Hi! , I am not able to receive the access and refresh tokens with this library.
I wanted to exchange the ActiveToken to access and refresh token directly from my app by calling this endpoint
https://developers.google.com/identity/protocols/OAuth2WebServer#exchange-authorization-code but I only receive access_token with expires after 1 hour and without refresh_token. How can I access Google services like Gmail or Drive by using this library? Maybe I’m missing some authentication flow?
Thanks for help :/

Hello!

I created a package and inside it I used GoogleClientPlugin.
When I work with the package inside the Sample project where I develop the nugets everything works fine, but when I want to test the packege as a nuget in another project I get this error when I try to log in with google:
Exception is: Plugin.GoogleClient.Shared.GoogleClientBaseException: 10:
at Plugin.GoogleClient.GoogleClientManager.LoginAsync () [0x000cb] in <9a6ffdce03a64aceaeeebe3956587f25>:0
at [my function]

The solutions I found was to verify the package name or the fingerprint and both of them are ok.
If you can see, the exception doesn't help me because the message it's "10:" and I can't find anything about it on google or in issues.
If you know why I get this error message please help!

Thanks!

Hello

Apple is starting to refuse any application containing a reference to the class UIWebview. The Xamarin.Google.iOS.SignIn package had such a reference until the last update to version 5.0.2.1.

I tried to add it in my project but unfortunately it seems that your plugin is only compatible with the version 4.X of the Xamarin.Google.iOS.SignIn (either that or I'm dumb and didn't manage to make it work)

If you want your plugin to be usable on iOS you need to make it compatible with the version 5.0.2.1

Hello Goodnight.

I have already followed all the steps to be able to log in but I get the message "Google login could not complete your process correctly".

I tried everything and I can not get it to connect with the app, I saw all the cases that were presented and even then I can not make it connect, could you help me?

1- configure application in google for android

2- configure application in firebase
3 - enter the code that is with the example

4 - Download the Google repository

He keeps sending me the same message.

Downloaded the solution; just removed Ios and only included Android App; updated the manifest file, got new google service json file; do have sha1 as well; Build run fine; on login using gmail got below error.

HI, thanks for the amazing plugin, but i keep getting the same error on iOS while on android i fully functional.
The error i get is when i launch the app on iOS when calling the GoogleClientManager.Initialize(); it trows an error saying "Value cannot be null. Parameter name: path"

Desktop:

• OS: iMac High Sierra

Smartphone (please complete the following information):

• Device: iPhone6 Plus
• OS: 12

Currently OnLogin, OnLogout and OnError events are defined as follows:

        static EventHandler<...> _onLogin;
        public event EventHandler<...> OnLogin
        {
            add => _onLogin += value;
            remove => _onLogin -= value;
        }

I get you have a particular usage in mind when using this library.

In particular you whould like us to subscribe to OnLogin before requesting user data and you want us to unsubcribe as soon as we get the results; maybe using only an instance of GoogleClient throughout the entire app, by the way this could not be possible or may not be the programming style we are using.

In those different scenarios a static backfield causes problems. Ranging from the same handlers being called multiple times to memory leaks.

I'd suggest to remove the static keyword and turn to a simple event.

        private EventHandler<...> _onLogin;
        public event EventHandler<...> OnLogin
        {
            add => _onLogin += value;
            remove => _onLogin -= value;
        }

which leads to this

public event EventHandler<...> OnLogin;

Hi! I don't know if it is a bug, just my user reported that my app crashes. It looks like he is the only one who has faced with this. Could you please tell me where I'm wrong? Thanks in advance! :) That's all we know:

I need to access current login user data not triggering Login each time.

Describe the solution you'd like
Add property for current login user to IGoogleClientManager. If it is null user not login.
Android and iOS has native API for getting login user.

Describe the bug
I'm sorry. I'm pretty sure this isn't a bug, but I keep getting this error no matter what I try when debugging on the Android emulator from Visual Studio 2017.

1. Where does the google-services.json file go? Does it go in the Android project root, under Resources, or both?
2. Does the build action on the json file need to be set? I've tried setting it to None as well as GoogleServicesJson.

Note that I needed to change the package name so I deleted and recreated the Android App (NOT the Project) in Firebase and re-downloaded the latest google-services.json file.

To Reproduce
I run the emulator, click on Google Sign-In, select my account, and then I get this error.

Desktop (please complete the following information):

• OS: Windows 10 Visual Studio

Additional context
Add any other context about the problem here.

I am using latest version of plugin.googleClient 2.1.5 the problem is coming in Android

Describe the bug
I'm not able to locate in the docs a definition of what the expected behavior is. However, I've noticed that this library performs differently on iOS than it does on Android. When using CrossGoogleClient.Current.ActiveToken to retrieve the active token after a successful Google Login I've noticed that on iOS this property returns an OAuth Access token however on Android it returns a JWT.

