Java.lang.NoClassDefFoundError: fragment

I am learning the Android Sliding Menu using the navigation box http://www.androidhive.info/2013/11/android-sliding-menu-using-navigation-drawer/ . This tutorial, sample code works in Android 3.0 or Honeycomb. I want it to work on android 2.3.3. Then I completed this tutorial http://hmkcode.com/add-actionbar-to-android-2-3-x/ . Here is what I did:

  • I changed the "Activity" to "ActionBarActivity".
  • Then change "gettActionBar ()" to "getSupportActionBar ().
  • Sets the style on the manifest to "@ style / Theme.AppCompat.Light
  • Well, the addition of android v.7 support for Compabiltiy.
