Announcing new Pro Course: Jetpack Compose!

Have you ever wished for an awesome, easy-to-use and fully reusable UI toolkit in Android?

Are you tired of having to write tons of XML code, and prefer to write Kotlin instead?

Jetpack Compose — the new declarative UI toolkit powered completely by Kotlin — is the solution that you've been looking for!

Learn how to build beautiful, powerful and reactive applications using Jetpack Compose in our new Jetpack Compose course!

Keep reading to hear more about it from course instructor Filip Babić:

Why should I take your Jetpack Compose course?

"Jetpack Compose has the potential to completely change the way we write Android apps! It's a brand new, declarative and reusable UI toolkit for Android that relies fully on Kotlin. You no longer have to worry about XML layouts!

I strongly believe everyone will be using Jetpack Compose for their UI development in the near future because it's so simple to use, it's very powerful when it comes to building beautiful UI and it's really fun for building animations.

The Android UI toolkit as we know it will change forever with Jetpack Compose!"

How can this course help with a common pain point in Android development?

"Every single app needs a user interface and you generally want this to be fully reusable and to allow complex styling.

Both of these things are built-in with Jetpack Compose, as all components have a plethora of operators and modifiers to style them, and by relying on composition over inheritance and generic component functions, you can reuse your code not just within the same project, but even between different projects!

Jetpack Compose solves all the pain points the legacy Android UI toolkit has, such as complexity, heavy coupling, lack of reusability, tons of boilerplate code and files, and does it with style!"

Can you please share a cool Jetpack Compose tip with us?

"One of the best things about Jetpack Compose is that you can code completely in Kotlin! This gives you the ability to write powerful and reusable UI components using generic functions, such as:

By defining a generic type of the item you want to delete and an action handler for when you select the delete option, you can apply this dialog to create delete actions for any types of objects you might be showing in your application.

The rest of the UI would be defined in a very generic way too, and you'd have a single dialog to delete all your items:

This makes life easier as you don't have to write a lot of code to achieve similar behavior and to follow the same design style guides!"

Is there anything else we should know about your Jetpack Compose course?

"Jetpack Compose is still in alpha stages, so don't worry if something doesn't work the way you want to, or you can't seem to find a specific component you used to use in XML.

There are more and more resources out there daily, and you can use various communities to ask for help - such as the Kotlin Slack, the Android Study Group, various forums and issue trackers from Google and much more!"
