title: App crashes in FroYo & Gingerbread
body: <p>--The anonymous answer is my answer that I solved this issue with.--</p>
  
  <p>I have been writing an app for Android, all is working well in Honeycomb, but not playing nice on my FroYo &amp; Gingerbread devices (opposite of what you'd expect right).</p>
  
  <p>Here is the code that I believe is causing the issue:</p>
  
  <pre><code>@Override
  protected void onStart() {
      int versionNumber = Integer.valueOf(android.os.Build.VERSION.SDK);
      if (versionNumber == 11) {
          super.onStart();
          ActionBar actionBar = this.getActionBar();
          actionBar.setDisplayHomeAsUpEnabled(true);
      }
  }
  </code></pre>
  
  <p>Here I implement the ActionBar's icon-up-to-home ability, I added the versionNumber variable as I believed the lack of an ActionBar in pre-Honyecomb devices was causing the issue when the activity was run, but it still crashes and I believe this is the issue, although I am terrible with debugging and don't understand anything I am given by logcat.</p>
  
  <p>Edit: logcat - I hope I got the right section?!</p>
