[android-developers] To play gif from a file

Hi,

I have found tutorials about how to play animated gifs in android by reading it from an asset or using a drawable object. But what I want is to read a gif file from sdcard. 

I have changed the project reading gif from assets a little bit.

In the main activity, I basically create gifMovieView then setContent(gifMovieView)

In the constructor of the GifMovieView class, I have initailized the Movie object like in the project "eu.andlabs.tutorial.animatedgifs". But I have used decodeFile giving the file path instead of decodeStream getting inputStream.

        File file = new File (Environment.getExternalStorageDirectory().getAbsolutePath(),"piggy.gif");

       

        if(file.exists()){

        

               mMovie = Movie.decodeFile(file.getPath()); 

       }

I HAVE GİVEN I/O EXCEPTION for this line. It finds the file but decodeFile gives exception.

In onDraw ;

    @Override

    protected void onDraw(Canvas canvas) {

        canvas.drawColor(Color.TRANSPARENT);

        super.onDraw(canvas);

        final long now = SystemClock.uptimeMillis();

        if (mMoviestart == 0) { 

            mMoviestart = now;

        }

        

        Log.i("",""+mMovie.duration());

        

        Log.i("",""+mMoviestart);

        

        final int relTime = (int)((now - mMoviestart) % mMovie.duration());

        mMovie.setTime(relTime);

        mMovie.draw(canvas, 10, 10);

        this.invalidate();

    }

BECAUSE OF THE EXCEPTION, movie.duration becomes 0 causing the error.

Any suggestions?

Thank you in advance
