Disabling the shortcut if no service is configured, so we users won't see an "On" unless the shortcut will have an effect. If no service is configured and the user tries to enable the shortcut, the service picking UI is shown. If the user chooses a service, the shortcut turns on. If not, the shortcut remains off. Service selection is disabled when the shortcut is disabled (except for the specific case above). Lock screen behavior selection is disabled when the shortcut is disabled. Also updating a couple of strings based on UX input. Adding an AOSP header to a file that somehow got checked in without one. Fixes: 37443184 Fixes: 38030853 Test: Manually went through the various combinations of shortcut on and service enabled. I turned off the default selection of TalkBack as the shortcut service to ensure that we show a dialog when no service is selected. Change-Id: Iac5cff12edea91a496fc81781518db4ae49ef334
