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:

Gallup

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

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>> – Bisectrix

Answer 1

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 – Gallup

use instanceOf of your throwable – Criseyde

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 – Gallup
