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",
"password":"4f70432e636970de9929bcc6f1b72412",
"email":"

"url":"http://vulcan.wr.usgs.gov/Imgs/Jpg/MSH/Images/MSH64_aerial_view_st_helens_from_NE_09-64_med.jpg"},
{"id":"2",
