AGL Application Launcher service reference implementation

applaunchd is a simple service for launching applications from other applications. It exposes a gRPC RPC interface as described in the file protos/applauncher.proto.

The interface can be used to: - retrieve a list of available applications - request that a specific application be started by using the 'start' method - subcribe to a status signal (separate 'started' and/or 'terminated' signals for the D-Bus implementation) in order to be notified when an application has started successfully or terminated.

For more details about the deprecated D-Bus interface, please refer to the file data/org.automotivelinux.AppLaunch.xml.

Applications are enumerated from systemd's list of available units based on the pattern agl-app@.service, and are started and controled using their systemd unit. Please note applaunchd allows only one instance of a given application.

Note that while the gRPC and D-Bus implementations are comparable in functionality, they are not interoperable with respect to status notifications for applications started by the other interface. It is advised that their usage not be mixed in the same image to avoid confusion around application window activation.
