/**
|
|
* The EmailServiceProxy class provides a simple interface for the UI to call into the various
|
|
* EmailService classes (e.g. ExchangeService for EAS). It wraps the service connect/disconnect
|
|
* process so that the caller need not be concerned with it.
|
|
*
|
|
* Use the class like this:
|
|
* new EmailServiceClass(context, class).loadAttachment(attachmentId, callback)
|
|
*
|
|
* Methods without a return value return immediately (i.e. are asynchronous); methods with a
|
|
* return value wait for a result from the Service (i.e. they should not be called from the UI
|
|
* thread) with a default timeout of 30 seconds (settable)
|
|
*
|
|
* An EmailServiceProxy object cannot be reused (trying to do so generates a RemoteException)
