title: Updating date from SimpleDateFormat Android?
body: <p>I've used <code>SimpleDateFormat</code> in my Android app. Like this:</p>
  
  <pre><code>final TextView date = (TextView) findViewById(R.id.date);
  
  long datesdf = System.currentTimeMillis();
  
  SimpleDateFormat sdf = new SimpleDateFormat("dd MMMM, yyyy");
  String dateString = sdf.format(datesdf);
  date.setText(dateString);
  date.setTextSize(17);
  </code></pre>
  
  <p>By which I get output example:
  <strong>01 May, 2015</strong></p>
  
  <p>But the problem is the date, month or year doesn't get updated, what's wrong with it? Thanks in advance!</p>
