Outdated binding?

Hi,

Thanks for sharing your work.

I try to use your project to create a binding of the navigation mapbox library (the nuget package seems old).
I use only the project
mapboxnavigation-droid
I use the 0.40.0 version (released in june 2019, at the same time of the last binding of your others project)

I fix an error in metadata.xml (a doinbackground with the wrong return type), and I build the nuget package. Then I include in my demo app, but the library throw an error because it cannot find Navigation (Java side).

Are the project still valid? Did I mess up the binding?
