I have been using FontAwesome fonts in my app for about a year without any problems. Now, whenever I create a release build of the app, all I get are question marks instead of the icons. If I create a debug build to install on the phone or I run a release build on the simulator everything is fine. I have not changed any of the relevant declaration or definitions.
How can I fix this?
I am trying to implement an epub viewer in xamarin forms like the below video.
Video Link: https://drive.google.com/file/d/1jW33lstCXqwC35siYklLoXAxItWpQG8c/view?usp=sharing
At first, I need to show the TOC of the book. If taps any chapter in TOC need to show that chapter on the UI. The total chapters and current chapter details are added at the bottom of the page. We can change the font size, font style, light and dark theme, and horizontal and vertical swiping features. Also able to hear the chapter in audio voice. Please have a look at the above video.
This is the native Android implementation. I need to do this feature in xamarin forms, following are my queries.
Hi
I have a strange problem. I want to play notification sounds when app is active, and when in background too, but now, i dont know why the custom sounds played only when app is in background.
Here is my code
var content = new UNMutableNotificationContent
{
Title = title,
Subtitle = "",
Body = message
};
if (!string.IsNullOrEmpty(soundFileName))
content.Sound = UNNotificationSound.GetSound(soundFileName);
var trigger = UNTimeIntervalNotificationTrigger.CreateTrigger(0.01, false);
var request = UNNotificationRequest.FromIdentifier(messageId.ToString(), content, trigger);
UNUserNotificationCenter.Current.AddNotificationRequest(request, err =>
{
if (err != null) throw new Exception($"Failed to schedule notification: {err}");
});
What can i do to play sounds always?
Hi. I'm trying to pass a List from one view to another, using the MVVM pattern. In my project, I want to store the questions from a List (questions) into another list (errores) and I want to display "errores" in another view. Basically, whenever the wrong True/False button is pressed, I want to store the question into "errores".
Here's what I've tried:
{
private List<string> errores;
public RESULTSPAGE2(List<string> errores)

InitializeComponent();
MainListView.ItemsSource = errores;

Hi all,
I use PDFSharp.Xamarin.Forms in my app (Android and iOS). I initiated the package in MainActiviy.cs:
This works in general, but sometimes I get a strange error which causes my app to crash:
System.InvalidOperationException: PdfSharp.Xamarin.Forms already initialized before
Where does this error come from and how to solve this?
Hi Everyone, Help please! 
This is an accessibility question, and I can't seem to figure out the best way to go about it.

Hi,
My question is about how we can highlight the captured image,
please help me to solve this issue.
I'm a newbie to Xamarin and i try to learn how to call Web API's from Xamarin Forms. I was trying to run this example https://docs.microsoft.com/en-us/samples/xamarin/xamarin-forms-samples/webservices-todorest/ , at my Android Phone(Visual Studio Debugger), but i am getting a System.NotImplementedException in this methode:
[assembly: Dependency(typeof(HttpClientHandlerService))]
namespace TodoREST.Droid
{
public class HttpClientHandlerService : IHttpClientHandlerService
{
public HttpClientHandler GetInsecureHandler()
{
HttpClientHandler handler = new HttpClientHandler();
handler.ServerCertificateCustomValidationCallback = (message, cert, chain, errors) =>
{
if (cert.Issuer.Equals("CN=localhost"))
return true;
return errors == System.Net.Security.SslPolicyErrors.None;
};
return handler;
}
}
}
The exception occurs at this line:
handler.ServerCertificateCustomValidationCallback = (message, cert, chain, errors) =>
{
if (cert.Issuer.Equals("CN=localhost"))
return true;
return errors == System.Net.Security.SslPolicyErrors.None;
};
Can anyone help me with this?
Thanks in advance.
This Exception occurs when I push a button so many time in a short time. Why this happen? If I do it slow, giving some time between press and press it everything is alright. The problem is if you do it quickly. It's about two button, one to increase (+) and the other to decrease (-) a value.
