How to create transitionset

Ordering_Sequentional constant not found.. Fade class also not found, how Can I create transitionSet

MainActivity.java 
public class MainActivity extends Activity {

    protected TransitionManager mTransitionManager;
    protected Scene mScene1;
    protected Scene mScene2;
    protected Scene mCurrentScene;
    protected TransitionSet mForwardSet;
    protected TransitionSet mBackwardSet;

    // Some code omitted for brevity

    public void onButtonClicked(View view) {
        if (mCurrentScene == mScene2) {
            mCurrentScene = mScene1;
        }
        else {
            mCurrentScene = mScene2;
        }

      mTransitionManager.transitionTo(mCurrentScene);

    }

    protected void setupTransitions() {
        // These methods are setting up scenes and transitions sets like in the video


      mTransitionManager = new TransitionManager();

      TransitionSet forwordSet = new TransitionSet();
      TransitionSet backwordSet = new TransitionSet();
      forwordSet.setOrdering(TransitionSet.ORDERING_SEQUENTIAL);
      backwordSet.setOrdering(TransitionSet.ORDERING_SEQUENTIAL);

      mTransitionManager.setTransition(mScene1, mScene2, forwordSet);
        mTransitionManager.setTransition(mScene2, mScene1, backwordSet);
      mScene2.enter();
        initScenes();
        initSets(); 

        // Start here!

    }
}

    protected void setupTransitions() {
        // These methods are setting up scenes and transitions sets like in the video
        initScenes();  // <--- restore these two calls. you inadvertently removed them
        initSets(); 

        // Start here!
        mTransitionManager = new TransitionManager();

        // No need to set up the TransitionSets since the init methods take care of those.
        // Just set the two transitions asked for in the question.
        mTransitionManager.setTransition(mScene1, mScene2, mForwardSet);
        mTransitionManager.setTransition(mScene2, mScene1, mBackwardSet);        
    }
