Background drawable in RelativeLayout is not showed on Android 5.1.1

Question

I have added a drawable as a background to a RelativeLayout object (drawable with bitmap). This is my code:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                xmlns:tools="http://schemas.android.com/tools"
                xmlns:fbutton="http://schemas.android.com/apk/res-auto"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:paddingLeft="@dimen/activity_horizontal_margin"
                android:paddingRight="@dimen/activity_horizontal_margin"
                android:paddingTop="@dimen/activity_vertical_margin"
                android:paddingBottom="@dimen/activity_vertical_margin"
                tools:context=".MainActivity"
                android:id="@+id/FirstSlideFrame"
                android:background="@drawable/background_darken">
</RelativeLayout>

and background_darken.xml(the drawable):

<?xml version="1.0" encoding="utf-8"?>
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
        android:src="@drawable/new_bg"
        android:gravity="center_horizontal"/>

It works fine on Android 2.2, 2.3, 4.2.2 but on Android 5.1.1 the image is not showed.

Any Idea how to fix it?

Thanks

EDIT (blurred some parts...):

4.2.2 5.1.1

Updated activity_main.xml:

    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    </RelativeLayout>

Basically BitmapDrawable is deprecated from API level 18. If you see this. Its not advisable to use it. So that it will have different behaviour in latest os versions.
