The best thing you can do is to implement JSON with a RESTFUL Web Service.
More info:
JSON.ORG
How to create a JSON response
Android includes JSON classes such as JSONArray, JSONObject that can be used to interpret the response the Web Service will return. See more at here.
You can't go wrong. JSON is fast, there are ways to secure the communication if you implement RESTFUL Authentication.
Best of all your Web Service will be compatible with iOS Apps and any other platform with JSON support.
Good luck!
