Android Jar file inside a Jar file

[Tripwire]

Hi,

I’m trying to create a plugin from an existing Jar file called IndoorAtlas. When I write my custom code (UnityBridge.java) I have to export the whole package to a jar file to get it to work in Unity3D. So the follwing happends:
IndoorAtlas.jar is contained in the newly exported jar file from eclipse.

When calling functions to test out if the connection between my UnityBridge.java and Unity3D it all works fine. But when I try to call functions in the IndoorAtlas.jar file, I get the following error:

07-21 17:22:55.808: I/Unity(21411): AndroidJavaException: java.lang.NoSuchMethodError: no method with name=‘GetInt’ signature=‘()I’ in class Lcom/indooratlas/example/UnityBridge;

EDIT:
To make it clearer the code has to do the following:
Unity3D C# → UnityBridge.Java → IndoorAtlas.jar
IndoorAtlas.jar ->UnityBridge.Java → Unity3D C#

Is there a way to get this working?

Hi Mr tripwire, i know that it has been a long time since you posted this thread, but I’m interested in knowing if you were able to make the plugin work in unity. I’m also working on a unity project that features indoor positioning, and i’m trying to implement Indoor Atlas in it. The problem is that i have a little knowledge about how to do it. So i would appreciate it if you can give me some informations that could help me to solve the problem.
Thanks for your time
