Recent migration attempt

[Thaina]

Since there is deprecation and migration recommendation from signin system

: copied from readme >

https://developer.android.com/identity/sign-in/legacy-gsi-migration
https://developers.google.com/identity/sign-in/ios/quick-migration-guide

Thank for ios fix which was cherrypicked from this fork : https://github.com/pillsgood/google-signin-unity

Android was migrated to use CredentialManager and AuthorizationClient since GoogleSignInAccount was deprecated

However, GoogleIdTokenCredential actually not provide numeric unique ID anymore and set email as userId instead, so I have to extract jwt sub value from idToken (which seem like the same id as userId from GoogleSignIn of other platform)

Tested in unity 2021.3.21 and unity 6000.0.4

Add UPM dependency with branch tag https://github.com/Thaina/google-signin-unity.git#newmigration

  "dependencies": {
    "com.google.external-dependency-manager": "https://github.com/googlesamples/unity-jar-resolver.git?path=upm",

GoogleSignIn.Configuration ??= new GoogleSignInConfiguration()
{
    WebClientId = Env.GoogleWebClientId,
    RequestIdToken = true,
    UseGameSignIn = false,
    RequestEmail = true,
    HidePopups = true
};

var user = await DefaultInstance.SignInSilentlyAsync();

1. Dismissing the popup may sometimes prompt the following
   

2. The prompt is always shown, there is no 'silently' sign in. I cant see how to fix this

[Thaina]

@nixonjoshua98 I have push the new fix to allow auto signin for device with multiple account. But I just have found some detailed concern about this case

https://developer.android.com/identity/sign-in/credential-manager-siwg#enable-sign-in
https://stackoverflow.com/a/78269657/1260333

As there is mention about criteria to auto signin. Even we have auto signin for the device with multiple account, if there is also more than one account had ever signin to your app, the account selector will still be launched anyway in the same manner you have experienced

The stackoverflow answer above have mention that you might need to revoke access to the app from the account too, and have only one account connect to the app

I have just create google issue for request a feature to specified email hint (as the new identity signin system was not contain API to set a hint anymore). Would you pleased to upvote this issue too?

Much love, I've upvoted it. Thanks for the quick responses

Is there any update on 'silently' sign in ? @Thaina @nixonjoshua98

[nixonjoshua98]

I went with the approach of storing an encrypted token after signing in, which stores your login preference. Let's me skip the Google login popup, and I just send that token to my backend.

It should be silent if you have only one account signing in into your app in your device, isn't it?

[nivedhKA]

Yes, it's working and doesn't open dialog ui of account selecting but still encounter the following error in the logs during a slientlysignin :

NoCredentialException: During begin sign-in, failure response from one tap: 16: User disabled the feature

Upon researching this error, I discovered that it occurs when the Google account's sign-in prompt is disabled. Specifically, if a user has only one account signed in and has disabled the one-tap sign-in feature in their Google account settings, this error is generated. When I enabled the one-tap sign-in for the affected Google account, the error disappeared. However, the account selection dialog appears again.

Steps to Reproduce

1. Ensure only one Google account is signed into the device.
2. Disable the one-tap sign-in feature for this Google account in its settings.
3. Attempt to sign in silently using the app.
4. Observe the NoCredentialException error in the logs.
5. Enable the one-tap sign-in feature for the Google account.

6. Attempt to sign in silently again and notice that the account selection dialog appears once more.

[Thaina]

Based on your step, isn't those expected behaviour? Or are there other behaviour we should have?

[nixonjoshua98]

@nivedhKA Where is that setting, i can't seem to find it? I have this exception for a couple of users as well.

In Android Device -> Open Settings -> Find Google Account -> Select Google Account And Select -> Open Manage Account And Search Sign In prompts.

[Thaina]

@nivedhKA I think I just understand your issue

I think what you trying to do, which is disabling signinprompt, are not given what you expected

What I think it would is revoking the signin of the app from all of your accounts except one, which is difference thing from just disabling signin prompt

I am not testing it yet but maybe this might work

@Thaina Is there a unity package? Or how to build it.

to google
And please maintain it as soon as possible.

I don't know, I don't use unitypackage to the point I already forgot how to made it properly for package

I would like to also dissuade on using unitypackage. Are there any reason you cannot move on to use upm instead?

[o-osawa]

Thank you.
I was looking for how to use it and didn't know about UPM.
I understand that you need to put the git URL into Unity Package Manager. I'll try it.

ANY TIPS ?......

Edited :

New to GitHub !...
sorry for unwanted message !...

[Thaina]

@shiva30122 We need more log to investigate

and it surely will be some log around the silentsignin especially before popup occur

You need to understand the engineering process about how to debug your system on device. Or else no one can help you. Don't just throw random message around chaotically

About 2 clientID. You can write #if directive per platform by yourself

Refer My Video --> https://youtu.be/6DQGnQv-GL0

@shiva30122 There are 3 things I can think of
1 - you may not set HidePopups to true
2- See this comment > #256 (comment)
3 - You have already sign in with google with multiple account in that device. This was one problem of new version of Google credential manager and I can't do anything about it. It will insist to have popup because it was unsure which account you really want to use

[Thaina]

@shiva30122 Please investigate the criteria mention in this link to determine if your device's setting are not met any of it
