The Intent object is a common mechanism for starting new activity and transfering data from one activity to another. However, you cannot start a ContentProvider using an Intent.
When you want to access data in a ContentProvider, you must instead use the ContentResolver object in your application’s Context to communicate with the provider as a client. The ContentResolver object communicates with the provider object, an instance of a class that implements ContentProvider. The provider object receives data requests from clients, performs the requested action, and returns the results.
