I am trying the sign in a user with the silent signin api.
First time a user opens the app iam singin in the user using Auth.GoogleSignInApi.getSignInResultFromIntent(data); where the user is prompted to choose a signin email.
Next time a need a renewed token, i try to get a token in the background, by using the Auth.GoogleSignInApi.silentSignIn(mGoogleApiClient);
code is as follows:
public void createNewToken(String serverKey, Context context) {
this.context = context;
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestIdToken(serverKey)
.requestEmail()
.requestProfile()
.build();
GoogleApiClient mGoogleApiClient = new GoogleApiClient.Builder(context)
.addOnConnectionFailedListener(this)
.addApi(Auth.GOOGLE_SIGN_IN_API, gso)
.addScope(new Scope(Scopes.PROFILE))
.addScope(new Scope(Scopes.EMAIL))
.build();
OptionalPendingResult<GoogleSignInResult> pendingResult = Auth.GoogleSignInApi.silentSignIn(mGoogleApiClient);
if (pendingResult.isDone()) {
handleResult(pendingResult.get());
} else {
pendingResult.setResultCallback(new ResultCallback<GoogleSignInResult>() {
#Override
public void onResult(#NonNull GoogleSignInResult result) {
handleResult(result);
}
});
}
}
However, the problem is i dont get any callback, either from isDone or in the callback(). no error are given except from this:
D/GoogleSignInApiImpl: getSavedSignInResultIfEligible
D/GoogleSignInApiImpl: trySilentSignIn
Am i dusing the api wrongly or why dosnt this work? thx for any feedback!
Try adding ".enableAutoManage(...)" when building the Google API client: developers.google.com/identity/sign-in/android
If you don't want to use enableAutoManage, because you are not in a FragmentActivity for example, you can call manually googleApiClient.connect() and disconnect.

I'm using firebase anonymous authantication for my unity project.
As i always did when project is started i'm sending request to firebase for authantication,
but on my last project (which uses firebase sdk 6.16.0) my request creates new user everytime.
Here is some code about how i'm sending my request
Firebase.Auth.FirebaseAuth auth = Firebase.Auth.FirebaseAuth.DefaultInstance;
auth.SignInAnonymouslyAsync().ContinueWith((task =>
{
if (task.IsCanceled)
{
Debug.Log("task cancelled");
return;
}
if (task.IsFaulted)
{
Debug.Log("task cancelled");
return;
}
if (task.IsCompleted)
{
Firebase.Auth.FirebaseUser userr = task.Result;
firebaseUserId = userr.UserId;
Debug.Log("firebaseUserId");
Debug.Log(firebaseUserId);
//every opening returns new uniq id here.
}
}));
On firebase authantication panel i only activated anonymous login. any suggestions?
Or is there any way to downgrade unity firebase version? i've tried to import old version which i was using on my last game (sdk 6.15.2) but there is some errors on resolver.
Basically, every time you call SignInAnonymouslyAsync you'll create a new user and the last one will be basically lost (it's more or less a random hash - anonymous as it's name suggests).
I'll typically do something like:
using System;
using Firebase.Auth;
using UnityEngine;
using UnityEngine.Events;
public class Login : MonoBehaviour
{
public UnityEvent OnSignInFailed = new UnityEvent();
public UserSignedInEvent OnUserSignedIn = new UserSignedInEvent();
public async void TriggerLogin()
{
var auth = FirebaseAuth.DefaultInstance;
var user = auth.CurrentUser;
if (user == null)
{
try
{
user = await auth.SignInAnonymouslyAsync();
}
catch (Exception e)
{
Debug.LogException(e);
OnSignInFailed.Invoke();
return;
}
}
// user definitely should not be null!
if (user == null)
{
OnSignInFailed.Invoke();
Debug.LogWarning("User still null!?");
return;
}
var userName = user.UserId;
OnUserSignedIn.Invoke(userName);
Debug.Log($"Logged in as {userName}");
}
[Serializable]
public class UserSignedInEvent : UnityEvent<string>
{
}
}
Note that for this code snippet, TriggerLogin is a public method so I can chain it off of a UnityEvent in the Unity editor.
Try and Put it some kind of check to find if used is already logged in. If yes, then do a silent login, if no then use anonymous login.
