Establecer animado .GIF como fondo Android

Soy nuevo en Android y tengo problemas para reproducir un archivo .gif animado en el fondo de mi diseño. Cuando ejecuto la aplicación, el fondo es un solo cuadro del .gif animado, como una imagen. He investigado principalmente en dos áreas:

El siguiente enlace es donde obtuve la mayor ayuda.

Android OS comenzando BlogSpot

El siguiente enlace me hace pensar que los errores que estoy recibiendo tienen algo que ver con que las clases se configuren como privadas, públicas o protegidas.

Foros de java

He creado la lista de animaciones = res / drawable-hdpi / progress_animation.xml

<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/selected" android:oneshot="false">
<item android:drawable="@drawable/frame02" android:duration="50" />
<item android:drawable="@drawable/frame03" android:duration="50" />
<item android:drawable="@drawable/frame04" android:duration="50" />
<item android:drawable="@drawable/frame05" android:duration="50" />
<item android:drawable="@drawable/frame06" android:duration="50" />
<item android:drawable="@drawable/frame07" android:duration="50" />
<item android:drawable="@drawable/frame08" android:duration="50" />

<item android:drawable="@drawable/frame10" android:duration="50" />
.........................................
<item android:drawable="@drawable/frame57" android:duration="50" />
<item android:drawable="@drawable/frame58" android:duration="50" />
</animation-list>

.

.

He creado un archivo de diseño para alojar la Vista de imagen = res / layout / activity_main.xml

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

<ImageView android:id="@+id/swing_play" android:layout_width="fill_parent"
    android:layout_height="wrap_content" />

</RelativeLayout>

.

Actividad de clase Java para llamar a ImageView y AnimationDrawable = com.example.apptwo / MainActivity.java

.

package com.exampleone.apptwo;

import android.os.Bundle;
import android.app.Activity;
import android.graphics.drawable.AnimationDrawable;
import android.view.Menu;
import android.widget.ImageView;

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.acivity_main);
    ImageView img = (ImageView)findViewById(R.id.swing_play);
    img.setBackgroundResource(R.drawable.progress_animation);

    AnimationDrawable frameAnimation = (AnimationDrawable) img.getBackground();

    frameAnimation.start();
}

}

.

El IDE no marca ningún error en el código. Sin embargo, cuando ejecuto la aplicación, mi emulador muestra un fondo blanco con el mensaje "Desafortunadamente, la aplicación se ha detenido."

El ErrorLog lee = "Excepción de bucle de evento no manejado"
