Why Animation is speed up after first run?
<p>In my activity i am playing animations.. When i am starting the activity for first time,all the animations are playing with the given duration. But it is speed up when i am repeating  each and every animation for more time.. This is my activity.... And In my code i haven't provide all object and variable declaration to reduce the code...</p>

<p>public class Exercise extends Activity {
    /** Called when the activity is first created. */</p>
