I created a 78 video tutorial series, covering all main aspects of developing an android app with Android Studio.
Code available at github: https://github.com/zorani/Droid101
Youtube Videos here: https://youtu.be/2YnD0gyr98s
I covered all the basics, even some more advanced topics such as animation and basic physics.
All a lot of fun, and helps develop intuition for game development.
Then I discovered Unity, oh boy...
Please see all the comments on my channel, happy people.
Please also help yourself to watching the videos, although not Unity related, great intuition can be
gathered by returning to fundamentals, and you will appreciate unity more.
