Connecting to Kindle Android App in a Nexus 7

Hello. This is my first post here.

I recently installed Calibre on my PC. I am not sure if it already supports connection to Kindle Android app on a Nexus 7 tablet.

Is that possible, by cable or by air? I mean, I know I could do some tweaks (for example, as my Calibre library folder is in my Dropbox folder, I can access it at my Nexus 7 tablet through Dropbox Android app), but I thought it could be done by "click and drag" in Calibre, as it is shown in the video tutorial.

Please, could you help me? If my request is not clear enough, please tell me.

Looking forward to your answer,
