Animation Drawable not working in GingerBread

Question

This question is already been asked,but i didn't find any suitable answers and so I'm posting the question. I've a ProgressBar animation which has multiple images and loads these images like a progressbar. I'm able to run it successfully in 4.0 and higher versions but it doesn't work in 2.3.How to make it work in lower versions?

My Animation Drawable XML file

<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android"
    android:oneshot="false"
    android:pivotX="50%"
    android:pivotY="50%" >
    <item android:drawable="@drawable/p1_wheel" android:duration="200"/>
    <item android:drawable="@drawable/p2_wheel" android:duration="200"/>
    <item android:drawable="@drawable/p3_wheel" android:duration="200"/>
    <item android:drawable="@drawable/p4_wheel" android:duration="200"/>
    <item android:drawable="@drawable/p5_wheel" android:duration="200"/>
    <item android:drawable="@drawable/p6_wheel" android:duration="200"/>
    <item android:drawable="@drawable/p7_wheel" android:duration="200"/>
    <item android:drawable="@drawable/p8_wheel" android:duration="200"/>
    <item android:drawable="@drawable/p9_wheel" android:duration="200"/>
    <item android:drawable="@drawable/p10_wheel" android:duration="200"/>
    <item android:drawable="@drawable/p11_wheel" android:duration="200"/>
    <item android:drawable="@drawable/p12_wheel" android:duration="200"/>
</animation-list>

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        progressbar = (ImageView) findViewById(R.id.imageView1);
        progressbar.setBackgroundResource(R.drawable.progressbar);
        final AnimationDrawable frame = (AnimationDrawable) progressbar.getBackground();
        progressbar.post(new Runnable() {

            @Override
            public void run() {
                frame.start();
            }
        });
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

}

At Last I found a solution to this.

 progressbar = (ImageView) findViewById(R.id.imageView1);
 progressbar.setBackgroundResource(R.drawable.progressbar);
 final AnimationDrawable frame = (AnimationDrawable)getResources.getDrawable(R.drawable.progressbar);  \\progressbar is the anim.xml file
 progressbar.setBackgroundDrawable(frame);
 progressbar.post(new Runnable() {

            @Override
            public void run() {
                frame.start();
            }
        });
    }
