A lot of tutorials online and on youtube tend to be code-along style which is often bad for new learners. Most of the stuff end up forgotten and many features already used in code are unknown to them too. Like how to write first unit tests (but the test example code has DI, Room, MVVM etc). Better way would be how to write tests for basic sum methods , then for basic gestures , then for the view model and so on . Simple things first are the best way to go before more intermediate and practical stuff. Cheat-sheets are gold too. Tutorials covering them even more so . Video like this crash course is quite great .
if any1 hated writing "modifier = Modifier" as much as I did; (or something else I guess) Go to file->settings->Live Templates and press the "+" then put your preferred abbreviation, in my case "mod" and to Template text write "modifier = Modifier". Now, whenever you write mod and then press tab it autocompletes
This is exactly what I needed, thank you! Returning to Android development after not doing it for a few years, I was like, "What the heck is this Composable stuff?!"
Man, you've just inspired one more person to get back to his projects. I mean its illegal for recycler view to be so simple. You've got a talent to teach things.
Philipp, just wanna say big big thanks for your contributions you are really making a big difference in people's lives and for android development in general. I finally got an android job a month ago and your videos helped me big time through my journey. I am currently refactoring code with bad practices and your big focus on patterns and good code is making a difference even here in Sweden. Next I wanted to learn jetpack compose and boom, you come with an awesomely packaged video. Thanks again man and looking forward to more content.
Just brilliant.. Excellent Phillip..I have been using Android XML files all these years.. U explained the basics of Jetpack Compose so well that makes u feel that it's easy, interesting and learnable . Thanks.
Thank you so much for making this great tutorial!!! i have been wanting to create apps for so long and i never really liked the way designing UI worked, and i LOVE this way using code to make UI!
Hey Philipp, ich hab bei dir häufig das Gefühl, dass du genau das Video machst, was ich in diesem Moment brauche. Nicht nur hier, sondern auch in vielen anderen Fällen in der Vergangenheit. Auch deine Shorts sind fast immer hilfreich! Vielen Dank für deinen absoluten top content!
I am from india and i loved ur content i started ur playlist from basics of kotlin... And ur way of explaning concept is ossum . thanks for this ossum content .....🔥🔥🔥🔥
i never worked with Compose, and just a little bit with XML. Also i started to learn Kotlin. And as an Professional Java Developer i can say: This Video is Awesom, with Compose App-Development feels easier like never before! Also i like that you share your knowlege with us! Good Job!
No matter how much I thank you, I will never give you the thanks you really deserve, Philip ♥️ You are truly a person of great value to the Android and mobile developer community in general I wish you all the best and give us more ♥️🙏🇪🇬
Best android introduction, straight to point and gives you idea about how things work ui wise , how ui renders , kind of give beginners like me a starting point to explore. Just want to say thank you very much man, and really appreciate all of your efforts.
thank you for this guide. just got into kmp and was watching your video, when you you mentioned that you also have compose guides that one should watch so i did now. I am currently searching for a software dev job as i freshly graduated. But it takes so much time that i though fk it, i ll develope an app and publish it and your videos are a great entry
This tutorial was just great to get me up and going. I learned Java and XML in my uni course but I thought it would be better to switch to Kotlin and JetCompose. Thanks a lot for this man! Its much better than the tutorials on the android website
This video is very, very clear and easy to follow and understand. I'm very, very thankful for you, it makes me to start get the idea of jetpack compose, and for sure this is the future of Android UI Design
This is exactly what I needed in native Android development! The syntax is so cool and easy to understand if you are familiar with React or Flutter. Much better than XML of course! I think I might go all in native if I continue to use Jetpack Compose! Thanks a lot Phillip!
hi from Greece. You were the one who introduced me to xml and now you are the one who introduced me to compose. You explain things very well and the pace is just right. THANK YOU.
Man, i wish this type of vid was abailable on yt when i was just starting, this will be very helpful to new compose learners. Great content as always philipp
I am Learning Compose, and Unlike many other ways of learning I have used before, I find mixing the Docs and Your tutorials Yours only, to be working. I dont want to go into the tutorial loop just yet, maybe later on when I get most of the basic conepts and can now make the skills as diverse as they can be
Hey, Philipp. Danke dir für all deine tollen Videos!! Du erklärst super gut und hilfst mir so sehr in verschiedene Topics einzusteigen und zu wissen, was man alles können sollte, um eine gute Android Developerin zu werden.
Great video. I love this declarative way of UI programming. I did a lot QML before but now I have to switch to Kotlin and was really afraid of diving into XML^^ In your video there is just one point that I do not understand: why is it necessary to assign the new text value to the member text value inside the onValueChanged ? Actually I would assume that this slot is called when changing the member. At least in QML it is how it works.
Phillipp, Thanks for your excellent content, if you make an entire Android course and Upload it to Udemy/TH-cam, which is ok if it is paid course which includes all basics and some projects that help many Android (jetpack) learners, you have a 10 week course on your official site. Still, as a student, that is not affordable, hope you keep this in your mind and make an excellent android course that can be enrolled by even students. Thank you again for your great content; I love you so much.
this jetpack compose thing seems very similar to how react works, even with the possibility of embedding business logic within the UI code via lambdas. but i guess you also offload them into their own dedicated functions when working on bigger projects.
First, there were function and view joined together in code. Then we separate function and view and put view in xml data Afterall we create jetpack compose to join functioncode and viewcode alltogether....😁
Hope these timecodes will help someone 😌

