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

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:org.apache.http.message.BasicLineFormatter.INSTANCE

我在方法onCreate(代码1)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

    }
}

谢谢你的帮助.

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' - >'thank.you.google.http')

确保Apache HttpClient的库存版本与其原始命名空间不重叠的一种方法是使用Maven Shade插件重新打包它,使用由Dirk Boye开发的端口,或Apache HttpClient的官方端口到Google Android.
