have a method in my android app which uses HttpPost class. It was working fine with targeted sdk 4.4.2 but i've made some changes and made the targeted sdk to 23(6.0). Now HttpPost class is giving error. I've also read about HttpUrlConnection but don't know how to use it. Here is my BaseActivity, i extend this class in my other activites and this is working find with SDK 4.4.2 but not with sdk23 please help

Context context;
