Picasso data library Uri base64 schema

I need help implementing a data uri schema image decoder, I am getting a url with a string containing a base64 encoded image with something like this :: "Data: image / JPEG; base64, / 9J / 4AAQSkZJ ..... TY3OD == "

Is there an existing decoder or example on how to implement it in picasso?

I'm currently using a modified version of the Mapping Bitmaps Efficiently example, but the caching is really basic.

Thanks in Advance. Roberto.
