Retrofit/RxJava - get http response code

Question

Android, Retrofit, RxJava. Please look at this example call:

 mcityService.signOut(signOutRequest)
                .subscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe(resp ->
                {
                    busyIndicator.dismiss();
                    finish();
                }, throwable ->
                {
                    Log.d(tag, throwable.toString());
                    busyIndicator.dismiss();
                    Toast.makeText(this,throwable.getMessage(),Toast.LENGTH_LONG).show();
                    finish();
                });

Does anybody know how to get error code (as error number) from throwable? I am able to get full stacktrace or message (as shown above). How to capture error code?

Error code from throwable:

Please look at my screenshot from debug. There is code field, but not accesible — user1209216

apart form the answers check the comment by jake @ github.com/square/retrofit/issues/1218 which means any non 200 errors can be handled in onNext with ` Observable<Response<Type>>` or Observable<Result<Type>> — Raghunandan

Just use casting??

mcityService.signOut(signOutRequest)
                .subscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe(resp ->
                {
                    busyIndicator.dismiss();
                    finish();
                }, throwable ->
                {
                    Log.d(tag, throwable.toString());
                    Log.d(code, ((HttpException)throwable).code());

                    busyIndicator.dismiss();
                    Toast.makeText(this,throwable.getMessage(),Toast.LENGTH_LONG).show();
                    finish();
                });

Also need to check if throwable is actually instance of HttpException. For example, if there is no network available, it's not and app will crash

use instanceOf of your throwable

Retrofit 2 + Rxjava handling error here is your answer

                @Override
            public void onError(Throwable e) {
                if (e instanceof HttpException) {
                    ResponseBody body = ((HttpException) e).response().errorBody();

                    Converter<ResponseBody, Error> errorConverter =
                        application.getRetrofit().responseBodyConverter(Error.class, new Annotation[0]);
                // Convert the error body into our Error type.
                    try {
                        Error error = errorConverter.convert(body);
                        Log.i("","ERROR: " + error.message);
                        mLoginView.errorText(error.message);
                    } catch (IOException e1) {
                    e1.printStackTrace();
                    }
                 }



            static class Error{
            String message;
            }

This really sucks. I wonder why just error code is not accesible from throwable, the same way as error message. Thanks for tip anyway
