I was just reading about this program on their website and notice that they recommend Calibre as the tool to get books converted into ePub so they can be moved onto an Android equipped device to read:
Aldiko.com\Support\GeneralWhat format does Aldiko support?
Aldiko supports the ePub format.
If you have non-DRMed books in the following formats: lit, pdf, mobi, rtf, txt, html, fb2, prc**, odt, cbr and cbz, you can use a free software called Calibre to convert any of the above formats to ePub and then import your books into Aldiko. You can get Calibre from here

Dr. Goyal, you're becoming famous!
