yes im seeing it for the first time

Mam can you provide the ppt of this... So that we can easily read and understand the basic concepts...

It is my two days of attending your class, I am watching your video 1 hour per day. wow I like your free school maam thank you so much

why not this way ? to change the image

class MainActivity : ComponentActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)

val imageArray = arrayOf( R.drawable.imgone,
R.drawable.imgtwo,
R.drawable.imgthree,
R.drawable.imgfour)

val placenames = arrayOf("Taj Mahal", "India Gate", "Gate way of india","Lotus Temple")

var currentindex = 0
var currentindexofplace = 0
val textview = findViewById<TextView>(R.id.nameOfThePlace)
textview.text = placenames[currentindexofplace]
val imageButtonBackward = findViewById<ImageButton>(R.id.imageButtonBackward)
imageButtonBackward.setOnClickListener{
if (currentindex < imageArray.size - 1){
currentindex++
currentindexofplace++
val imagesettter = findViewById<ImageView>(R.id.imgcontainer)
imagesettter.setImageResource(imageArray[currentindex])
textview.text = placenames[currentindexofplace]
}
}
val imageButtonPrevious = findViewById<ImageButton>(R.id.imageButtonPrevious)
imageButtonPrevious.setOnClickListener{
if ( currentindex > 0){
currentindex--
currentindexofplace--
val imagesettter = findViewById<ImageView>(R.id.imgcontainer)
imagesettter.setImageResource(imageArray[currentindex])
textview.text = placenames[currentindexofplace]
}
}
}
}

For the image in same size format use this line of code in each ImageView.....

android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="centerCrop"

Hello mam my android studio facing the AVD problem HAXM file download but AVD not start ....so any solution how to solve this problem

these are very high level reading, let me point some improvements
1. during getter setter , please explain that the get() & set() function right below the value acts as getter setter for that value, or else its confugsing
2. lateinit , was just verbally explain in literal terms, please give real world examples like how helpful it is in dependency injection etc

ComponentActivity() and AppCompatActivity() , by default in android studio it is showing ComponentActivity() function but as both are nearly same , can i start with this function?

I can program VHDL :)

Below the header parameter, the required parameter is not showing. What should I do ? I just simply wrote the q that you've written in your main Activity as well

THANKYOU 😀❤

2x speed 👌

yes

I am working on a plant identification application and I want the users to upload the image of any plant from around the world and in return they will get the information about that plant like, plant name, common names , its uses and characteristics etc. Now anyone please, tell me that which API should I integrate in my FYP ? so that users can get the accurate information. Please tell me as I have a very short time.

Done done mam thank you

Nice ❤

var txtNameofPhoto=findViewById<TextView>(R.id.txtNameofthePlace)
val result = when (currentImage){
0->"Taj Mahal"
1->"Red Fort"
2->"Gateway of India"
3->"Golden Temple"
4->"Lord Ganesha Temple"
else->"Invalid Content"
}
txtNameofPhoto.text=result

In Places app development , The example places i have took in my app.

Thanks

great thank you

kotlin is free or paid?

Thanks for that hard work and a extremely good quality

Theivame 🙏

clear!!

1. Variables and Data Types:
kotlin
Copy code
// Variables
var age: Int = 25
val name: String = "John"

// Data Types
val height: Double = 5.9
val isStudent: Boolean = true
2. Object-Oriented Programming (Classes, Objects, Constructors):
kotlin
Copy code
// Class definition
class Person(var name: String, var age: Int) {
// Constructor

// Member function
fun speak() {
println("Hello, my name is $name and I am $age years old.")
}
}

// Creating an object
val person1 = Person("Alice", 30)

// Accessing properties and calling methods
println(person1.name) // Output: Alice
person1.speak()
3. Control Flow - Decision Making (if-else):
kotlin
Copy code
val number = 15

if (number > 10) {
println("Number is greater than 10.")
} else {
println("Number is not greater than 10.")
}
4. Control Flow - Loops (for, while):
kotlin
Copy code
// For loop
for (i in 1..5) {
println("Count: $i")
}

// While loop
var x = 0
while (x < 5) {
println("Value of x: $x")
x++
}
5. Functions:
kotlin
Copy code
// Function definition
fun greet(name: String): String {
return "Hello, $name!"
}

// Function with default parameter
fun greetWithDefault(name: String = "Guest"): String {
return "Hello, $name!"
}

// Calling functions
val greeting = greet("Alice")
println(greeting) // Output: Hello, Alice!

val defaultGreeting = greetWithDefault()
println(defaultGreeting) // Output: Hello, Guest!
6. Arrays:
kotlin
Copy code
// Array declaration and initialization
val numbers: IntArray = intArrayOf(1, 2, 3, 4, 5)

// Accessing array elements
println("First element: ${numbers[0]}")
println("Array size: ${numbers.size}")

// Iterating through an array
for (number in numbers) {
println("Number: $number")
}

Thanks, now I can put Kotlin in my resume.

XML is old pattern use jetpack compose with features

Mam humare java ka option hi nhi h only for kotlin language hi aa rhi h and hume java use krni h kya koi solution h😢

I think the latest version uses the JetPack Compose to build the UI. I cannot see the XML file the design and no drag and drop menus.

Would be neat if you could mention that you don't start using Android Studio until halfway through the video

hi maam i reached the hello world part but in the emulator, the header is not showing

seeing android studio for the first time

plz continue uploading these gems videos you and your teaching style is awesome
