Prerequisites -

1. You must have the JDK installed on your system.
2. Set the environment variables for the JDK.

Steps:

1. Open the command prompt.
2. Go to the ikvmc folder (ikvmc.exe comes with the ikvm package).
3. Enter the command ikvmc -out:myapp.dll myapp.jar

Is it possible that you forgot reference all needed IKVM .Net dlls?

IKVM.Runtime.dll IKVM.Reflection.dll IKVM.OpenJDK.*.dll

I've got something similar with SmsLib .Net version

First, create a new Bindings Library project. In Xamarin Studio or Visual Studio, create a new Solution and select the Android Bindings Library template.

The template includes a Jars folder where you add your .JAR(s) to the Bindings Library project. Right-click the Jars folder and select Add > Existing Item:

Navigate to the .jar file downloaded earlier, select it and click Add:

Verify that the .jar file was successfully added to the project:

right click your jar file=>properities =>choose embedded jar

Set the build action to EmbeddedJar:

EmbeddedJar – the .JAR will be embedded in the Bindings Library.

Set the target API level for your Bindings Library

Finally, build the Bindings Library. Although some warning messages may be displayed, the Bindings Library project should build successfully and produce an output .DLL at the following location:

Projectname/bin/Debug/JarBinding.dll
