Email Verification not working

Your email verification does not work.Consider using AuthStateListener instead.

onCreate(...//
mAuthListener = new FirebaseAuth.AuthStateListener() {
before you verify email

R is in red in the entire code

At, the start I connected my app with firebase by adding codes in grandle and adding json file in projects-> app. Now, the problem is that whenever I make a new empty R goes on red before adding any activity everything is fone what is going wrong plz help. What i think is after attaching your app to firebase and adding json file and copying grandle codes we cannot add any new activity to do so u need to add all the activities before it am i right?
