Parse JSON format data from SOAP Web service in Android

As JSON is so much preferred for android which is said to be easier to parse, faster and power saving lets try a simple example on JSON parsing. In this example we will learn how to parse JSON data from SOAP web service and use in our android program.

Check this post if your service is in XML format.

Lets take a simple JSON format data.
Example: 

[
  {
      "J_Name" : "yashwanth",
      "J_Id" : "04",
      "J_Place":"Hosur",
      "J_Phone":"9876543210"
  }
]


Step 1 : Create a new project in Eclipse IDE File ⇒ New ⇒ Android Application Project and fill all the required details.

Step 2 : In your layout file place some text fields and align it as required.


Step 3 : Add Internet Permission in your project manifest file .

AndroidManifest.xml : 

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="www.andygeeks.blogspot.com"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="19" />
<uses-permission android:name="android.permission.INTERNET"/>

<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="www.andygeeks.blogspot.com.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>

</manifest>

Step 4 : Include the KSOAP2 jar file in to your project. Right click project ⇒ Properties ⇒ Java build path ⇒ Libraries Tab ⇒ Add External Jars ⇒ browse and add KSOAP2 Jar file and gson Jar file.

Step 5 : Now call the web service and get details with asynctask. Paste this below code in your MainActivity class file.

MainActivity.java :

package www.andygeeks.blogspot.com;

SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;

envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
androidHttpTransport.debug = true;

try {
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapPrimitive response = (SoapPrimitive) envelope.getResponse();

String responseJSON=response.toString();
