Answer 1

This can happen when try to add the same fragment more than once.

    public void populateFragments() {
        Fragment fragment = new Fragment();
        //fragment is added for the first time
        addFragment(fragment);

        // fragment is added for the second time
        // This call will be responsible for the issue. The 
        addFragment(fragment);
    }

    public void addFragment(Fragment fragment) {
        FrameLayout frameLayout = AppView.createFrameLayout(context);
        view.addView(frameLayout);
        getSupportFragmentManager().beginTransaction().add(frameLayout.getId(), fragment).commit();
    }
