【实现逻辑】 通过在property_service.c中设置标志位，在设置中实现接口改变标志位， 使用init.rc中声明的服务来侦听标志位的变化，显式启动声明的服务，执行对应的脚本，把应用后缀从apk重命名为bak，从而实现隐藏（显示逻辑相反）。
【实现步骤】以隐藏Google Play Store（system/priv-app/Phonesky.apk）为例： 1.首先在system/core/init/property_service.c中声明并初始化标志位，0为隐藏，1为显示，默认隐藏

{ app.launcher.start, AID_SYSTEM, 0},+ { app.phonesky.show, AID_SYSTEM, 0}, //Add By zj { cdma., AID_RADIO, 0 }, //Add by gfzhu VIA |
2.在设置的开发者选项中实现对应的接口： 文件路径：packages/apps/Settings/src/com/android/settings/DevelopmentSettings.java ①声明和初始化：

private static final String SHOW_PHONESKY = show_phonesky;private CheckBoxPreference mShowPhonesky;mShowPhonesky = findAndInitCheckboxPref(SHOW_PHONESKY); |
②CheckBox的逻辑：

(BatteryManager.BATTERY_PLUGGED_AC | BatteryManager.BATTERY_PLUGGED_USB) : 0);+ } else if (preference == mShowPhonesky) { // ZJ Add+ if(mShowPhonesky.isChecked())+ {+ SystemProperties.set(app.phonesky.show,1);+ }else{+ SystemProperties.set(app.phonesky.show,0);+ } } else if (preference == mBtHciSnoopLog) { |
③增加一个Preference： packages/apps/Settings/res/xml/development_prefs.xml
