+<p><strong>Caution:</strong> Over time,
+new restrictions may be added to the platform such that, in order
+to use certain APIs, your app must request a permission that it previously did not need.
+Because existing apps assume access to those APIs is freely available,
+Android may apply the new permission request to the app's manifest to avoid
+breaking the app on the new platform version.
+Android makes the decision as to whether an app might need the permission based on
+the value provided for the <a
+href="{@docRoot}guide/topics/manifest/uses-sdk-element.html#target">{@code targetSdkVersion}</a>
+attribute. If the value is lower than the version in which the permission was added, then
+Android adds the permission.</p>
+<p>For example, the {@link android.Manifest.permission#WRITE_EXTERNAL_STORAGE} permission was
+added in API level 4 to restrict access to the shared storage space. If your <a
+href="{@docRoot}guide/topics/manifest/uses-sdk-element.html#target">{@code targetSdkVersion}</a>
+is 3 or lower, this permission is added to your app on newer versions of Android.</p>
+<p>Beware that if this happens to your app, your app listing on Google Play will show these
+required permissions even though your app might not actually require them.</p>
+<p>To avoid this and remove the default permissions you don't need, always update your <a
+href="{@docRoot}guide/topics/manifest/uses-sdk-element.html#target">{@code targetSdkVersion}</a>
+to be as high as possible. You can see which permissions were added with each release in the
+{@link android.os.Build.VERSION_CODES} documentation.</p>
