Open fragment FROM fragment, with a circular reveal. The key thing is using getChildFragmentManager, introduced in Android 4.2

QSModePicker.java

        long TRANS_DURATION = 300;

        Log.d(TAG, "Ready to reveal mode picker");

        ModeSelectorActivityFragment f = new ModeSelectorActivityFragment();

        fragmentContainer.setVisibility(View.INVISIBLE);
        getChildFragmentManager()
                .beginTransaction()
                .add(R.id.mode_list_fragment_container, f)
                .commit();

        int finalRadius = Math.max(fragmentContainer.getHeight(), fragmentContainer.getWidth());
        Animator anim = ViewAnimationUtils.createCircularReveal(fragmentContainer, (int) touchX, (int) touchY, 0, finalRadius);
        anim.setDuration(TRANS_DURATION);
        anim.setInterpolator(new AccelerateDecelerateInterpolator());
        fragmentContainer.setVisibility(View.VISIBLE);
        anim.start();
