i'm new to android coding, and i was wondering if you can get a JSON from a webpage with Get Request(eg. http://xxx.xx.xx.xxx/test) and get specific fields in that JSON?
And How can I Do that?
Yes, you can use the volley library or asynctask for connecting to a webservice and getting the JSON objects/array or string.

I want to parse website using retrofit, but I don't know how to create POJO.
And I don't have a json.

This is the website where I want to parse information.
if your website does not have an API or anyway to get JSON data then you should consider Web Scraping. You cant make POJO/Models without JSON Data
i am building my first intro app, i have a doubt, is it possible to send a request to server and get the response as a json and parse it, if so how do i achieve it using retrofit2 in android. But if retrofit is not the right thing for it then what do i use?
Thanks in advance!
i need to get a website (any website ) in json format to use it with android and json parser to get data and if possible that the website include images to be able to download data and images using json parser.
i have been searching about 2 days without any success, its my first time that i use json so i do know where to search and how to search.
what i need is a website to make a test on it that will be available in json format
anyone can help me ???
i will appreciate that.
Use http://www.jsontest.com/ to get JSON from that website.
Read there and for example if you call http://ip.jsontest.com/ you will get a JSON response as {"ip": "203.92.62.242"} then you can parse them in your android application.

Facebook programmers provide the json format for each request.
All you have to do is :
If the facebook page url is : http://www.facebook.com/youtube
To get json format of page, request this : http://graph.facebook.com/youtube
I suggest to read that :
Usually standard web service today provide data in at least two format: json and xml for each endpoint (url), you just add .xml or .json extension to the requested url.
But most of the time you don't have to do that, common web services today always provide json data because it's defined in RESTFul rules. If they dont, you can't get the json. The case is same for you, just ask the developer for API docs.

what is the GSON. can you tell why GSON use in this.????
I am new in json. if you know about json please guide me to solve this problem.
GSON is a Java library to convert java objects to JSON and vice-versa. You don't need it unless you have some complex JSON structure. For simple objects you can easily construct the JSON string yourself.
I want to know how to parse the web service response data in android .Actually i m accessing the .net web service.I can get a result of some complex type.i want to know how to retrive a particular value from this complex type.Is there is any parser avilable to parse the content of the response or else we have to parse manually? If u have any code snippet pls bring me.
First of all - what content type you are talking about? XML and JSON are supported I believe. I've been using just plain HttpClient to get the responses
if you need to parse XML response, see here:
