contained in:
Specifies the subsets of app data that the parent content provider has permission to access. Data subsets are indicated by the path part of a content: URI. The authority part of the URI identifies the content provider. Granting permission is a way of enabling clients of the provider that don't normally have permission to access its data to overcome that restriction on a one-time basis.

If a content provider's grantUriPermissions attribute is true, permission can be granted for any of the data under the provider's purview. However, if that attribute is false, permission is granted only to data subsets that are specified by this element. A provider can contain any number of <grant-uri-permission> elements. Each one can specify only one path, using one of the three possible attributes.

For information about how permission is granted, see the <intent-filter> element's grantUriPermissions attribute.

A path identifying the data subset or subsets that permission can be granted for. The path attribute specifies a complete path. Permission can granted only to the particular data subset identified by that path.

The pathPrefix attribute specifies the initial part of a path. Permission can be granted to all data subsets with paths that share that initial part. The pathPattern attribute specifies a complete path, but one that can contain the following wildcards:

  • An asterisk (*) matches a sequence of zero to many occurrences of the immediately preceding character.
  • A period followed by an asterisk (.*) matches any sequence of zero to many characters.

Because \ is used as an escape character when the string is read from XML, before it is parsed as a pattern, you need to double-escape. For example, a literal * is written as \\* and a literal \ is written as \\\.

For more information about these types of patterns, see the descriptions of PATTERN_LITERAL, PATTERN_PREFIX, and PATTERN_SIMPLE_GLOB in the PatternMatcher class.
