title: Using PHP sessions with my android application to login
body: <p>I am trying to make a login script for my android application, the script will send my email and password to the PHP server, verify the login and then create a PHP session so that the user stays logged in. This is my code,</p>
  
  <pre><code>HttpPost httppost = new HttpPost("http://server.com/login.php");
  // Create a new HttpClient and Post Header
  HttpClient httpclient = new DefaultHttpClient();
  
  public String login() {
  
      String userID = "";
  
      try {
          // Add your data
          List&lt;NameValuePair&gt; nameValuePairs = new ArrayList&lt;NameValuePair&gt;(2);
          nameValuePairs.add(new BasicNameValuePair("email", "e@e.com"));
          nameValuePairs.add(new BasicNameValuePair("password", "admin"));
          httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
  
          // Execute HTTP Post Request
          HttpResponse response = httpclient.execute(httppost);
  
          userID = EntityUtils.toString(response.getEntity());
          //Log.v("Login response", "" + userID);
  
  
  
      } catch (ClientProtocolException e) {
          // TODO Auto-generated catch block
      } catch (IOException e) {
          // TODO Auto-generated catch block
      }
  
      return userID;
  } 
  </code></pre>
  
  <p>This script successfully sends data to my server and my PHP successfully logs the user on. I have placed "HttpClient httpclient = new DefaultHttpClient();" outside my main login method. This has helped store the session until I call upon another class, then it just resets the session again. So I am wondering how I can alter the code so that "httpclient" is somehow stored so I can keep the session and stay logged into my server. Thank you!</p>
