Re: [android-developers]

You do one thing, copy the output text and validate it in the below link, that will tell you the exact problem, with the exception i see, it looks like it is issue with the JSON output.

I have the following return my webservice created in ruby on rails

  {"created_at":"2013-08-24T02:45:13Z","datebirth":null,"email":"email@gmail.com","firstname":"Ricardo","gender":null,"id":11,"lastname":null,"modelphone":null,"password":null,"password_confirmation":null,"picture":null,"token":"98e58617a9beb77c71de20b3545550e4","typeos":null,"updated_at":"2013-08-25T20:45:25Z"}

This return I'm typing the curl in the console like this:


  curl -v -H 'Content-Type: application/json' -H 'Accept: application/json' -X POST http://localhost:3000/api/v1/sessions.json -d "{\"user\":{\"email\":\"email@gmail.com\",\"password\":\"secret1234\"}}"

and I also have the same return on Android!    I'm using AndroidAnnotations and created the code that calls the webservice
    

    
    @Background
    void login(UserWrapper userWrapper){
    try {
    //Acessa o webservice através de rest passando o objeto UserWrapper que tem o Objeto User
    JsonObject json = userRestClient.login(userWrapper);
    Gson gson = new Gson();
    userWrapper = gson.fromJson(json, UserWrapper.class);
    sucessLogin(userWrapper);
    } catch (RestClientException e) {
    errorLogin();
    }
    }
    

But I am getting the following error
    

    
  08-24 18:34:19.420: E/LoginActivity_(11373): com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING
    
My class is as follows restclient
    

    
    

@Rest(rootUrl="http://192.168.1.100:3000", converters={GsonHttpMessageConverter.class}) @Accept(MediaType.APPLICATION_JSON) public interface UserRestClient {
    
@Post("/api/v1/registrations")
    
UserWrapper addUser(UserWrapper user);
    
@Post("/api/v1/sessions.json")
    
JsonObject login(UserWrapper user);
    
@Get("/users/{id}.json")
    
JsonObject edit(int id);
    
@Put("/users/{id}")
    
void update(User user, int id);
    
@Post("/user")
    
void recoverPassWordUser(String email);
    
    
I know that the return is a String from my server, but I need to get a JSONObject. I also know I need to use a parse, so I made the following way by changing my code
    
    

String json = userRestClient.login(userWrapper);
    
JsonParser parser = new JsonParser();
    
JsonObject jsonObject = parser.parse(json).getAsJsonObject();
    
Gson gson = new Gson();
    
userWrapper = gson.fromJson(jsonObject, UserWrapper.class);
    
sucessLogin(userWrapper);
    


But I get the error the following error:

  
    08-25 18:31:17.945: E/LoginActivity_(13266): org.springframework.http.converter.HttpMessageNotReadableException: Could not read JSON: java.lang.IllegalStateException: Expected a string but was BEGIN_OBJECT at line 1 column 2; nested exception is com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected a string but was BEGIN_OBJECT at line 1 column 2
    
When I change to receive a JSONObject error says that is a String, when I change a String to receive the error says that is a JSONObject.
    

    
Help-me
