Using in this

• TouchEvents
• MVC

Please modify the Android AnimationExample (provided) byimplementing a paddle that reflects the ball when it hits it. Youshould use the touch event to control the movement of the paddle.In addition, you can try to use the accelerometer to control themovement of the paddle for possible extra-credit.The assignmentexample classes are is below.

AnimationView.java

You should use the touch event to control the movemert of the paddle. In aclcition, you con try to use the accelerometer to control the movement of the paddle for possible extra-credit Files to Upload for this Lab: Lab07 zip The source code must be indented properly and cortain comments that descrbe important perts of the aigorthm. The use of proper Indentation is considered good programming style, and you are expected to use good programming style. Make sure that you upload your program to Moodie’s drop-box when you are done in order to receive credt for this lab.
