Question

For my application I need to use a captcha for verification. I am using this link for it: http://vocublablair.nl/webservices/send.php

It returns a string something like this: /webservices/simple-php-captcha.php?_CAPTCHA&t=0.59145200+1338304461

Then that link should be called, being: http://vocublablair.nl/webservices/simple-php-captcha.php?_CAPTCHA&t=0.59145200+1338304461

When I call this with the same HttpClient (so with the right session cookie) it gives the following error:

java.lang.IllegalArgumentException: Illegal character in query at index 94: http://vocublablair.nl/webservices/simple-php-captcha.php?_CAPTCHA&t=0.59145200+1338304461

Answer 1

I solved the problem doing the following:

First of all the link I got back had to be HTML encoded using:

Html.fromHtml(String)

Calling the correct URL:

content = sb.toString(); //the fetched link
String myCookie = "";
//get session cookie from other call.

List<Cookie> cookies = ((DefaultHttpClient)httpClient).getCookieStore().getCookies();
for(Cookie c : cookies){
if(c.getName().equals("PHPSESSID")){
    myCookie = c.getName() + "=" + c.getValue();
    break;
   }
   }

URL url = new URL(Html.fromHtml("http://vocublablair.nl" + content).toString());
URLConnection connection = url.openConnection();
connection.setDoInput(true);
connection.setRequestProperty("Cookie", myCookie);
connection.connect();
Bitmap bit = BitmapFactory.decodeStream(new FlushedInputStream((InputStream) connection.getContent()));

I am using a FlushedInputStream. Read about it here: http://twigstechtips.blogspot.com/2011/10/android-loading-jpgpng-images-from-url.html
