Yes, I tried that too, but it didn’t work for me. Don’t know why… 
But I am good with the current result. 
The guy that uploaded the folder I was talking about asked me very precisely what folder worked and what folder didn’t. He seemed to be in charge with Android Processing and he was the one that made changes to the initial folder, so I believe he will make the necessary adjustments for Android Sound to work better in the future!
So I recommend all of you to put questions on Github or anywhere if you have issues of any kind, because all improvements can be possible if you tell exactly what are you dealing with!
Wishing you all the best,
Sammy
