如何在Xamarin.Android应用程序上集成新的Google登录？

我正在尝试按照 Google’s instructions关于如何将新的Google登录(不是旧的Google登录)添加到我的Xamarin.Android应用程序中.对于我的生活,我找不到支持新登录系统的正确的Google Play服务NuGet包或Xamarin组件.

当我将以下代码添加到活动时,我得到“无法找到类型或命名空间’GoogleSignInoptions’.您是否缺少程序集引用？”构建错误.

// 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();

以下是项目中包含的Xamarin.GooglePlayServices NuGet包：

<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" />

Xamarin尚未支持新的Google登录系统,还是我错过了什么？

解决方法

启用预发布预设并搜索：

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>

C#版本为Integrating Google Sign-In into Your Android App

SignInButton button = 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 += delegate {
    signIn();
};
