android - Why do some images display black when loading data from a url? -

I am downloading images from a URL and storing them in a SQLite database table. Pictures are profile pictures for users. I store the image of the profile and the user's information in one line.

It mostly works almost all the images are loaded properly in my list However, I have around 300 users who are displayed with a black image. I have verified that by downloading the image through my web browser, users with black images on the URL hold a valid image.

Has anyone ever noticed why some of these users are showing a black image? I do not see any exception.

Here is my code:

  byterefer buff = new bytereferver (50); URL url = new URL (imageURL); URLConnection ucon = url.openConnection (); InputStream = ucon.getInputStream (); BufferedInputStream bis = new BufferedInputStream (is); Int current = 0; While ((current = bis.read ())! = -1) {baf.append (byte) on); }   
 ...  
  // Then byte [] is stored in a SQLite Blob field. Baf.toByteArray ()     
  // Then I'm loading the Blob field in my view like this byte [] bytes = Cursor.gateblob (cursor.gate column index (on db.char.profile_IMAGE_COLUMN)); If (byte! = Null) {ImageView iv = (ImageView) v.findViewById (RID.profile_corean); Iv.setImageBitmap (BitmapFactory.decodeByteArray (bytes, 0, bytes length)); }    
 
 
 A black image is usually a problem with alpha mixed / semi The symptom is the transparent picture I will manually download one of those pictures and to check it with some image editing application it will be detected as the exact format of that image.
