@elluminati10 you need to use ActionbarSherlock to use this feature.

abs_home is part of ActionbarShrelock lib : https://github.com/JakeWharton/ActionBarSherlock/search?utf8=%E2%9C%93&q=abs__home

Add following line to your gradle of DobSliding module - if you are using android studio, else download the lib from officials http://actionbarsherlock.com/download.html

compile 'com.actionbarsherlock:actionbarsherlock:4.4.0@aar'

else download the lib from officials http://actionbarsherlock.com/download.html

Some facts about ActionbarSherlock
JakeWharton/ActionBarSherlock#38

The point is while you use TabActivity and child activity inside Tabhost, you will face the same issue once you call ((TabActivity) getParent()).getActionBar().set...() in your childActivity Extends Activity and then try to create object of

    // Initialization
    try {
        // Instance of this activity as a parameter
        vSlidingMenu = new DobSlidingMenu(this);

        // Sliding type can be sizing or moving
        vSlidingMenu.setSlidingType(SlidingType.SIZE);

   ..}

if you just use getActionBar().set...() ... then the null pointer error will lies here for any method call using getActionBar() ... before you can create object of DobSlidingMenu