Hey Man,
You doing a great job by providing these aesthetic tutorials free of cost, keep up the good work!
Glad you like them!
Composable is very easy to understand if someone already had played with Dart/Flutter. Thanks for this Crash course!
It also feels almost identical to SwiftUI, but with a few differences in design choices here and there
To the point and no nonsense! I will keep this in my favourite list to revise the course when ever I need. Thank you Philipp!
Man, you've just inspired one more person to get back to his projects. I mean its illegal for recycler view to be so simple. You've got a talent to teach things.
was l am annoyed
😅 I Did it in java and XML. It's painful

Using jetpack after a long time, needed the revision. Your video was a great help as it covers most of the points without wasting any time.
Just brilliant.. Excellent Phillip..I have been using Android XML files all these years.. U explained the basics of Jetpack Compose so well that makes u feel that it's easy, interesting and learnable . Thanks.

My senior recommends your channel for Compose tutorial, and this is just so easy to understand. Much thanks for the tutorial :D
Thank you so much for making this great tutorial!!!

Danke dir, das freut mich!🙌🙏
This new UI way seemed a little mixture of flutter and react and I love this
I am from india and i loved ur content i started ur playlist from basics of kotlin... And ur way of explaning concept is ossum
. thanks for this ossum content .....🔥🔥🔥🔥

Also i like that you share your knowlege with us! Good Job!
as new learner I can say it's one of the best video I found on youtube, thanks philipp
Hi,
I'm a c# programmer (Xamarin)
Was curious about Android programming with Kotlin.
Thanks for your good videos they help me a lot.
No matter how much I thank you, I will never give you the thanks you really deserve, Philip ♥️ You are truly a person of great value to the Android and mobile developer community in general I wish you all the best and give us more ♥️🙏🇪🇬
Great timing! Am actually converting an existing project from flutter to native for better performance and control of device sensors.
Best android introduction, straight to point and gives you idea about how things work ui wise , how ui renders , kind of give beginners like me a starting point to explore. Just want to say thank you very much man, and really appreciate all of your efforts.

This tutorial was just great to get me up and going.
I learned Java and XML in my uni course but I thought it would be better to switch to Kotlin and JetCompose.
Thanks a lot for this man! Its much better than the tutorials on the android website
Adding a Column puts the text into separate rows. Good Job Google. Very intuitive :D
The elements are arranged in a column though. Calling this a row I'd consider the most unintuitive thing ever 😄
This video is very, very clear and easy to follow and understand. I'm very, very thankful for you, it makes me to start get the idea of jetpack compose, and for sure this is the future of Android UI Design
This is exactly what I needed in native Android development! The syntax is so cool and easy to understand if you are familiar with React or Flutter. Much better than XML of course! I think I might go all in native if I continue to use Jetpack Compose!
Thanks a lot Phillip!
yes it's a lot like flutter, which is one of its big advantages, it's just so simple to create layouts this way
Thank you man, you make this community great!
hi from Greece. You were the one who introduced me to xml and now you are the one who introduced me to compose. You explain things very well and the pace is just right. THANK YOU.

