Today, when I wrote the Internet connection, I found that API 23 could not find HttpClient, and the official documentation seemed to say so.

This interface is deprecated in API level 22.Please use OpenConnection () instead. Please visit the webpage for further details.

Then only find a way, and really found:

To continue using the Apache HTTP APIs, you must first declare the following compile-time dependency in your Build.gradle File

Do not need to copy Sdk/platforms/android-23/optional/org.apache.http.legacy.jar into Libs folder, System Auto Recoginise itself.

Android {        uselibrary ' org.apache.http.legacy '  }

Proguard Cofig:
