Why Jetpack Compose is a Must In Your Toolbox

Faster Development

With Jetpack Compose you can build your entire Android UI in Kotlin. This not only requires writing much less code for the equivalent UI than with XML, but also enabled much faster feedback loops in a team by making faster changes.

Supports Multiplatform

Knowing Jetpack Compose does not only allow you to build better Android apps. With Compose Multiplatform you can already build fully functioning apps for iOS, MacOS, Windows, Linux and Web as well – all with one UI codebase.

Apps Are Heavily UI-Driven

The biggest part of almost any mobile app is used for building the user interface. Creating this user interface is therefore a skill that is undeniably required for EVERY mobile developer.

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.

What you will learn in this course

Layouts & Measurements

The Masterclass covers everything about Compose layouts from beginning to end:

  • Basic layouts
  • The layout phase
  • Measurements & Constraints
  • Advanced layouts
  • Custom layouts
  • Subcomposition
  • Custom lazy layouts

Layouts & Measurements

You won’t just learn about which Modifiers there are in Compose – you will truly understand how they work under the hood as well.
The Masterclass covers:

  • Basic layouts
  • Layout Modifiers & Constraints
  • Size Modifiers in-depth
  • Custom Modifiers
  • Composable Modifiers
  • Modifier factories

State Management & Side-Effects

In the Masterclass, you’ll learn everything you need to know about the Jetpack Compose state system. You will learn with practical videos how you can integrate a fully functional and scaling state management system in your apps.

Composition Locals

Truly understand Composition Locals and how they work under the hood in Jetpack Compose. You’ll get clear guidance on how & when to create custom Composition Locals, how you can override existing ones and their different types.

Material3 Theming

You’ll not learn to create a stunning Material3 color theme, but also how you can extract Material3 colors from existing Figma mockups that weren’t created with Material design in mind. You’ll also be able to create global reusable text styles you can apply anywhere in your project.

Animations

After taking the Masterclass, there won’t be a single type animation you won’t know how to create. You’ll learn about all the easier types of animations, as well as low-level animation APIs and fully custom layout animations with LookaheadLayout..

Jetpack Compose Internals

Learn about how Jetpack Compose truly works under the hood. You will get to know the workings of the Compose compiler, the Compose Runtime, the slot table mechanism as well as how the snapshot system works – all while keeping a practical context.

Performance Optimization

No more laggy lists. No more unnecessary recompositions. No more complaints about performance. The Masterclass will teach you ALL performance optimization tricky and when to use which.

Secure your Instant Access

Learn about how Jetpack Compose truly works under the hood.

3 Reasons Why Companies are Shifting To Compose

  • Future-Proof
    It’s no secret that Android nowadays is Compose-first. Companies are starting to realize that and migrate their apps to be ready for the future of mobile development.
  • Saves Money Long-Term
    While migration from XML to Compose requires an invest once, the long-term gain of quicker changes and increased developer productivity remains.
  • Motivated Developers Work Better
    Due to the fast and easy changes Jetpack Compose allows, most developers who shifted to Compose find it way more enjoyable than building UI with XML and Views. A developer who enjoys their work will deliver better results.
