Hello,
I'm trying to implement in the xamarin application the mechanism that already exists on the web for social logins. Is there an example about this or can you help me with some code instructions on how to implement this?
Thank you very much. Best Regards

Maybe I have not add an appropriate js file.
Can you please tell me exactly which js and css files I need to add so that I can get exactly the same result as the example https://preview.keenthemes.com/metronic/demo1/features/custom/accordions.html
Thank you in advance!
Hello,
I want to migrate my Xamarin application to the new MAUI project template. In Xamarin, I have a page view (xaml) with a map control bound to the view model Map property <ContentView HeightRequest="650" Content="{Binding Map}"/>
Now in MAUI, I am trying to create a new razor page but I do not know how to bind the MAUI Map control to the razor page.
I also tried to use xaml page but I had trouble navigating and couldn't set the menu item to go to the xaml page. Is this possible to use both razor pages and xaml pages in MAUI?
I would appreciate any help. Thank you in advance.
Hi ismcagdas,
The above code exists in the Host AuthConfigurer class.
Could you please have a look at the code in the project I am sharing with you in the link below?
https://mgcodegr.sharepoint.com/:u:/g/Ea22k-KFFlVNvWuhI6EnKk8BalPc2UlLMpV1XzjOlS3p_w?e=JpqahC
I have created in the mobile shared the service NotificationService and in the IncidentsViewModel I call the SendMessage which successfully sends the message and the web app receives it but I am not able to receive a message when I send it from the web app.
Thank you very much for your time and your help!
Hi ismcagdas,
Yes, the CreateHubUrl contains the enc_auth_token. Please see the screenshot below from the Host log.
I can send the message successfully from Xamarin to Web app but I cannot receive a message from Web app.
This is my code for the notification service:
public class NotificationService : ISingletonDependency, INotificationService
{
public HubConnection _HubConnection { get; }
private readonly IAccessTokenManager _accessTokenManager;
private bool _isConnecting;
public NotificationService(IAccessTokenManager accessTokenManager)
{
try
{
_accessTokenManager = accessTokenManager;
_HubConnection = new HubConnectionBuilder()
.WithUrl(CreateHubUrl(),
(opts) =>
{
opts.HttpMessageHandlerFactory = (message) =>
{
if (message is HttpClientHandler clientHandler)
// bypass SSL certificate
clientHandler.ServerCertificateCustomValidationCallback +=
(sender, certificate, chain, sslPolicyErrors) => { return true; };
return message;
};
}
)
.Build();
_HubConnection.Closed += TryToConnectIfNeeds;
}
catch (Exception ex)
{
ExceptionHandler.LogException(ex);
}
}
private async Task TryToConnectIfNeeds(Exception connectionException)
{
try
{
ExceptionHandler.LogException(connectionException);
if (!_accessTokenManager.IsUserLoggedIn)
{
return;
}
await Task.Delay(new Random().Next(0, 5) * 1000);
await _HubConnection.StartAsync();
}
catch (Exception ex)
{
ExceptionHandler.LogException(ex);
}
}
public async Task<bool> SendMessageAsync(string message)
{
if (!await ConnectAsync())
{
return false;
}
try
{
//find an existing user, I picked the user with Id:4
var messageData = new SendChatMessageInput
{
TenantId = 1,
TenancyName = "Default",
UserId = 2,
UserName = "admin",
Message = message
};
var response = await _HubConnection.InvokeAsync<string>("SendMessage", messageData);
if (string.IsNullOrEmpty(response))
{
Console.WriteLine(@"Message successfully sent!");
return true;
}
Console.WriteLine(@"Message failed to send: " + response);
return true;
}
catch (Exception ex)
{
ExceptionHandler.LogException(ex);
return false;
}
}
public async Task<bool> ConnectAsync()
{
_HubConnection.On<ChatMessageDto>("getChatMessage", (result) =>
{
Console.WriteLine("Helo");
});
try
{
if (_HubConnection.State == HubConnectionState.Connected)
{
return true;
}
if (_isConnecting)
{
return false;
}
_isConnecting = true;
await _HubConnection.StartAsync();
Console.WriteLine(@"Connected!");
return true;
}
catch (Exception ex)
{
ExceptionHandler.LogException(ex);
return false;
}
finally
{
_isConnecting = false;
}
}
public async Task<bool> DisconnectAsync()
{
try
{
if (_HubConnection.State == HubConnectionState.Disconnected)
{
return true;
}
await _HubConnection.StopAsync();
Console.WriteLine(@"Disconnected!");
return true;
}
catch (Exception ex)
{
ExceptionHandler.LogException(ex);
return false;
}
}
private string CreateHubUrl()
{
string accessToken = _accessTokenManager.AuthenticateResult.EncryptedAccessToken;
return ApiUrlConfig.BaseUrl +
AppConsts.SignalRChatHubPath.TrimStart('/') + "?" +
AppConsts.EncryptedAuthTokenQueryStringName + "=" +
Uri.EscapeDataString(accessToken);
}
}
Then inside a view model using a button I call the SendMessageAsync. I might be doing something wrong in how I call and what I call in the class NotificationService above.
Thank you very much for your help!
Hi m.aliozkaya,
