Android ActionBar Tab Color

For anyone wants to change actionbar color/background in code, you can do something like this

final ActionBar actionBar = getActionBar();
actionBar.setBackgroundDrawable(getResources().getDrawable(R.drawable.action_bar_bg));

To change the tab bar color under the actionbar:

actionBar.setStackedBackgroundDrawable(new ColorDrawable(getResources().getColor(R.color.color_brown_dark)));

To change tab bar background:

actionBar.setStackedBackgroundDrawable(getResources().getDrawable(
            R.drawable.coupon_header));
