Xamarin Forms - Change Android Toolbar height

Hey guys ,

I have never been able to find a solution for this issues and wondering if anyone know how to change the navbar height for Android in Xamarin Forms -

I added this but made no difference : android:layout_height="30dp"

This is my Toolbar.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="30dp"
android:background="?attr/colorPrimary"
android:popupTheme="@style/ThemeOverlay.AppCompat.Light"
app:titleTextAppearance="@style/Toolbar.TitleText"
app:layout_scrollFlags="scroll|enterAlways" />