Thank you very much for your help and your code.
I used the chathub and your code and I managed to send a message from xamarin to web mvc application and at the same time the On<ChatMessageDto> was called when I sent the message from Xamarin.
But when I send a chat message from the mvc web application then the xamarin application does not receive it. On web mvc application I can send a chat message from one user to another.
Please note that I do not use Angular but MVC.
Any help would be appreciated. Thank you once more!
Hi,
I created a new separate hub with a new signalr communicator similar to SignalRChatCommunicator. I modified the Startup with the new endpoint of the new hub. Also I created a new console application in order to test the code and subscribe to then event of the new hub. I manage to connect to the new hub (I checked the log for the connection id) running Host in Mobile profile but I cannot get the message.
I send a message to all clients of the hub using the code below await _incHub.Clients.All.SendAsync("getIncidentMessage", "test");
The code of the console application is `var hubConnection = new HubConnectionBuilder() .WithUrl("https://localhost:44301/inchub", (opts) => { opts.HttpMessageHandlerFactory = (message) => { if (message is HttpClientHandler clientHandler) // bypass SSL certificate clientHandler.ServerCertificateCustomValidationCallback += (sender, certificate, chain, sslPolicyErrors) => { return true; }; return message; }; } ) .Build();
hubConnection.On("getMessage", message => Console.WriteLine(message)); hubConnection.On("getIncidentMessage", message => Console.WriteLine(message)); hubConnection.On("App.NewIncident", message => Console.WriteLine(message)); hubConnection.StartAsync().Wait();`
Could you please provide a sample code like the code above that works with any message in default hub or chathub of the asp.net zero. If I had the implementation in Xamarin would be perfect.
I cannot find a solution that works.
Thank you one more time for your help.
Hi,
I have not change anything else about hub configuration. In Web.Host Startup.cs I have the default code. app.UseEndpoints(endpoints => { endpoints.MapHub<AbpCommonHub>("/signalr"); endpoints.MapHub<ChatHub>("/signalr-chat"); ... I may not have understood something correctly about how Notifications work. I have not implemented a separate hub. Do the notifications send a message to the AbpCommonHub signalr hub? If there was a sample or some code on how i can get them in xamarin application that would be great.
Thank you!
Hi,
and from Web.Host Logs I get DEBUG 2022-11-09 09:16:49,918 [29 ] Abp.AspNetCore.SignalR.Hubs.AbpCommonHub - A client is connected: {"ConnectionId":"OT1w2usalDZHMcb4OoyyCQ","IpAddress":"127.0.0.1","TenantId":1,"UserId":3,"ConnectTime":"2022-11-09T09:16:49.9163277+02:00","Properties":{}}
I send the notification using the below function in AppNotifier when I create a new object
public async Task NewIncidentAsync(Incident incident)
{
var notificationData = new MessageNotificationData("New " + incident.Criticality.ToString() + " " +
incident.Type.ToString() + " incident:" + incident.Description);
notificationData["description"] = incident.Description;
notificationData["type"] = incident.Type.ToString();
notificationData["critical"] = incident.Criticality.ToString();
notificationData["lat"] = incident.Latitude;
notificationData["lon"] = incident.Longitude;
notificationData["id"] = incident.Id;
await _notificationPublisher.PublishAsync(AppNotificationNames.NewIncident, notificationData,severity: NotificationSeverity.Warn);
}
but maybe I do something wrong in message subscription code.
HubConnection.On<string>(AppNotificationNames.NewIncident, (message) => { Console.WriteLine("TEST"); });
Thank you!

Hi,
I use notificationPublisher to send a notification to all users using the below code and it works for the web application.
await _notificationPublisher.PublishAsync(AppNotificationNames.NewIncident, notificationData,severity: NotificationSeverity.Warn);
But when I connect, using signalr, to abpcommonhub in xamarin application (connection established successfully based on
https://support.aspnetzero.com/QA/Questions/6841/Push-notification-implementation-in-Xamarin-Mobile-application) and subscribe to above notification message, I cannot receive it with the below hubconnection message subscription code.
HubConnection.On(AppNotificationNames.NewIncident, (message) => { Console.WriteLine("TEST"); });
Below is the code of NotificationService in Xamarin application.
public class NotificationService : ISingletonDependency, INotificationService { public HubConnection HubConnection { get; }

{
if (message is HttpClientHandler clientHandler)
// bypass SSL certificate
clientHandler.ServerCertificateCustomValidationCallback +=
(sender, certificate, chain, sslPolicyErrors) => { return true; };
return message;
};
}
)
.ConfigureLogging(logging => {
logging.SetMinimumLevel(LogLevel.Debug);
logging.AddConsole();
logging.AddDebug();
})
.Build();

Could you please help me?
