988574 - Implement and use AsyncTaskLoader for retrieving Firefox Accounts and internal account State

Status: RESOLVED INCOMPLETE

(Firefox for Android Graveyard :: Firefox Accounts, defect, P5)

Description

[Nick Alexander :nalexander [he/him]]

We've been playing a little fast and loose with our FxAccount activities.  We query -- synchronously -- for any existing FxAccounts in onResume.  This is slow, blocks the main thread, spams the log with strict mode warnings, and is not correct in the face of account status changes.

We can address this by implementing an AsyncTaskLoader that does this work in the background and (optionally) notifies its consumers when the underlying Account State has changed.  This should provide a good unification of this Account loading code.
