活动之间的过渡动画不会显示

I'm using this to override the transiting animation between two activities. At first it worked properly but now, the animation won't be displayed, though it was a problem with current project so I started a new one and the same thing happens. Is this a thing caused by my device? it is a samsung galaxy S advance with 2.3.6 android. Thank you in advanceI'm using this to override the transiting anima
