HttpLoggingInterceptor causes stackoverflow

I have this class to create a service with retrofit2 + rxandroid + okhttp.

public class ServiceCreator {

    private static OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
    private static final int DEFAULT_TIMEOUT = 30; //seconds

    private static Gson gson = new GsonBuilder().setDateFormat("yyyy-MM-dd'T'HH:mm:ss").create();
    private static RxJavaCallAdapterFactory rxAdapter = RxJavaCallAdapterFactory.createWithScheduler(Schedulers.io());

    private static Retrofit.Builder builder = new Retrofit.Builder()
            .baseUrl(BuildConfig.REST_BASE_ENDPOINT)
            .addConverterFactory(GsonConverterFactory.create(gson))
            .addCallAdapterFactory(rxAdapter);

    public static <RESTService> RESTService createService(Class<RESTService> service, String userToken) {

        if (BuildConfig.REST_DEBUG) {
            HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
            logging.setLevel(HttpLoggingInterceptor.Level.BODY);
            httpClient.addInterceptor(logging);
        }

        if (StringUtils.isNotBlank(userToken)) {
            httpClient.addInterceptor(chain -> {
                Request original = chain.request();

                Request request = original.newBuilder()
                        .header(Constants.AUTHORIZATION_HEADER, userToken)
                        .method(original.method(), original.body())
                        .build();
                return chain.proceed(request);
            });
        }

        httpClient.connectTimeout(DEFAULT_TIMEOUT, TimeUnit.SECONDS);
        httpClient.readTimeout(DEFAULT_TIMEOUT, TimeUnit.SECONDS);
        httpClient.writeTimeout(DEFAULT_TIMEOUT, TimeUnit.SECONDS);

        Retrofit retrofit = builder.client(httpClient.build()).build();
        return retrofit.create(service);
    }

    public static Retrofit retrofit() {
        return builder.client(httpClient.build()).build();
    }
}

This code causes an stackoverflow error in android kitkat.

But if I remove this line of code, works perfect.

        if (BuildConfig.REST_DEBUG) {
            HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
            logging.setLevel(HttpLoggingInterceptor.Level.BODY);
            httpClient.addInterceptor(logging);
        }

I have uses this class without RxAndroid and works perfect with this versions:

compile 'com.squareup.retrofit2:retrofit:2.0.2'
compile 'com.squareup.retrofit2:converter-gson:2.0.2'
compile 'com.squareup.okhttp3:okhttp:3.2.0'
compile 'com.squareup.okhttp3:logging-interceptor:3.2.0'

Nowadays I’m using:

compile 'com.squareup.retrofit2:retrofit:2.1.0'
compile 'com.squareup.retrofit2:converter-gson:2.1.0'
compile 'com.squareup.retrofit2:adapter-rxjava:2.1.0'
compile 'com.squareup.okhttp3:okhttp:3.4.1'
compile 'com.squareup.okhttp3:logging-interceptor:3.4.1'

Also I have created a stackoverflow question: http://stackoverflow.com/questions/40441957/retrofit-rxandroid-causes-stackoverflow-error-on-kitkat

Thanks

I wonder if this has to do with https://github.com/square/okhttp/issues/2961 as well.

I fixed it by setting the log level to headers.

            logging.setLevel(HttpLoggingInterceptor.Level.HEADER);

@dibyendumr Glad to help. Thank you for the great library.
