Android App Development Tutorial for Beginners - Your First App
ฝัง
- เผยแพร่เมื่อ 5 ก.ย. 2024
- 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.
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 .
Was pulling my hairout on that, thank you!
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.
I have no clue what magic is this but it works.
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!
android studio's UI is very different now right? i can't find "activity_main.xml" and palette
yo why was I watching the 4 hours course of the same guy, is this what I need as a beginner!
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
basically we are just paying to our college for a piece of paper (degree) and learning from utube university
Lol so true
It's bad fact 😓
CS is not just android dev and web dev it is much more deeper than that and thts what we learn in degree
sad truth
@@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.
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!
Finished the extensions with some trial and error. Now I want to add an image.
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.
@@LadyMcN Update us when you finish your next project!!
You can also reformat (I believe this applys only for eclipse keymap) Ctrl + Shift + f to format all (once all is selected).
Took me two days but i made it! My first app!
Thank you for this clear tutorial
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
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
Hey I know this tutorial is old by now but I just followed along and I just made my first app. Its amazing thank you for this amazing experience!!!
How much time needed?
old? only 2 years old.
Wow I wish someone can teach me
1st part is great. 2nd part is not for beginner programmers. A lot is skipped over and hotkeys are used but not explained. Really frustrating. A lot doesn't work since needed setup is not explained.
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... 😯😯
Rahul is my go-to teacher for Kothin + Android, thank you!
Deeply appreciated!. It is really a perfect tutorial for the kotlin's beginners. I have really enjoyed it.
I'm running into an issue when enterting the bill amount and the app crashes, any idea? I dont see error anywhere.
my Tip is changing with the seekbar.
What would cause this?
There's no activity_main.xml on the new version of Android Stduio :(
Appreciate your efforts and love towards open source and humanity
🙏
Put out more videos like this!!! They help newbies!
I loved this tutorial!
Perfect explanation, simple concept, and great for dipping the toes...
Android studio is complicated AF
thanks a lot!
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.
My guess is this tutorial was done on Android Studio 3.6 (February 2020). That's about thirteen releases ago. Is it possible to release the code to fill in the gaps. There are a few things that are difficult to get right simply following the tutorial. Thanks for a great one.
yeah you're better off finding a new tutorial that uses jetpack compose
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.
I really appreciate the work you all put in order for people to learn
How did you put up the phone and work in it...am developing a tutorial for some Android App and need a similar layout.
Thank you so much Rahul.. It is amazing first experience in development of Android Apps
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.
I run Linux and had no issues. it worked great for me.
Thanks Rahul!!!. First Android app for me created and fully functional.Thank you -
when i create a project, my project don't have activity_main.xml, so i create by myseft. However, it's linearlayout. Could you tell me how to create a constraint layout like video( i use windows)
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?
i have some problem on 18:49 My android studio the option of align dont have a left right edges and the center option how can i let them showing up?
35:40 i didn't face the bug when I click space in the editText , I don't know why
Under 8 minutes for me to subscribe. This is exactly what I needed to get back into android!
i like you man!!!!!
Great video for first Android project - some coding experience is probably helpful
Thank you! This was an amazing tutorial, this is my very first kotlin Android App!
Your Explanation is awesome Sir !
Kindly post link of video or videos of you, so that maximum android development topics will cover ,,
Thank you
Great Tutorial for beginners with clear explanation. Very helpful. Thanks
Kotlin is love! Readability of python with Java's performance.
A great intro into Kotlin app making. Thank you!
Learning a lot from this, Thanks Rahul! many blessings!
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.
For beginners? I was able to follow, but it was too fast.
28:07 Awesome. You show how to debug ☺️
thank you. think i will learn Kotlin to keep my brain active.
Indians are really good at programming,
i'm anxious about my future in career opportunities because it has lots of competition are there in the it sector 😁😁
apne muh miya mitthu !!!!
Is the code for this project available on github? I followed the video and I'm getting an error and neither myself not my mentors know what is wrong. I would like to compare my code to yours so i can see where the mistake is
If i wanted to add multiple screens to this how would I do it ?
Thank you! Great tutorial, easy to follow and a great intro to the world of app development.
This is a real beginner video. Thank you
someone creates an app where you can take photos or videos, the creator can store them somewhere bro pleasee tell me
wish you would announce you keyboard shortcuts as you blaze through steps
Very easy tutorial. I love this
Thank you. This is the right tutorial for beginners.
Extrememly helpful, thank you for teaching me the basics of Android Studio programming!
Thanks for this wonderful presentation. With this simple app as a foundation the limit of what one can do is only your imagination
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?
Resolved, there was a bug in Android Studio | Bumblebee 2021.1.1 Patch 1. Downloaded an older version of Android Studio to fix this
@@sproherty1214 same problem how to fix
Thank you 🙏 for amazing tutorial ❤️❤️👍 this is my first app 🥳🥳
The tutorial is really helpful. I learned a lot. Thanks
Thanks very much for your help with this tutorial Rahul. Much appreciated.

Excellent tutorial. Followed instructions to a T, well almost. Just lost the tip evaluator to some corner :)
Great video. Thank you for your explanations.

Thank you for the nice tutorial brother.
Can we contribute timestamps at all? I keep wishing this video was easier to navigate.
Thank you! Pls more Kotlin Videos.
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.
got the same problem here...have you figured it out? if so can you help 😂thanks
did u get the solution?
@@ninazhang591 did u get the solution?
@@mannatpruthi9065 nope, but I think you can try pressing ctrl. Haven’t tried it on this program but it should make a clickable thingy. Tell me if it works
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
Woah new course. Nice, much love and support

It took me a lot longer than I'd like to admit,
Thanks Carlton drake.
Really cool Tutorial.
Thanks Rahul
