Make Your First Simple Android App with Kotlin (Android Kotlin Tutorial for Beginners)

In this tutorial you will learn how to make android apps in Kotlin.

Kotlin is a new official language for Android development. It's certainly a step towards safer, readable and quicker to write code.

Kotlin supports properties, you don't have to call "findViewById()", and it also tries to get rid of the dreaded null reference exception.

Whether you are a complete beginner who is just starting out in Android app development or you are a Java Android developer looking for something new, you cannot go wrong with Kotlin in Android.

Thank you for this tutorial! So many videos are aimed at people with absolutely zero development experience, which is very frustrating as they often go way too slow. I'm new to mobile development, but I have a fair amount of programming experience, so this video is just about the right pace for me.

Too fast for a beginner. Not enough details described. Basically this tutorial is "write down what I write and hurry the hell up" .

[TheDuckPox]

Too quick. Not used to either xml, java, or kotlin.

I just made it 2 years after the creation of this tutorial and though versions changed since then, it worked like a charm. I am an absolute beginner in Android development and Kotlin (just completed two Linkedin courses), but i could follow it easily. In two or three cases I checked the Android development documentation so that I really understand what is going on, but that's all. It was very usefull as we had started from scratch and used even some advanced features as lambda functions.

Thanks very much!

Please do a full kotlin programming tutorial.

Need to watch these videos in 0.5X speed, mans is motoring through everything, what the heck

[trentguillory]

Great video. Perfect speed for me. I'm coming from iOS so I do have some background on how mobile dev works in general. I could see how a complete beginner might be lost though.

[manuelos]

it sounds like a tts talking but also like a human
your voice is in between them

[seanotoole]

Very informative, I've only just learned the fundamentals of kotlin, watching a few videos just to see code being written, as I know variables, arrays, boolean ect ect but writing code is quite daunting 😄👌

[electrictrooper]

Even coming from web development with HTML, CSS and Javascript, this tutorial was a little fast to follow as it was my first time developing in such an unfamiliar environment. You may want to break down the key components and tools of Android Studio first before diving into the tutorial.

[Hartofylax]

It is a fast tutorial but if you change the speed to 75.0 or 50.0
It is much easier
Also this version works on the latest android studio versions like 3.6

[muralidharanv.s]

Nicely explained. was able to get it going in about half hour. Thanks so much. Looking to more

[JeepDude]

the val you create initialTextViewY is not a call in my version, the latest version as of 1/5/20. Where is there documentation to look stuff up like this, and don't say Google, 'cause I did that... but for real?

[ChimmieSam]

I also added a ValueAnimator so the textView counts down as it flips:

->
//creates a animator object that decreases number
val animator = ValueAnimator.ofInt(seekBar.progress, 0)
animator.setDuration(1000)
animator.addUpdateListener {

}
animator.start()


seekBar.progress=0
}

The pace is super sonic style. please slow down if its for beginners

[AnthonyPrechtl]

I want my find view by id back and I want to type it every time.

[iZoom-xoeb]

Thanks for the hand-on video.
Just mark it the day I "built" my firs Mobil app ：-）

[sebastianfrai]

I can'T run app luncher in android studio. What missing from my instalation?

[vaibhavjadhav]

Really nice app for beginner and for me also. All the best

[volimpia]

This is completely not for beginner in kotlin. I am coming from ios and only because of that got most, but still there were parts that were unfamiliar. No explanations are given, in fact why touch animations at all for the first app? or methods. with no explanations.
