 Pair[] pairs = new Pair[1];
            pairs[0] = new Pair<View, String>(tvArtifacts, "itemTrans");
            ActivityOptions options = null;
            if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP) {
                options = ActivityOptions.makeSceneTransitionAnimation(getActivity(), pairs);
            }

            Intent i = new Intent(getActivity(), ItemDetailActivity.class);
            i.putExtra("item_name", "item 2");
            if (options != null) {
                startActivity(i, options.toBundle());
            } else {
                startActivity(i);
            }

This worked for me! Thanks..

I finally found the answer, the startActivity calling method is different. You have to call

startActivityFromFragment(fragment, intent, req_code, options.toBundle());

I had the same problem, I couldn't find anything that helps sorry, but maybe you should reconsider why would you need a Fragment to Activity relation when you could work with a Fragment to Fragment or Activity to Activity relation.

I've solved my problem that way changing my code to a Fragment to Fragment relation and there is plenty documentation and examples about that Shared Element Transitions
