Make IOnAssociationsChangedListener.onAssociationsChanged() blocking
Make IOnAssociationsChangedListener.onAssociationsChanged() blocking
(not "oneway") to make sure that the clients of the
addOnAssociationsChangedListener() API (@SystemAPI guarded by a
"signature" permission) are able to prevent race conditions that may
arise if their own clients (applications) effectively get notified
about the changes before system services do.
This is safe for 2 reasons:
1. The addOnAssociationsChangedListener() API is only available to the
system components (guarded by a "signature" permission).
See android.permission.MANAGE_COMPANION_DEVICES.
2. On the Java side addOnAssociationsChangedListener() in CDM takes an
Executor, and the proxy implementation of onAssociationsChanged()
simply "posts" a job to it.
See CompanionDeviceManager.OnAssociationsChangedListenerProxy class.
