Android : android Barcode scanner with outpan database

I want to develop a barcode scanner app in android, i tried using zxing library. the zxing scanner reads a baarcode very well and then asks user for websearch or product search thru google and displays google results. here is what i am doing uptill now

  import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import android.widget.Toast;

import com.google.zxing.integration.android.IntentIntegrator;
import com.google.zxing.integration.android.IntentResult;

public class ScanCodeActivity extends Activity {

    private Button scan;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.scancodelayout);

        scan= (Button)findViewById(R.id.scan_button);

        Button scanBtn  = (Button)findViewById(R.id.scan_button);
        final TextView  formatTxt = (TextView)findViewById(R.id.scan_format);
        final TextView contentTxt = (TextView)findViewById(R.id.scan_content);

        scanBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                IntentIntegrator scanIntegrator = new IntentIntegrator(ScanCodeActivity.this);
                scanIntegrator.initiateScan();
            }
        });
    }

    public void onActivityResult(int requestCode, int resultCode, Intent intent) {
           if (requestCode == 0) {
               IntentResult scanningResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, intent);
               if (resultCode == RESULT_OK) {
                   if (scanningResult != null) {
                       final TextView  formatTxt = (TextView)findViewById(R.id.scan_format);
                       final TextView contentTxt = (TextView)findViewById(R.id.scan_content);
                       String scanContent = scanningResult.getContents();
                       String scanFormat = scanningResult.getFormatName();
                       Toast toast = Toast.makeText(this, "Content:" + scanContent + " Format:" + scanFormat , Toast.LENGTH_LONG);

                       formatTxt.setText("FORMAT: " + scanFormat);
                       contentTxt.setText("CONTENT: " + scanContent);
                     //we have a result
                     }
                   else{
                        Toast toast = Toast.makeText(getApplicationContext(), 
                            "No scan data received!", Toast.LENGTH_SHORT);
                        toast.show();
                    }
               } else if (resultCode == RESULT_CANCELED) {
                  // Handle cancel
                  Log.i("App","Scan unsuccessful");
               }
         }
      }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }
}

what i want to achieve is i want to query a non commercial database. i have found this link

http://www.outpan.com/developers-get-product-data.php

can anyone tell me how to use it in android. i want to scan a particular code and query outpan database with it so that i parse the results into Strings and display them in my android app. user will know which product the barcode represents..
