android http get request in broadcast receiver

Question

I'm new to android and need help, as the question states i want to have a background service that listens to incoming smses(using broadcast receiver?) and then makes a http get request with sms body and phone number for each sms as soon as it arrives(to upload to a web server), trying to do this from scratch, ideas and code examples anyone ? :)

public class ReceiverContainer extends Service{

public SMSreceiver mSMSreceiver;
public IntentFilter mIntentFilter;

@Override
public void onCreate()
{
super.onCreate();

//SMS event receiver
mSMSreceiver = new SMSreceiver();
mIntentFilter = new IntentFilter();
mIntentFilter.addAction("android.provider.Telephony.SMS_RECEIVED");
registerReceiver(mSMSreceiver, mIntentFilter);
}

@Override
public void onDestroy()
{
super.onDestroy();

// Unregister the SMS receiver
unregisterReceiver(mSMSreceiver);
mSMSreceiver = null;
}

@Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}

public class SMSreceiver extends BroadcastReceiver
{
 public void Action(Context context,Intent intent) throws ClientProtocolException, URISyntaxException, IOException
    {
     Bundle myBundle = intent.getExtras();
     SmsMessage [] messages = null;
     String strMessage = "";
     String msgFrom = "";
     String msgText = "";

     if (myBundle != null)
     {
         Object [] pdus = (Object[]) myBundle.get("pdus");
         messages = new SmsMessage[pdus.length];

         for (int i = 0; i < messages.length; i++)
         {
             messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
             strMessage += "SMS From: " + messages[i].getOriginatingAddress();
             msgFrom += messages[i].getOriginatingAddress();
             strMessage += " : ";
             strMessage += messages[i].getMessageBody();
             msgText += messages[i].getMessageBody();
             strMessage += "\n";
         }

         Toast.makeText(context, strMessage, Toast.LENGTH_SHORT).show();

         uploadMessage(context,msgFrom,msgText);

     }
    }

@Override
public void onReceive(Context context, Intent intent)
{
        try {
            Action(context,intent);
        } catch (ClientProtocolException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (URISyntaxException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
}

}

public void uploadMessage(Context context,String number,String msg) throws URISyntaxException,   ClientProtocolException, IOException
{

HttpResponse response = null;
HttpClient client = new DefaultHttpClient();


Uri.Builder path = new Uri.Builder();
path.scheme("http");
path.authority("technonectar11.com");
path.path("sms");
path.appendQueryParameter("fromno" , number);
path.appendQueryParameter("text" , msg);
path.appendQueryParameter("uname" , "vijay");

HttpGet request = new HttpGet(path.build().toString());     
//request.setURI(new URI("http://www.technonectar11.com/sms/insertsms?fromno="+number+"&text="+msg+"&uname=vijay"));
response = client.execute(request);

String result = convertStreamToString(response.getEntity().getContent());

Toast.makeText(context, result, Toast.LENGTH_SHORT).show();

}

public static String convertStreamToString(InputStream inputStream) throws IOException
{
if (inputStream != null)
{
    Writer writer = new StringWriter();

    char[] buffer = new char[1024];
    try
    {
        Reader reader = new BufferedReader(new InputStreamReader(inputStream, "UTF-8"),1024);
        int n;
        while ((n = reader.read(buffer)) != -1)
        {
            writer.write(buffer, 0, n);
        }
    }
    finally
    {
        inputStream.close();
    }
    return writer.toString();
}
else
{
    return "";
}

} }

this is my code in its entirety, but the upload message function does not work

Turns out that I'm not allowed to perform Network Operations on the main thread. It gives me a NetworkOnMainThreadException. I have to use IntentService/AsyncTasks/Handler for this one.
