Getting JSON from RetrofitError object using Retrofit

Question

I am using the Retrofit library to do REST calls to a service I am using.

If I make an API call to my service and have a failure, the service returns a bit of JSON

Answer 1

I compile many answer and wrote some code to achieve something nicer :

{
    "errors": {
        "email": [
            "Email not valid.",
            "Unable to find the user toto@toto.fr."
        ]
    }
}

I take all item in 'email' and display them concatained with Guava Joiner:

String json =  new String(((TypedByteArray)error.getResponse()
    .getBody()).getBytes());

Map map = new Gson().fromJson(
    json, new TypeToken>>>() {}.getType());

try {
    List errorsEmail = 
        (List) ((Map)map.get("errors")).get("email");
    Toast.makeText(getApplicationContext(), Joiner.on("\n")
        .join(errorsEmail), Toast.LENGTH_SHORT).show();
} catch(Exception e){
    Log.e(Constants.TAG, e.getMessage());
}