The difference here being that an OAuth Access Token must still be exchanged with the Google
authorization server in order to obtain an authorized bearer token. While a JWT is a fully signed authorization that can be used as the bearer token on some Google APIs.

I am using a back end server that abides by the OAuth protocol and thus does not know or use JWTs. I would like to receive the OAuth Access Token under both iOS and Android implementations.

To Reproduce

user = new UserModel();

GoogleResponse<GoogleUser> googleUser = await _googleClientManager.LoginAsync();

user.Name = googleUser.Data.Name;
user.EmailId = googleUser.Data.Email;
user.Picture = googleUser.Data.Picture.ToString();
user.Provider = "google";
user.ProviderId = googleUser.Data.Id;
user.ProviderToken = CrossGoogleClient.Current.ActiveToken;

Supporting Documentation
Google API Docs for GoogleSignInAccount show that getIdToken() will return a JWT and getServerAuthCode() will return a "one-time server auth code to send to your web server which can be exchanged for access token".

The Google Sign In could not complete it's process correctly occur after click on login button (GoogleClientBaseException)

I need the OnLogin method to also return the token id.

Hi,
I'm just now to the point where I'm trying to run my app. on the iPhoneSimulator on VS 2017. My iMac is connected. The app loads, but then when I click on the button to login to Google, I'm getting:
Error: There was a problem reading or writing to the application keychain.
It's blowing up on the LoginAsync method:

public async void LoginAsync()
{
    _googleClientManager.OnLogin += OnLoginCompleted;
    try
    {
        await _googleClientManager.LoginAsync();   <-- Blows up here
    }

I'd appreciate any help you can provide. I'm still very new to mobile development so please bear with me. Thanks.

After success sign in on aAndroid, token is empty.
Log from plugin: Active Token:
On ios it is ok

im using xamarin forms, its works fine on debug mode but when i generate the apk file and install on device, it fails with the exception: The google sign in could not completed it's process correctly

Describe the bug
When I'm calling LoginAsync, it hides my app. Then the popup with google accounts is shown and after choosing one nothing happens. The app doesn't crash.

To Reproduce
Steps to reproduce the behavior:

1. Call LoginAsync();

Expected behavior
The popup doesn't hide application and the popup is shown on the same page where it was called.

Hello ,
I have followed all steps .
now my onActivityResult is getting called but if i see Data is not null but Data.data is null where i am expecting actual result.
also CrossGoogleClient.Current.OnLogin is also not getting called.
this issue is on android.
Please help what i am doing wrong.

I simply download and open the solution with Visual Studio 2019.
The solution does not compile.
Sdk dependencies cannot be loaded.

Maybe something changed in the layout of the project file.

Hello guys, how i promised, i started the UWP implementation... But since Google does not provide an SDK, it is necessary to use the browser to log in. With this, this architecture model, using Interface, greatly hinders the deployment and the use of the client by a developer. Because I can not expose to the dev specific methods of each platform, to solve this we can use the same architecture used in the Xamarin.Essentials project. I can help with the migration.

LoginAsync() is triggered, testing on Android..
A box pops open to select a User to continue with, after that nothing happens ..
OnLogin is never fired, no permissions are requested although the Scope is filled.
CrossGoogleClient.Current.OnLogin += CrossGoogleClient_OnLogin;
var googleUser = CrossGoogleClient.Current.LoginAsync();

Why doesn't anything happen after the account selection ?
Did I miss something ?? I followed the Setup as described.

Hi,
In iOS Getting error ->
The type or namespace name 'ISignInUIDelegate' could not be found (are you missing a using directive or an assembly reference?)
After Update xamarin.Google.iOS.Sign to 5.0.2.1

Plugin.GoogleClient 2.0 needs xamarin.Google.iOS.Sign >= 5.0.2.1

"Can't able to Submit ipa with "Plugin.GoogleClient 1.1.1 " getting error
ITMS-90809: Deprecated API Usage - New apps that use UIWebView are no longer accepted. Instead, use WKWebView for improved security and reliability. Learn more (https://developer.apple.com/documentation/uikit/uiwebview)."

Plugin.GoogleClient does not function properly after iOS social login permission alert. It works well on Android devices. on iOS, after clicking on Continue for social login permission, it flickers and does nothing.

Steps to reproduce:
Install app on iOS device (iPhone). Assuming instructions were followed for this nuget package. Build and deploy the iOS app. Launch the app and select Google login. You will be prompted by iOS for permission for social login. Select "Continue" and it flickers and hangs after couple login attempts.

The expected behavior is that it should follow that of Android device.
