Android: Comment envoyer une requête http via le service toutes les 10 secondes

J'ai besoin de recevoir un statut du serveur toutes les 10 secondes.

J'ai essayé de le faire par l'envoi d'une requête http via le service.

Le problème est que mon code s'exécute qu'une seule fois.

C'est le code de mon service:

public class ServiceStatusUpdate extends Service {
@Override
public IBinder onBind(Intent intent) {
//TODO Auto-generated method stub
return null;
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
while(true)
{
try {
Thread.sleep(10000);
} catch (InterruptedException e) {
new DoBackgroundTask().execute(Utilities.QUERYstatus);
e.printStackTrace();
}
return START_STICKY;            
}
}
private class DoBackgroundTask extends AsyncTask<String, String, String> {
@Override
protected String doInBackground(String... params) {
String response = "";
String dataToSend = params[0];
Log.i("FROM STATS SERVICE DoBackgroundTask", dataToSend);
HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(Utilities.AGENT_URL);
try {
httpPost.setEntity(new StringEntity(dataToSend, "UTF-8"));
//Set up the header types needed to properly transfer JSON
httpPost.setHeader("Content-Type", "application/json");
httpPost.setHeader("Accept-Encoding", "application/json");
httpPost.setHeader("Accept-Language", "en-US");
//Execute POST
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity responseEntity = httpResponse.getEntity();
if (responseEntity != null) {
response = EntityUtils.toString(responseEntity);
} else {
response = "{\"NO DATA:\"NO DATA\"}";
}
} catch (ClientProtocolException e) {
response = "{\"ERROR\":" + e.getMessage().toString() + "}";
} catch (IOException e) {
response = "{\"ERROR\":" + e.getMessage().toString() + "}";
}
return response;
}
@Override
protected void onPostExecute(String result) {
Utilities.STATUS = result;
Log.i("FROM STATUS SERVICE: STATUS IS:", Utilities.STATUS);
super.onPostExecute(result);
}
}
}

Merci beaucoup
Avi
