've used all the requires steps for using Firebase like copying firebase code in both build.gradle(Project and app). The intellisence doesn't even show FirebaseAuth but displays other members of Firebase.

Answer 1

implementation 'com.google.firebase:firebase-auth:16.0.1'

make sure your firebase all the dependency are same version

Answer 2

I have android studio 3.3.1 installed. Compile is replaced with implementation. So you have to write

implementation 'com.google.firebase:firebase-auth:16.1.0'

You should replace version according to the warning you get.

Answer 3

add the following to the build.gradle (app)

implementation 'com.google.firebase:firebase-auth:9.2.1'

Answer 4

on dependencies in app gradle

implementation 'com.google.firebase:firebase-core:16.0.1' implementation 'com.google.firebase:firebase-auth:16.0.1'

this is useful android 3.0 and onwards versions auth:16.0.1 and core:16.0.1Firebase will work

Answer 5

Same problem. Clean your project with "Build"->"Clean Project".

Answer 6

Add this two dependencies into your build.gradle as 'compile' is replaced by 'implementation'

dependencies {

implementation 'com.google.firebase:firebase-auth:16.0.4'
implementation "com.google.android.gms:play-services-gcm:16.0.0"

}

For latest android studio version 3.0 and new one's

@androidstudio @firebase
