Android - WebView i pobieranie danych w tle

Witam serdecznie,
Mam aplikację webview uruchomioną na pełnym ekranie i chciałbym w oddzielnym wątku (tam żeby nie wyskakiwał błąd mówiązcy iż aplikacja nie odpowiada) uruchomić POST'a do skryptu PHP.

Aktualnie mam taki kod:
MenuActivity.java

 
package butterfly.menu;

import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.content.res.Configuration;
import android.os.Bundle;
import android.view.KeyEvent;
import android.webkit.WebView;
import android.webkit.WebViewClient;

public class MenuActivity extends Activity {
	WebView mWebView;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) { 
    	super.onCreate(savedInstanceState);
    	
    	startService(new Intent(this, OnAlarmReceiver.class));
        
    	setContentView(R.layout.main);
        if (savedInstanceState != null)
            ((WebView)findViewById(R.id.webview)).restoreState(savedInstanceState);

        mWebView = (WebView) findViewById(R.id.webview);
        mWebView.getSettings().setJavaScriptEnabled(true); // włączenie JS
        mWebView.getSettings().setSupportZoom(false); // blokada ZOOMu
        
        
        
        //mWebView.loadUrl("http://onet.home.pl/"); // strona do wyświetlenia
        mWebView.setWebViewClient(new MenuClient());
        if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT)
        {
            mWebView.loadUrl("http://onet.home.pl/");
        }

        else if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE)
        {
            mWebView.loadUrl("http://onet.home.pl/");
        }
    }
    private class MenuClient extends WebViewClient {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);
            return true;
        }
    }
    protected void onSaveInstanceState(Bundle outState) {
    	mWebView.saveState(outState);
     }
    
    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
        if ((keyCode == KeyEvent.KEYCODE_HOME || keyCode == KeyEvent.KEYCODE_BACK || keyCode == KeyEvent.KEYCODE_VOLUME_DOWN || keyCode == KeyEvent.KEYCODE_VOLUME_UP || keyCode == KeyEvent.KEYCODE_CALL || keyCode == KeyEvent.KEYCODE_POWER || keyCode == KeyEvent.KEYCODE_CAMERA || keyCode == KeyEvent.KEYCODE_CLEAR || keyCode == KeyEvent.KEYCODE_ENTER || keyCode == KeyEvent.KEYCODE_POWER)) {
            //mWebView.goBack();
            return false;
        }
        return super.onKeyDown(keyCode, event);
    }
    
    @Override
	public void onConfigurationChanged(Configuration newConfig) {
    	if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT)
        {
            mWebView.loadUrl("http://onet.home.pl/");
        }

        else if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE)
        {
            mWebView.loadUrl("http://onet.home.pl/");
        }
		super.onConfigurationChanged(newConfig);
	} 
    public void onReceive(Context context, Intent intent) { 
    	startService(new Intent(this, OnAlarmReceiver.class));
    	super.onReceive(Context context, Intent intent);
    } 

} 

oraz OnAlarmReciver.java

 
package butterfly.menu;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

import org.apache.http.HttpResponse;
import org.apache.http.NameValuePair;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.message.BasicNameValuePair;

import android.app.Service;
import android.content.Intent;
import android.os.IBinder;

public class OnAlarmReceiver extends Service {
	@Override
	public IBinder onBind(Intent intent) {
		return null;
	}

	@Override
	public void onCreate() {
		HttpClient httpclient = new DefaultHttpClient();
	    HttpPost httppost = new HttpPost("http://www.yoursite.com/script.php");

	    try {
	        // Add your data
	        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
	        nameValuePairs.add(new BasicNameValuePair("id", "12345"));
	        nameValuePairs.add(new BasicNameValuePair("stringdata", "AndDev is Cool!"));
	        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

	        // Execute HTTP Post Request
	        HttpResponse response = httpclient.execute(httppost);
	        
	    } catch (ClientProtocolException e) {
	        // TODO Auto-generated catch block
	    } catch (IOException e) {
	        // TODO Auto-generated catch block
	    }
        }
}

Ale nie wiem czy dobrze to robię :( coś wywołanie tego wątku nie chce mi za bardzo działać... :( Wiecie może dlaczego?

Z góry dziękuje za pomoc,
Northwest