It's your the best video!!! And it's the best video in the history of online programming teaching!!!
Haha thank you mate!🙌🙌
Hey, Philipp. Danke dir für all deine tollen Videos!! Du erklärst super gut und hilfst mir so sehr in verschiedene Topics einzusteigen und zu wissen, was man alles können sollte, um eine gute Android Developerin zu werden.
Danke das freut mich 🙌
I can't thank you enough, this is a great crash course for Jetpack compose
The way it works it looks more like imperative than declarative. In declarative style the order usually doesn't matter, and here it does
I am waiting for tutorials like this, thanks 👍
From watching this video i learned a lot about compose. Thanks keep it up
Hands down the best instruction I've seen on jetpack compose. And I've seen tons of vids and scads of websites. Thank you!
Thank you for this! I totally understand how advantageous Compose is compared to the old style. Now it's Compose for me all the way.
Thanks for this video, much valuable as I am entering this Kotlin - jetpack world from Php
Do more compose content, i see a lot of devs struggling with it. And i can totally relate, i'm glad i dived head first when it came out.
Thank you Philipp, this is so amazing tutorial with well summarized version of jetpack compose course. Great Work!!!
I've just started your compose play list. it's good you uploaded it thanks
The Best Android Teacher!
Awesome! So cool! You and Compose is Amazing!
Certainly found it helpful, very clear explanation. A huge thumbsup for the content.
Thank you so much, it really helped me to understand the basics of Jetpack Compose and see the benefits of using it for my current project!
Came here to find out what is jetpack compose. And got the answer, thanks!
Hey Philip,
Amazing job! This is so much better than the official videos provided by Google.
Thank you! Keep it up. :D
Thank you!
Glad i decided to check this video out before trying to learn with XML,
One of the best tutorials for compose beginners
Easy to understand from flutter framework. Thanks a lot.
clear and concise intro to jetpack compose, thank you for sharing :)
Thanks for really well explaining the topic in simple terms!
Compose feels like Flutter which was inspired by React Native which a variation of React which was created a decade ago.
I'm new to Android dev btw😇
Thank you Phillipp for these videos. These are gem.
Insane Video, Thank you very much for the introduction to Jetpack Compose!
Your free content helped me so much! Thanks for everything Philipp.
Amazing tutorial Bro, This introduction was really simple and helpful with clarity Thank you 🙏🙏
i'm not watched fully video but yes i'm 100% sure this is best content. thanks in advance ♥
Thank you!!
Amazing Content Phillip.
Thanks Philipp . You gave a better start to me.
Cool crash course man. No BS. Just to the point.
Thank you Philip for your tutorial, it was very helpful.
Thank you as always Philipp Great job. Very useful
Thanks for this video .I was able to understand it very well .
Nice and Epic video for Jetpack compose learners
This video acctually did teach me a lot, thank you!
stumbled onto this, but it's really great!
Great video. I love this declarative way of UI programming. I did a lot QML before but now I have to switch to Kotlin and was really afraid of diving into XML^^

nice introduction to jetpack compose, thank you
Excellent! Thank you so much this really helped me
Thank you, that helped me to learn the basics
As a React developer, this looks very familiar. Thanks for this
Dude I learn a lot and I think jetpack compose is so much better than xml, specially with recycler view
Thanks for teaching me Compose, Ludwig
PHILLIPP YOU ARE THE MAN
Thank you, this is great to start on jetpack compose
Phillipp, Thanks for your excellent content,
if you make an entire Android course and Upload it to Udemy/TH-cam, which is ok if it is paid course which includes all basics and some projects that help many Android (jetpack) learners, you have a 10 week course on your official site.

Thank you again for your great content; I love you so much.
Thank You, Philipp!
I am sure that Kotlin and Jetpack Compose would never survive without hard work of blogger Phillip Lackner!!!
Love this 😍
Thank you so much, great examples!!
Thank you bro, very succinct and sweet summary
Thank you for the video, much appreciated!!!
Totally awesome! Thank you for this information.
please make videos about jetpack compose more
Coming from iOS development with SwiftUI it’s so funny seeing Google copying Apple. Makes it a lot easier to transition at least. Lol 19:56
this jetpack compose thing seems very similar to how react works, even with the possibility of embedding business logic within the UI code via lambdas. but i guess you also offload them into their own dedicated functions when working on bigger projects.
love this video so much!!!
Thank you Philipp!! :3
Very informative and clear 👍
Thanks for the course!
Hi Phillip, i appreciate your assistance with developers, but please make a video about how to use machine language in android apps
Wtf
@@Rajmanov same reaction lmao
Thank you for this excellent tutorial.
First, there were function and view joined together in code.
Then we separate function and view and put view in xml data
Afterall we create jetpack compose to join functioncode and viewcode alltogether....😁
Thanks man, very helpful
Thanks man, very good content!
Thanks a lot for this video! Its brilliant! So understandable!
The states are kinda similar to React states in web dev
