I want to create a folder programmatically for my application just like this screenshot.
To create a directory (aka, folder), call mkdirs() on the File object using the standard Java I / O file.
check attach screen shot This screenshot is for displaying a link to the icon folder.
You will need to contact the developers of this application and ask them what they use to identify the icon to apply to a specific directory. Directories on Android (and most other operating systems) do not have the icons themselves.
