<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">
    <item
        android:id="@+id/action_movies"
        android:enabled="true"
        android:icon="@drawable/ic_local_movies_black_24dp"
