<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>
