Stuck on code challenge! Please help I watched the video a billion times and I still cant get it!

I am stuck on task 2 of 4 in the "Animating the Crystal Ball" code challenge. Here is the code I thought would work for this code challenge(2 of 4).

package com.example;

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

public class MainActivity extends Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}
public void animateFrog() {
    ImageView frogImage = (ImageView) findViewById(R.id.frog);
AnimationDrawable jumpAnimation = (AnimationDrawable) frogImage.getDrawable();
if (jumpAnimation.isRunning()) {
  jumpAnimation.stop();
}
jumpAnimation.start();

}

If anyone can help please help!
