Android 4.1+ enable TLS 1.1 and TLS 1.2
I recently had to work on an Android application that consumed an API which removed support for TLS 1.0 connections for security reasons.
The Android documentation for SSLSocket says that TLS 1.1 and TLS 1.2 is supported within android starting API level 16+ (Android 4.1, Jelly Bean). But it is by default disabled but starting with API level 20+ (Android 4.4 for watch, Kitkat Watch and Android 5.0 for phone, Lollipop) they are enabled. But it is very hard to find any documentation about how to enable it for phones running 4.1 for example.
