can't get the url of a image with jsoup

I'm trying to get the url of a range of images like that:

for(Element img : document.select(".left-column .strillo-content .lazy img[src]")) {
    InputStream input = new java.net.URL(imageMainUrl).openStream();
    Bitmap bitmap = BitmapFactory.decodeStream(input);
    images.add(bitmap);
}

but everytime I trying to run my app I get this warning:

java.net.MalformedURLException: Unknown protocol: data
at java.net.URL.<init>(URL.java:184)
at java.net.URL.<init>(URL.java:127)

so I have tried to print the URL and I get this:

data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7

and I can figure out why, because I'm 100% sure that the element I select is corrent and also I do the same process with other section of the website and it works..

UPDATE 1: I have tried this method to decode the ´base64´ image:

byte[] decodedString = Base64.decode(imageMainUrl, Base64.DEFAULT);
Bitmap bitmap = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length);

but the result is the same..

It's the data URI scheme

http://en.wikipedia.org/wiki/Data_URI_scheme

It allows to add inline data in your URI.

• Extract the base64 part of the URI and get a byte array with parseBase64Binary, more information here : http://docs.oracle.com/javase/7/docs/api/javax/xml/bind/DatatypeConverter.html#parseBase64Binary%28java.lang.String%29
• Use this array to build a ByteArrayInputStream
• Use your BitmapFactory to decode it into a Bitmap

edit

This code works, it give a 1px*1px gif image. I used org.apache.commons.codec.binary.Base64 from commons-codec

String uri = "data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7";
byte[] decodedString = Base64.decodeBase64(uri.substring(uri.indexOf("data:image/gif;base64,") + "data:image/gif;base64,".length()));
ByteArrayInputStream is = new ByteArrayInputStream(decodedString);
FileOutputStream os = new FileOutputStream(new File("/tmp/test.gif"));

byte[] buffer = new byte[1024];
int length;

// copy the file content in bytes 
while ((length = is.read(buffer)) > 0)
{
    os.write(buffer, 0, length);
}

is.close();
os.close();
