Kindle App on Phone and Calibre

Hi,

I am wondering if it is at all possible to transfer the kindle books I have downloaded using the Kindle app for android on my phone into calibre?

When I connect my phone it comes up with Device and Card A but when I click on them they are both blank?

I have put the following into the config for both of them:

eBooks/import, wordplayer/calibretransfer, Books

Still no luck. Is it possible to see my kindle books on my phone using calibre and then transfer them?
