This repository implements the BlinkID binding project for Xamarin.Forms and .NET MAUI. The binding provides C# wrappers for the BlinkID Android and iOS SDKs.

Updated Apr-23-2025 Drop support for Xamarin

Project Structure

• Omnicasa.Mobile.BlinkID.Droid - Xamarin Android binding for BlinkID Core
• Omnicasa.Mobile.BlinkID.iOS - Xamarin iOS binding for BlinkID
• Omnicasa.Mobile.BlinkID.Maui.Droid - .NET MAUI Android binding for BlinkID Core
• Omnicasa.Mobile.BlinkID.Maui.iOS - .NET MAUI iOS binding for BlinkID
• Omnicasa.Mobile.BlinkID.UX.Maui.Droid - .NET MAUI Android binding for BlinkID UX (currently uses Core only)
• Omnicasa.Mobile.BlinkID.Shared - Shared code for Xamarin projects
• Omnicasa.Mobile.BlinkID.Shared.Maui - Shared code for .NET MAUI projects

BlinkID Version

Current binding supports BlinkID SDK version 7.5.0.

Binding Notes

• Kotlin suspend functions (like initializeSdk) cannot be directly bound to C# due to Continuation parameter limitations
• The binding generates 115+ C# classes from the core BlinkID AAR

Use DI

container.Register<IBlinkIDService, BlinkIDService>();

private IBlinkIDService GetBlinkIDService()
{
 return StandardLocator?.Resolve<IBlinkIDService>();
}

Initialize

GetBlinkIDService()
 .Initialize("License")
 .Subscribe(success =>
 {
 System.Diagnostics.Debug.WriteLine($"Subscribe GetBlinkIDService: {success}");
 });

Scanning

BlinkIDService?
 .Scan()
 .Catch((Exception e) =>
 {
 System.Diagnostics.Debug.WriteLine(e.StackTrace);
 return Observable.Return<CardRecognizer>(null);
 })
 .Subscribe(card =>
 {
 System.Diagnostics.Debug.WriteLine(card.FirstName);
 });
