Need to update an open source ftp app. You need to check if all the functionality are working nicely and then put a directory to list all the files as the "local" file. By using this directory user can choose directory from his mobile phone, connected device(usb connected) and from Google Drive.
You need to make the total app design very cute n professional.
Please write: "I m here" at the top of your application so that I can understand that you have read the the requirement.
