Question

I am developing the application which is also downloading and saving mp3 files on SD card (it isn’t main task of the application). These files I am using only in the application. Is some possible way to make these files invisible for users, especially for their audio players? For example when I open embedded player on Sony phones, so there are these mp3 files automaticly loaded – I don’t want it.Thank you for help. Lukas

Answer 1

You can create .nomedia empty file in the folder where you saved your mp3 files:

Include an empty file named .nomedia in your external files directory
(note the dot prefix in the filename). This will prevent Android’s
media scanner from reading your media files and including them in apps
like Gallery or Music.
