Xamarin android GoogleAccountCredential - xamarin

Question

I'm trying to use the Google Sign-In in Xamarin in order to create a YoutubeService instance. For now, i can get a GoogleSignInAccount with this function:
public void Login()
{
if(account != null)
{
CreateYoutube();
return;
}
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DefaultSignIn)
.RequestServerAuthCode("112086459272-o965mju8hjqqr1fq333g3am9hqrm650e.apps.googleusercontent.com")
.RequestEmail()
.RequestScopes(new Scope(YouTubeService.Scope.Youtube))
.Build();
googleClient = new GoogleApiClient.Builder(this)
.EnableAutoManage(this, this)
.AddApi(Auth.GOOGLE_SIGN_IN_API, gso)
.Build();
OptionalPendingResult silentLog = Auth.GoogleSignInApi.SilentSignIn(googleClient);
if (silentLog.IsDone)
{
Console.WriteLine("&Casting silentlog to google account");
GoogleSignInResult result = (GoogleSignInResult)silentLog.Get();
if (result.IsSuccess)
{
account = result.SignInAccount;
CreateYoutube();
}
}
StartActivityForResult(Auth.GoogleSignInApi.GetSignInIntent(googleClient), 1598);
}
protected override void OnActivityResult(int requestCode, [GeneratedEnum] Result resultCode, Intent data)
{
base.OnActivityResult(requestCode, resultCode, data);
if(requestCode == 1598)
{
GoogleSignInResult result = Auth.GoogleSignInApi.GetSignInResultFromIntent(data);
if (result.IsSuccess)
{
account = result.SignInAccount;
CreateYoutube();
}
}
}
It's working fine and i can get user's profile but the only way i've found to create a REST Api instance (like the youtube one) is by using the GoogleAccountCredential class (from the doc here: https://developers.google.com/android/guides/http-auth). Here is the code i want to use:
void CreateYoutube()
{
GoogleAccountCredential credential = GoogleAccountCredential.UsingOAuth2(
this /*Context*/,
YouTubeService.Scope.Youtube);
credential.SelectedAccount = account;
YouTubeService service = new YouTubeService(new BaseClientService.Initializer()
{
HttpClientInitializer = credential
});
}
but i can't find the api who contain GoogleAccountCredential in Xamarin. Is there another way to create a YoutubeService using oauth or an api who cover the GoogleAccountCredential class ?
Do not hesitate to ask me if you don't understand something in my question.

can't find the api who contain GoogleAccountCredential in Xamarin
You are looking the Nuget package: Xamarin.GooglePlayServices.Auth
Example Signin:
~~~
// mGoogleApiClient is a fully configured GoogleApiClient with the scopes your app need
var signInIntent = Auth.GoogleSignInApi.GetSignInIntent(mGoogleApiClient);
StartActivityForResult(signInIntent, 1010);
~~~
Now in your OnActivityResult you can retrieve the GoogleSignInAccount from the received intent:
Example OnActivityResult and the GoogleSignInAccount:
protected override void OnActivityResult(int requestCode, Result resultCode, Intent data)
{
base.OnActivityResult(requestCode, resultCode, data);
if (requestCode == 1010)
{
var result = Auth.GoogleSignInApi.GetSignInResultFromIntent(data);
GoogleSignInAccount account = result.SignInAccount;
/// Do something with your "GoogleSignInAccount"
}
}
