# Import Java SDK in C

### Overview

We have transformed the SDK, originally an Android Archive (AAR) file, into a Dynamic Link Library (DLL) file. This allows C# programs to utilize the SDK. You can download [the demo](http://ftp.wizarpos.com/device/UseAARdemo_20231106.zip) from the provided link.

### Key Points

* Current Demo Version: The demo uses a DLL converted from the AAR package of version 1.5.4.82.
* Version Updates: If there's a need to update to a newer version during development, please contact WizarPOS support for assistance.

### Additional Information

* Binding an AAR in Xamarin: For guidance on how to bind an .AAR file in Xamarin, refer to the Microsoft documentation available at [Binding an AAR](https://learn.microsoft.com/en-us/xamarin/android/platform/binding-java-library/binding-an-aar).
