I'm sorry, I should have also mentioned our Direct Mode feature! Any Eye-Fi X2 card can wirelessly transfer photos directly to a compatible device running our software with no wi-fi network needed - this would be any compatible Windows/Mac computer with wi-fi, or an iOS or Android device.http://www.eye.fi/how-it-works/features/direct-modehttp://support.eye.fi/features/direct/
To send from Android to a computer using Eye-Fi, both devices would need an internet connection. If you want a solution that doesn't require wi-fi, you could connect the Android device via a USB cable.
Please feel free to add your voice to our Feature Requests forum if you'd like to request an option for us to transfer photos automatically via USB. Some users refer to this as "Impatient mode" and have discussed it in other threads, like viewtopic.php?f=10&t=1803&p=18679
