I have a source code of an android file manager based application which uses to manage the data within the storages of the phone or device of android platform.
The screenshots are already attached for your better understanding.
You've to create a new Home Screen for the android File Manager application which will work as the screenshots shown in the attachment of this project.
As shown in the screenshots, that from Home SCreen user can access many different type of files and folders directly or he simply can go to any storage of the phone he wanted.
This Home SCreen will also show the remaining free space of that storage out of total available space as per attached screenshot and there will be a storage analyzer as well, which will tell the user that which file or folder he has not used since when.
User can also modify the list of these available functions to be shown on Home Screen (this section will be negotiable).
You only have to create a Home SCreen and put things as described, there is no hidden work, ok.
Also, you have to add the progress window as per attached screenshot, which will tell the user on the phone, about the progress of the selected data (files or folders) whether user is pasting the copied or cutted data or deleting the data or moving the data.
