尽管设置为OkHttp客户端，但改造超时不会改变

Question

我有一个用于网络连接的单例类。我希望超时增加，并编写了以下代码。

 BizAnalystApiv2 provideBizAnalystApiV2(final ObjectMapper mapper) {

    final HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
    if (BuildConfig.DEBUG) {
        logging.setLevel(HttpLoggingInterceptor.Level.BODY);
    } else {
        logging.setLevel(HttpLoggingInterceptor.Level.NONE);
    }

    final OkHttpClient client = new OkHttpClient.Builder()
            .addInterceptor(logging)
            .addInterceptor(new Interceptor() {
                @Override
                public Response intercept(Chain chain) throws IOException {
                    Request original = chain.request();
                    Request request = original.newBuilder()
                            .header("instanceId", FirebaseInstanceId.getInstance().getId())
                            .build();
                    return chain.proceed(request);
                }
            })
            .readTimeout(70, TimeUnit.SECONDS)
            .build();



    return new Retrofit.Builder()
            .addConverterFactory(JacksonConverterFactory.create(mapper))
            .client(client)
            .baseUrl(BizAnalystServicev2.getServerUrl())
            .addCallAdapterFactory(RxJavaCallAdapterFactory.create())
            .build()
            .create(BizAnalystApiv2.class);
}

超时保持在15秒，这是默认超时。你能说明问题是什么吗？

我正在使用okhttp（v 3.4.1）和改装（v 2.1.0）
