* Renamed ISyncManager/ISyncManagerCallback to IEmailService/IEmailServiceCallback
* Restored ExchangeTransportExample to its original state; created ExchangeStore to
handle validation functionality instead; updated stores.xml to reflect these changes.
* Add support for AccountManager in EAS code (this is necessary for the contacts and
calendar providers to work with syncable data); created EasAuthenticatorService to
as our authenticator, which required adding authenticator.xml and modifying the
manifest to register our service with AccountManager metadata
* Created EmailServiceProxy as a convenience for the UI in calling into the EAS
service; created EmailServiceStatus class for status codes in callbacks.
* There is some temporary code ensuring that SyncManager runs (this will be removed when Exchange
is entirely independent)
* The service interface (aidl) is in place for most user-facing actions (load more, start sync, etc.)
* EAS account validation is done via aidl
* Folder and message sync appear to be functional in this early submission
* Provider now does cascading deletes (Account -> HostAuth and Mailbox, Mailbox -> Message,
Message -> Attachment and Body)
the shipping client will include the necessary generic pieces for
configuring an Exchange client (e.g. account setup) but will not
include actual Exchange client code (e.g. transport / protocol).
Also added a "sample code" implementation of Exchange for use
as a starting point for implementors. (Note, this will not ship
in Donut, it's a placeholder for working on the "framework"
aspects.)
