This part will teach you all the basics about working with a canvas and finishes off with a very detailed video about making a practical weight picker composable.
- The canvas coordinate system
- Basic shapes
- Sin, Cos, Tan – Trigonometry made easy
- Polar coordinates
- Detecting touch input (making a ball clicker game)
- Drawing text
- Making a weight picker composable
- Exercise for practice
3. Paths
This part will focus on drawing paths and using them to create custom shapes and animations.
- What is a path?
- Path basics
- Path operations

This Is What You Will Build






Philipp Lackner has over 14 years of experience in the software field. Over the past years, he built a following of over 250,000 developers on social media who trust his work. With over 25,000 sold copies of his courses and 1,000h+ spent for teaching Android concepts, he already helped hundreds of thousands people to learn practical skills they can immediately apply.
He has a degree in computer science, however it didn’t go as expected. The amount of theory that was taught in university made him think about a better approach to learn what is really needed in the real world. Over time, Philipp found mentors who taught him exactly that in a practical setting. That was the game changer for his career.
After having worked for dozens of companies around the globe as a consultant, Philipp now wants to teach other Kotlin developers what really counts for becoming an outstanding developer in today’s competitive industry.
