这个逻辑从服务器的.zip文件下载数据。这将获取的数据从您的域名服务器文件夹，并保存到PATH =/数据/数据​​/ your_pkg_name / app_my_sub_dir /图片/;
 //下载内容

This logic download a data from server as .Zip file. This will fetch data from your domain server folder and saved into the PATH=""/data/data/your_pkg_name/app_my_sub_dir/images/";
// Download Contents
