+  Requesting whitelist permissions
+</h3>
+
+<p>
+  If your app needs to use data in the background, it can request whitelist
+  permissions by sending a
+  <code>Settings.ACTION_IGNORE_BACKGROUND_DATA_RESTRICTIONS_SETTINGS</code>
+  (<code>"android.settings.IGNORE_BACKGROUND_DATA_RESTRICTIONS_SETTINGS"</code>)
+  intent with a <code>package:&lt;your-app-id&gt;</code> URI.
+</p>
+
+<p>
+  Sending the intent and URI launches the <strong>Settings</strong> app, and
+  displays your app's <strong>App Data Usage</strong> page to the user. The
+  user can then decide whether to enable background data for your app.
+  It is good practice to prompt the user before sending this intent.
