Listing 16.18 - safe to use android.hardware.camera?

[jpaone]

This is essentially a repost of the question from the 3rd edition

16.13 android.hardware.camera has been deprecated

The android documentation says that the Camera class was deprecated in API 21, and it recommends using android.hardware.camera2. See Documentation Here Since the minimum API level for this book is 19, will using either the deprecated Camera class or the newer Camera2 class cause any potential issues with Criminal Intent?

In the 3rd edition the Minimum API was 19, now in the 4th edition the Minimum API is 21. Should we be using android.hardware.camera2 ?
