正在获取ResultCode结果.已取消OnActivityGoogle登录+xamarin.android中的活动结果

Question

在我当前的项目中，我的一名团队成员在Xamarin中实现了谷歌登录。安卓应用程序。他还添加了keystore和sha以供发布。在调试模式下，它在他的机器中运行良好。

但当我尝试从我的机器上运行这些代码时，我总是得到ResultCodeResult。Canceled OnActivity活动结果

这是我的android渲染器代码：

public class GoogleLoginRendere : PageRenderer, 
GoogleApiClient.IOnConnectionFailedListener, Android.Views.View.IOnClickListener
{
GoogleApiClient mGoogleApiClient;
MainActivity activity;
SignInButton signInButton;
Android.Widget.Button btn;
public GoogleLoginRendere()
{
}
public void OnConnectionFailed(ConnectionResult result)
{
throw new NotImplementedException();
}
protected override void OnElementChanged(ElementChangedEventArgs<Page> e)
{
base.OnElementChanged(e);
activity = Context as MainActivity;
if (e.OldElement != null)
{
activity.ActivityResult -= HandleActivityResult;
}
if (e.NewElement != null)
{
activity.ActivityResult += HandleActivityResult;
}
btn = new Android.Widget.Button(activity);
btn.Text = "Google SignIn";
signInButton = new SignInButton(activity);
signInButton.SetSize(SignInButton.SizeStandard);
signInButton.Visibility = ViewStates.Visible;
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DefaultSignIn)
.RequestEmail()
.Build();
mGoogleApiClient = new GoogleApiClient.Builder(activity)
.EnableAutoManage(activity /* FragmentActivity */, this /* OnConnectionFailedListener */)
.AddApi(Auth.GOOGLE_SIGN_IN_API, gso)
.Build();
FrameLayout.LayoutParams linLayoutParam = new FrameLayout.LayoutParams(LayoutParams.WrapContent, LayoutParams.WrapContent);
linLayoutParam.Gravity = GravityFlags.Center;
activity.AddContentView(btn, linLayoutParam);
btn.SetOnClickListener(this);
/* signInButton.Click += (sender, ex) =>
{
Console.WriteLine(string.Format("Click called"));
Intent signInIntent = Auth.GoogleSignInApi.GetSignInIntent(mGoogleApiClient);
activity.StartActivityForResult(signInIntent, 0);
};*/
MessagingCenter.Subscribe<object, string>(this, "CallLogout", (sender, msg) =>
{
Auth.GoogleSignInApi.SignOut(mGoogleApiClient);
signInButton.Visibility = ViewStates.Visible;
});
}
private void HandleActivityResult(object sender, ActivityResultEventArgs e)
{
Console.WriteLine(string.Format("renderer called"));
if (e.RequestCode == 0)
{
GoogleSignInResult result = Auth.GoogleSignInApi.GetSignInResultFromIntent(e.Data);
if (result.IsSuccess)
{
signInButton.Visibility = ViewStates.Invisible;
User aUser = new User();
aUser.Email = result.SignInAccount.Email;
App.appUser = aUser;
MessagingCenter.Send<object, string>(this, "callLoginWebservice", "callLoginWebservice");
}
else
{
Toast.MakeText(activity, "email not found", ToastLength.Long).Show();
Auth.GoogleSignInApi.SignOut(mGoogleApiClient);
signInButton.Visibility = ViewStates.Visible;
}
}
}
public void OnClick(Android.Views.View v)
{
var signInIntent = Auth.GoogleSignInApi.GetSignInIntent(mGoogleApiClient);
activity.StartActivityForResult(signInIntent, 0);
//Intent signInIntent = Auth.GoogleSignInApi.GetSignInIntent(mGoogleApiClient);
//((MainActivity)Forms.Context).StartActivityForResult(signInIntent, 1);
//mGoogleApiClient.Connect();
}
}

主要活动.cs

public class ActivityResultEventArgs : EventArgs
{
public int RequestCode { get; set; }
public Result ResultCode { get; set; }
public Intent Data { get; set; }
public ActivityResultEventArgs() : base()
{ }
}
[Activity(Label = "AppName.Droid", Icon = "@drawable/icon", Theme = "@style/MyTheme", ConfigurationChanges = ConfigChanges.ScreenSize | ConfigChanges.Orientation)]
public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity 
{
public event EventHandler<ActivityResultEventArgs> ActivityResult = delegate { };
protected override void OnCreate(Bundle bundle)
{
TabLayoutResource = Resource.Layout.Tabbar;
ToolbarResource = Resource.Layout.Toolbar;
App.ServiceManager = new SoapServiceManager(new SoapService());
base.OnCreate(bundle);
global::Xamarin.Forms.Forms.Init(this, bundle);
LoadApplication(new App());
}
protected override void OnActivityResult(int requestCode, Result resultCode, Intent data)
{
base.OnActivityResult(requestCode, resultCode, data);
Console.WriteLine(string.Format("Main activity result called"));
GoogleSignInResult result = Auth.GoogleSignInApi.GetSignInResultFromIntent(data);
if (result != null)
{
if (result.IsSuccess)
{
Console.WriteLine(string.Format("Activity result is {0}", result.SignInAccount.Email));
}
else
{
Console.WriteLine(string.Format("Activity result is {0}", resultCode));
}
}
ActivityResult(this, new ActivityResultEventArgs
{
RequestCode = requestCode,
ResultCode = resultCode,
Data = data
});
}
}  

我知道代码中没有任何问题，一定有一些配置问题。所以我尝试过的是

=>生成SSH-1密钥并添加到谷歌登录帐户中，并替换了谷歌services.json

=>尝试在我的帐户中创建新的谷歌登录项目。通过分发应用程序生成的新密钥库。

什么都没用。但我还是犯了同样的错误。

p。S：不要将其标记为重复答案。我搜索了所有其他问题，并在R&D，但找不到解决方案。这个ques看起来像我的。但它适用于android工作室中的javaandroid。所以并不是所有提到的文件都在Xamarin。安卓解决方案。

如果有人知道的话。帮帮我。

Answer 1

我的猜测是，你让谷歌管理你的应用程序签名密钥，这是谷歌Play中的一个选项。因此，你为发布配置文件生成的SHA1密钥是无用的，因为谷歌在生产中用不同的密钥为你的应用程序签名。

如果是这样的话，那么你应该转到Google Play控制台->发布管理->应用程序签名，并将你在那里找到的SHA1指纹添加到Firebase中，并生成一个新的包含该密钥的Google-services.json。

我希望这能帮助
