Toolbar disappears when using Vuforia versions below 4.4

问题

I am using the SDK Vuforia and testing on devices with version 4.4 below the toolbar disappears, the menu buttons are there but invisible where would be the correct buttons are visible. The drawerlayout button with recyclerview I use the side menu does not work in version below 4.4, and its icon disappears. With much effort can swipe to activate the side menu. Above this version of the menu functions and buttons are displayed. The following images and correct the problem and xml layouts.

camera_overlay.xml

    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent"
android:layout_height="match_parent">

<LinearLayout

    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:layout_centerInParent="true">

    <ImageView
        android:id="@+id/ivLoading"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
