The  Manifest Element
The content resolver object contains a set of methods that mirror those of the content provider (insert, query, delete etc.). The application simply makes calls to the methods, specifying the URI of the content on which the operation is to be performed. The content resolver and content provider objects then communicate to perform the requested task on behalf of the application.
== The The <provider> Manifest Element ==
In order for a content provider to be visible within an Android system, it must be declared within the Android manifest file for the application in which it resides. This is achieved using the <provider> element, which must contain the following items:
* '''android:authority authority''' – The full authority URI of the content provider. For example com.example.mydbapp.mydbapp.myprovider.
* '''android:name ''' – The name of the class that implements the content provider. In most cases, this will use the same value as the authority.
Similarly, the <provider> element may be used to define the permissions that must be held by client applications in order to qualify for access to the underlying data. If no permissions are declared, the default behavior is for permission to be allowed for all applications.
