get response from php and save in a file android

I'm trying to make a request from android to a PHP file. After that, i need to save the response generated by the PHP (a single code) into a file so i can read it next times without having to make the request again. For the request, i created a new method which reads as follows:

> private String deviceIdHttpGetter(){
>           HttpHandler handler =   new HttpHandler();
>           String code=handler.post("http://www.cafegourmet.es/newUser.php");
>           Toast.makeText(getApplicationContext(), "your code is " + code, Toast.LENGTH_SHORT).show();
>               return code;
>               
>           }

I also moddified the HttpHandler post() method so i can get the code and return it, so now it looks like this:

>   public String post(String postURL){
>           try {
>               HttpClient client = new DefaultHttpClient();
>               HttpPost post = new HttpPost(postURL);
>               HttpResponse response = client.execute(post);
>               HttpEntity ent = response.getEntity();
>               String text = EntityUtils.toString(ent);
>               return text;
>           }
>     
>           catch(Exception e) { return e.getMessage();} 
>     }

The PHP, right now, reads as follows:

<?php $code = 12345; echo $code; ?>

Well... the problem is that, I don't know why, but I ALWAYS see the Toast as if no code were recieved ("your code is "), but when I access this PHP from the explorer, I always get the new code I need, therefore i cannot save the data to a file.

Any suggestions? Thanks in advance to everyone

Here's the code with the problem solved, hope it helps someone:

First, the code for calling the async in the main activity reads as following:

private String deviceIdHttpGetter(){
        try
        {
        AsyncHttpDeviceId asyncId = new AsyncHttpDeviceId();
        return asyncId.execute("http://www.cafegourmet.es/newUser.php").get();
        }
        catch(Exception e){
            return e.toString();
        }
    }
}

And the Async finally reads as following:

public class AsyncHttpDeviceId extends AsyncTask<String, Integer, String> {
    String code="";

     public AsyncHttpDeviceId () {
        }

        /**
         * background
         */
     protected String doInBackground(String... posturl ) {
               HttpClient httpclient = new DefaultHttpClient();
               HttpResponse response;
               String responseString = null;
               try {
                   response = httpclient.execute(new HttpGet(posturl[0]));
                   StatusLine statusLine = response.getStatusLine();
                   if(statusLine.getStatusCode() == HttpStatus.SC_OK){
                       ByteArrayOutputStream out = new ByteArrayOutputStream();
                       response.getEntity().writeTo(out);
                       responseString = out.toString();
                       out.close();
                   } else{
                       //Closes the connection.
                       response.getEntity().getContent().close();
                       throw new IOException(statusLine.getReasonPhrase());
                   }
               } catch (ClientProtocolException e) {
                   return e.toString();
               } catch (IOException e) {
                   return e.getMessage();
               }
               return responseString;
      }
      protected void onPostExecute(String result) {
            code=result;
      }
}

Hope this helps someone someday.
