public ArrayList<AppInfo> getInstallApps(Context context){
PackageManager pm = context.getPackageManager(); List<PackageInfo> installedPackages = pm.getInstalledPackages(0); //获取所以已安装的包
ArrayList<AppInfo> list = new ArrayList<AppInfo>(); for( PackageInfo packageInfo : installedPackages){
AppInfo info = new AppInfo();
String packageName = packageInfo.packageName; //包名
ApplicationInfo applicationInfo = packageInfo.applicationInfo; //应用信息
String name = applicationInfo.loadLabel(pm).toString(); //应用名称
Drawable icon = applicationInfo.loadIcon(pm); //应用图标
info.name = name;
info.packageName = packageName;
info.icon = icon; //状态机,通过01状态来表示是否具备某些属性和功能
int flags = applicationInfo.flags; //获取应用标记
