Android - Search for a filename then download in a web (http) folder

I am trying to make my Android app connect to a URL on the web, retrieve a list of the files, search for one file that includes a custom String in its name, and download it.

The name of the file is in the following format:

"StoresFull000000000-0000-000000000"

The "StoresFull" is the name I will be searching on all the files in the folder and the '0' are numbers that will be different in every folder.

Thanks
