title: Stuck with @SuppressLint("NewApi") (developer.android.com/training/basics/firstapp/starting-activity)
body: <p>I'm a begginer with Android and currently stuck with the lession: <a href="http://developer.android.com/training/basics/firstapp/starting-activity.html">http://developer.android.com/training/basics/firstapp/starting-activity.html</a></p>
  
  <p>In the part <strong>Create the Second Activity</strong>, when I try to use the code:</p>
  
  <pre><code>public class DisplayMessageActivity extends Activity {
  
      @SuppressLint("NewApi")
      @Override
      protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_display_message);
  
          // Make sure we're running on Honeycomb or higher to use ActionBar APIs
          if (Build.VERSION.SDK_INT &gt;= Build.VERSION_CODES.HONEYCOMB) {
              // Show the Up button in the action bar.
              getActionBar().setDisplayHomeAsUpEnabled(true);
          }
      }
  
      @Override
      public boolean onOptionsItemSelected(MenuItem item) {
          switch (item.getItemId()) {
          case android.R.id.home:
              NavUtils.navigateUpFromSameTask(this);
              return true;
          }
          return super.onOptionsItemSelected(item);
      }
  }
  </code></pre>
  
  <p>I get the error below:</p>
  
  <p><strong>@SuppressLint("NewApi")</strong> -> The attribute value is undefined for the annotation type SuppressLint.</p>
  
  <p>if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.<strong>HONEYCOMB</strong>) -> HONEYCOMB cannot be resolved or is not a field.</p>
  
  <p><strong>getActionBar</strong>().setDisplayHomeAsUpEnabled(true); -> The method getActionBar() is undefined for the type DisplayMessageActivity.</p>
  
  <p><strong>NavUtils</strong>.navigateUpFromSameTask(this); -> NavUtils cannot be resolved</p>
  
  <p>Someone let me know how to solve?
  Here is what I imported:</p>
  
  <pre><code>import android.app.Activity;
  import android.os.Build;
  import android.os.Bundle;
  import android.view.MenuItem;
  </code></pre>
  
  <p>Many thanks!</p>
