No resource found that matches the given name (at 'headerLayout') in Xamarin.Android

Question

I'm creating Android app using Xamarin for Android. I want to use in my app NavigationDrawer, so I downloaded and installed 'Android Design Library' from Xamarin Components Store. Then I edited my layout for this:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/drawerLayout"
    android:layout_height="match_parent"
    android:layout_width="match_parent"
    android:fitsSystemWindows="true">

    <include
        android:id="@+id/toolbar"
        layout="@layout/toolbar" />
    <ListView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/articlesListView" />
    <android.support.design.widget.NavigationView
        android:id="@+id/navView"
        android:layout_height="match_parent"
        android:layout_width="wrap_content"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/navHeader"
        app:menu="@menu/navMenu"/>
</android.support.v4.widget.DrawerLayout>

navHeader.axml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="192dp"
    android:background="?attr/colorPrimaryDark"
    android:padding="16dp"
    android:theme="@style/ThemeOverlay.AppCompat.Dark"
    android:orientation="vertical"
    android:gravity="bottom">

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Username"
        android:textAppearance="@style/TextAppearance.AppCompat.Body1"/>

</LinearLayout>

and menu/navMenu.xml:

<?xml version="1.0" encoding="UTF-8" ?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
  <group android:checkableBehavior="single">
    <item
      android:id="@+id/nav_home"
      android:title="Home" />
    <item
      android:id="@+id/nav_messages"
      android:title="Messages" />
    <item
      android:id="@+id/nav_friends"
      android:title="Friends" />
    <item
      android:id="@+id/nav_discussion"
      android:title="Discussion" />
  </group>
  <item android:title="Sub items">
    <menu>
      <item
        android:title="Sub item 1" />
      <item
        android:title="Sub item 2" />
     </menu>
  </item>
</menu>

Unfortunately while compiling, I received following error:

C:\Project\Project\File.axml: Error APT0000: No resource found that matches the given name (at 'headerLayout' with value '@layout/navHeader'). (APT0000) (AppName) C:\Projects\Project\File.axml(0,0): Error APT0000: No resource found that matches the given name (at 'menu' with value '@menu/navMenu'). (APT0000) (AppName)

Somebody knows how I may solved this problem?

Thank you in advance

I had the same issue. I simply put lower case letters in the name of the header layout file and it worked.

Before (Failing with same error message):

app:headerLayout="@layout/DrawerHeader"

After:

app:headerLayout="@layout/drawerheader"