Currently you are straightaway logging in user even if they logged in last time they opened the Application.

I am trying to develop a xamarin forms app in which user can make call
(Navigate to dialer) from taping on number showed on app.In android I accomplished this through dependency service.But in ios I am stuck.I heard about callkit.I saw the documentation of it in https://learn.microsoft.com/en-us/xamarin/ios/platform/callkit?tabs=windows. But how can I actually implement on this in my App? I added all the classes in that document to my app.But how I can make the call from xamal.cs to the ios specified code? By using Dependency service?
Edit: I know how to navigate app to dialer or phone app. Why I am using callkit is I want to get the call duartion.
I created an Instance
public interface IosCallerDialer
{
void StartCall();
}
Implementation on ios
class IosCallDial: IosCallerDialer
{
private CXCallController CallController = new CXCallController();
private void SendTransactionRequest(CXTransaction transaction)
{
// Send request to call controller
CallController.RequestTransaction(transaction, (error) => {
// Was there an error?
if (error == null)
{
// No, report success
Console.WriteLine("Transaction request sent successfully.");
}
else
{
// Yes, report error
Console.WriteLine("Error requesting transaction: {0}", error);
}
});
}
public void StartCall()
{
// Build call action
string contact = "8547085532";
var handle = new CXHandle(CXHandleType.Generic, contact);
var startCallAction = new CXStartCallAction(new NSUuid(), handle);
// Create transaction
var transaction = new CXTransaction(startCallAction);
// Inform system of call request
SendTransactionRequest(transaction);
}
}
My xaml.cs
async void btnCall_Clicked(object sender, System.EventArgs e)
{
DependencyService.Get<IosCallerDialer>().StartCall();
}
Apart this I added all the classes defined in the document.I want only outgoing call. Is this proper way? I cant find any tutorials regarding callkit on xamarin. Any help is appreciated.
EDIT: I understand Callkit only for voip. So is there any other workaround like starting a timer when moves to phone app and stop timer when returns to app? Is it possible? Please provide any insights.
You can try the code below to detect the state of incoming call.
public partial class AppDelegate : global::Xamarin.Forms.Platform.iOS.FormsApplicationDelegate
{
//
// This method is invoked when the application has loaded and is ready to run. In this
// method you should instantiate the window, load the UI into it and then make the window
// visible.
//
// You have 17 seconds to return from this method, or iOS will terminate your application.
//
public CTCallCenter c { get; set; }
public override bool FinishedLaunching(UIApplication app, NSDictionary options)
{
global::Xamarin.Forms.Forms.Init();
LoadApplication(new App());
c = new CTCallCenter();
c.CallEventHandler = delegate (CTCall call)
{
if (call.CallState == call.StateIncoming)
{
//start the timer
}
else if (call.CallState == call.StateDialing)
{
}
else if (call.CallState == call.StateConnected)
{
}
else if(call.CallState == call.StateDisconnected)
{
//end the timer
//use messagecenter to send duartion
MessagingCenter.Send<Object>(new Object(), "Hi");
}
};
return base.FinishedLaunching(app, options);
}
}
And any Where in Xamarin.forms:
MessagingCenter.Subscribe<Object>(this, "Hi", (sender) => {
// do something whenever the "Hi" message is sent
Console.WriteLine("hihihi");
});
Note: I haven't test it on my side yet as I don't have enough device. You can test it and let me know if it works.
I'm trying to check which page should load my app at the beginning, first of all I check a database table if I find the login information stored I want to push the once named StartPage(), as I'm working with the database the method includes an await if there isn't any data stored I want to push the LoginPage(). I have tried following this example Xamarin.Forms Async Task On Startup . My code is :
public App()
{
int result;
InitializeComponent();
ThreadHelper.Init(SynchronizationContext.Current);
ThreadHelper.RunOnUIThread(async () => {
MainPage = new ActivityIndicatorPage();
result = await InitializeAppAsync();
if (result == 0)
{
PushLoginPage();
}
else
{
PushStartPage();
}
});
}
public void PushStartPage()
{
NavigationPage nav = new NavigationPage(new StartPage());
nav.SetValue(NavigationPage.BarBackgroundColorProperty, Color.FromHex("#D60000"));
MainPage = nav;
}
public void PushLoginPage()
{
MainPage = new Login();
}
public void PushLoginPage(string email, string password)
{
MainPage = new Login(email, password);
}
private async Task<int> InitializeAppAsync()
{
if (ViewModel == null)
ViewModel = new MainViewModel(this);
return await ViewModel.LoginViewModel.PushInitialPage();
}
But throws the following exception and as the author of the article says, is not recommended to do it.
