reading and writing on SD card

Postby RobotMan2412 » Sat Apr 14, 2018 7:19 am

Hi!
I would like to read from and write to the SD card.
I want to do this because i have made an OS for a robot arm and i would like to detect programs for it.
This would involve finding ALL the JAR files, loading them and searching them for a specific class with a specific superclass.
I need to get something like a file array or list from the program directory.
I potentially want to write here because of storing data for the OS.

Thanks in advance

PS: i might make building instructions for this robot arm soon.

So what have you actually tried so far? It's just a standard Linux file system you just use the standard Java file I/O operations. Oh and this is not really a development question, so I've moved it to the software section...
