android server post data

I am new to android networking and would like to find the best solution/source that would help me learn the same. I have a working android application but i want to include network services that can get and send data to the webserver. While i was searching for the same i found link ( http://www.helloandroid.com/tutorials/connecting-mysql-database ) which dont produce any results. I also found that SOAP or REST (with android) are probably recommended methods, if so please give complete tutorials to learn the same ( i have no prior knowledge on webservices). In my application I would be required to send data to the server and receive data from the servers sql

Tha开发者_开发问答nk you

This is for post data on server,

  HttpClient httpclient = new DefaultHttpClient();
  HttpPost httppost = new HttpPost(url);  
  httppost.addHeader("Content-Type", "application/x-www-form-urlencoded");
  httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs,HTTP.UTF_8));
     // Execute HTTP Post Request 
  HttpResponse response = httpclient.execute(httppost);         
     // get response entity 
  HttpEntity entity = response.getEntity();          
     // convert entity response to string  
  if (entity != null) 
     {      
      InputStream is = entity.getContent();     
       // convert stream to string    
       result = convertStreamToString(is);      
       result = result.replace("\n", "");     

}
