<provider>

Description

defines the path and access permissions for a subset of data within a Content Provider. This element can be defined more than once to specify multiple paths.

Property:

android:path

Content Provider The full URI path of a subset of the data. Only this part of the data indicated on this path will be authorized. If Content Provider is used to provide search suggestions, it must be followed by "/search_suggest_query".

android:pathPrefix

Content Provider The beginning of the URI path of the data subset. All data that is prefixed with this path can be authorized.

android:pathPattern

Content Provider the full URI path to the subset of data, except that you can use the following wildcard characters:

• asterisk (" * "). Matches 0 or more occurrences of the first character immediately following it.
• The period is followed by an asterisk (" .* "). Matches 0 or more occurrences of any character.

When reading a string from XML (before parsing as an expression), ' \ is used as an escape character and therefore requires two escapes: for example, ' * should be written ', ' ' \\* \ should be written ' \\\\ . This is basically the same as the syntax for constructing strings in Java code.

For more information about these three expressions, see the description of Pattern_literal, Pattern_prefix, and Pattern_simple_glob in the Patternmatcher class.

android:permission

the name of the permission that the client must have to read and write Content Provider data. This property provides a convenient way to set both read and write permissions. However, readPermission writePermission properties can override this setting.

android:readPermission

the permissions that the client must have to query the Content Provider data.

android:writePermission

the permissions that the client must have to modify the data that the Content Provider controls.
