title: Android activity doesn't show up
body: <p>I'm trying to start an activity (Act2) from another activity(Act1), and it doesn't happen like it should.</p>
  
  <p>In the debugger, I can see that as a result of calling startActivity() the method <strong>onCreate()</strong> of act2 is <strong>called 3 times</strong> (!!...), no error shows, or exception caught, and unfortunatly the desired UI doesn't show.</p>
  
  <p>for trying to understand better where is the problem, I run the next 2 tests that showed expected normal behavior:</p>
  
  <ol>
  <li>when I modify Act1 to start Act3 (instead of Act2, just for
  understanding if its a problemof Act1), then act3 shows its UI as expected.</li>
  <li>when Act4 start Act2, it runs as expected, and show the UI on the screen.</li>
  </ol>
  
  <p>As to the code, I start the activity in the common way of:</p>
  
  <pre><code>Intent intent = new Intent(Act1.this, Act2.class);
  startActivity(intent);
  </code></pre>
  
  <p>Anyone faced such thing?</p>
  
  <p>Thanks.</p>
