/**
* System location settings (Settings > Location). The screen has three parts:
* <ul>
* <li>Platform location controls</li>
* <ul>
* <li>In switch bar: location master switch. Used to toggle location on and off.
* </li>
* </ul>
* <li>Recent location requests: automatically populated by {@link RecentLocationApps}</li>
* <li>Location services: multi-app settings provided from outside the Android framework. Each
* is injected by a system-partition app via the {@link SettingInjectorService} API.</li>
* </ul>

* Note that as of KitKat, the {@link SettingInjectorService} is the preferred method for OEMs to
* add their own settings to this page, rather than directly modifying the framework code. Among
* other things, this simplifies integration with future changes to the default (AOSP)
* implementation.
