Only one instance 25of the <code><compatible-screens></code> element is allowed in the manifest, but it can 26contain multiple <code><screen></code> elements. Each <code><screen></code> element 27specifies a specific screen size-density combination with which the application is compatible. 28 29 <p>The Android system <em>does not</em> read the {@code <compatible-screens>} manifest 30element (neither at install-time nor at runtime). This element is informational only and may be used 31by external services (such as Google Play) to better understand the application's compatibility 32with specific screen configurations and enable filtering for users. Any screen configuration that is 33<em>not</em> declared in this element is a screen with which the application is <em>not</em> 34compatible. Thus, external services (such as Google Play) should not provide the application to 35devices with such screens.</p> 36 37<p class="caution"><strong>Caution:</strong> Normally, <strong>you should not use this manifest 38element</strong>. Using this element can dramatically reduce the potential user base for your 39application, by not allowing users to install your application if they have a device with a screen 40configuration that you have not listed. You should use it only as a last resort, when the 41application absolutely does not work with specific screen configurations. Instead of using this 42element, you should follow the guide to <a href= 43"{@docRoot}guide/practices/screens_support.html">Supporting Multiple Screens</a> to 44provide scalable support for multiple screens using alternative layouts and bitmaps 45for different screen sizes and densities.</p> 46 47 <p>If you want to set only a minimum screen <em>size</em> for your your application, then you 48should use the <a href="{@docRoot}guide/topics/manifest/supports-screens-element.html">{@code 49<supports-screens>}</a> element. For example, if you want your application to be available 50only for <em>large</em> and <em>xlarge</em> screen devices, the <a 51href="{@docRoot}guide/topics/manifest/supports-screens-element.html">{@code 52<supports-screens>}</a> element allows you to declare that your application does not 53support <em>small</em> and <em>normal</em> screen sizes. External services (such as Google 54Play) will filter your application accordingly. You can also use the <a 55href="{@docRoot}guide/topics/manifest/supports-screens-element.html">{@code 56<supports-screens>}</a> element to declare whether the system should resize your 57application for different screen sizes.</p> 58 59 <p>Also see the <a href="{@docRoot}google/play/filters.html">Filters on Google Play</a> 60document for more information about how Google Play filters applications using this and 61other manifest elements.</p> 62 63</dd> 64 65<dt>child elements:</dt> 66<dd> 67 <dl class="tag-list"> 68 69 <dt id="screen">{@code <screen>}</dt> 70 <dd>Specifies a single screen configuration with which the application is compatible. 71 <p>At least one instance of this element must be placed inside the {@code 72<compatible-screens>} element.
