The previous tutorials were aimed at beginners to android but over time have been getting more complex as the original camera_intent app has developed.
This tutorial series is more aimed towards the intermediate developers thought for those who have been following the previous tutorial series, feel free to watch this android performance series.

Android studio (1.5) is the editor of choice (IDE) for this tutorial series.

This tutorial series is the start of what I expect to be many so I encourage comments and feedback to improve the quality and viewing experience.

Hi Nige, I really much appreciate your video, I really have no idea of Camera2 API and it's flow before, but after watching this, it really clears me out of Camera2 confusion.
I am currently having a college project of making an app based on Face Recognition, and I would like to validate / recognize the face in the back-end instead of FE, my biggest obstacles in this time is to implement the image stream to API, by using Camera2 guided by your tutorial, it's just become far more clear now. Thanks a lot Nige! I wish you all the best. I send my honor to you from Indonesia

Hi, your tutorials have helped me learn a lot. When I capture a still image from the camera preview, I rather than save the Image am trying to send the byte array to a new activity and then create a bitmap and display it on screen. the image is rotated incorrectly. Have I done something wrong or is there an issue with the camera 2 api that I have not dealt with?

Hi. nice to meet you. I live in South Korea. I'm developing Communications System. I have a question. I want to use the Android Camera2 API. So, I want to control the SmartPhone Camera 'Focal Length' for optical zoom using Android development. I have a Samsung Galaxy S6 OS 6.1. Is this possible focal length control for optical zoom?
I request answer for this question, Please. Thank you.
