Finishing Unity and go back to Android

Hello.

I have exported Unity project to Eclipse and integrated it with my Android project. I can launch Unity project but I can not go back to my project. I have been reading about this on the Internet and have tried everything, but I do not get it.

Please, anyone know how to do it? I have a button in the Unity scene and I want to change to another activity when the user presses the button.

This is really urgent, please any help will be welcomed.

Thank you in advance.

 

Maybe this helpds... it's pretty easy to call a static java function from within Unity like this:

private AndroidJavaClass javaclass = new AndroidJavaClass("com.company.product.CustomActivity");
javaclass.CallStatic("switchActivity");

I had little luck calling non-static functions though...

 

Thank you Trilusion, but I think we can not use that, because we don't have any Android plugin, we exported the Unity project as an Eclipse project and included it in other Android project. (May be I am wrong but I think that if you use AndroidJavaClass.CallStatic method you need to have that class inside your Unity project).

Thank you anyway!
