First create a new Bindings library project. In Xamarin Studio or Visual Studio, create a new solution and select the Bindings library template for Android.
The template includes the Jars folder into which you add the .JAR to the Bindings Library project. Right-click the Jars folder and choose Add> Existing Element:
Browse to the .jar file you downloaded earlier, select it and click Add:
Verify that the .jar file has been successfully added to the project:
right click your file jar => properities => select the built-in jar
Set the build action for EmbeddedJar:
EmbeddedJar -.JAR will be embedded in the Bindings library.
Set API target level for your Bindings library
Finally, create the Bindings library. Although some warning messages may be displayed, the Bindings library project should succeed and generate the output .DLL in the following location:
Projectname / bin / Debug / JarBinding.dll
