In the first section, you’ll learn what CI/CD is, why it’s used and you’ll get to know Bitrise – the CI/CD provider we’ll use in this course.That way, nobody gets left behind.
Here, we’ll directly dive into practice. In this section, you’ll build an actual app in a simulated corporate environment.
This is what you’ll learn:
This section is all about delivering your app to those who will use it.
This is what you’ll learn here:
In the practice part of the course, you’ll build a Material3 clone of the Google Pixel calculator. For this app, you’ll write some real unit and UI tests you’ll then use to automatically verify with your CI pipeline that everything works as expected. This type of app was carefully chosen, since it allows us to write a lot of useful test cases without having a huge project that would shift away the focus of this course from CI/CD.




CI stands for continuous integration and is all about automating the decision whether you want to integrate one branch into another.
Merging one branch (e.g. a new feature branch into the production branch) can be quite dangerous in practice, as you can easily include bugs and issues in your production code. To minimize these risks and enable faster feedback loops, you can setup CI pipelines which will automatically run your app’s unit tests, UI tests, run a linting tool and so on. To implement this, there are plenty of different providers you can choose from. In this course, you’ll learn about Bitrise, but the concepts can be transferred to other providers as well.
CD stands for continuous delivery is about automating the delivery of your app to either a group of testers or to your actual user base.
With a correctly set up CD pipeline, you can speed up your development by a lot, since you can automate updating your app on Google Play. Therefore, there is no more need to manually upload your APK to Google Play and configuring everything by hand.



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.
