- uri
- The URI to watch for changes. This can be a specific row URI, or a base URI for a whole class of content.
- notifyForDescendents
- If true changes to URIs beginning with uri will also cause notifications to be sent. If false only changes to the exact URI specified by uri will cause notifications to be sent. If true, any URI values at or below the specified URI will also trigger a match.
- observer
- The object that receives callbacks when changes occur.
Register an observer class that gets callbacks when data identified by a given content URI changes.
