title: A simple, backwards-compatible tab navigation example?
body: <p>I've spent the past 3-4 days looking for clear examples of tab navigation that would work on <code>Android</code> versions before 3.0, but every example I've gone through simply doesn't work (causes a crash) on the <code>AVD emulator</code>. In some cases these examples are extremely complicated and difficult to reproduce.</p>
  
  <p>I'm reaching out to anyone in the <code>SO</code> community who could point me towards a walkthrough for a simple Tab-based navigation system for my App. I'd like it to be backwards-compatible for <code>Android</code> versions older than 3.0.</p>
  
  <p>I'd be really grateful if anyone can simply point me towards a tutorial. I am by no means demanding anyone do this, but if someone is feeling particularly charitable the extra attention would be <em>really</em> appreciated!</p>
