                    new HttpsClietn();
    }
}).run();

Code 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)
               .setSslcontext(getContext())
               .build();

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

    }

    }
}

Thanks for any help.

For android remove all httpclient and httpcore dependencies and add

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

in your build.gradle file

Google Android ships with an extremely outdated (pre BETA 4.0) fork of Apache HttpClient. Due to the presence of old classes on the classpath the stock version of HttpClient fails to initialize correctly unless all classes are moved to another namespace ('org.apache.http' -> 'thank.you.google.http')

One way of making sure the stock version of Apache HttpClient does not overlap with its original namespace is repackaging it with the Maven Shade plugin, use the port developed by Dirk Boye, or the official port of Apache HttpClient to Google Android.
