Answer 1

I´ve found a lot of answers here @ stackoverflow.com but definitely this is the correct answer of:

"Sending data from activity to fragment in android".

Activity:

        Bundle bundle = new Bundle();
        String myMessage = "Stackoverflow is cool!";
        bundle.putString("message", myMessage );
        FragmentClass fragInfo = new FragmentClass();
        fragInfo.setArguments(bundle);
        transaction.replace(R.id.fragment_single, fragInfo);
        transaction.commit();

Fragment:

Reading the value in the fragment

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        Bundle bundle = this.getArguments();
        String myValue = bundle.getString("message");
        ...
        ...
        ...
        }

or just

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        String myValue = this.getArguments().getString("message");
        ...
        ...
        ...
        }

Answer 2

My solution is to write a static method inside the fragment:

public TheFragment setData(TheData data) {
    TheFragment tf = new TheFragment();
    tf.data = data;
    return tf;
}

This way I am sure that all the data I need is inside the Fragment before any other possible operation which could need to work with it. Also it looks cleaner in my opinion.
