I have Json through which i have to retrieve objects but unable to retrieve. I have used multiple objects also to retrieve but no success. JSON:

{
    "status": 1,
    "data": [{
        "restaurent_id": "1",
        "user_id": "6",
        "zone_id": "1",
        "restaurentAddress": {
            "restaurent_address_id": "1"
        },
        "restaurentInfo": {
            "restaurent_info_id": "1",
            "restaurent_bussiness_owner_name": "Vijay"
        },
        "restaurentSetting": {
            "restaurent_setting_id": "1",
            "minimum_purcase": "200",
            "payment_method_id": "1",
            "title": "Best Hotel"
        },
        "zone": {
            "zone_id": "1",
            "by_zipcode": "1"
        }

    }]
}

and i want to fetch restaurentAddress and restaurentInfo

MY mainActivity.java file

package com.example.premi.jsonlist;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

import org.json.JSONArray;

import org.json.JSONObject;

public class MainActivity extends Activity {
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        TextView output = (TextView) findViewById(R.id.textView1);
        String strJson="{\n" +
                "\t\"status\": 1,\n" +
                "\t\"data\": [{\n" +
                "\t\t\"restaurent_id\": \"1\",\n" +
                "\t\t\"user_id\": \"6\",\n" +

                "\t\t\t\"minimum_purcase\": \"200\",\n" +

                "\n" +
                "\t}]\n" +
                "}";
        String dataoutput = "";
        try {
            JSONObject  jsonRootObject = new JSONObject(strJson);

            //Get the instance of JSONArray that contains JSONObjects
            JSONObject status = jsonRootObject.optJSONObject("status");
            JSONArray Dataarray =status.getJSONArray("data");

            //Iterate the jsonArray and print the info of JSONObjects

                JSONObject jsonObject = Dataarray.getJSONObject(i);
JSONObject Data = jsonObject.getJSONObject("restaurentAddress");

                for(int j = 0 ; j < Data.length(); j++){
                    JSONObject GetData =Data.getJSONObject(String.valueOf(j));
                int id = Integer.parseInt(GetData.getString("restaurent_address_id"));
                String postcode = GetData.getString("postcode");
                String addresss = GetData.getString("restaurent_address");


                dataoutput += " : \n id= "+ id +" \n postcode= "+ postcode +" \n address= "+ addresss +" \n ";
            }}
            output.setText(dataoutput);
        } catch (JSONException e) {e.printStackTrace();}
    }
}

Try this out:

try {
    JSONObject object = (JSONObject) new JSONTokener(YOUR_JSON_STRING).nextValue();
    String restaurentAddressId = object.getJSONArray("data").getJSONObject(0).getJSONObject("restaurentAddress").getString("restaurent_address_id");
    String restaurentInfoId = object.getJSONArray("data").getJSONObject(1).getJSONObject("restaurentInfo").getString("restaurent_info_id");
    String restaurentBizOwnerName = object.getJSONArray("data").getJSONObject(1).getJSONObject("restaurentInfo").getString("restaurent_business_owner_name");

}
catch (JSONException e) {
}

It seems like you are trying to use a method from an API level, API 19 for ArrayMap, that isn't supported by the device you're testing it on. I'm not familiar with this issue but check out stackoverflow.com/questions/36812913/… and stackoverflow.com/questions/36930200/…

I need one more help if i am paasing json locally it is working and when i m using as api (URL) its giving error its showing blank... what will be the reason ? is their any way to first store json locally then retrieve ?

not sure what you mean, but it needs to be in JSON string format for you to parse it. And you can store the JSON string in SharedPreferences to later on retrieve it if I understand you correctly.

Its Done I tried this

   try {
        JSONObject  jsonRootObject = new JSONObject(strJson);

        //Get the instance of JSONArray that contains JSONObjects
        JSONArray mainnode =jsonRootObject.getJSONArray("data");

        //Iterate the jsonArray and print the info of JSONObjects
        for(int i=0; i < mainnode.length(); i++){
            JSONObject jsonObject = mainnode.getJSONObject(i);
            JSONObject Data = jsonObject.getJSONObject("restaurentInfo");
                int id = Integer.parseInt(Data.getString("restaurent_info_id"));
                String postcode = Data.getString("restaurent_phone_number");
                String addresss = Data.getString("restaurent_bussiness_owner_name");


                dataoutput += " : \n restaurent_id= "+ id +" \n restaurent_info_id= "+ postcode +" \n restaurent_address_id= "+ addresss +" \n ";

        }
        output.setText(dataoutput);
    } catch (JSONException e) {e.printStackTrace();}
}

I just removed Status Object

and another for loop Thanks For the Help Got little Bit Help from You :)
