Android Jpg Animation

I would like to download 10 JPG pictures from a site. The pictures where taken at intervals >> that is no problem How do I save pictures in an array of pictures. How would I

Solution 1:

You'll probably want to use AnimationDrawable in an ImageView.

Add frames using the addFrame(Drawable frame, int duration) method, and start the animation using start().

You can use many different methods to download and store the image (perhaps to external storage, or a db).

Solution 2:

I have an example of this, here I am downloading three images form site and then store in it path "/mnt/sdcard/..". If you want to show this in animation then I think that you can use flipper and then add this image dynamically and using an async task you can flip image next.
