Upload to Google Books works fine for me. I tested a few send to app that worked fine - Dropbox and K-9 mail worked. Send to app had gReader came up in the list and tried to add a subscription which obviously did not work. Send to app for ES File Explorer send by LAN did not work as expected. I have it set up to my pc by LAN and sent a book manually, but using CC I got the error in the screen shot.
