Method Details

decidePolicy

public UnbluExternalLinkHandlingPolicy decidePolicy(android.net.Uri url)

Determines the handling policy for a given URL within a conversation. This method checks the URL against a list of predefined URL patterns. If the URL matches any of the patterns, it permits opening the link by returning UnbluExternalLinkHandlingPolicy.OPEN. If the URL does not match any pattern, the link is not allowed to be opened, indicated by returning UnbluExternalLinkHandlingPolicy.BLOCK. This approach allows for fine-grained control over which links can be opened, enhancing security by preventing potentially harmful links from being accessed.

Specified by:

decidePolicy in interface UnbluExternalLinkHandler

Parameters:

url - The Uri object representing the link that was clicked. This parameter is used to extract the string representation of the URL for pattern matching.

Returns:

The UnbluExternalLinkHandlingPolicy indicating whether the link should be opened or blocked. If the URL matches a predefined pattern, UnbluExternalLinkHandlingPolicy.OPEN is returned, otherwise UnbluExternalLinkHandlingPolicy.BLOCK is returned.
