title: Make HTTP requests with progress bar, before opening a new Activity: how?
body: <p>I have a piece of code that sets some network IP cameras parameters by simply calling some URLs. URLs are (to simplify) in this format "http://mydomain.com:portnumber/setalarm.cgi" and I use a normal HttpGet / HttpResponse mechanism to call URL and get result status (200 if it is good, other if bad).
  Now: as URL to be called are 8 or more, in sequence (I use for loop), I would like to display a progress bar (or the simple progress indicator) to let the user know that the different URL calls are being performed. When all of the 8 calls are done, I would like a new Actity to be displayed with the result (OK, or KO with the list of KO cams).</p>
  
  <p>I've tried many solutions, found on this site, but none of those where successful (Threads, progressbar , dialog bar, Asynchronous task, etc.). Either I get exceptions, or the bar does not show, or the new Activity display before the completion of the process.</p>
  
  <p>Could anyone help ? This is the relevant part of my code now:</p>
  
  <pre><code>public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.mainlayout);
  
      // ON button
      Button myButton1 = (Button) findViewById (R.id.button1);
      myButton1.setOnClickListener(new OnClickListener() {            
  
          public void onClick(final View arg0) {
  
              intGoodCamera = 0;
              intBadCamera = 0;
  
              for (int i = 0; i&lt;intNumCam; i++) {
  
                  System.out.println (intStartingPortNb+i);
  
                  String myurl = strIPAddress + ":" + (intStartingPortNb+i) + strSuffixSetAlarmOn;
                  HttpClient httpClient = new DefaultHttpClient();
                  HttpContext localContext = new BasicHttpContext();
                  HttpGet httpGet = new HttpGet(myurl);
                  HttpResponse response = null;
                  try {
  
                      response = httpClient.execute(httpGet, localContext);
                      System.out.println (response.getStatusLine().getStatusCode());
                      if (response.getStatusLine().getStatusCode() == 200) 
                          intGoodCamera++;
                      else {
                          intBadCamera++;
                      }
                  } catch (ClientProtocolException e) {
                      e.printStackTrace();
                  } catch (IOException e) {
                      e.printStackTrace();
                  }
              }
  
              System.out.println ("OK: "+intGoodCamera + " KO: "+ intBadCamera);
              Intent nextIntent = new Intent(MainActivity.this, Results.class);
              MainActivity.this.startActivity(nextIntent);
          }
      });
