Can we use Optionals in Android programming?

Question

I have been reading about the Optional type in Java 8. I want to implement in some of my Android code.

But does the Dalvik machine for the latest versions of Android

Answer 1

Yes. But only on API level 24 / Nougat (in current time of writing).

For pre-Nougat, you may opt to these libraries:

• Options (https://github.com/tomaszpolanski/Options)
• Arrow (https://github.com/android10/arrow)
• StreamSupport (https://github.com/streamsupport/streamsupport)
• Optional (https://github.com/MrHadiSatrio/Optional)
• Guava (https://github.com/google/guava)
