As the .Gif file contains the duration of each frame, my little script has been modified because the duration parameter is not needed.
Name of class and view parameter are also modified because the view in which the gif will be displayed may be any View, not only an ImageView.
I also remove the touch_ended method because it is not needed here.
Sorry for these modifications, I had posted too quickly, just to be sure I'd not forget, I've a so bad memory 😢
