Answer 1

sizin build.gradle da eklerseniz ima nasıl bilmek istiyorum:

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

Veya bunun yerine HttpURLConnection class kullanın.

Answer 2

DefaultHttpClient ve NameValuePair sınıfları API düzeyinde 22 kullanımdan kaldırılmış ve Google bile onlar için belgeleri indirdi 23.

API düzeyinde çıkarıldı.

Dokümantasyon hala devam ettiğinde, bunun gibi temel görevler için HttpUrlConnection'a geçmeniz önerilir.
