kotlin android project

00:00:02

will learn how to program an Android

00:00:03

application based on the cotlin language. During the

00:00:06

course, we will get acquainted with the Kotlin language in

00:00:08

Android Studio, we will develop several

00:00:10

projects and study all the intricacies of

00:00:12

building Android applications. But

00:00:14

before we start creating projects,

00:00:16

let's talk a little about ourselves language,

00:00:18

its capabilities and also learn a little

00:00:20

more information about Android Studio. Until

00:00:24

recently, the only and correct

00:00:25

solution for developing projects from Android

00:00:28

was the Java language; it allowed you to write the

00:00:30

entire functional part of the application and

00:00:33

had excellent support in the

00:00:34

Android Studio program; later,

00:00:37

new programming languages began to appear on the market

00:00:39

that offered the possibility of

00:00:40

developing Android applications easier and

00:00:43

faster. The problem with the Java language was

00:00:45

that it is a fairly old

00:00:48

programming language and, due to its

00:00:50

age, many of its concepts and the

00:00:52

coding format itself are already outdated. New

00:00:55

languages offer a more simplified format for

00:00:57

writing code, while taking into account the same

00:01:00

number of functions and capabilities that

00:01:02

were in the Java language, it is worth noting that

00:01:04

in addition to Kotlin, Java was replaced by

00:01:07

such technologies as flutter reac for all of these

00:01:09

Sharp Samarin and many other

00:01:11

technologies By the way, if you are interested in learning

00:01:14

more about these technologies, then courses on

00:01:16

all these topics will be presented on the

00:01:18

website it-proger.com I will leave links to these courses

00:01:20

in the description of this video, the

00:01:23

Kotlin language was developed as an alternative to the

00:01:25

Java language, the language has a lightweight

00:01:28

syntax compared to Java and can

00:01:30

perform similar functions and actions that

00:01:32

its older brother Kotlin first

00:01:35

officially appeared in 2016 Although its

00:01:38

development has been going on since 2010, a

00:01:41

year after its release in 2017,

00:01:44

Google announced that it now provides the

00:01:46

ability to develop Android programs

00:01:48

based on the Kotling language and that

00:01:50

this language is now included by default in the

00:01:52

standard build of Android Studio

00:01:54

programs that are created for the development of

00:01:55

all Android applications two

00:01:58

years later in 2019, last year Google

00:02:01

announced that developing programs in

00:02:03

Kotling is now more

00:02:04

preferable than developing in

00:02:06

Java; the big advantage of the Kotling language

00:02:09

is its simplicity and easy

00:02:11

integration into other Java projects. You

00:02:13

can open any Java program and

00:02:15

create a new one with it. file that

00:02:17

Kotlin will be written and everything will interact with each

00:02:20

other correctly and no

00:02:21

errors will be issued. If you have already

00:02:24

started to worry about the good old

00:02:26

Java language, then I can immediately reassure you that the

00:02:28

Java language is already morally outdated. But

00:02:31

it still won’t disappear anywhere.

