I Cannot Add New Folder At Res Directory

I need to create folder at res this folder has sound but i couldn't and i don't whey ?

Solution 1:

We must create a raw folder and then add your mp3

You access to your file that way :

getResources().openRawResource(R.raw.sound);

Solution 2:

Your mp3 file should be added to res/raw (you may need to create this). Good luck !
