Xamarin Forms

ErrLog.IO and Xamarin.Forms

Xamarin.Forms is a .Net framework used for building cross-platform applications for iOS, Android and Windows (UWP). ErrLog is fully supported in Xamarin.Forms, and is a great way to take more control over your exception loggins when developing cross-platform applications.

These examples assume you have a typical Shared Project containing your shared class library and platform-specific sub-projects.

Use Nuget or an equivalent package manager to download and install ErrLog.IO. Remember to install the package for each platform-specific project - iOS, Android and UWP.

Package Manager
.NET CLI

Install-Package errlog.io

dotnet add package errlog.io

Typically you can activate ErrLog.IO either on a page-by-page basis, or within your startup class.

public partial class MainPage : ContentPage
{ 
	public MainPage ()
	{
		ErrLog.settings.apikey = "[Your-api-key]";
	}
}

Global App Startup Class

You can also install ErrLog.IO in your app.xaml.cs class.

public partial class App : Application
{
	public App()
	{
		InitializeComponent();

		ErrLog.settings.apikey = "[Your-api-key]";
	}
}

There are a number of event handlers available in Xamarin.Forms for capturing exceptions. Below are examples of how to add a custom event handler to send Exceptions directly to ErrLog.IO

Shared Class Library

static void logError(object sender, UnhandledExceptionEventArgs args)
{
	Exception ex = (Exception)args.ExceptionObject;
	ErrLog.logger.log(ex);
}

Android

AppDomain.CurrentDomain.UnhandledException += logError;
TaskScheduler.UnobservedTaskException += logError;
AndroidEnvironment.UnhandledExceptionRaiser += logError;

iOS

AppDomain.CurrentDomain.UnhandledException += async (sender, e) => logError
TaskScheduler.UnobservedTaskException += async (sender, e) => logError

Windows UWP

UnhandledException += logError;
