how to plal video listview from json file

[Hallo91]

I have an exoplayer example which plays an Iptv live stream from a link.
Full code has only 1 java + xml activity, now i want to use a json file to load a list of items "links" , and when i click on item, takes me to the exoplayer activity . so i did this :

1. i downloaded a json code and customize it as i want with title + discription(discription as link).

i want to click on discription item, to play it's video link, any help please :


Here is my json file:

{
"contacts": [
{
"title": "video 1",
"discription": "http://117.196.231.0:86/hls/10.m3u8"
},
{
"title": "video 2",
"discription": "http://117.196.212.0:86/hls/54.m3u8"
}
]
}
