     * Constant to return from {@link android.app.Service#onStartCommand}: if this
     * service's process is killed while it is started (after returning from
     * {@link android.app.Service#onStartCommand}), then leave it in the started
     * state but don't retain this delivered intent.  Later the system will try to
     * re-create the service.  Because it is in the started state, it will
     * guarantee to call {@link android.app.Service#onStartCommand} after creating
     * the new service instance; if there are not any pending start commands to be
     * delivered to the service, it will be called with a null intent
     * object, so you must take care to check for this.
     *
     * This mode makes sense for things that will be explicitly started
     * and stopped to run for arbitrary periods of time, such as a service
     * performing background music playback.
