Class Overview
Utility methods useful for working with Uri
objects
that use the "content" (content://) scheme.
Content URIs have the syntax
content://authority/path/id
-
content:
-
The scheme portion of the URI. This is always set to
ContentResolver.SCHEME_CONTENT
(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.
