As far as I know you have to convert the PDF in to base64 and then send it. The best approach to do this would be to use the built in Base64 class that comes with Android and use the method encodeToString to convert your file in to a base64 string.

How to convert file to bytes

File file = new File(path);
int size = (int) file.length();
byte[] bytes = new byte[size];

BufferedInputStream buffer = new BufferedInputStream(new FileInputStream(file));
buffer.read(bytes, 0, bytes.length);
buffer.close();
