Best practice: Extending or overriding an Android library project class

Question

We\'re using an Android Library Project to share core classes and resources across different builds (targets) of our Android application. The Android projects for each speci

I was inspired by PoinsoneR's answer to create a Utility class to do the same thing for Fragments - override a fragment in an android Library. The steps are similar to his answer so I won't go into great detail, but here is the class:

package com.mysweetapp.utilities;

import android.support.v4.app.Fragment;

public class FragmentUtilities 
{
    private static Class getFragmentClass(Class clazz) 
    {
        // Check for extended fragment
        String extClassName = clazz.getName() + "Extended";
        try 
        {
            Class extClass = Class.forName(extClassName);
            return extClass;
        } 
        catch (ClassNotFoundException e) 
        {
            e.printStackTrace();
            // Extended class is not found return base
            return clazz;
        }
    }

    public static Fragment getFragment(Class clazz) 
    {
        Class fragmentClass = getFragmentClass(clazz);

        Fragment toRet = null;

        try 
        {
            toRet = (Fragment)fragmentClass.newInstance();

            return toRet;
        } 
        catch (InstantiationException e) 
        {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } 
        catch (IllegalAccessException e) 
        {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        return toRet;
    }
}

Usage:

FragmentUtilities.getFragment(MySpecialFragment.class)
