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 (1.3.2) 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.
