问题
I am developing an application for API level 19 (KitKat).
I have a LocalDateTime object and a Duration object. I need to add this Duration to LocalDateTime.
Android Studio shows that plus(TemporalAmount) method of LocalDateTime class is avaliable since API level 26 which is Oreo and it supports less than 1% of devices right now.
How can I do it with API level 19?

The bbb answer in the comments is correct.
Currently the best option for android is ThreeTenABP. Jake Wharton explains why it's better to use this library rather than Joda-Time and ThreeTenBP in Android.
