Android 8.1 隐藏设置中定位功能

最近接到客户反馈，需要隐藏设备设置中的定位功能，具体修改参照如下：
/vendor/mediatek/proprietary/packages/apps/MtkSettings/src/com/android/settings/SecuritySettings.java

        mLocationcontroller.displayPreference(root);mManageDeviceAdminPreferenceController.updateState(root.findPreference(KEY_MANAGE_DEVICE_ADMIN));mEnterprisePrivacyPreferenceController.displayPreference(root);mEnterprisePrivacyPreferenceController.onResume();/// M: Add plugin itemsPreferenceGroup deviceAdminCategory = (PreferenceGroup) root.findPreference(KEY_DEVICE_ADMIN_CATEGORY);addPluginEntrance(deviceAdminCategory);
+        root.findPreference(KEY_LOCATION).setVisible(false);return root;

到这里，在设置的搜索框中输入定位关键字仍能搜索到相关功能选项，想要屏蔽掉的话具体修改参照如下：

/vendor/mediatek/proprietary/packages/apps/MtkSettings/src/com/android/settings/search/SearchIndexableResources.java

        addIndex(LanguageAndInputSettings.class, NO_DATA_RES_ID, R.drawable.ic_settings_language);
-        addIndex(LocationSettings.class, R.xml.location_settings, R.drawable.ic_settings_location);
-        addIndex(ScanningSettings.class, R.xml.location_scanning, R.drawable.ic_settings_location);addIndex(SecuritySettings.class, NO_DATA_RES_ID, R.drawable.ic_settings_security);addIndex(EncryptionAndCredential.class, NO_DATA_RES_ID, R.drawable.ic_settings_security);

重新编译验证，修改生效，设置中的定位功能已屏蔽
