enter ripple animation play twice.

[lucca2011]

Long press and release finger before ripple animation ended, the enter animation will play twice.
In Ripple.java method enter(), called animation start twice here.
Comment the three line may fix it.
// radius.start();
// cX.start();
// cY.start();

    AnimatorsCompat.startWithAutoCancel(radius);
    AnimatorsCompat.startWithAutoCancel(cX);
    AnimatorsCompat.startWithAutoCancel(cY);
