<p><em>A note about camera:</em> If an

        application requests the CAMERA permission using the <a

href="{@docRoot}guide/topics/manifest/uses-permission-element.html"> <code>&lt;uses-permission&gt;</code></a> element, Market assumes that the

        application requires the camera and all camera features (such as autofocus). For applications that require the camera and are designed to run on Android 1.5 (API Level 3), declaring the CAMERA permission is an effective way of ensuring that Market filters your app properly, since <code>uses-feature</code> filtering is not available to applications compiled against the Android 1.5 platform. For more details about requiring or requesting a camera, see the <a href="{@docRoot}guide/topics/manifest/uses-library-element.html#required"> <code>required</code></a> attribute of <code>&lt;uses-feature&gt;</code>. </p></td>

    <td valign="top">Strictly, Android Market does not filter based on

<code>&lt;uses-permission&gt;</code> elements. However, it does read the

elements to determine whether the application has hardware feature requirements

that may not have been properly declared in <code>&lt;uses-feature&gt;</code>

elements. For example, if an application requests the <code>CAMERA</code>

permission but does not declare a <code>&lt;uses-feature&gt;</code> element for

<code>android.hardware.camera</code>, Android Market considers that the

application requires a camera and should not be shown to users whose devices do

not offer a camera.</p>

    <p>In general, if an application requests hardware-related permissions,

Android Market assumes that the application requires the underlying hardware

features, even though there might be no corresponding to

<code>&lt;uses-feature&gt;</code> declarations. Android Market then sets up

filtering based on the features implied by the <code>&lt;uses-feature&gt;</code>

declarations.</p>

hardware features in <code>&lt;uses-feature&gt;</code> elements, rather than

relying on Android Market to "discover" the requirements in

filtering for a particular feature, you can add a
