Let’s build our first Android app – a tip calculator! This video assumes NO prior experience with Android, and by the end you’ll have something an app you could publish. We’ll cover how to create the user interface with XML, and how to code the logic using the Kotlin programming language. These are the fundamental building blocks of any modern Android app.
We’ll use the ConstraintLayout for the layout and two event listeners for the app logic. After you enter a base amount and a tip percentage, the app will calculate the tip and total for you. We also implement a tip percentage animation and a footer to make our app more unique.

Best windows laptop for android studio ,🙏
Woah new course. Nice, much love and support <3
My dream is to be able to study programming and become a professional programmer. But I am currently unemployed and cannot afford to buy a computer for that. If anyone can help me by making a donation of a computer or even an old notebook, I would be very grateful.

Rahul is my go-to teacher for Kothin + Android, thank you!
Anyone knows what shortcut he used to select same attributes from multiple views? 15:21
Thank you! Pls more Kotlin Videos.
Sir please make a java tutorial. Some of us are still using that language. Are there any drawbacks to sticking with it over kotlin for Android development? I was starting to understand oop and I suspect kotlin will need me to understand functional and I just wanna create now not learn
Very easy tutorial. I love this
36:20 – Just a reminder for where i left
I am following rahul on youtube.especially his instagram clone video series is really awesome.
Thank you 🙏 for amazing tutorial ❤️❤️👍 this is my first app 🥳🥳

When trying to upload the release to app console it says "You need to use a different package name because "com.example" is restricted."
Can we expect a video course on Android with backend in (springboot/django/nodejs)
41:32 "So I'm gonna jump to the definition here (using secret hidden keystrokes or some magic click or something)…." HOW? Hovering, left- and right-clicking, get me nowhere in my attempt to see that "Choose Declaration" box with the normal and night themes.
These tutorials are bs for telling they're for beginners. If you're gonna do heavy coding and designing then it's not for beginners or your assumption for beginners is not accurate.
Deeply appreciated!. It is really a perfect tutorial for the kotlin's beginners. I have really enjoyed it.
Do you need a graphics card to run the android emulator?
Thank you. This is the right tutorial for beginners.
You pc is fast! Mine was stuck for 30 minutes and blue screened me lol. I had to use my phone to test the app instead of the in built phone.
Thank you so much though.
Thanks very much for your help with this tutorial Rahul. Much appreciated.
Learning a lot from this, Thanks Rahul! many blessings!
thank you. think i will learn Kotlin to keep my brain active.
12:00 For some reason, after I drag the constraint of the first text box to the top of the screen, setting the top margin to 48 is not working, it's stuck at 0. It will work if I change it in the Code view, but I want it to work in the Design view. Can someone explain why this is happening please?
Thank you! This was an amazing tutorial, this is my very first kotlin Android App!
Good day wishes
Gracias raul
Great video. Thank you for your explanations.
