Navigation drawer not working in android lollipop

Question

I have in my project Android Design Library and I'm working with navigation view but I have an issue with it. From API 15 till 20 everything is working fine as suppose to work but when I tried on API 21 (5.0) and higher it's not working even it's not showing the hamburger button. And I can't find where is the problem. Does anyone faced with similar problem? I'm working in xamarin with C#. This is the code:

using Android.App;
using Android.Widget;
using Android.OS;
using Android.Support.V4.Widget;
using Android.Support.V7.App;
using Android.Support.Design.Widget;
using System.Collections.Generic;
using System.Threading.Tasks;
using System;
using Android.Content;
using Android.Views;
using Android.Webkit;

If someone face in future with similar problem this was solution for my problem. As I guessed problem wasn't in code. I added design library via components but that is not the latest version and you will face with errors in android lollipop or higher so add it via NuGet Packages or make an update and you will get the latest version.
