Public methods

onChildrenChanged

public void onChildrenChanged (MediaBrowser browser, 
                String parentId, 
                int itemCount, 
                MediaLibraryService.LibraryParams params)

Called when there's change in the parent's children after you've subscribed to the parent with MediaBrowser.subscribe(String, MediaLibraryService.LibraryParams).

This API is called when the library service called MediaLibraryService.MediaLibrarySession.notifyChildrenChanged(MediaSession.ControllerInfo, String, int, MediaLibraryService.LibraryParams) for the parent.

Parameters
`browser`	`MediaBrowser`: the browser for this event
`parentId`	`String`: non-empty parent id that you've specified with `MediaBrowser.subscribe(String, LibraryParams)`
`itemCount`	`int`: number of children
`params`	`MediaLibraryService.LibraryParams`: library params from the library service. Can be differ from params that you've specified with `MediaBrowser.subscribe(String, LibraryParams)`.

onSearchResultChanged

public void onSearchResultChanged (MediaBrowser browser, 
                String query, 
                int itemCount, 
                MediaLibraryService.LibraryParams params)

Called when there's change in the search result requested by the previous MediaBrowser.search(String, LibraryParams).

Parameters
`browser`	`MediaBrowser`: the browser for this event
`query`	`String`: non-empty search query that you've specified with `MediaBrowser.search(String, LibraryParams)`
`itemCount`	`int`: The item count for the search result
`params`	`MediaLibraryService.LibraryParams`: library params from the library service. Can be differ from params that you've specified with `MediaBrowser.search(String, LibraryParams)`.
