Android App Development Tutorial for Beginners - Your First App

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.

This video alone had more content and clarity than my 3 weeks' worth of uni lectures. Words cannot describe how thankful I am for this video.

[@storyhearth]

Thanks to this tutorial I have crafted my first ever app on my own! Never worked with Koltin before so that was interesting for sure. I have had ideas of apps to create before but always struggled this was a great call to simplicity and to let the software handle the creating rather than knowing the documentation of every function known to man. Thank you so much.

[@gholamsoori3595]

Deeply appreciated!. It is really a perfect tutorial for the kotlin's beginners. I have really enjoyed it.

[@EnglishRain]

Rahul is my go-to teacher for Kothin + Android, thank you!

[@riju1956]

basically we are just paying to our college for a piece of paper (degree) and learning from utube university

[@cpwithtausif4866]

Lol so true

[@omarelwan5178]

It's bad fact 😓

[@hemantakakati1103]

CS is not just android dev and web dev it is much more deeper than that and thts what we learn in degree

[@bka9705]

sad truth

[@mylifesameme8105]

@@hemantakakati1103 Actually, I'm in university right now for cs and everything I'm learning, you can basically find on the internet or youtube. In fact most of the stuff I learn, I later use youtube or google to help me learn it better. The only thing that school does is it tests your ability on your skills for cs and puts them more on display for you to get good paying jobs. But this can also be done if you're a passionate programmer who puts his own time and effort into creating a portfolio of your own projects and programs that you've built to still getting good paying jobs out there. So you don't necessarily have to go to college or university if you're already a passionate programmer who thinks that you can utilize your time much better on your own in creating a portfolio that is much better than a degree.

For those who got error: Expecting ')' on 27:03 (the 'msg' text appears red), you actually don't need to type the word 'msg' it will automatically appears before the statement. For more explanation, you can go to 31:16 .

[@akeylawhite9217]

Was pulling my hairout on that, thank you!

[@jonathanvillatorocordoba7511]

Thank you! This was an amazing tutorial, this is my very first kotlin Android App!

[@LadyMcN]

It took me a lot longer than I'd like to admit, but I finished creating this app. I chose some different colors for the theme. Now I'm going to try building this out a little bit. Thank you for your work on this tutorial!

[@LadyMcN]

Finished the extensions with some trial and error. Now I want to add an image.

[@LadyMcN]

Finished the app to my satisfaction. It looks a little dopey but I was able to accomplish what I set out to do. Now I'm going through the publishing experience. After that, I'll be designing a new app. So I hope I can find a tutorial or two on app user interfaces and how to make them intuitive and appealing.

[@severussnapeytp715]

​@@LadyMcN Update us when you finish your next project!!

[@dluca182]

I loved this tutorial! Perfect explanation, simple concept, and great for dipping the toes... Android studio is complicated AF thanks a lot!

[@bobbyfried7478]

it's really not. it's just so many parts gives it the illusion of complexity. be calm and you'll see (as i did) it's really user friendly. the software does the heavy lifting.

[@georgiasoftworkssupport5792]

good tutorial. I followed along doing this in java with no problems. It does a good job introducing to android apps as well as starting to use android studio.

[@kristinaloncar778]

A great intro into Kotlin app making. Thank you!

[@blackaamoor]

This tutorial is full of insights and information both for kotlin as a language and android development, i learnt so much and will definitely recommend to other beginners like me. thanks

[@expeknow]

I have learnt soo many things from this course! Please complete the course and by the end, you'll feel like you are completely a new person 💞 just trust the process!

[@SatishMarisetty]

[@davidalex684]

[@silentedict4256]

Thank you! Great tutorial, easy to follow and a great intro to the world of app development.

[@richiembatiah5013]

Thanks so much for the amazing work.🙏💯 please publish more videos on more complex and advanced project with the exact amount of detail including features such as navigation, working with local storage, databases, maps, QR codes, verification codes, in app calls or messages and navbar toggle buttons as well. Would greatly appreciate and contribute to your growth as well.

[@emperordom10]

Great video for first Android project - some coding experience is probably helpful

[@OverrideTips]

You can also reformat (I believe this applys only for eclipse keymap) Ctrl + Shift + f to format all (once all is selected).

Really cool Tutorial.

[@tan8067]

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.

[@bobbyfried7478]

I run Linux and had no issues. it worked great for me.

[@bitancanimation.3153]

Cool tutorial , i would surely try it

Thanks a lot! It was great!

[@yulian5kov]

hey, can u send me the project if you've finished it. I want to see what i do wrong if it's possible. I'm quite a beginner and I'm currently stuck on this line: tvTipPercentLabel.text = "$progress%" the error is: Type mismatch: inferred type is Int but Editable! was expected

[@chadzyhen]

Thanks very useful and well presented it help me a lot.

[@ggipson2]

Thanks!

[@sairishi5024]

I was expecting this

[@cpwithtausif4866]

But I wasn't

[@Sheidraam]

very interesting, thank you!

[@SHIRAZIKHALILOV]

Excellent tutorial.

[@johnxisde]

thanks for that Rahul!

[@drahmedahamed]

Thank you. I followed you and I was able to create a very different app for clinical decision support. Thanks for the insights. Happy to connect on LinkedIn

[@HiNiththila]

Excellent tutorial. Followed instructions to a T, well almost. Just lost the tip evaluator to some corner :)

[@gonzo1457]

Great tutorial!

[@niksatan]

Great tutorial, very helpfull! Would like bigger tut

[@sushilgyawali7880]

Thanks Rahul

[@unprofessional_yuli]

I have no clue what magic is this but it works.

[@MISSWATCHAREETHANAPAIROT]

Thank you!

[@bobbyfried7478]

excellent!!!! thank you for your tutorial. it's a great tool( and i never had to resort to java lol..i've hated java for decades but willing to learn it anyway) i hope this is just a starting point for me. i have some ideas for apps i want to create. probably beyond the scope of this video but a great introduction to Android Studio. i really thought creating an app was beyond me. you have shown just how (believe it or not) actually user friendly it is (if your your willing to learn) and creative you can actually be with this tool. i'm running it on Linux. so surprised by kotlin never knew there were languages i could really dig in and learn. i do know some basic Lua and python, some css, html and such. more a poet than a developer.looking forward to what more lies ahead. headaches and all...lol

[@buiquangminh6697]

hi, can you do a video on android app that has a login/register for example facebook? It loads a login screen with background video and on the screen has section for login and you press login and it does the login process etc?

[@ScamCast]

At 23:43, I didn't realize it was adding the imports when you selected EditText from the dropdown. I manually typed it and was wondering why I was getting errors. Was missing the imports... 😯😯

I have question why not using app inventor? Is it bad to make an app like this one with app inventor? I am really curious
