title: How to make a conditional to know if it is the first time you run the activity
body: <p>I would like to know how to set a conditional: If this is the first time you start the activity (every time you start the application) do something, and if I already began earlier do something else. Something like:</p>
  
  <pre><code>If (firstTime) {
  }
  else {
  bundle = getIntent () getExtras ().;
  count = bundle.getInt ("countAnterior");
  }
  </code></pre>
