[android-developers] Re: To play gif from a file

No problem.

Also, what you may want to do is simply use the *GifDecoderView* class that 
is also in that project:


*FileInputStream fis = null;*
*try {*
* fis = new FileInputStream("/mnt/sdcard/piggy.gif");*
*} catch (FileNotFoundException e) {*
* **e.printStackTrace();*
*}*
*
*
*GifDecoderView view = new GifDecoderView(this, fis);*
*
*
*setContentView(view);*

It seems to work well.


Thanks.

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(10);*
*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.

I have looked further into this issue, and the issue is actually a bug in 
FileInputStream.  Basically, every class that derives from InputStream 
needs to implement the reset() method, and FileInputStream neglects to do 
so.  


Please see this in the InputStream source code:






Thanks.

I have played animated GIFs on Android before simply by loading them in a *
WebView*.


Thanks.