00:02:33

firstly, the language is still used

00:02:35

in hundreds of thousands of different programs and the

00:02:38

Java language will still be used to support them; secondly, the

00:02:41

Kotling language, like many other new

00:02:43

technologies, uses the Java

00:02:45

Virtual Machine platform; this platform is written

00:02:47

in Java and so that languages such as Kotlin and

00:02:50

others could work, it is necessary to

00:02:51

support the platform itself, it turns out to be

00:02:53

a kind of vicious circle in which Java

00:02:56

feels very confident in the future

00:02:58

for Android projects. You can safely

00:03:00

use the Kotlin language or the Java language. In

00:03:03

fact, you won’t feel much of a difference; the

00:03:05

point will be that only the

00:03:07

writing syntax code for Activity It

00:03:10

will be slightly different And if we are

00:03:12

talking about Kotlin, then the syntax will be

00:03:14

lightweight and simplified in comparison with the

00:03:17

Java language, at the same time, everything that you

00:03:19

could previously learn or see in the

00:03:21

Java language in relation to Android is applicable

00:03:24

to the Kotlin language, for example, you want create a

00:03:26

pop-up window Okay, then we use the

00:03:28

toast class as it was in the Java language for

00:03:31

Android projects. If you want to go to

00:03:33

another page in the application, in this

00:03:35

case the same intent class is used

00:03:37

as was previously in Java, that is, it is important

00:03:39

to understand that Kotlin is nothing more than

00:03:42

just a lightweight in terms of syntax,

00:03:44

the language based on it, you prescribe the same

00:03:47

concepts that were in the Java language, but

00:03:49

make them simpler and faster, the Kotlin language does

00:03:52

not pretend to be a complete replacement for the

00:03:54

Java language, it is only an

00:03:56

alternative For faster

00:03:58

code writing since Kotlin

00:04:00

is an alternative language

00:04:02

Java, then it has all the same constructs

00:04:05

that were in Java, but they are

00:04:07

written a little using a different

00:04:08

syntax, so before studying the course,

00:04:11

I recommend that you familiarize yourself a little with

00:04:13

Android Studio, courses on Android Studio are

00:04:15

available on our website itproger.com during

00:04:18

this course You will learn to develop

00:04:20

projects for Android using the

00:04:22

Kotlin language. You will develop a to-

00:04:24

do list project and also build a full-fledged

00:04:27

application store, a registration and

00:04:30

authorization system, as well as with goods inside the

00:04:32

application. By the end of the course, you will have

00:04:34

good knowledge of working with Android

00:04:36

Studio and the cotlin programming language,

00:04:38

by the way, all this course will also be

00:04:40

presented on the website it-proger.com, where

00:04:43

you will also find the homework code and

00:04:45

a lot of other useful information,

00:04:47

I will leave a link to the course in the description of this

00:04:49

video in addition. In this lesson we

00:04:52

will download Android Studio and also

00:04:54

create a new project specifically for based on the

00:04:56

Kotlin language, in order to download

00:04:58

Android Studio, you need to go to their

00:05:00

official website, I’ll leave a link to it

00:05:02

in the description of this video, and here you

00:05:05

download the

00:05:06

Android Studio program itself. And after installing it, like the

00:05:09

most ordinary program, there are no

00:05:11

pitfalls here, just

00:05:12

follow standard installation after

00:05:15

installing the program The first thing I

00:05:17

suggest doing is making sure

00:05:18

that Kotlin is correctly connected

00:05:21

to Android Studio, for this you can go

00:05:23

to the plugins tab. Here you can

00:05:25

register Kotlin and if you don’t

00:05:28

have a plugin here that is simply

00:05:29

called Kotlin then Most likely you

00:05:31

already have it installed and you can

00:05:34

find it on the install tab. You see,

00:05:36

here I have this plugin already

00:05:38

installed. Well, you just make sure

00:05:40

that you also have an

00:05:42

additional checkmark here, then

00:05:44

you can connect Kotlin all this

00:05:46

language for your Android projects Now

00:05:49

let's create a new project for this,

00:05:51

go to the Project tab, here

00:05:53

we click New Project, a

00:05:56

new tab will open, we will stretch it a little and in

00:05:59

this one we now need to select a template for

00:06:01

our future application. I

00:06:03

select mtviews as a template Activity Well,

00:06:06

I click Next next I need to indicate

00:06:08

the name for my project Let's My

00:06:11

project it will be called Well, let's say in the

00:06:13

following format it is it-proger App,

00:06:15

the package is indicated here, I

00:06:17

will not change it, the location

00:06:20

of the project is indicated, the language of the project is indicated,

00:06:22

select Kotlin Well and I won’t

00:06:25

add anything else here, at least we don’t change the sdk

00:06:27

and I can just click on Finish to

00:06:29

create our empty template

00:06:31

project. After creating the project, you

00:06:33

will notice that the most

00:06:35

standard Android Studio project will open in the

00:06:37

side part, here

00:06:39

all the files of your project will be presented in full. In the

00:06:42

central part two files will be opened,

00:06:44

this is an xml file with the design of your

00:06:47

main page and also a file with the

00:06:49

extension this is a file Where you will

00:06:52

describe all the functionality for your

00:06:54

main page and all this functionality

00:06:56

will be described on the basis of a language such

00:06:58

as Kotlin Well, starting from the

00:07:01

next lesson we Let's start

00:07:02

developing various Android applications

00:07:04

based on the Kotlin language. In the same lesson, we

00:07:07

just created the project itself. We

00:07:09

learned a little about Kotlin and Android Studio. Well,

00:07:12

starting from the next lesson, we will begin the

00:07:14

practical part of implementing

00:07:15

various Android applications. Well, what do

00:07:18

I have on this? everyone I hope you liked the lesson

00:07:19

we will see you in the

00:07:21

future See you soon
