<dd>The highest API level at which this permission should be granted to your app.
Setting this attribute is useful if the permission your app requires is no longer needed beginning
at a certain API level.
<p>For example, beginning with Android 4.4 (API level 19), it's no longer necessary for your app
to request the {@link android.Manifest.permission#WRITE_EXTERNAL_STORAGE} permission when your
app wants to write to its own application-specific directories on external storage (the directories
provided by {@link android.content.Context#getExternalFilesDir getExternalFilesDir()}). However,
the permission <em>is required</em> for API level 18 and lower. So you can declare that this
permission is needed only up to API level 18 with a declaration such as this:
<pre>
&lt;uses-permission
android:name="android.permission.WRITE_EXTERNAL_STORAGE"
android:maxSdkVersion="18" />
</pre>
<p>This way, beginning with API level 19, the system will no longer grant your app the
{@link android.Manifest.permission#WRITE_EXTERNAL_STORAGE} permission.</p>
