This post is for anyone who has ever wanted to load an image from a given URL and turn it into a Bitmap which you can then use to set as an ImageView’s background, or upload as a Contact’s photo, etc.

So here it is,

 
         public 
         static 
         Bitmap getBitmapFromURL(String src) {
        
         try 
         {
        
         URL url = 
         new 
         URL(src);
        
         HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        
         connection.setDoInput(
         true
         );
        
         connection.connect();
        
         InputStream input = connection.getInputStream();
        
         Bitmap myBitmap = BitmapFactory.decodeStream(input);
        
         return 
         myBitmap;
        
         } 
         catch 
         (IOException e) {
        
         e.printStackTrace();
        
         return 
         null
         ;
        
         }
        
         }

Nothing too complicated – simply create a URL object using the “src” string (i.e. String src = “ http://thinkandroid.wordpress.com”), connect to it, and use Android’s BitmapFactory class to decode the input stream. The result should be your desired Bitmap object!
