Client/server communication between a Java server and an Android phone

I'm looking for the best way to implement data transfer to and from an Android application.

Here's the solution I'm currently considering:

• Data are transferred using JSON, beans are serialized/deserialized using GSON
• Each object that can be transferred provides a "toBean" method and a constructor that takes a bean (enforced with a "Tr开发者_StackOverflowansferable" interface)
• Before serialization I add additional info to the bean such as the response status, time etc.

Does this look like a reasonable solution? is there another pattern I could/should be using?

What you are doing sounds reasonable, I would personally use SOAP/REST web service since it is Java to Java, but that is just a personal choice, the best choice would probably be determined by the details of your interactions with the server as well.
