I want to ask I have some JSON file returning from WebService I can detect some returning from JSON file but if I want to get JSON array from there cannot do that? But if do that manually like I only use JSON returning from flat data without Asynctask and same returning but can detect.
Problem is: If I use returning JSON file from WebService array cannot be detected on there
But if I use flat data and have same return can detected array

How to parse single object from json

I am working on an Android project where I am using volley to parse the data from JSON. I am able to parse the data if it is an array by following this tutorial. But when I try to parse a single object using getJSONObject, it is returning null. I want to get the value of that particular object.
This is my JSON file:
In the above file I want to retrieve only responseInfo which is a JSON object.

You need to create JSONObject
JSONObject object = new JSONObject(responce);
//get responce code
String query = object.getString("responceCode");

Please use Gson library for json parsing

Keeping some JSON field as String when deserializing using Jackson

I'm using com.fasterxml.jackson.databind with Retrofit to handle the response from the server in my Android app.
Since the JSONObject response is too complicated and contains lots of JSONArray, I want to be able to parse some of those array fields into String instead of creating POJO for each sub-object that those Array could contains.
Is there a way I could just tell Jackson to keep those field as String and not parse them into Entities?

Decode json response in android

I need to decode a json response sent from php in android.
JSON Response
{"VehicleNumber":"1234FB14","Make":"BMW","Model":"X5","Type":"Car","Color":"Black","EngineCapacity":"1800cc","Fuel":"Diesel","DateOfReg":"31-Dec-2013","OwnerNIC":"B1234567890123","serviceArray":[[{"VehicleNumber":"1234FB14","DateOfService":"07-march-2014","Mileage":"1800","Description":"tponggshmbch"}],[{"VehicleNumber":"1234FB14","DateOfService":"07-march-2014","Mileage":"1900","Description":"tponggshmbch"}]]}
The response consists of values for their respective keys and I can retrieve these value by just calling getString(key) in java. {key:value,2D Array[][]}
The problem is that I can't decode the 2D Array being passed here. I get it in a string format in java and if I display it in my android app I can view this:
[[{"VehicleNumber":"1234FB14","DateOfService":"07-march-2014","Mileage":"1800","Description":"tponggshmbch"}],[{"VehicleNumber":"1234FB14","DateOfService":"07-march-2014","Mileage":"1900","Description":"tponggshmbch"}]]
But i need to retrieve all the value from the 2D array.
Any help please.

If Your json is quite big I recommend using gson or Jackson libraries.

Comparing JSONArrays

I am currently using a custom service in my android application to retrieve a JSONArray from a remote database. Once I have retrieved the JSONArray, I would like to compare its contents to another JSONArray which I call 'mostRecent.' If the newly retrieved JSONArray differs from 'mostRecent' then I would like to update 'mostRecent' with the newly retrieved JSONArray. If I am not mistaken, however, the JSONArray equals method compares the instance of the JSONArray object and not the contents, correct? Is there an easy method to compare the contents of two JSONArrays? Thanks for the help!

Use that:
array1.toString().equals(array2.toString());
Maybe you will be able to use even the strings you receive without constructing the JSONArrays, but then you will need to make sure the two are formatted the same way.
