Using Ion library to load images from an expansion file

Question

I am using an expansion file to load additional resources and load images. My problem is that I can only use getInputStream and create a drawable from stream. Is that possible with Ion library?

Answer 1

You can implement your own loader by extending StreamLoader and have it load a expansion file URI of your choosing like expansion://myfile.jpg

See here for an example ContentLoader (which loads content streams).

And here's how to inject a loader into Ion's pipeline:
