the thing I liked about this video is that's a very quick demonstration about Android app development, Maybe it's a very silly app you've created after all, But at least you've spared me watching hours of very detailed tutorials and trying to absorb information that I don't need to know right now to eventually build the very same silly app. Any way I wish there is a lot of videos like this kind of video that we can call it " A very quick demonstration of... ", Videos that show you abilities of cretin technology or programing language or a frame work, And let you decide if that is the right thing for you to learn or else.Thank you.

2 seconds in ... "i'll get it"

5 mins later... "off to watching some cats videos"

I have been trying to find a tutorial like this for months now. I hope that you keep this up and also build more upon what the code does rather than how the IDE works.

Hi Gary,
Thanks so much for sharing! I love coding and have finished your tutorial.
There's been some updates, so to help others, things to be aware of:
1. Set the minimum SDK to API 14 while making the project. The others have a crazy folder structure and don't match the video.
2. Make sure language is set to Java. KT doesn't work with the code Gary has written. "Void" will not be recognised and so on.
3. While setting up the display set the constraints by clicking the arrows on the right hand palette window. This lets the app know the position of the text "Hello World" in relation to the button.
4. There was only one string named in the string folder under resources. Don't worry just copy it and change app_name to Tap_Me and My Application to Tap Me. When your in the layout screen click the button then find the text box under common attributes, after typing the @ symbol your tap_me variable should show.
5. When running the emulator make sure you have 7GB on your local drive (C:\) even if the studio program installed somewhere else otherwise you'll get: "The emulator process for AVD Nexus_5_API_30 was killed"

6:20 thanks for telling me to put coffee into my computer. It doesn't work anymore. Thanks again

Just what I needed, having to use this IDE for part of my A-Level Computer Science project, and this tutorial was very helpful to get me started with it! (Only problem is that you didn't use the dark theme!)
Thank you very much!

Today, I wrote my first Android app. I wrote it with the latest Android SDK. Some of the layouts were different, but I figured it out.
The steepest of learning curves usually involve the boilerplate aspects of development. I have no trouble with coding. I've been doing it for decades. I was even coding Java professionally five years ago. But getting past that entry point for a new environment or platform is often the stickiest bit. This video was exactly what I needed to get my first Android app running. Thanks!!

I really love your videos. Either they make me think and/or simplify something that I find confusing.

Keep up the great work!

I am a chemical engineer and a data scientist that wish to learn to code to make my own app in android. I am good at excel macro VBA but has 0 knowledge and experience on java. I really love this short tutorial you guys made, very easy to follow and i could copy with the same result. You got me subscribed to your channel. Please continue with this series of video.

thanks,
MH

I thought I would never say this but I wish this video had been published earlier, it would have made at least my life easier

I am an old programmer, but just now looking for a way to make phone apps. This will get me started. I subscribed. I like the way you pack a lot of information in a short time. Excellent video!

You're the smartest android authority guy!!! Great video!

[getman]

You are the real teacher of Android..please don't stop this Awesome .

[realRichHunting]

Sweet! Thanks for the lessons! I am really enjoying working in Android. :)

For the beginners those who really have any clue about android this video is just perfect and he explains from scratch everything so simply you will understand everything. Nice work. The example is very basic very simple and for beginners so nothing great we should expect as it is meant to be simpler for people like me who are clueless about android!

[srceko]

Great intro to Android programming. I'd be very happy to see more videos like this. Maybe the whole Android programming series wouldn't be bad idea. Thanks!

Commandable effort from all those whom made this video possible.
Its one of the most easy, short & simple clip that clearly tailored for basic beginners. Cannot wait till next video, Thanks .
