As a workaround, you can probably do something like this:
*FileInputStream fis = new FileInputStream("/mnt/sdcard/piggy.gif");*
*BufferedInputStream bis = new BufferedInputStream(fis);*
*bis.mark(100000);*
*Movie movie = Movie.decodeStream(bis);*
*int width = movie.width();*
*int height = movie.height();*
*Log.d("gif", "width = " + width + ", height = " + height);*
Basically, you need to create an InputStream where reset() works (or at
least doesn't throw an Exception).
For me, the code correctly showed the width and height of the GIF to be
85x85.
Thanks.
