public static String urlToBase64(String fileUrl) throws IOException {

		ByteArrayOutputStream data = new ByteArrayOutputStream();
		byte[] buff = new byte[2048];
		InputStream inputStream = null;
		URL url = new URL(fileUrl);
		HttpURLConnection conn = (HttpURLConnection) url.openConnection();
		conn.setDoInput(true);
		conn.connect();
		inputStream = conn.getInputStream();
		int num = -1;
		while ((num = inputStream.read(buff)) != -1) {
			data.write(buff, 0, num);
		}
		String baseStr = Base64Util.encode(data.toByteArray());
		return baseStr;
