I need a script that will download all possible applications for Samsung phones and tablets from Google Play or directly from the Samsung servers. First I need to download all the apk and then the script should keep track for updates and download new versions. Also, the script should parse all the application information, including pictures, description and so on. On the output, I want to see on my server a directory with the application archive and files with pictures and information. Also I want to get advice on how to use Google accounts to work with the script.
