title: What could cause an Android app to run slow on an identical device to one which it runs fast on?
body: <p>I, and a few other of my Android app users, run a Galaxy Nexus. Most of us find the app to be blazing fast, but a couple are reporting that it is unusably slow <strong><em>also on a Galaxy Nexus</em></strong>. I'm shocked to hear them tell me that the buttons, scrolling, etc. are all slow. The main view of the app is a <code>ListView</code> containing many images, textviews, etc. In fact, you can check out <a href="https://play.google.com/store/apps/details?id=com.streamified.streamified" rel="nofollow">the app for free on Google Play</a> if you feel like digging deeper. I'm trying to compile a checklist of what might cause this issue.</p>
  
  <p>Here's what I have so far:</p>
  
  <ul>
  <li>Low memory</li>
  <li>Low disk space</li>
  <li>Uncaught errors</li>
  <li>Rooted device (?)</li>
  </ul>
  
  <p>Any other ideas?</p>
  
  <p>More importantly, is there any way to detect (or even adjust for!) potential problems?</p>
