如何将新的Google Sign-In集成到Xamarin.Android应用程序中？ [英] How do you integrate the new Google Sign-In on a Xamarin.Android app?

问题描述

我试图遵循 Google的说明，了解如何将新的Google Sign-In（不是旧的Google+登录）添加到我的Xamarin.Android应用程序中。对于我而言，我无法找到支持新登录系统的正确Google Play服务NuGet包或Xamarin组件。

当我将以下代码添加到该活动，我得到无法找到类型或名称空间'GoogleSignInOptions'。您是否缺少程序集引用？

  // //配置登录以请求用户的ID，电子邮件地址和基本
 //个人资料。 ID和基本配置文件包含在DEFAULT_SIGN_IN中。 
 GoogleSignInOptions gso = new GoogleSignInOptions.Builder（GoogleSignInOptions.DEFAULT_SIGN_IN）.requestEmail（）。build（）; 
  

以下是包含在项目中的Xamarin.GooglePlayServices NuGet包：

 < package id =Xamarin.GooglePlayServices.Adsversion =27.0.0.0targetFramework =MonoAndroid50/ > 
< package id =Xamarin.GooglePlayServices.Analyticsversion =27.0.0.0targetFramework =MonoAndroid50/> 
< package id =Xamarin.GooglePlayServices.AppIndexingversion =27.0.0.0targetFramework =MonoAndroid50/> 
< package id =Xamarin.GooglePlayServices.Baseversion =27.0.0.0targetFramework =MonoAndroid50/> 
< package id =Xamarin.GooglePlayServices.Basementversion =27.0.0.0targetFramework =MonoAndroid50/> 
< package id =Xamarin.GooglePlayServices.Identityversion =27.0.0.0targetFramework =MonoAndroid50/> 
< package id =Xamarin.GooglePlayServices.Locationversion =27.0.0.0targetFramework =MonoAndroid50/> 
< package id =Xamarin.GooglePlayServices.Mapsversion =27.0.0.0targetFramework =MonoAndroid50/> 
< package id =Xamarin.GooglePlayServices.Plusversion =27.0.0.0targetFramework =MonoAndroid50/> 
  

Xamarin还不支持新的Google Sign-In系统吗？还是我错过了一些东西？

解决方案

启用预发布的工具并搜索： Xamarin.GooglePlayServices.Identity 29.0.0-beta1


packages.config：

 < packages> 
< package id =Xamarin.Android.Support.v4version =23.1.1.0targetFramework =MonoAndroid44/> 
< package id =Xamarin.GooglePlayServices.Authversion =29.0.0-beta1targetFramework =MonoAndroid44/> 
< package id =Xamarin.GooglePlayServices.Baseversion =29.0.0-beta1targetFramework =MonoAndroid44/> 
< package id =Xamarin.GooglePlayServices.Basementversion =29.0.0-beta1targetFramework =MonoAndroid44/> 
< package id =Xamarin.GooglePlayServices.Identityversion =29.0.0-beta1targetFramework =MonoAndroid44/> 
< / packages> 
  

  SignInButton按钮= FindViewById< SignInButton> （Resource.Id.sign_in_button）; 
 gso = new GoogleSignInOptions.Builder（GoogleSignInOptions.DefaultSignIn）
 .RequestEmail（）
 .Build（）; 
 mGoogleApiClient = new GoogleApiClient.Builder（this）
 .EnableAutoManage（mLoginFragment，failedHandler）
 .AddApi（Auth.GOOGLE_SIGN_IN_API）
 .Build（）; 
 button.Click + =委托{
 signIn（）; 
}; 
  

I am attempting to follow Google's instructions on how to add the new Google Sign-In (not the old Google+ Sign-In) to my Xamarin.Android app. For the life of me, I cannot find the correct Google Play Services NuGet package or Xamarin component that supports the new sign-in system.

When I add the following code to the activity, I get "The type or namespace 'GoogleSignInOptions' could not be found. Are you missing an assembly reference?" build error.

// 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().build();

Here are the Xamarin.GooglePlayServices NuGet packages that are include in the project:

<package id="Xamarin.GooglePlayServices.Ads" version="27.0.0.0" targetFramework="MonoAndroid50" />
<package id="Xamarin.GooglePlayServices.Analytics" version="27.0.0.0" targetFramework="MonoAndroid50" />
<package id="Xamarin.GooglePlayServices.AppIndexing" version="27.0.0.0" targetFramework="MonoAndroid50" />
<package id="Xamarin.GooglePlayServices.Base" version="27.0.0.0" targetFramework="MonoAndroid50" />
<package id="Xamarin.GooglePlayServices.Basement" version="27.0.0.0" targetFramework="MonoAndroid50" />
<package id="Xamarin.GooglePlayServices.Identity" version="27.0.0.0" targetFramework="MonoAndroid50" />
<package id="Xamarin.GooglePlayServices.Location" version="27.0.0.0" targetFramework="MonoAndroid50" />
<package id="Xamarin.GooglePlayServices.Maps" version="27.0.0.0" targetFramework="MonoAndroid50" />
<package id="Xamarin.GooglePlayServices.Plus" version="27.0.0.0" targetFramework="MonoAndroid50" />

Is the new Google Sign-In system not yet supported on Xamarin or am I missing something?

解决方案

Enable pre-release nugets and search for:

Xamarin.GooglePlayServices.Identity 29.0.0-beta1

packages.config:

<packages>
  <package id="Xamarin.Android.Support.v4" version="23.1.1.0" targetFramework="MonoAndroid44" />
  <package id="Xamarin.GooglePlayServices.Auth" version="29.0.0-beta1" targetFramework="MonoAndroid44" />
  <package id="Xamarin.GooglePlayServices.Base" version="29.0.0-beta1" targetFramework="MonoAndroid44" />
  <package id="Xamarin.GooglePlayServices.Basement" version="29.0.0-beta1" targetFramework="MonoAndroid44" />
  <package id="Xamarin.GooglePlayServices.Identity" version="29.0.0-beta1" targetFramework="MonoAndroid44" />
</packages>
