therourke - you could run a basic http (web) server on your android phone and then use the browser on the Clara to access the epub/kepub/pdf files. An example http server is below:
https://play.google.com/store/apps/d...on.http.server
There are many others. I occasionally use the chrome extension:
https://chrome.google.com/webstore/d...jpcbhemlocgigb
to do the same from a chromebook.
