How to avoid recreation of Fragment inside getItem method of FragmentStatePagerAdapter

Question

I am using ViewPager and i am creating Fragments dynamically inside getItem method of FragmentStatePagerAdapter as follows and i want to avoid recreation of Fragment inside this method so that the application does not crash.

        @Override
    public Fragment getItem(int position) {
        // getItem is called to instantiate the fragment for the given page.

        Fragment fragment = new Fragment();

        switch (position) {
        case 0:                 
            fragment = new CourseOverViewFragment();
            break;
        case 1:
            fragment = new CourseSchedueListFragment();
            break;
        case 2:
            fragment = new CourseSchedueListFragment();
            break;
        case 3: 
            fragment = new CourseNoteListFragment();
            break;
        case 4:             
            fragment = new ProjectListFragment();
            break;
        default:
            Log.i(StudyManagerDataSource.LOG_TAG, "default");
            break;

        }

        return fragment;

    }
