Fragment getArguments() returns null

Question

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

Answer 1

I'm thinking this has to do with your problem:

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

Fragment fragment = new EpgEventListFragment();
fragment.setArguments(arguments);
fm.beginTransaction()
    .replace(placeholder, fragment, tabId)
    .commit();
