Iam尝试在我的Xamarin Android应用程序中实施Google+登录。我刚刚获得了一个显示Google + -Button for SignIn的活动。但是ApiClient永远不会抛出OnConnected Callback。
我实现了接口：
GoogleApiClient.IConnectionCallbacks, GoogleApiClient.IOnConnectionFailedListener
在OnCreate中，我初始化Google-Stuff：
var googleLogin = FindViewById<SignInButton>(Resource.Id.google_login);
googleLogin.SetSize(SignInButton.SizeWide);
googleLogin.Click += GoogleLogin_Click;
_googleApiClient = new GoogleApiClient.Builder(this)
.AddConnectionCallbacks(this)
.AddOnConnectionFailedListener(this)
.AddApi(PlusClass.API)
.AddScope(new Scope(Scopes.Profile))
.Build();
如果有人点击Google-SignIn i，请致电以下网址：
private void GoogleLogin_Click(object sender, System.EventArgs e)
{
_googleApiClient.Connect();
}
然后我想我可以通过这种方式获取用户信息：
public void OnConnected(Bundle connectionHint)
{
var people = PlusClass.PeopleApi.GetCurrentPerson(_googleApiClient);
}
提示：如果有人知道如何以现代方式解决这个问题，请将GetCurrentPerson标记为已弃用，请告诉我：）
在OnStop（）中，我只是断开客户端。但我的问题是OnConnected永远不会被调用。我错过了什么吗？我肯定在开发者控制台中注册了应用程序。这有几个主题，但到目前为止没有任何帮助:(

尝试将范围更改为DriveClass.ScopeFile：
_googleApiClient = new GoogleApiClient.Builder(Application.Context)
.UseDefaultAccount()
.AddConnectionCallbacks(this)
.AddOnConnectionFailedListener(this)
.AddApi(PlusClass.API)
.AddScope(PlusClass.ScopePlusLogin)
.Build();
应Connect拨打OnConnectionFailed来回拨打ConnectionResult来回拨打OnConnected，然后在用户选择帐户后登录public class MainActivity : Activity, GoogleApiClient.IConnectionCallbacks, GoogleApiClient.IOnConnectionFailedListener
{
GoogleApiClient client;
bool _resolvingError;
const string TAG = "MyGPlus";
const int REQUEST_RESOLVE_ERROR = 999;
public void OnConnected(Bundle connectionHint)
{
Log.Debug(TAG, "OnConnected");
}
public void OnConnectionFailed(ConnectionResult result)
{
Log.Debug(TAG, "OnConnectionFailed");
if (_resolvingError)
return;
if (result.HasResolution)
{
try
{
_resolvingError = true;
result.StartResolutionForResult(this, REQUEST_RESOLVE_ERROR);
}
catch (IntentSender.SendIntentException e)
{
Log.Debug(TAG, e.Message);
client.Connect();
}
}
else
{
ShowErrorDialog(result.ErrorCode);
}
}
void ShowErrorDialog(int errorCode)
{
var dialogFragment = new ErrorDialogFragment();
var args = new Bundle();
args.PutInt("dialog_error", errorCode);
dialogFragment.Arguments = args;
dialogFragment.Show(FragmentManager, "errordialog");
}
public void OnConnectionSuspended(int cause)
{
Log.Debug(TAG, "OnConnectionSuspended");
}
protected override void OnActivityResult(int requestCode, Result resultCode, Android.Content.Intent data)
{
base.OnActivityResult(requestCode, resultCode, data);
if (requestCode == REQUEST_RESOLVE_ERROR)
{
if (resultCode == Result.Ok)
{
if (!client.IsConnecting && !client.IsConnected)
{
client.Connect();
}
}
else if (resultCode == Result.Canceled)
{
Log.Debug(TAG, "Result.Canceled");
}
}
}
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
SetContentView(Resource.Layout.Main);
Button button = FindViewById<Button>(Resource.Id.myButton);
button.Click += delegate
{
client = new GoogleApiClient.Builder(Application.Context)
.UseDefaultAccount() .EnableAutoManage()
.AddConnectionCallbacks(this)
.AddOnConnectionFailedListener(this)
.AddApi(PlusClass.API)
.AddScope(PlusClass.ScopePlusLogin)
.Build();
_resolvingError = false;
client.Connect();
};
}
}
即可。称为...
