while trying to execute...

package com.test.readurl;

import java.util.ArrayList;
import java.util.List;

import org.apache.http.NameValuePair;
import org.apache.http.message.BasicNameValuePair;
import org.json.JSONException;
import org.json.JSONObject;

import android.os.Bundle;
import android.app.Activity;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.widget.Toast;

public class MainActivity extends Activity {
private static final String url_detials = "http://foefinder.com/api/details.php";

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}

public void button1_onClick(View view){
    //Toast.makeText(getApplicationContext(), "Hello Test", Toast.LENGTH_LONG).show();

     // JSON parser class
    JSONParser jsonParser = new JSONParser();

    // Building Parameters
    List<NameValuePair> params = new ArrayList<NameValuePair>();
    String pid = null;
    params.add(new BasicNameValuePair("pid", pid));

    // getting product details by making HTTP request
    // Note that product details url will use GET request
    JSONObject json = jsonParser.makeHttpRequest(
            url_detials, "GET", params);

    // check your log for json response
    Log.d("Single Product Details", json.toString());

} 

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.activity_main, menu);
    return true;
}
}

Am trying to read a URL from this app on a button click... but not able to do so... can some one help me with this ?

You're doing an HTTP request (JSONObject json = jsonParser.makeHttpRequest( url_detials, "GET", params);) on the UI thread.
Move this stuff in an AsyncTask.

How should I modify this ?

You should use AsyncTask. Android doesnt allow http request running on the main UI thread.

JSONObject json = jsonParser.makeHttpRequest(url_detials, "GET", params);

If you want a quick test, you can add this in your onCreate() method to bypass the exception*

StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();

StrictMode.setThreadPolicy(policy);

I wont recommend using StrictMode though!

Because you are request JSONObject in UI Thread. you must have to use in AsycTask like This. Or You should use runOnUiThread like This..
