title: New to Android development and while following tutorial by teamtreehouse, I keep getting errors
body: <p><a href="http://teamtreehouse.com/library/build-a-simple-android-app/getting-started-with-android/android-setup-and-the-crystal-ball-project-2" rel="nofollow">tutorial link</a></p>
  
  <p>So I pick from apk 8 through current one kitkat.</p>
  
  <p>I create application/project,</p>
  
  <pre><code>The import android.support.v7.app.ActionBar is never used.
  The import android.os.Build is never used.
  </code></pre>
  
  <p>and then I get the above errors from the MainActivity.java file regarding these two lines:</p>
  
  <pre><code>import android.support.v7.app.ActionBar;
  import android.os.Build;
  </code></pre>
  
  <p>And the graphical view of <code>activity_main.xml</code> shows no "Hello world!" text, and it sends me to the <code>fragment_main.xml</code> where the "Hello world!" text is on the top left.</p>
  
  <p>I'm pretty sure the tutorial I'm following is a bit outdated since it didn't show fragment xml and kitkat version. So was this all normal?</p>
