Public methods

notifyChildrenChanged

public void notifyChildrenChanged (MediaSession.ControllerInfo controller, 
                String parentId, 
                int itemCount, 
                MediaLibraryService.LibraryParams params)

Notify the controller of the change in a parent's children.

If the controller hasn't subscribed to the parent, the API will do nothing.

Controllers will use MediaBrowser.getChildren(String, int, int, LibraryParams) to get the list of children.

Parameters
`controller`	`MediaSession.ControllerInfo`: controller to notify
`parentId`	`String`: non-empty parent id with changes in its children
`itemCount`	`int`: number of children.
`params`	`MediaLibraryService.LibraryParams`: library params

notifyChildrenChanged

public void notifyChildrenChanged (String parentId, 
                int itemCount, 
                MediaLibraryService.LibraryParams params)

Notify all controllers that subscribed to the parent about change in the parent's children, regardless of the library params supplied by MediaBrowser.subscribe(String, LibraryParams).

Parameters
`parentId`	`String`: non-empty parent id
`itemCount`	`int`: number of children
`params`	`MediaLibraryService.LibraryParams`: library params

notifySearchResultChanged

public void notifySearchResultChanged (MediaSession.ControllerInfo controller, 
                String query, 
                int itemCount, 
                MediaLibraryService.LibraryParams params)

Notify controller about change in the search result.

Parameters
`controller`	`MediaSession.ControllerInfo`: controller to notify
`query`	`String`: previously sent non-empty search query from the controller.
`itemCount`	`int`: the number of items that have been found in the search.
`params`	`MediaLibraryService.LibraryParams`: library params
