Java Binding Abstract class not being generated

Question

Error CS0234: The type or namespace name IBitmap\' does not exist in the namespaceCom.Sushi.Hangover\'. Are you missing an assembly reference?

Answer 1

In your binding library inside of the Transforms/Metadata.xml file you can change the visibility by adding the following line:

<attr path="/api/package[@name='com.sushi.hangover']/interface[@name='IBitmap']" name="visibility">public</attr>

Given that the package name in Java world is com.sushi.hangover and interface name is IBitmap.

You can read some more about the format of attr in the GAPI mono documentation. There is also some nice bindings documentation in the Xamarin Docs.

Answer 2

I've written a smallish guide on this topic that might help in certain areas: https://gist.github.com/JonDouglas/dda6d8ace7d071b0e8cb

In short, you could potentially try changing the visibility like @Cheesebaron has mentioned already: https://gist.github.com/JonDouglas/dda6d8ace7d071b0e8cb#class-visibility (Replace /class with interface or read the common paths)

Otherwise you can potentially try to add the node from scratch: https://gist.github.com/JonDouglas/dda6d8ace7d071b0e8cb#adding-types

For a more exact answer, I believe we would need to see the respective .jar/.aar and the current Bindings project.
