I try this solution but it did not work anymore, even if I do "System.gc()" to call the garbage collector after setting to null the variable (calling this method does not guarantee that the garbage collector will actually be run).
However, I manage to solve my problem resizing the image. First I get the image size using : BitmapFactory.decodeStream(InputStream is, Rect outPadding, BitmapFactory.Options opts) and setting opts.inJustDecodeBounds to true (to save memory). Image size is then got with opts.outHeight and opts.outWidth. Then, I calculate and set opts.inSampleSize value judging from the maximum image size I want. Finally, I call again BitmapFactory.decodeStream(InputStream is, Rect outPadding, BitmapFactory.Options opts) and get the resized image.
