Question

美好的一天！

我需要帮助！

我开发了用于集成IIS（SharePoint）的Android应用程序。当我运行此代码（代码2）时，我得到错误

java.lang.NoSuchFieldError的： org.apache.http.message.BasicLineFormatter.INSTANCE

我在方法onCreate（Code 1）

中的firstActivity中运行此代码

版本httpclient - 4.3;

代码1

new Thread(new Runnable() {
            @Override
            public void run() {
                    new HttpsClietn();
    }
}).run();

代码2

    }

感谢您的帮助。

Answer 1

谷歌Android附带了一个非常过时的（pre BETA 4.0）Apache HttpClient分支。由于类路径中存在旧类，HttpClient的库存版本无法正确初始化，除非所有类都移动到另一个名称空间（'org.apache.http' - ＆gt;'thank.you.google.http'）

确保Apache HttpClient的库存版本与其原始名称空间不重叠的一种方法是使用Maven Shade plugin重新打包它，使用Dirk Boye开发的the port或official port of Apache HttpClient to Google Android

对于android删除所有httpclient和httpcore依赖项并添加

compile group: 'org.apache.httpcomponents' , name: 'httpclient-android' , version: '4.3.5.1'    // gradle depedencies

你的build.gradle文件中的

java.lang.NoSuchFieldError：org.apache.http.message.BasicLineFormatter.INSTANCE
