Asynchronous programming is a form of programming that allows a program to continue running without waiting for a particular event to finish. This can be useful when dealing with events that take a long time to complete, such as network requests.
Coroutines are a type of asynchronous programming that can be used in Kotlin. They are lightweight threads that can be used to run code in the background without blocking the main thread.
Coroutines can be used to write asynchronous and non-blocking code. They are often used for tasks such as network requests, database operations, and UI updates.
A coroutine can be created using the launch
function. This function takes a suspend
lambda as an argument. The suspend
keyword is used to mark a function as being able to be suspended.
launch {
// code to be run in the background
}
A coroutine can be suspended using the suspend
keyword. This keyword can be used to mark a function as being able to be suspended. A suspended function can be resumed at a later time.
suspend fun doSomething() {
// code to be run in the background
}
A coroutine can be resumed using the resume
function. This function takes a suspend
lambda as an argument. The suspend
keyword is used to mark a function as being able to be resumed.
resume {
// code to be run in the background
}
A coroutine can be cancelled using the cancel
function. This function takes a suspend
lambda as an argument. The suspend
keyword is used to mark a function as being able to be cancelled.
cancel {
// code to be run in the background
}
Coroutines can be used to update the UI without blocking the main thread. This can be done using the withContext
function. This function takes a suspend
lambda as an argument. The suspend
keyword is used to mark a function as being able to be suspended.
withContext {
// code to be run in the background
}
