title: ChooserActivity has leaked IntentReceiver com.android.internal.app.ResolverActivity
body: <p>I'm trying to open a xml file with default application on the phone when clicking a button of my app. after google i found and followed this: <a href="http://www.androidsnippets.com/open-file-with-default-application-using-intents" rel="nofollow">http://www.androidsnippets.com/open-file-with-default-application-using-intents</a> , my code is just as:</p>
  
  <pre><code>Intent intent = new Intent();
  intent.setAction(Intent.ACTION_VIEW);
  intent.setDataAndType(Uri.fromFile(_file), "application/*"); 
  startActivity(intent);
  </code></pre>
  
  <p>it works on my phone, but the logcat got some errors:</p>
