set android animation list programmatically

Question

I am trying to achieve adding the animated gifs into my application.

1- I am able to download the animated gif from server. 2- I am able to decode the animated gif (using my custom decoder) and have a separate Bitmap corresponding to its frames.

Now I want to animate it using the frame by frame animation. As i read, to perform the frame by frame animation the first thing that is required is "animation-list".

I want to know how i can create the required "animation-list" programatically containing each Bitmap as a separate frame.

You can use AnimationDrawable similiar to http://androidforums.com/application-development/11620-programmatic-frame-frame-animation-examle-animationdrawable.html but use your own files instead of taken from resources.

Note that you have to be careful about density of screen and bitmaps which are downloaded rather than taken from resources otherwise it might look differently on different screen sizes/resolutions.
