Easiest way to access Google Contacts on Android

I need to basically create an Android app which accesses the contact information of a fixed Google account. If I'm not mistaken, it seems the GData API doesn't work on Android, while the Portable Contacts API doesn't suppo开发者_JAVA百科rt ClientLogin (which seems to be a lot simpler than OAuth). Do I have to use Portable Contacts + OAuth, or is there an easier way?
