If XWalkClient is not provided, by default XWalkView will ask Activity Manager to choose the proper handler for the url. If XWalkClient is provided, return true means the host application handles the url, while return false means the current XWalkView handles the url.

Parameters:

view - The XWalkView that is initiating the callback.

url - The url to be loaded.

Returns:

True if the host application wants to leave the current XWalkView and handle the url itself, otherwise return false.
