     * Broadcast intent action for Settings app to inject a footer at the bottom of location

     * settings.

     *

     * <p>This broadcast is used for two things:

     * <ol>

     *     <li>For receivers to inject a footer with provided text. This is for use only by apps

     *         that are included in the system image. </li>

     *     <li>For receivers to know their footer is injected under location settings.</li>

     * </ol>

     *

     * <p>To inject a footer to location settings, you must declare a broadcast receiver of

     * {@link LocationManager#SETTINGS_FOOTER_DISPLAYED_ACTION} in the manifest as so:

     * <pre>

     *     <receiver android:name="com.example.android.footer.MyFooterInjector">

     *         <intent-filter>

     *             <action android:name="com.android.settings.location.INJECT_FOOTER" />

     *         </intent-filter>

     *         <meta-data

     *             android:name="com.android.settings.location.FOOTER_STRING"

     *             android:resource="@string/my_injected_footer_string" />

     *     </receiver>

     * </pre>

     *

     * <p>On entering location settings, Settings app will send a

     * {@link #SETTINGS_FOOTER_DISPLAYED_ACTION} broadcast to receivers whose footer is successfully

     * injected. On leaving location settings, the footer becomes not visible to users. Settings app

     * will send a {@link #SETTINGS_FOOTER_REMOVED_ACTION} broadcast to those receivers.

     *
