The OverlayManagerListener connected to the OverlayManagerServiceImpl
should be notified when and only when the overlay settings have been
modified. The pattern used to fulfill this contract as a result of a
change to a target package is as follows:
if (updateAllOverlaysForTarget(...)) {
mListener.onOverlaysChanged(...);
}
Fix two violations of this pattern:
- The listener was always notified
- The listener was never notified
