Handle end of animation for AnimationDrawable

I have a old exercise "Create frame animation with AnimationDrawable", which play animation repeatly without handle end of the animation. In this exercise, I will do something when the animation end.

AnimationDrawable have no any Listener for the end of animation, and also I cannot use the isRunning() method to determine the end of animation. Finally, I calculate the total duration of the animation using its getNumberOfFrames() and getDuration(). And then use Timer and TimerTask to schedule a Runnable() run when the time reached.

First of all, modify /res/anim/anim_android.xml to set android:oneshot="true", re-use the layout, main.xml, and the frame pictures. All of them can be found here.

Main code:
package com.exercise.AndroidAnimation;

import java.util.Timer;
import java.util.TimerTask;

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

public class AndroidAnimationActivity extends Activity {

AnimationDrawable myAnimationDrawable;

Timer timer;
MyTimerTask myTimerTask;

public void onCreate(Bundle savedInstanceState) {

ImageView myAnimation = (ImageView)findViewById(R.id.myanimation);
= (AnimationDrawable)myAnimation.getDrawable();

new Runnable(){

public void run() {

//Calculate the total duration
int duration = 0;
for(int i = 0; i < myAnimationDrawable.getNumberOfFrames(); i++){
duration += myAnimationDrawable.getDuration(i);

timer = new Timer();
myTimerTask = new MyTimerTask();
timer.schedule(myTimerTask, duration);

class MyTimerTask extends TimerTask {

public void run() {

runOnUiThread(new Runnable(){
public void run() {
"Animation Stopped",
