Hey Patrick. Thanks for such a detailed tutorial. It helps me a lot!

Just a little note here. In item_animation_fall_down.xml and other animation xml files you posted, the duration part (android:duration=”@integer/anim_duration_medium”) doesn’t seem to work for me, but (android:duration=”@android:integer/config_mediumAnimTime”) this one does.

Hope this one helps others having the same problem.
