This is my first java and first Android project. Your tutorials have been extremely helpful, thank you. I want to modify your Android Pong game to become a clock with floating digits. I removed the Bat class & its references. The ball played by itself just fine. I increased the size of the Ball. (I plan to draw time digits on the ball rectangle later.)

The problem: the larger ball (mBallWidth = screenX / 30;) gets stuck on the left wall the first time it hits it. I don’t understand why. The xVelocity does get reversed but the ball is half off the left side, even though the left x of ball is positive. It travels up and down but never leaves the left side. Would you please help? I would appreciate even a hint on what is going on.

Thank you.

There were two problems in addition to the one already mentioned. One bug is with the update method which uses mFPS, but is not ready at the first time it is called before it is actually calculated.
The second is just a visual bug which causes the ball bounce right and left when it is hitting the edge in a sharp angle. I fixed these, that was a good test to see if I understand the subject.
