Android device is not showing the background image

I have created a project, targeting android 4.4 - API Level 19, as suggested by eclipse.

Anyways, on the emulator everything looks perfect - here is a screenshot:

The problems comes when I install it on my real device - running android 4.1.2. Everything is just perfect and working like a charm, excepting the background image. It is showing a white background, like the picture does not exists.

Here is my xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" 
    android:orientation="vertical"
    android:gravity="center"
    android:padding="30dp"
    android:background="@drawable/wg_blurred_backgrounds_12"
>

<Button
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/btnTopJokes" 
    android:onClick="showTopJokes"   
    android:gravity="center" 
/>

<Button
    android:layout_marginTop="10dp"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/btnNewJokes" 
    android:onClick="showNewJokes" 
    android:gravity="center"
/>

<Button
    android:layout_marginTop="10dp"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/btnAllJokes" 
    android:onClick="showAllJokes" 
    android:gravity="center"
/>

<Button
    android:layout_marginTop="10dp"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/btnMyFavorites" 
    android:onClick="showFavorites" 
    android:gravity="center"
/>

<Button
    android:layout_marginTop="10dp"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/btnCategories" 
    android:onClick="showCategories"
    android:gravity="center"
/>

<Button
    android:layout_marginTop="10dp"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/btnAddNewJoke" 
    android:gravity="center"
/>

</LinearLayout>

Isn't android:background="@drawable/wg_blurred_backgrounds_12 working on android 4.1.2 ?

Do I have to change anything in the premissions? Here is what I have now:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

I know that I miss something really small, but I'm not able to spot it as a beginner.

You can also try to disable hardware acceleration to the view you are setting background

myView.setLayerType(View.LAYER_TYPE_SOFTWARE, null)

and then set the background

Make sure it doesn't say (24) or (v 24) next to the image file you have in your drawable file, re-copy the image and make it save it as the type with no (24) in it as it will prepare it to be used for API 24 and above, my phone uses that's why it failed on my part API 23.

you may need to add this to your manifest file . android:hardwareAccelerated="false" , android:largeHeap="true"

 <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/logo"
        android:supportsRtl="true"
        android:hardwareAccelerated="false"
        android:largeHeap="true"
        android:theme="@style/AppTheme">
