How do I separate out a JSON object embedded within a string for Android?

Question

I am consuming a string containing JSON, which is passed by an ASP web service to Android. The string that I receive in my Android app is as follows:

GetCustomerListResponse{GetCustomerListResult=[{"VehicleID":"KL-9876","VehicleType":"Nissan","VehicleOwner":"Sanjiva"}]; }

Say I want to get the vehicle type from the JSON string, how do i do that?

My complete Android code is as follows:

package com.example.objectpass;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.widget.ArrayAdapter;
import android.widget.Spinner;
import android.widget.TextView;
import org.ksoap2.*;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.*;

public class MainActivity extends Activity {
    TextView resultA;
    Spinner spinnerC;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        String[] toSpinnerSum;
        toSpinnerSum = new String[9];

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        spinnerC = (Spinner) findViewById(R.id.spinner1);
        resultA = (TextView) findViewById(R.id.textView2);

        final String NAMESPACE = "http://tempuri.org/";
        final String METHOD_NAME = "GetCustomerList";
        final String SOAP_ACTION = "http://tempuri.org/GetCustomerList";
        final String URL = "http://192.168.1.100/WebService4/Service1.asmx";

        SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME);
        SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(
                SoapEnvelope.VER11);
        soapEnvelope.dotNet = true;
        soapEnvelope.setOutputSoapObject(Request);
        AndroidHttpTransport aht = new AndroidHttpTransport(URL);

        try {
            aht.call(SOAP_ACTION, soapEnvelope);
            SoapObject response = (SoapObject) soapEnvelope.bodyIn;

            resultA.setText(response.toString());
        } 
        catch (Exception e) {
            e.printStackTrace();
        }
    }
}

Any help would be greatly appreciated. Thanks

You can use the JSONObject class. Tutorial can be found here. Related question here.

Parse current Json String as:

 //Convert String to JsonArray
 JSONArray jArray = new JSONArray(response.toString());

 for(int i=0;i<jArray.length();i++){
    // get json object from json Array
  JSONObject jsonobj = jArray.getJSONObject(i);

  //get VehicleType from jsonObject
   String str_VehicleType=jsonobj.getString("VehicleType");

  //get VehicleOwner from jsonObject
   String str_VehicleOwner=jsonobj.getString("VehicleOwner");

 }

Hey i made the change as follows: JSONArray jArray = new JSONArray(response.toString()); for(int i=0;i – Kasanova Dec 29 '12 at 15:38
@najjaseven : you will need to put some log and check in log you are getting value from json or not in str_VehicleType variable. – ρяσѕρєя K Dec 29 '12 at 15:42
@najjaseven : what string you are getting in response.toString() ? – ρяσѕρєя K Dec 29 '12 at 15:43
GetCustomerListResponse{GetCustomerListResult=[{"VehicleID":"KL-9876","VehicleType":"Nissan","VehicleOwner":"Sanjiva"}]; } when i insert the json code im not getting anything displayed! – Kasanova Dec 29 '12 at 15:49

@najjaseven : friend this string is not an valid json string .first extract json string from response then pass it in my code – ρяσѕρєя K Dec 29 '12 at 15:53
@najjaseven : use `String tempstr=response.toString().replace("GetCustomerListResponse{GetCustomerListResult=",""); tempstr=tempstr.replace("}]; }","}]");` to replace other part and then pass tempstr to jsonArray – ρяσѕρєя K Dec 29 '12 at 15:55

Here, try this:

final int jsonBeginIdx = response.firstIndexOf("=");
final int jsonEndIdx = response.lastIndexOf(";");

if(jsonBeginIdx > 0 && jsonEndIdx > jsonBeginIdx) {
    final String jsn = response.substring(jsonBeginIdx + 1, jsonEndIdx);
    final JSONObject jsonObj = new JSONObject(json);
} else {
    // deal with malformed response here
}
