<dd itemprop="description">Specifies which data subsets of the parent content provider permission
can be granted for.  Data subsets are indicated by the path part of a
{@code 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.

<p>
If a content provider's <code><a href="{@docRoot}guide/topics/manifest/provider-element.html#gprmns">grantUriPermissions</a></code>
attribute is "{@code true}", permission can be granted for any the data under
the provider's purview.  However, if that attribute is "{@code false}", permission
can be granted only to data subsets that are specified by this element.
A provider can contain any number of {@code &lt;grant-uri-permission&gt;} elements.
Each one can specify only one path (only one of the three possible attributes).
</p>

<p>
For information on how permission is granted, see the
<code><a href="{@docRoot}guide/topics/manifest/intent-filter-element.html">&lt;intent-filter&gt;</a></code> element's
<code><a href="{@docRoot}guide/topics/manifest/provider-element.html#gprmsn">grantUriPermissions</a></code> attribute.

<dd><dl class="attr">
<dt><a name="path"></a>{@code android:path}
<br/>{@code android:pathPrefix}
<br/>{@code android:pathPattern}</dt>
<dd>A path identifying the data subset or subsets that permission can be
granted for.  The {@code path} attribute specifies a complete path;
permission can be granted only to the particular data subset identified
by that path.
The {@code 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 {@code pathPattern} attribute specifies a complete path, but one
that can contain the following wildcards:

<ul>
<li>An asterisk ('{@code *}') matches a sequence of 0 to many occurrences of
the immediately preceding character.</li>

<li><p>A period followed by an asterisk ("{@code .*}") matches any sequence of
0 to many characters.</p></li>
</ul>

<p>
Because '{@code \}' is used as an escape character when the string is read
from XML (before it is parsed as a pattern), you will need to double-escape:
For example, a literal '{@code *}' would be written as "{@code \\*}" and a
literal '{@code \}' would be written as "{@code \\\\}".  This is basically
the same as what you would need to write if constructing the string in Java code.
</p>

<p>

{@link android.os.PatternMatcher#PATTERN_LITERAL},
{@link android.os.PatternMatcher#PATTERN_PREFIX}, and
{@link android.os.PatternMatcher#PATTERN_SIMPLE_GLOB} in the
{@link android.os.PatternMatcher} class.
