apache http client removed since api level 23:

this preview removes support apache http client. if app using client , targets android 2.3 (api level 9) or higher, use httpurlconnection class instead. api more efficient because reduces network use through transparent compression , response caching, , minimizes power consumption. continue using apache http apis, must first declare following compile-time dependency in build.gradle file:

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

android moving away openssl boringssl library. if you’re using android ndk in app, don't link against cryptographic libraries not part of ndk api, such libcrypto.so , libssl.so. these libraries not public apis, , may change or break without notice across releases , devices. in addition, may expose security vulnerabilities. instead, modify native code call java cryptography apis via jni or statically link against cryptography library of choice.
