  <dd>An integer designating the maximum API Level on which the application is 

  designed to run. 



  <p>In Android 1.5, 1.6, 2.0, and 2.0.1, the system checks the value of this

  attribute when installing an application and when revalidating the application

  after a system update. In either case, if the application's

  <code>android:maxSdkVersion</code> attribute is lower than the API Level used by

  the system itself, then the system will not allow the application to be

  installed. In the case of revalidation after system update, this effectively

  removes your application from the device.



  <p>To illustrate how this attribute can affect your application after system

  updates, consider the following example: </p>



  <p>An application declaring <code>android:maxSdkVersion="5"</code> in its

  manifest is published on Android Market. A user whose device is running Android

  1.6 (API Level 4) downloads and installs the app. After a few weeks, the user

  receives an over-the-air system update to Android 2.0 (API Level 5). After the

  update is installed, the system checks the application's

  <code>android:maxSdkVersion</code> and successfully revalidates it. The

  application functions as normal. However, some time later, the device receives

  another system update, this time to Android 2.0.1 (API Level 6). After the

  update, the system can no longer revalidate the application because the system's

  own API Level (6) is now higher than the maximum supported by the application

  (5). The system prevents the application from being visible to the user, in

  effect removing it from the device.</p>



  <p class="warning"><strong>Warning:</strong> Declaring this attribute is not

  recommended. First, there is no need to set the attribute as means of blocking

  deployment of your application onto new versions of the Android platform as they

  are released. By design, new versions of the platform are fully

  backward-compatible. Your application should work properly on new versions,

  provided it uses only standard APIs and follows development best practices.

  Second, note that in some cases, declaring the attribute can <strong>result in

  your application being removed from users' devices after a system

  update</strong> to a higher API Level. Most devices on which your appplication

  is likely to be installed will receive periodic system updates over the air, so

  you should consider their effect on your application before setting this

  attribute.</p>



  <p style="margin-bottom:1em;">Introduced in: API Level 4</p>



  <div class="special">Future versions of Android (beyond Android 2.0.1) will no

longer check or enforce the <code>android:maxSdkVersion</code> attribute during

installation or revalidation. Android Market will continue to use the attribute

as a filter, however, when presenting users with applications available for

download. </div>
