public Observable<Weather> fetchWeather(final String city) {
        return apiService.mWeatherAPI(city, C.HEFENG_KEY)
                .subscribeOn(Schedulers.io())
                .unsubscribeOn(AndroidSchedulers.mainThread())
                .observeOn(AndroidSchedulers.mainThread())
                .flatMap(new Func1<WeatherAPI, Observable<WeatherAPI>>() {
                    @Override
                    public Observable<WeatherAPI> call(WeatherAPI weatherAPI) {
                        String status = weatherAPI.mHeWeatherDataService30s.get(0).status;
                        //出错
                        if ("no more requests".equals(status)) {
                            return Observable.error(new ApiException(100));
                        } else if ("unknown city".equals(status)) {
                            return Observable.error(new ApiException(101));
                        }
                        return Observable.just(weatherAPI);
                    }
                })
                .map(new Func1<WeatherAPI, Weather>() {
                    @Override
                    public Weather call(WeatherAPI weatherAPI) {
                        return weatherAPI.mHeWeatherDataService30s.get(0);
                    }
                });
    }

api次数用完后 return Observable.error(new ApiException(100)); 程序闪退是什么原因？