Exception
Another option tried was overriding the OnStart() method but didn't work either.
protected override async void OnStart()
{
Task.Run(async ()=> { await InitializeAppAsync(); });
}
The PushInitialPage method:
public async Task PushInitialPage()
{
if (_app.Properties.ContainsKey("isLogged"))
{
var user = await UserDataBase.GetUserDataAsync();
var result = await Login(user.Email, user.Password);
if (result.StatusCode != 200)
{
return 0;
///PushLoginPage();
}
else
{
return 1;
//PushStartPage();
}
}
else
{
return 0;
}
}
When the OS asks your app to show a page, it must show a page. It can't say "hold on a minute or two while I talk to this remote server over an iffy network connection." It has to show a page Right Now.
So, I recommend bringing up a splash page - your company or app logo, for example. When the splash page shows, then call InitializeAppAsync, and based on the result, switch to the login or start page or nice user-friendly offline error page.
In Xamarin.Forms we have properties called 'Application.Current.Properties'. By using this we can able to save the any data type. So once user login in to the application you can set one flag and set it is true. Then after every time when user login in to the application you can check this flag and navigate your respective page.
Sample Code :
App.cs :
public App()
{
if (Current.Properties.ContainsKey("isLogged"))
{
if((bool)Application.Current.Properties["isLogged"])
{
// navigate to your required page.
}
else
{
// naviate to login page.
}
}
else
{
// naviate to login page.
}
}
At first time application open it checks the 'isLogged' property is presented or not, if not it will move to the login page. When user login into the application by using his credentials, we need to create 'isLoggin' property and set as true. Then after if user try to login it checks the condition and navigates to the respective page.
Saving Property SampleCode :
Application.Current.Properties["isLogged"] = true;
await Application.Current.SavePropertiesAsync();
write above code for after login into the application. If a user log out from the app you need to set 'isLogged' flag is false.
I am using Android Firebase Auth Ui for providing Phone Number based sign in option in an android app. I am trying to provide an additional option to signed in users to switch their signed in phone number to another number keeping the same user account.
But as per Firebase Docs for Phone number there are no options to change the signed in number.
There are options for linking different auth providers like email, google or Facebook login etc to same account. But there is no way mentioned about how to change the phone number or email id keeping the same user id.
Is there a workaround or method by which we can achieve this?
An API exists for updating the phone number of a current user: FirebaseUser#updatePhoneNumber(PhoneAuthCredential credential)
I also had this challenge to update user phone number and when I go on documentation I got something by using I have done this task.
you can go for documentation by click here
Now the method you can use : - for java android project.
PhoneAuthCredential phoneAuthCredential = PhoneAuthProvider.getCredential( "+91-98298XXXX2", "OTP_CODE" );
// Update Mobile Number...
firebaseAuth.getCurrentUser().updatePhoneNumber(phoneAuthCredential)
.addOnCompleteListener(new OnCompleteListener <Void>() {
#Override
public void onComplete(#NonNull Task <Void> task) {
if (task.isSuccessful()) {
// Update Successfully
} else {
// Failed
}
}
}
);
val options = PhoneAuthOptions.newBuilder(FirebaseAuth.getInstance())
.setPhoneNumber(phoneNumber) // Phone number to verify
.setTimeout(100L, TimeUnit.SECONDS) // Timeout and unit
.setActivity(activity) // Activity (for callback binding)
.setCallbacks(returnCallBack()) // OnVerificationStateChangedCallbacks
.build()
PhoneAuthProvider.verifyPhoneNumber(options)
private fun returnCallBack() = object : PhoneAuthProvider
.OnVerificationStateChangedCallbacks() {
override fun onVerificationCompleted(credential: PhoneAuthCredential) {
FirebaseAuth.getCurrentUser()?.updatePhoneNumber(credential)
}
override fun onVerificationFailed(e: FirebaseException) {
// This callback is invoked in an invalid request for verification is made,
// for instance if the the phone number format is not valid.
