android activesync equivalent for file syncing?

Greetings!

 

Making the move to android development from .NET CF (windows mobile/CE).

 

Going to try Xamarin (not rhomobile for now).

 

On windows mobile/CE we would use activesync to sync files containing collected data, or, build a desktop app to copy the files from the device using RAPI.

 

How does it work with Motorola android devices? Is there an activesync equivalent or would you build an app to detect & copy the data files from the device when the android device is connected i.e. like an external USB drive?

 

Thank you kindly,

Ben
