Simple JSON Example

After Adding GSON to your project, you can use it as follows.

main.xml

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >
<TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
       />
</LinearLayout>

JSON_structure.java 
package beanmatrix.JSON;
public class JSON_structure {

              public String name;
              public String date;
              public String[] message;
}


JSONexampleActivity.java
package beanmatrix.JSON;
import android.app.Activity;
import com.google.gson.Gson;
import android.os.Bundle;
import android.widget.TextView;

public class JSONexampleActivity extends Activity {

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        try {
              /* Inflate TextView from the layout */
              TextView text = new TextView (this);
              /* JSON data considered as an example. Generally this data is obtained
              from a web service.*/
              String json = " {" + " \"name\": \"BeanMatrix\", " + " \"message\": [\"My JSON Example\",\"Using GSON For Parsing\"]," + " \"date\": \"17-7-2012\" "+ "}";
              Gson gson = new Gson();
              JSON_structure obj= gson.fromJson(json, JSON_structure.class);
              text.setText("Name: "+ obj.name +"\n\n");
              setContentView(text);
              text.append("Date: "+ obj.date +"\n\n");
              for(int i=0;i<obj.message.length;i++)
              {
                     text.append("Message: "+ obj.message[i] +"\n\n");
              }
              }
              catch(Exception ex){ex.printStackTrace();}
              }
}

Downloading and using external Libraries for JSON

There are many libraries available to parse JSON, be carefull while choosing them. GSON is commonly used because they are quicker than the android classes.

1. Download GSON library from
http://code.google.com/p/google-gson/

2. Now add GSON library to your project, follow the given step.

1. Right click on your project and select properties. Select Java Build Path.Then select Libraries tab.

             2. Now select the option Add external JARs at the right corner.

            3. Browse the path up to downloaded file and press ok.

The External JSON library is ready to use in project.
