Google had been telling us for quite some time that the Apache HTTP Client was deprecated and going to be removed, and with the release of Marshmallow (API 24) this came true. For the vast majority of developers, this is a non-issue. The HttpUrlConnection object is more than adequate. But for some enterprise developers, this presented a problem. The HttpUrlConnection does not support NTLM (Microsoft Active Directory) authentication. But the Apache client does. If you are using or want to use the Apache client, it is still possible. Simply add this to the android section of your build.gradle:
android {
useLibrary 'org.apache.http.legacy'
}
Now when you build the Apache client becomes available again. It’s still marked as deprecated and Android Studio will complain, but it definitely works.
