Add Fragments dynamically to ViewPager

code implementation

List<Fragment> fragments = buildFragments();
ArrayList<String> categories = {"1", "2", "3", ..., "n"};
mPager = (ViewPager) v.findViewById(R.id.pager);
mPageAdapter = new MyFragmentPageAdapter(this,getSupportFragmentManager(), fragments, categories);
mPager.setAdapter(mPageAdapter);

//Add a new Fragment to the list with bundle
Bundle b = new Bundle();
b.putInt("position", i);
String title = "asd";
mPageAdapter.add(MyFragment.class, title, b);
mPageAdapter.notifyDataSetChanged();

FragmentPageAdapter

import android.content.Context;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;

public class MyFragmentPageAdapter extends FragmentPagerAdapter {

	public static int pos = 0;

	private List<Fragment> myFragments;

Fragments list builder

private List<android.support.v4.app.Fragment> buildFragments() {
		List<android.support.v4.app.Fragment> fragments = new ArrayList<android.support.v4.app.Fragment>();
		for(int i = 0; i<categories.size(); i++) {
			Bundle b = new Bundle();
			b.putInt("position", i);
			fragments.add(Fragment.instantiate(this,MyPagerFragment.class.getName(),b));
		}

		return fragments;
	}
