Fragment Getarguments() Returns Null

I have a Fragment which has a TabHost as the root layout as follows...

fm.beginTransaction()
    .replace(placeholder, new EpgEventListFragment(), tabId)
    .commit();

You're making a new Fragment (that doesn't have arguments since it's been freshly instantiated).

Instead try

Fragmentfragment=newEpgEventListFragment();
fragment.setArguments(arguments);
fm.beginTransaction()
    .replace(placeholder, fragment, tabId)
    .commit();
