title: Navigate Up with Actionbar Compat
body: <p>Following developers guide to set the app icon as up button, I done these steps to achieve this:</p>
  
  <p>In the Activity:</p>
  
  <pre><code>protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.configuration);
  
      /**Enable app icon as Up button on ActionBar*/
      ActionBar actionBar = getSupportActionBar();
      actionBar.setDisplayHomeAsUpEnabled(true);
  </code></pre>
  
  <p>In the Manifest:</p>
  
  <pre><code>&lt;activity 
      android:name="com.example.Configuration"
      android:label="@string/config_title"          
      android:parentActivityName="com.example.MainActivity" &gt;
          &lt;!-- Parent activity meta-data to support API level 7+ --&gt;
          &lt;meta-data
              android:name="android.support.PARENT_ACTIVITY"
              android:value="com.example.MainActivity" /&gt;
  &lt;/activity&gt;
  </code></pre>
  
  <p>But still doesn't make the up function.</p>
