The problem was that once you’ve used an InputStream from a HttpUrlConnection to fetch image metadata, you can’t rewind and use the same InputStream again.
Therefore you have to create a new InputStream for the actual sampling of the image.
Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeStream(is, null, options);
Boolean scaleByHeight = Math.abs(options.outHeight - TARGET_HEIGHT) >= Math.abs(options.outWidth - TARGET_WIDTH);
if(options.outHeight * options.outWidth * 2 >= 200*200*2){
// Load, scaling to smallest power of 2 that'll get it <= desired dimensions
double sampleSize = scaleByHeight
? options.outHeight / TARGET_HEIGHT
: options.outWidth / TARGET_WIDTH;
options.inSampleSize =
(int)Math.pow(2d, Math.floor(
Math.log(sampleSize)/Math.log(2d)));
}
// Do the actual decoding
options.inJustDecodeBounds = false;
is.close();
is = getHTTPConnectionInputStream(sUrl);
Bitmap img = BitmapFactory.decodeStream(is, null, options);
is.close();
