我是靠谱客的博主无限小猫咪，这篇文章主要介绍android 获取已安装应用(App)列表，现在分享给大家，希望可以做个参考。

效果图

获取手机上已安装应用列表，将获取到的信息用集合返回，可以自己定义是否过滤系统应用，Appinfo是一个实体类，包含应用的名称包名图标icon等等

复制代码

/**
     * 获取手机已安装应用列表
     * @param ctx
     * @param isFilterSystem 是否过滤系统应用
     * @return
     */
    public static ArrayList<AppInfo> getAllAppInfo(Context ctx,boolean isFilterSystem) {
        ArrayList<AppInfo> appBeanList = new ArrayList<>();
        AppInfo bean = null;

PackageManager packageManager = ctx.getPackageManager();
        List<PackageInfo> list = packageManager.getInstalledPackages(0);
        for (PackageInfo p : list) {
            bean = new AppInfo();
            bean.setIcon(p.applicationInfo.loadIcon(packageManager));
            bean.setLabel(packageManager.getApplicationLabel(p.applicationInfo).toString());
            bean.setPackage_name(p.applicationInfo.packageName);
            int flags = p.applicationInfo.flags;
            // 判断是否是属于系统的apk
            if ((flags & ApplicationInfo.FLAG_SYSTEM) != 0&&isFilterSystem) {
//                bean.setSystem(true);
            } else {
                appBeanList.add(bean);
            }
        }
        return appBeanList;
    }
