【BUG】【K631AN】【应用分身】下载支持应用分身的应用（QQ），开启应用分身，返回桌面，会出现所有应用的分身。

1、进入设置中的应用界面逻辑代码

AppDashboardFragment.java,通过getPreferenceScreenResId()进入应用界面的布局文件app.xml

user()方法，是父类DashboardFragment的方法

 protected <T extends AbstractPreferenceController> T use(Class<T> clazz) {List<AbstractPreferenceController> controllerList = mPreferenceControllers.get(clazz);if (controllerList != null) {if (controllerList.size() > 1) {Log.w(TAG, "Multiple controllers of Class " + clazz.getSimpleName()+ " found, returning first one.");}return (T) controllerList.get(0);}return null;}

3、计算应用界面中应用的数量

通过该界面的布局文件app.xml中的key-> recent_apps_category

进入AppsPreferenceController.java类中，该类计算当前应用的数量，并且显示当前使用的应用数量

通过分析，可知，该方法中的loadAllAppsCount()加载所有app的数量，该方法实例化InstalledAppCounter类，并重写onCountComplete()方法

进入超父类AppCounter.java中

doInBackground方法进行计算总数量，该计算方法，通过遍历用户和应用双重遍历进行计算，所以算出来的数量double，所以在doInBackground(Void... params)中，只获取第一个用户，在进行遍历应用

该界面的方法ManageApplications.java类来显示应用图标和名字

该类有两个内部类适配器

FilterSpinnerAdapter-> SettingsSpinnerAdapter的适配器

ApplicationsAdapter-> RecyclerView的适配器
