eclipse android development, implementing json list - android

I'm working on an eclipse android project, it's a news app..
The objective is to display the list of news which I must import from an online JSON file and display that list in the activity
let's say I want to display the last 3 news..
and take this as an example : " http://www.tripoliscope.com/api/get_date_posts/?order=DESC&date=2014-07-08&count=3 "
How can I get some data from that JSON and display it in a list?
I've been searching for 3 days and no answer found.

Here we have some examples

Rss to Json Api Android Studio

I'm working on an Android studio project and till now I have successfully added some json feeds in my app.
However , i need to add one rss feed also to my app.
The easiest solution to me is to make an online conversion of the rss feed to json feed so I can parse my data with the previous code.
Google API is going to stop by 15th Dec 16' and yahoo query is down .
What would you suggest?
I'm about 5 hours now , trying to find a solution.
*I tried rss2json.com however after the first time fetching the data , the feed is refreshed after a long , very long time.
You can create your own toJson(xml) method and use XmlPullParser to read and retrieve the data you need to create a new Json object. I'm guessing you want to use your Json parser instead, but at this point you already have the data that you would be using for your application. So, just use an XML parser instead =).

Android application which can parse json recieved from server into meaningful datasets

I want to develop an android application which parses json data into some meaningful data sets and accordingly display them into the UI .
I need suggestions on how to go about it.
PS : i have 0 idea of the available options to chose , so different ways to do the same would help me a lot , since i am new to it
Thanks in advance
You can use gson for parsing the data together with some network library like volley or can use retrofit which provide direct parsing with the help of gson and other lib.
To accomplish this you first need to create some relevant Java pojo
For corresponding json dataset , so that you can use it .
You can generate pojo from this website very easily for any json data

how do i get the website in json format?

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.
For future readers :
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.

Simple Android JSON Parsing

Hello, I am a newbie to android development
I am trying to understand how to parse JSON in android activity
I am not using anything such as PHP etc
I am using NODEJS on server in AWS to generate JSON
I have a JSON ::
{"1":"Hello","2":"World"}
This JSON is coming from an AWS server i have hosted my application
How to parse the JSON data for above JSON ?
How to populate to an android activity ?
PS:: Any links that would help me understand this concept would also be helpful
Thanks,
In the most basic form, you can parse JSON by simply creating a JSON object and passing the string representation of the JSON object to the constructor, like so...
JSONObject myJson = new JSONObject("{\"1\":\"Hello\",\"2\":\"World\"}");
Read the docs on this class for more info on how to extract data from objects and etc... https://developer.android.com/reference/org/json/JSONObject.html
A more abstract way of parsing can be done via the GSON library. In a nutshell, GSON has the ability to take your JSON response and parse it into a Java object for you so that you don't have to do it yourself.
Admittedly using GSON can save a good amount of time from writing code to parse yourself, however, I would probably rather go the JSONObject route if you're new to this.

get data using webservice android

I have data on a server which stores name and images.
I want to retrieve that from server and display in table layout on Android.
I wonder which is the best xmlparsing or json parsing for that purpose.
Is there any tutorial for that?
if($_REQUEST['mode']=="get")
{
$result = mysql_query("SELECT state,imageurl FROM `pic_upload`");
while($row = mysql_fetch_assoc($result))
{
$output=$row;
print(json_encode($output));
}
mysql_close;
}
using this i will get data from server but how to get data using xml parsing any one know
It seems that json_encode($output) will produce a JSON output, so you should use Android's JSON API (org.json).
A quite recent tutorial is located at http://www.androidhive.info/2012/01/android-json-parsing-tutorial/ (also showing how to put retrieved elements on a list), but you will find many simply googling for Android and JSON.
If it is a simple item and no huge list, the org.json packages that come with Android are perfect.
Have a look at that Tutorial from Lars Vogel to get started.
