profile.getEmail() retrieving two string - one email and another blank

I'm signing up users with google in my app and then I'm retrieving there photoUrl, email, and display name.

The problem is that the

profile.getEmail();
is returning/retrieving two strings. One is email and another is blank.

Here's how I'm signing up them:

public class SignupActivity extends AppCompatActivity {

private static final int RC_SIGN_IN = 1;
GoogleApiClient mGoogleApiClient;
FirebaseAuth mAuth;
TextView appName;
ProgressDialog signinProgressDialog;
CoordinatorLayout coordinatorLayout;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_signup);
// Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
// setSupportActionBar(toolbar);

signinProgressDialog = new ProgressDialog(SignupActivity.this);

coordinatorLayout = (CoordinatorLayout) findViewById(R.id.signupCoordinatorLayout);

// Configure Google Sign In
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestIdToken(getString(R.string.o_auth_client_id))
.requestEmail()
.requestProfile()
.requestId()
.build();

// Build a GoogleApiClient with access to the Google Sign-In API and the
// options specified by gso.
mGoogleApiClient = new GoogleApiClient.Builder(this)
.enableAutoManage(this /* FragmentActivity */, new GoogleApiClient.OnConnectionFailedListener() {
@Override
public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {

}
} /* OnConnectionFailedListener */)
.addApi(Auth.GOOGLE_SIGN_IN_API, gso)
.build();

mAuth = FirebaseAuth.getInstance();

findViewById(R.id.sign_in_button).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if (isNetworkAvailable()) {
signinProgressDialog.setMessage("Signing in...");
signinProgressDialog.show();
signIn();
} else {
Snackbar snackbar = Snackbar
.make(coordinatorLayout, "No internet connection!", Snackbar.LENGTH_LONG);
snackbar.show();
signinProgressDialog.dismiss();
}
}
});

}

private void signIn() {
Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
startActivityForResult(signInIntent, RC_SIGN_IN);
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);

// Result returned from launching the Intent from GoogleSignInApi.getSignInIntent(...);
if (requestCode == RC_SIGN_IN) {
GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
if (result.isSuccess()) {
// Google Sign In was successful, authenticate with Firebase
GoogleSignInAccount account = result.getSignInAccount();
firebaseAuthWithGoogle(account);
} else {
// Google Sign In failed, update UI appropriately
// ...
}
}
}

private void firebaseAuthWithGoogle(GoogleSignInAccount acct) {
Log.d("firebaseAuthWithGoogle", "firebaseAuthWithGoogle:" + acct.getId());

AuthCredential credential = GoogleAuthProvider.getCredential(acct.getIdToken(), null);
mAuth.signInWithCredential(credential)
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
Log.d("signin_successful", "signInWithCredential:onComplete:" + task.isSuccessful());

Intent mainActivityIntent = new Intent(SignupActivity.this, MainActivity.class);
mainActivityIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
mainActivityIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(mainActivityIntent);
signinProgressDialog.dismiss();

// If sign in fails, display a message to the user. If sign in succeeds
// the auth state listener will be notified and logic to handle the
// signed in user can be handled in the listener.
if (!task.isSuccessful()) {
Log.w("signin_unsuccessful", "signInWithCredential", task.getException());
Toast.makeText(SignupActivity.this, "Authentication failed.",
Toast.LENGTH_SHORT).show();
}
// ...
}
});
}

@Override
public void onBackPressed() {
finish();
super.onBackPressed();
}

private boolean isNetworkAvailable() {
ConnectivityManager connectivityManager
= (ConnectivityManager) SignupActivity.this.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
return activeNetworkInfo != null && activeNetworkInfo.isConnected();
}
}


Here's how I'm retrieving the essentials:

public void retrieveUserInfo() {
FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
if (user != null) {
for (UserInfo profile : user.getProviderData()) {

// Id of the provider (ex: google.com)
providerId = profile.getProviderId();

// UID specific to the provider
uid = profile.getUid();

// Name, email address, and profile photo Url
name = profile.getDisplayName();
email = profile.getEmail();
photoUrl = profile.getPhotoUrl().toString();

}
}
}


Here, when I placed the email string in a
Toast
, I got 2 toasts, first one displayed the email and second one was blank.

I really don't know what's wrong here.

Please let me know.

Sorry if question seems to be badly formatted. I'm still a beginner here.

Answer

you are using for() loop maybe that's causing problem, once it gets the string and other time do not.
