File file = new File(uriString.getPath());
FileInputStream objFileIS = new FileInputStream(file);
ByteArrayOutputStream objByteArrayOS = new ByteArrayOutputStream();
byte[] byteBufferString = new byte[1024];
for (int readNum; (readNum = objFileIS.read(byteBufferString)) != -1;) 
{
 objByteArrayOS.write(byteBufferString, 0, readNum);
 System.out.println("read " + readNum + " bytes,");
}                    
byte[] byteBinaryData = Base64.encode((objByteArrayOS.toByteArray()), Base64.DEFAULT);
