This project I've done with image in my drawable but now I want to get image url from JSON by using Asynctask and display it. and I make php that provide a json string like below.
I want to get path of image(url) by using AsyncTask from JSON.
I want to use data from json instead of public mThumbId = {...};
{"count":"28","data":
[{"id":"1",
"first_name":"man",
"last_name":"woman",
"username":"man",
