代码路径:
packages/apps/Settingssrc/com/android/settings/core/gateway/SettingsGateway.java
packages/apps/Settingsres/xml/top_level_settings.xml
1、在/top_level_settings.xml布局文件中去掉已连接的设备选项
<Preference android:key="top_level_apps_and_notifs" android:title="@string/app_and_notification_dashboard_title" android:summary="@string/app_and_notification_dashboard_summary" android:icon="@drawable/ic_homepage_apps" android:order="-100" android:fragment="com.android.settings.applications.AppAndNotificationDashboardFragment"/>
2、在SettingsGateway.java文件中SETTINGS_FOR_RESTRICTED数组中屏蔽掉AppAndNotificationDashboardActivity
public static final String[] SETTINGS_FOR_RESTRICTED = { Settings.AppAndNotificationDashboardActivity.class.getName() }
