There is no expand animation when clicked on the last item on KitKat

[dzolnai]

When expanding the last group on Android 4.4, there is no expand animation, the group is opened instantly. The collapse animation for the same group works fine.
Possibly on Ice Cream Sandwich too, because removing the following lines from the expandGroupWithAnimation(int groupPos) method in AnimatedListViewExample.java makes it work again:

boolean lastGroup = groupPos == adapter.getGroupCount() - 1;
if (lastGroup && Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH) {
    return expandGroup(groupPos, true);
}

+1 to this. Why is the expand animation disabled for 14+, did it cause problems in a specific android version?

+1, I want to know why you disabled the animation of last group.

This commit message makes me think it's a simple mistake and condition should be other way around.

Seems you are right. Testing on Lollipop, I changed to this condition at the beginning of expandGroupWithAnimation():

if (lastGroup && Build.VERSION.SDK_INT < Build.VERSION_CODES.ICE_CREAM_SANDWICH) {
    return expandGroup(groupPos, true);
}

I shield these codes and everything is OK. I have tested in android 2.3, android 4.4 and android 5.1.

+1, I am testing in my tablet ME173X (JellyBean) and seems that the animation works for API level 17 too.

When you include a footer view. The last group stop responding to listener. You click and nothing happens. Lollipop version works fine but in Jelly Beans it doesn't.