Log.e("phone", e.toString())
}
override fun onCodeSent(verificationId: String, token: PhoneAuthProvider.ForceResendingToken) {
//You need this to pass as a parameter for the update method call.
vericationSent = verificationId
}
}
fun confirmChange(code: String, context: Context?) {
if(code.contains(Regex(onlyNumber))) {
Log.d("codeSent" , "Right code : $code")
FirebaseAuth.getCurrentUser()
?.updatePhoneNumber(PhoneAuthProvider.getCredential(vericationSent, code))
?.addOnCompleteListener {task ->
//it worked if you reach here.
}?.addOnFailureListener {
//Show the error to user
}
}
vericationSent = EMPTY
} else {
Log.d("codeSent" , "wrong code : $code")
}
}
Try this
//Send otp to phone number
String verificationId;
private void startLoginFirebase(){
PhoneAuthProvider.getInstance(firebaseAuth).verifyPhoneNumber(phone, 90L, TimeUnit.SECONDS, PhoneAuthActivity.this, new PhoneAuthProvider.OnVerificationStateChangedCallbacks() {
#Override
public void onCodeSent(#NonNull String s, #NonNull PhoneAuthProvider.ForceResendingToken forceResendingToken) {
super.onCodeSent(s, forceResendingToken);
verificationId = s;
updatePhoneNum();
}
#Override
public void onCodeAutoRetrievalTimeOut(#NonNull String s) {
super.onCodeAutoRetrievalTimeOut(s);
}
#Override
public void onVerificationCompleted(#NonNull PhoneAuthCredential phoneAuthCredential) {
}
#Override
public void onVerificationFailed(#NonNull FirebaseException e) {
processFurther(e.getLocalizedMessage().toString(), 0);
}
});
}
//Verify Otp
private void updatePhoneNum(){
PhoneAuthCredential phoneAuthCredential = PhoneAuthProvider.getCredential(verificationId, otp);
firebaseAuth.getCurrentUser().updatePhoneNumber(phoneAuthCredential).addOnCompleteListener(new OnCompleteListener<Void>() {
#Override
public void onComplete(#NonNull Task<Void> task) {
}
});
}
Apparently - according to the project maintainers - FirebaseUI-Android doesn't support this feature, and it looks like they have no plans of doing it any time soon :(
In the latest version of Asp.Net SignalR, was added a new way of sending a message to a specific user, using the interface "IUserIdProvider".
public interface IUserIdProvider
{
string GetUserId(IRequest request);
}
public class MyHub : Hub
{
public void Send(string userId, string message)
{
Clients.User(userId).send(message);
}
}
My question is: How do I know to whom I am sending my message? The explanation of this new method is very superficial. And the draft Statement of SignalR 2.0.0 with this bug and does not compile. Has anyone implemented this feature?
More Info : http://www.asp.net/signalr/overview/signalr-20/hubs-api/mapping-users-to-connections#IUserIdProvider
Hugs.
SignalR provides ConnectionId for each connection. To find which connection belongs to whom (the user), we need to create a mapping between the connection and the user. This depends on how you identify a user in your application.
In SignalR 2.0, this is done by using the inbuilt IPrincipal.Identity.Name, which is the logged in user identifier as set during the ASP.NET authentication.
However, you may need to map the connection with the user using a different identifier instead of using the Identity.Name. For this purpose this new provider can be used with your custom implementation for mapping user with the connection.
Example of Mapping SignalR Users to Connections using IUserIdProvider
Lets assume our application uses a userId to identify each user. Now, we need to send message to a specific user. We have userId and message, but SignalR must also know the mapping between our userId and the connection.
To achieve this, first we need to create a new class which implements IUserIdProvider:
public class CustomUserIdProvider : IUserIdProvider
{
public string GetUserId(IRequest request)
{
// your logic to fetch a user identifier goes here.
