Hi Dmitri,
So, if I want to sync with my own backend which supports a different
protocol, my assumption is that I need to somehow "register" a Sync
Adapter, in which case, I'll have my own SyncAdapterType. I can't
seem to find documentation on this, and the only thing I can find is a
class called AbstractThreadedSyncAdapter. I'm assuming there must be
a service I must implement involved somewhere, but I can't seem to
find anything. Would you be able to point me in the right direction?
Thanks,
Jonathan Herriott
