'com.google.android.gms.common.api.GoogleApiClient' is deprecated

Question

I'm using in my app Google sign-in method and I have updated today my dependencies to:

implementation "com.google.firebase:firebase-core:17.1.0"
implementation "com.google.firebase:firebase-auth:19.0.0"

And I stared to get warnings about deprecated classes.

Warning:(26, 12) 'com.google.android.gms.common.api.GoogleApiClient' is deprecated

And

Warning:(27, 36) 'com.google.android.gms.common.api.GoogleApiClient.Builder' is deprecated

This is my code:

static GoogleApiClient provideGoogleApiClient(Application app) { //deprecated
    return new GoogleApiClient.Builder(app) //deprecated
            .addApi(Auth.GOOGLE_SIGN_IN_API).build();
}

My app is still working but how can I get rid of this warnings without the need to downgrade the versions?

Solution

Yeah GoogleApiClient has been deprecated.

As per the documentation:

When you want to make a call to one of the Google APIs provided in the Google Play services library (such as Google Sign-in and Drive), you need to create an instance of one the API client objects, which are subclasses of GoogleApi

Particularly for the authentication api, you now need to use GoogleSignInClient.

    // Configure sign-in to request the user's ID, email address, and basic
    // profile. ID and basic profile are included in DEFAULT_SIGN_IN.
    GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestEmail()
            .build();

    // Build a GoogleSignInClient with the options specified by gso.
    mGoogleSignInClient = GoogleSignIn.getClient(this, gso);

Thanks for your answer. So can I convert my code to be used with GoogleSignInClient?

Oh, it worked, thank you so much. One more small question please, when I used GoogleApiClient, in my MainActivity I was always googleApiClient.connect(); in the onStart() and googleApiClient.disconnect(); in the onStop(). Is this still required?

Welcome to SO! Your answer looks like to a complete application, whereas, if this is answering the originators question, you should put in some helpful comments.

The GoogleApiClient has many functions though that don't seem to exist for GoogleSignInClient though. How do you deal with those? Examples: blockingConnect, isConnected,clearDefaultAccountAndReconnect,disconnect . Also this function uses it: Auth.GoogleSignInApi.silentSignIn()
