REST service and Android client

Some time ago I tried to develop pet application with Guice+Restlet and deploy to GAE. The main idea was to expose several REST services and access to them from android and web clients. I didn’t finished it due to lot issue with restlet. So I decided trying MVC REST and spring android-rest-template. It works wonderful. Just few lines and that’s it. As usual I run server part on GAE
This is example of my REST service

@Controller public class RestService implements IRestService { final Logger logger = LoggerFactory.getLogger(RestService.class); @Override @RequestMapping(“/changeState/{id}/{state}”) @ResponseBody // @ResponseStatus(value=HttpStatus.NO_CONTENT) public String changeState(@PathVariable(“id”) int placeId, @PathVariable(“state”) String state) { logger.debug(“Called service with id{} and state {}”, id, state); return “OK”; } }

And here you can see corresponding android client

public void changeState(View view) { String stateValue = view.getTag().toString(); String url = “http://192.168.1.104:8888/Places/changeState/{id}/{stateValue}”; // Create a new RestTemplate instance RestTemplate restTemplate = new RestTemplate(); // Add the String message converter restTemplate.getMessageConverters().add(new StringHttpMessageConverter()); // Make the HTTP GET request, marshaling the response to a String String result = restTemplate.getForObject(url, String.class, 1, “SpringSource”); }

So if you need build REST service and call it from android app, I recommend to use given spring solution
