/**
|
|
* Note that there are two ways the EAS ExchangeService service can be created:
|
|
*
|
|
* 1) as a background service instantiated via startService (which happens on boot, when the
|
|
* first EAS account is created, etc), in which case the service thread is spun up, mailboxes
|
|
* sync, etc. and
|
|
* 2) to execute an RPC call from the UI, in which case the background service will already be
|
|
* running most of the time (unless we're creating a first EAS account)
|
|
*
|
|
* If the running background service detects that there are no EAS accounts (on boot, if none
|
|
* were created, or afterward if the last remaining EAS account is deleted), it will call
|
|
* stopSelf() to terminate operation.
|
|
*
|
|
* The goal is to ensure that the background service is running at all times when there is at
|
|
* least one EAS account in existence
|
|
*
|
|
* Because there are edge cases in which our process can crash (typically, this has been seen
|
|
* in UI crashes, ANR's, etc.), it's possible for the UI to start up again without the
|
|
* background service having been started. We explicitly try to start the service in Welcome
|
|
* (to handle the case of the app having been reloaded). We also start the service on any
|
|
* startSync call (if it isn't already running)
