Android Client /Java Server and Mysql DataBase Tcp Socket Programming

Question

I have an Android Client which can send a Image to Java server on TCP socket , Java server insert's the Image received into MySQL as a Long Blob and also client ID. Now I want that the Java server to retrieve all the images saved in MySQL for a given client II, and send all the Images to Android client.

Can anyone give an example or any Idea for doing this?

Answer 1

You need to create some API on your server. I would go with the REST JSON API, so that your Android client will make a request to the following URL:

http://yourhost.com/api/images

And the response would be:

[
  {"name":"foo", "url":"http://yourhost.com/foo"}, ...
]

I believe you can achieve that with many Java server-side frameworks, but the idea behind that is: your server receives a request for images, fetches data from DB and writes a response as json/xml/protobuf/whatever your like/.
