Android: SkImageDecoder:: Factory returned null

I'm using my localhost to fetch images and to view in an ImageView. For some reason I'm getting Factory returned null error. I've looked through the code many times and I don't see what's wrong. Any help would be appreciated!

GalleryZoom.java

public class Zoom extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.gallery_zoom);

        String selection = getIntent().getExtras().getString("image");
        Toast.makeText(this, selection, Toast.LENGTH_LONG).show();

        new backgroundLoader().execute();       
    }


    private class backgroundLoader extends AsyncTask<Void, Void, Void> {
        Bitmap bmp;

        @Override
        protected Void doInBackground(Void... params) {

            bmp = DecodeBitmapSampleSize(getIntent().getExtras().getString("image"), 48, 64);
            return null;
        }

        @Override
        protected void onPostExecute(Void result) {
            super.onPostExecute(result);

            ImageView image = (ImageView) findViewById(R.id.imageZoom);
            image.setImageBitmap(bmp);
        }

    }

    public Bitmap DecodeBitmapSampleSize (String strURL, int reqWidth, int reqHeight) {
        InputStream in = null;
        Bitmap bmp = null;

        in = OpenHttpConnection(strURL);
        final BitmapFactory.Options options = new BitmapFactory.Options();
        options.inJustDecodeBounds = true;
        BitmapFactory.decodeStream(in, null, options);

        options.inSampleSize = calculateSampleSize(options, reqWidth, reqHeight);

        options.inJustDecodeBounds = false;
        bmp = BitmapFactory.decodeStream(in, null, options);
                return bmp;
    }

    private InputStream OpenHttpConnection(String strURL) {

        try {
            URL url = new URL(strURL);

            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            InputStream in = new BufferedInputStream(connection.getInputStream());
            return in;
        } catch (Exception exception) {
            exception.printStackTrace();
            return null;
        }
    }

    public static int calculateSampleSize(BitmapFactory.Options options,
            int reqWidth, int reqHeight) {

        final int width = options.outWidth;
        final int height = options.outHeight;
        int inSampleSize = 1;

        if (width > reqWidth || height > reqHeight) {
            if (width > height) {
                inSampleSize = Math.round((float) height / (float) reqHeight);
            } else {
                inSampleSize = Math.round((float) width / (float) reqWidth);
            }
        }
        return inSampleSize;
    }

}
