java - BitmapFactory.decodeStream(stream, null, options) の場合は InputStream を再利用します

Question

InputStream stream = new URL(key).openStream();

BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;

BitmapFactory.decodeStream(stream, null, options);

options.inSampleSize = calculateInSampleSize(options, reqWidth,
            reqHeight);
options.inJustDecodeBounds = false;

/* i need reuse stream here, for decode stream again. */

Bitmap bmp = BitmapFactory.decodeStream(stream, null, options);

stream.close();

return bmp;
