java - I can not serve a JSON response with Play framework 2.1 -

I'm trying to export json to an Android device. I've used it like Java like Play! Doctor: But this does not work. I know that this is not an Android problem because I did it with php return json_encode ($ some) and it works well, what can I do?

  Package Controller; Import java.util.list; Import org.codehaus.jackson.node.ArrayNode; Import org.codehaus.jackson.node.ObjectNode; Import model Restaurant; Import play.libs.Json; Import play.mvc *; Public Class Servicio Controller {Public static result coordination () (//System.out.println (= XXXXXXX ") is expanded; Object node RPTA = Jason.NOBackJack (); Arrayode Restaurant = RPTAAirode (); List & lt ; Restaurants & gt; Rests = Restaurants & Restaurants; for rest in the restaurant (int i = 0; i & lt; rests.size (); i ++) {rest = rests.get (i); ObjectNode RestJs = Json.newObject (); RestJs.put ("nombre", rest.nombre); RestJs.put ("LAN", rest.longitud); RestJs.put ("lat", rest.latitud); restaurantses.add (RestJs);} ObjectNode response = Json.newObject (); Response.put ("Restaurants", R Levels); Return is OK (response);}   
}  
 I met DB and the browser shows me:
