Utility methods useful for working with Android.Net.Uri objects that use the "content" (content://) scheme.

content:

The scheme portion of the URI. This is always set to ContentResolver.SchemeContent (value content://).

authority

A string that identifies the entire content provider. All the content URIs for the provider start with this string. To guarantee a unique authority, providers should consider using an authority that is the same as the provider class' package identifier.

path

Zero or more segments, separated by a forward slash (/), that identify some subset of the provider's data. Most providers use the path part to identify individual tables. Individual segments in the path are often called "directories" although they do not refer to file directories. The right-most segment in a path is often called a "twig"

id

A unique numeric identifier for a single row in the subset of data identified by the preceding path part. Most providers recognize content URIs that contain an id part and give them special handling. A table that contains a column named _ID often expects the id part to be a particular value for that column.

Content URIs have the syntax

content://authority/path/id