// for example:
var userId = MyCustomUserClass.FindUserId(request.User.Identity.Name);
return userId.ToString();
}
}
The second step is to tell SignalR to use our CustomUserIdProvider instead of the default implementation. This can be done in the Startup.cs while initializing the hub configuration:
public class Startup
{
public void Configuration(IAppBuilder app)
{
var idProvider = new CustomUserIdProvider();
GlobalHost.DependencyResolver.Register(typeof(IUserIdProvider), () => idProvider);
// Any connection or hub wire up and configuration should go here
app.MapSignalR();
}
}
Now, you can send message to a specific user using his userId as mentioned in the documentation, like:
public class MyHub : Hub
{
public void Send(string userId, string message)
{
Clients.User(userId).send(message);
}
}
Here's a start.. Open to suggestions/improvements.
Server
public class ChatHub : Hub
{
public void SendChatMessage(string who, string message)
{
string name = Context.User.Identity.Name;
Clients.Group(name).addChatMessage(name, message);
Clients.Group("2#2.com").addChatMessage(name, message);
}
public override Task OnConnected()
{
string name = Context.User.Identity.Name;
Groups.Add(Context.ConnectionId, name);
return base.OnConnected();
}
}
JavaScript
(Notice how addChatMessage and sendChatMessage are also methods in the server code above)
$(function () {
// Declare a proxy to reference the hub.
var chat = $.connection.chatHub;
// Create a function that the hub can call to broadcast messages.
chat.client.addChatMessage = function (who, message) {
// Html encode display name and message.
var encodedName = $('<div />').text(who).html();
var encodedMsg = $('<div />').text(message).html();
// Add the message to the page.
$('#chat').append('<li><strong>' + encodedName
+ '</strong>: ' + encodedMsg + '</li>');
};
// Start the connection.
$.connection.hub.start().done(function () {
$('#sendmessage').click(function () {
// Call the Send method on the hub.
chat.server.sendChatMessage($('#displayname').val(), $('#message').val());
// Clear text box and reset focus for next comment.
$('#message').val('').focus();
});
});
});
Testing
This is how use SignarR in order to target a specific user (without using any provider):
private static ConcurrentDictionary<string, string> clients = new ConcurrentDictionary<string, string>();
public string Login(string username)
{
clients.TryAdd(Context.ConnectionId, username);
return username;
}
// The variable 'contextIdClient' is equal to Context.ConnectionId of the user,
// once logged in. You have to store that 'id' inside a dictionaty for example.
Clients.Client(contextIdClient).send("Hello!");
Look at SignalR Tests for the feature.
Test "SendToUser" takes automatically the user identity passed by using a regular owin authentication library.
The scenario is you have a user who has connected from multiple devices/browsers and you want to push a message to all his active connections.
Old thread, but just came across this in a sample:
services.AddSignalR()
.AddAzureSignalR(options =>
{
options.ClaimsProvider = context => new[]
{
new Claim(ClaimTypes.NameIdentifier, context.Request.Query["username"])
};
});
For anyone trying to do this in asp.net core. You can use claims.
public class CustomEmailProvider : IUserIdProvider
{
public virtual string GetUserId(HubConnectionContext connection)
{
return connection.User?.FindFirst(ClaimTypes.Email)?.Value;
}
}
Any identifier can be used, but it must be unique. If you use a name identifier for example, it means if there are multiple users with the same name as the recipient, the message would be delivered to them as well. I have chosen email because it is unique to every user.
Then register the service in the startup class.
services.AddSingleton<IUserIdProvider, CustomEmailProvider>();
Next. Add the claims during user registration.
var result = await _userManager.CreateAsync(user, Model.Password);
if (result.Succeeded)
{
await _userManager.AddClaimAsync(user, new Claim(ClaimTypes.Email, Model.Email));
}
To send message to the specific user.
public class ChatHub : Hub
{
public async Task SendMessage(string receiver, string message)
{
await Clients.User(receiver).SendAsync("ReceiveMessage", message);
}
}
Note: The message sender won't be notified the message is sent. If you want a notification on the sender's end. Change the SendMessage method to this.
public async Task SendMessage(string sender, string receiver, string message)
{
await Clients.Users(sender, receiver).SendAsync("ReceiveMessage", message);
}
These steps are only necessary if you need to change the default identifier. Otherwise, skip to the last step where you can simply send messages by passing userIds or connectionIds to SendMessage. For more
