title: Android - exception SuperNotCalledException in an Activity where I do call super
body: <p>I have this exception:</p>
  
  <pre><code>android.app.SuperNotCalledException: Activity {com.problemio/com.problemio.SupportActivity} did not call through to super.onDestroy()

  </code></pre>
  
  <p>But I have this method in the Activity:</p>
  
  <pre><code>@Override
  public void onDestroy() 
  {
      super.onDestroy();
  
      // very important:
      if (mHelper != null) mHelper.dispose();
      mHelper = null;
  }    
  </code></pre>
  
  <p>Why would this exception happen? It seems that I do call super.onDestroy()</p>
  
  <p>Thanks!</p>
