Hi, I have a problem. I was creating an app and I put that if you longclick on a button, it will create that file (sound) to your sdcard folder. The problem is : when you longclick on the button, it will always download the file, how to check if that file already exists?
The program should be like :
Check sdcard folder, if that file exists, then Notifier says "This file already exists", else, if it doesn't exist in that folder, it will create the file.
Can you help me in doing this please? It would be better if you could post some screens. Have a nice day! :)
