Day 1 of Android Development

 Hello Everyone ,

This is my first day of my android development with kotlin language , There is so many videos course are available on the youtube and paid course are also but i choose google's course that is Android Basics with  Compose in this course there is total 8 units , from basics to intermidiate level i think so , one of the main reason to choose this course is that i have limited time .

Before giving the reason why i had choosen this course let me introduce my self to  you all ,

My name is Sawan kumar , student of class 11th , a IIT JEE aspirant preparing from offline coaching , Many of you will say that you should focus of your studies ,  I think is right i should focus on my studies but like coding every time i just started coding and quit at mid first time just code at last of my class with HTML language now you will say that HTML is not a programming language  i know that this not a programming language this a markup language , then i always searching of best language or fast language etc. then i realise that every programming language has there own use so now decided to learn KOTLIN because google is promoting this language , i thought that i should master this language, i am unable to give more time on because of study and i don't have  personal laptop or desktop because i am not at home , so i just code from my friend's laptop .

I'm unable to code daily but i will try to code .

Today is 14 July , i just cover 67% of Introduction to Kotlin 

In this pathway i learnt

• println
• variables
• data types
• commenting
• functions

for this is enough today from next day i will also mention projects with their code

Project - 1

Gmail has a feature that sends a notification to the user whenever a login attempt is made on a new device.

fun main () {

    val operatingSystem = "Chorme OS"

    val emailId = "sawankumarroy0@gamil.com"

    

    println(displayAlertMessage(operatingSystem, emailId))

}

fun displayAlertMessage(os : String, email : String) : String {

    return "There's a new sign in request on $os for your Google Account $email ."

}

Project - 2

when unknown device will login

fun main () {

    val operatingSystem = "Chorme OS"

    val emailId = "sawankumarroy0@gmail.com"

    

    println(displayAlertMessage(operatingSystem, emailId))

    

    val secondOperatingSystem = "Android"

    val secondEmailId = "sawankumarroy1@gmail.com"

    

    println(displayAlertMessage(secondOperatingSystem,secondEmailId))

    

    val thirdOperatingSystem = "Windows"

    val thirdEmailId = "sample_email@gmail.com"

    

    println(displayAlertMessage(thirdOperatingSystem,thirdEmailId))

    

    val fourthEmailId = "sample_email_2@gmail.com"

    

    println(displayAlertMessage(email = fourthEmailId))

}

fun displayAlertMessage(os : String = "Unkown OS", email : String) : String {

    return "There's a new sign in request on $os for your Google Account $email ."

}

Project - 3 

Pedometer 

fun main() {

    val Steps = 4000

    val caloriesBurned = PEDOMETERstepsTOcalories(Steps);

    println("Walking $Steps steps burns $caloriesBurned calories") 

}

fun PEDOMETERstepsTOcalories(NumberOFStepS: Int): Double {

    val CaloriesBURNEDforEachStep = 0.04

    val TotalCALORIESburned = NumberOFStepS * CaloriesBURNEDforEachStep

    return TotalCALORIESburned

}
