I don't understand this code challenge?

You need to animate an image (named imageView) so that it scales up to twice its size when it is tapped. Start by simple calling the animate() method of the image.

CodeChallenge.java 
// Use the variable named 'imageView'

Hi Jarvis,

I appreciate you asking me this question, but I honestly do not know as I haven not worked with Android in more than a year. I did a Google search and found some resources that I believe may help you, if not with the challenge, with your endeavors using Android:

This worked for me :)

imageView.animate();

2/3

imageView.animate().scaleX(2).scaleY(2);

3/3

imageView.animate().scaleX(2).scaleY(2).start();

Hi Royce Foo Wai kit what they meant by "calling the animate method" is to use the variable with the method. Like this " imageView.animate();"

Hope I was able to help you start!
