Read username from GoogleSignInAccount ( Google Fit Android API) - google-fit

Question

I'm using the Google Fit Android API to retrieve fitness data and it all works like a charm. I want to also access the name of the currently logged in user , which should be accessible by GoogleSignInAccount .getDisplayName();
I already asked this question but unfortunately didn't get any replies, and I cant figure it out with the documentation.
Example code:
//Create a FitnessOptions instance, declaring the data types and access type (read and/or write) your app needs:
FitnessOptions fitnessOptions = FitnessOptions.builder()
.addDataType(DataType.TYPE_STEP_COUNT_DELTA, FitnessOptions.ACCESS_READ)
.addDataType(DataType.TYPE_SLEEP_SEGMENT, FitnessOptions.ACCESS_READ)
.addDataType(DataType.TYPE_HEART_RATE_BPM, FitnessOptions.ACCESS_READ)
.addDataType(DataType.AGGREGATE_HEART_RATE_SUMMARY, FitnessOptions.ACCESS_READ)
.build();
//Get an instance of the Account object to use with the API:
GoogleSignInAccount account = GoogleSignIn.getAccountForExtension(this, fitnessOptions);
GoogleSignInAccount acct = GoogleSignIn.getLastSignedInAccount(this);
if (acct != null) {
loggedInUser = account.getDisplayName();
}
The problem is acct.getDisplayname().getGrantedScopes works like a charm, and I see the granted scope. When I try to read .getDisplayName I always get NULL.

I decided to use another way of logging in...
I now use this to configure sign in options and access :
// 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()
.requestProfile()
.build();
mGoogleSignInClient = GoogleSignIn.getClient(this, gso);
Then we start the sign in intent:
Intent signInIntent = mGoogleSignInClient.getSignInIntent();
startActivityForResult(signInIntent, 000000);
And now we handle the result:
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
// Result returned from launching the Intent from GoogleSignInClient.getSignInIntent(...);
if (requestCode == 000000) {
// The Task returned from this call is always completed, no need to attach
// a listener.
Task<GoogleSignInAccount> task = GoogleSignIn.getSignedInAccountFromIntent(data);
handleSignInResult(task);
}
}
private void handleSignInResult(Task<GoogleSignInAccount> completedTask) {
try {
GoogleSignInAccount account = completedTask.getResult(ApiException.class);
// Signed in successfully, show authenticated UI.
updateUI(account);
} catch (ApiException e) {
// The ApiException status code indicates the detailed failure reason.
// Please refer to the GoogleSignInStatusCodes class reference for more information.
Log.w(TAG, "signInResult:failed code=" + e.getStatusCode());
updateUI(null);
}
}
Tips: Make sure to use ApiException.class from Google and not AWS
