Calling a web service to obtain an byte[] in Android

I've writing a application on Android which calls a .Net restful wcf web service I've written. I'm successfully obtaining XML and String results, but cannot call a method on the web service which returns a byte[] - it looks like its encoding is alerted.

I am using the org.apache.http.HttpHost library and an currently reading the byte[] as a string (the encoding in eclipse looks like unicode);

     InputStream in = response.getEntity().getContent();
        BufferedReader reader = new BufferedReader(new InputStreamReader(in));
        StringBuilder str = new StringBuilder();
        String line = null;
        while((line = reader.readLine()) != null){
            str.append(line);
        }

        in.close();
        String asciiString = str.toString();

Basically I want to convert the data held in asciiString to a Bitmap (the WCF serv开发者_开发技巧ice outputs a byte[] of a PNG image)

If anyone can offer pointers as what I am doing wrong or how to do this (if it is possible) it would be most welcome.

Many thanks

I believe you should use a ByteArrayOutputStream. I don't have an IDE installed here, but here's how I think it should go: open a ByteArrayOutputStream, to which you write byte by byte (or better, buffering in some way, of course) what you read from your InputStream in. To obtain your byte[] use the method toByteArray().
