First, doing String.getBytes() involves converting the string into some random encoding. You may know what encoding it happens to be on Android devices, and perhaps it even won't change depending on what country the device is being used in -- but me, I would never go NEAR that method. Do not use it for any purpose; any use of it is sure to be a bug. I have fixed an ENORMOUS number of bugs in people's code, where the sole cause was calling this method.
Originally, your data is received via SAX as a char[] array, not a string. That would be closer to what you want, in theory --- but: Critical point: YOU CANNOT SEND UNENCODED BINARY DATA VIA XML. It's not just that some characters have to be quoted. Some byte sequences are not legal characters. When encountering these, a conforming parser with throw an exception -- because it is not XML. If the web service is actually doing this, the web service needs to be redone. More likely, the web service is sending the data encoded; for example, it could be using Base64 encoding. You can work with this as a string if you want (though that involves extra memory usage), but you have to decode it to get the byte[] you'll need to construct the bitmap.
