title: Android getActionBar vs getSupportActionBar?
body: <p>Here is my code:</p>
  <pre><code>if (Build.VERSION.SDK_INT &gt;= Build.VERSION_CODES.HONEYCOMB){
  
      //android.support.v7.app.ActionBar actionBar = getSupportActionBar();
      //actionBar.setTitle(&quot;Android&quot;);
  
      ActionBar actionBar = getActionBar();
      actionBar.setTitle(&quot;Droid&quot;);
  }
  </code></pre>
  <p>While using the getSupportActionBar() my app runs just fine with kitkat and other new versions but using getActionBar results into an error.</p>
  <p>Here is error:</p>
  <pre><code>Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'void android.app.ActionBar.hide()' on a null object reference

  <p>Why? From android documentations :</p>
  <blockquote>
  <p>Caution: Be certain you import the ActionBar class (and related APIs)
  from the appropriate package:</p>
  <p>If supporting API levels lower than 11:
  import android.support.v7.app.ActionBar</p>
  <p>If supporting only API level
  11 and higher:  import android.app.ActionBar</p>
  </blockquote>
  <p>Now why this app is crashing?</p>
