Google+ Sign-In for users without a Google+ profile - google-plus

Question

According to the official announcement, Google+ Sign-In now supports users without a Google+ profile.
However, when I visit one the official examples from an account without a Google+ profile, it only gives me the option of signing up for Google+.
What's the way to implement this feature? I've been checking the official docs as well but I can't find any references to this topic.

Let's make this snippet work shall we?
package com.example.googleplusauth;
import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.api.GoogleApiClient;
import com.google.android.gms.common.api.GoogleApiClient.ConnectionCallbacks;
import com.google.android.gms.common.api.GoogleApiClient.OnConnectionFailedListener;
import com.google.android.gms.plus.Plus;
import android.app.Activity;
import android.content.Intent;
import android.content.IntentSender.SendIntentException;
import android.os.Bundle;
public class MainActivity extends Activity implements ConnectionCallbacks,
OnConnectionFailedListener {
/* Request code used to invoke sign in user interactions. */
private static final int RC_SIGN_IN = 0;
/* Client used to interact with Google APIs. */
private GoogleApiClient mGoogleApiClient;
/*
* A flag indicating that a PendingIntent is in progress and prevents us
* from starting further intents.
*/
private boolean mIntentInProgress;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(Plus.API, null)
.addScope(Plus.SCOPE_PLUS_PROFILE)
.build();
}
#Override
protected void onActivityResult(int requestCode, int responseCode, Intent intent) {
if (requestCode == RC_SIGN_IN) {
mIntentInProgress = false;
if (!mGoogleApiClient.isConnecting()) {
mGoogleApiClient.connect();
}
}
}
#Override
protected void onStart() {
super.onStart();
mGoogleApiClient.connect();
}
#Override
protected void onStop() {
super.onStop();
if (mGoogleApiClient.isConnected()) {
mGoogleApiClient.disconnect();
}
}
#Override
public void onConnectionFailed(ConnectionResult result) {
if (!mIntentInProgress && result.hasResolution()) {
try {
mIntentInProgress = true;
startIntentSenderForResult(
//result.getIntentSender(),
result.getResolution().getIntentSender(),
RC_SIGN_IN, null, 0, 0, 0);
} catch (SendIntentException e) {
// The intent was canceled before it was sent. Return to the
// default
// state and attempt to connect to get an updated
// ConnectionResult.
mIntentInProgress = false;
mGoogleApiClient.connect();
}
}
}
#Override
public void onConnected(Bundle connectionHint) {
// We've resolved any connection errors. mGoogleApiClient can be used to
// access Google APIs on behalf of the user.
}
#Override
public void onConnectionSuspended(int cause) {
mGoogleApiClient.connect();
}
}
