    This is a client that can download & upload contact, calendar & task info from a syncing service like fruux to your Android device. Note that you cannot browse contacts in this app, you'll need another app for that, like Simple Contacts Pro. I think DAVx5 is a great choice for this in-between link, but it is not a one to one replacement for google contacts.

    Free and open source. Unfortunately it itself it's only a viable alternative to using Google Contacts from the web, but there are methods of syncing with your mobile devices, though I wish this were a far easier process.
