Universal Music Player with own JSON and Youtube Audio Library

What is the complete URL of Jazz_In_Paris.mp3 and album_art.jpg

http://storage.googleapis.com/automotive-media/album_art.jpg

http://storage.googleapis.com/automotive-media/The_Messenger.mp3

Where they have used site object "site" : "https://www.youtube.com/audiolibrary/music" in application (in which class and where)

this url not used any where in app.

Where I have to make changes in my code, If I would like to get JSON from my own Server "http://www.domain.com/services/music.json"

yes, you can use same json for your app but just change path to your server(just create same json format)

How can I create my own Youtube Audio Library, Like in my Library I would like to add my favourite youtube songs

Universal Music Player: use Google storage client to store music files but you can also create own you tube channel and make private video. use it in your app

EDITED:

"site" json object is useless. this object is json because of previous version of app they have used that. currently not.

youtube channel and Google storage both are different thing. Google storage mainly used to store files which we are able to use in our app.

in you tube every one can upload video which is private/public(if you are going to use that in your app then use private). for more detail check you support articals

i suggest you to use Google Storage API or you can also upload files on your own server!
