/**

 * Location access settings.

 * 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

 *         {@link android.provider.Settings.Secure#LOCATION_MODE} between

 *         {@link android.provider.Settings.Secure#LOCATION_MODE_OFF} and another location mode.

 *         </li>

 *         <li>Mode preference: only available if the master switch is on, selects between

 *         {@link android.provider.Settings.Secure#LOCATION_MODE} of

 *         {@link android.provider.Settings.Secure#LOCATION_MODE_HIGH_ACCURACY},

 *         {@link android.provider.Settings.Secure#LOCATION_MODE_BATTERY_SAVING}, or

 *         {@link android.provider.Settings.Secure#LOCATION_MODE_SENSORS_ONLY}.</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>

 * <p>

 * 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.
