Clear backstack

[parassftpl]

I have a button in my Activity. On click of button, I want to clear whole backstack and keep my home fragment.

How do I do that?

List<IMasterFragment> fragments =  getFragmentMaster().getFragments();
for(int i = fragments.size() - 1; i > 0; i--) {
    fragments.get(i).finish();
}
