android - java.lang.NoSuchFieldError : org. apache.http.message.BasicLineFormatter.INSTANCE 错误

Question

美好的一天!

我需要帮助!

我通过集成 IIS(SharePoint) 为 Android 开发应用程序。 当我运行此代码(代码 2)时，出现错误

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

我在 firstActivity 的 onCreate(Code 1) 方法中运行这段代码

版本 httpclient - 4.3;

代码 1

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

代码 2

package com.example.HttpsMy;

        CredentialsProvider credsProvider = new BasicCredentialsProvider();
        credsProvider.setCredentials(AuthScope.ANY, new NTCredentials("Grigoriy.Polyakov","password", "", "domain.kz"));

        HttpClientContext context = HttpClientContext.create();
        context.setCredentialsProvider(credsProvider);

        HttpGet httpget = new HttpGet("https://serveer.domain.kz");


       HttpClient client = HttpClientBuilder.create()
               .setSSLSocketFactory(getFactory())
               .setDefaultCredentialsProvider(credsProvider)

               .build();

        System.out.println(client.execute(httpget,context).getStatusLine());

    }

    SSLConnectionSocketFactory getFactory() throws CertificateException, UnrecoverableKeyException, NoSuchAlgorithmException, KeyStoreException, KeyManagementException, IOException {
        return new SSLConnectionSocketFactory(getContext());
    }
}

感谢您的帮助。

Google Android 附带了一个极其过时(BETA 4.0 之前)的 Apache HttpClient 分支。由于类路径上存在旧类，除非将所有类都移动到另一个命名空间('org.apache.http' -> 'thank.you.google.http')，否则 HttpClient 的标准版本无法正确初始化

确保 Apache HttpClient 的库存版本不与其原始命名空间重叠的一种方法是使用 Maven Shade plugin 重新打包它。 , 使用 the port由 Dirk Boye 或 official port of Apache HttpClient to Google Android 开发.
