After the Android Internals course, you will…

Build more stable apps

The Android OS imposes lots of restrictions and rules. You have to know these in order to make your app work well and not face surprising crashes and bugs.

Gain an expert status on the market

While most Android developers see their apps as an isolated piece of code true expertise comes from understanding how your app integrates in the bigger system and how it works best with it. This is your chance to stand out as a native Android expert.

Have an enlarged mental model

Learning about internals expands your mental model. It allows you to think about bugs and problems from new angles. This knowledge will help you better understand error messages and documentations, so overall development and learning will be massively accelerated.

Stand out from AI-taught generalists

AI makes general knowledge more and more accesible. What sets you apart from the mass is specialized knowledge in a specific niche – one of the biggest weaknesses of AI models as there are only very few resources to learn from about specialized knowledge.

Master the Android OS

Philipp Lackner has over 13 years of experience in the software field. Over the past years, he built a following of over 200,000 developers on social media who trust his work. With over 10,000 sold copies of his courses and 700h+ 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 mobile developers what really counts for becoming an outstanding developer.

What you will learn in this course

Android OS System Architecture

Get a deep dive into how the Android OS is structured. This starts at the deepest level, the Linux kernel and goes up to higher levels covering processes, main thread, loopers, handlers, system services, the DVM & ART as well as native code & the JNI.

Activities Under the Hood

Learn how Activities really work under the hood, how the Activity Result Registry works and what you can do to securely restore Activity state.

ViewModels

Truly understand how ViewModels work behind the scenes and how they achieve to survive configuration changes like screen rotations.
You’ll even learn to implement your own ViewModel framework that imitates the official one to really understand how it works.

Views & UI

How does a UI component even end up on the screen after defining it in our code? This and many more questions are answered in this section. You will learn about concepts like windows, surfaces, custom views, Composables and Android’s overall rendering pipeline.

Inter-Process Communication (IPC)

Whether you’re aware or not, every Android app has to communicate with other apps or system processes all the time.
This section deep-dives into all of Android’s mechanisms that allow high-performing communication with other apps and components.

Android’s Security System

Understand how Android’s sandboxing model works and how you protect your app against various different security risks to prevent malicious apps from doing serious harm to your app.

Memory Management

Learn how the OS decides about your app’s memory usage, how you avoid OutOfMemoryErrors and how you profile your app for memory related issues like memory leaks.

Battery Management

There’s no battery-less phone, which is why Android imposes rules and restrictions regarding how much power your app can use at a given time.
This section covers these restrictions and how you best set up your app to ensure a user-friendly experience.

What Most Android Devs Think Building Robust Apps Is All About:

What Actually Belongs to It:

“You can’t learn to accelerate, break and steer a car and expect to be a good driver – what you lack are the traffic rules. The same is the case on Android: As long as you see your Android app as an isolated piece of software, it will stay the slave of the OS.”
