Java 即使已在onError中处理，仍引发了Reform2.HttpException

当google+响应错误json时，我总是收到一个未处理的异常

retrofit2.HttpException: HTTP 404 
                         at retrofit2.RxJavaCallAdapterFactory$SimpleCallAdapter$1.call(RxJavaCallAdapterFactory.java:159)
                         at retrofit2.RxJavaCallAdapterFactory$SimpleCallAdapter$1.call(RxJavaCallAdapterFactory.java:154)
                         at rx.internal.operators.OperatorMap$1.onNext(OperatorMap.java:54)
                         at retrofit2.RxJavaCallAdapterFactory$CallOnSubscribe.call(RxJavaCallAdapterFactory.java:109)
                         at retrofit2.RxJavaCallAdapterFactory$CallOnSubscribe.call(RxJavaCallAdapterFactory.java:88)
                         at rx.Observable$2.call(Observable.java:162)
                         at rx.Observable$2.call(Observable.java:154)
                         at rx.Observable$2.call(Observable.java:162)
                         at rx.Observable$2.call(Observable.java:154)
                         ....

在该法典中：

Observable.create(new Observable.OnSubscribe<String>() {
        @Override
        public void call(Subscriber<? super String> strSub) {
            // Getting ID
            strSub.onNext(AccountUtils.getAccountId(appContext));
            strSub.onCompleted();})

          .subscribeOn(Schedulers.io())
          // Get Google+ Image through Retrofit2
          .flatMap(str -> createGPlusUserObservable(str, AccountUtils.ANDROID_API_KEY))
          .map(this::setprofileImage)    // I don't see Timber.d message inside that method!
          .compose(binder)
          .observeOn(AndroidSchedulers.mainThread())
          .subscribe(subscriber);

所以问题是-如果我在订户的onError（Throwable e）中处理它，为什么会得到未处理的异常

谢谢

我认为这是因为在将纯html字符串转换为我的GPlusUser类时，改装工厂逻辑时发生了错误

我通过

可观察的响应
和
响应来处理纯html，从而消除了控制台日志中令人讨厌的异常。isSuccess（）
您可以发布“setprofileImage”的代码吗？请参阅更新。谢谢
