<p style="clear:left;">In some cases, the permissions that you request
through <code>&lt;uses-permission&gt;</code> can affect how
your application is filtered by Google Play.</p>

<p>If you request a hardware-related permission &mdash;
<code>CAMERA</code>, for example &mdash; Google Play assumes that your
application requires the underlying hardware feature and filters the application
from devices that do not offer it.</p>

<p>To control filtering, always explicitly declare
hardware features in <code>&lt;uses-feature&gt;</code> elements, rather than
relying on Google Play to "discover" the requirements in
<code>&lt;uses-permission&gt;</code> elements. Then, if you want to disable
filtering for a particular feature, you can add a
<code>android:required="false"</code> attribute to the
<code>&lt;uses-feature&gt;</code> declaration.</p>

<p>For a list of permissions that imply
hardware features, see the documentation for the <a
href="{@docRoot}guide/topics/manifest/uses-feature-element.html#permissions-features">
<code>&lt;uses-feature&gt;</code></a> element.</p>

<dd>Requests a permission that the application must be granted in
order for it to operate correctly.  Permissions are granted by the user when the
application is installed, not while it's running.

<p>
For more information on permissions, see the
<a href="{@docRoot}guide/topics/manifest/manifest-intro.html#perms">Permissions</a></code>
section in the introduction and the separate
<a href="{@docRoot}guide/topics/security/security.html">Security and Permissions</a> document.
A list of permissions defined by the base platform can be found at
{@link android.Manifest.permission android.Manifest.permission}.

<dd>The name of the permission.  It can be a permission defined by the
application with the <code><a href="{@docRoot}guide/topics/manifest/permission-element.html">&lt;permission&gt;</a></code>
element, a permission defined by another application, or one of the
standard system permissions, such as "{@code android.permission.CAMERA}"
or "{@code android.permission.READ_CONTACTS}".  As these examples show,
a permission name typically includes the package name as a prefix.</dd>
