Below are some best practices to enhance performance when using Coroutines in your Android applications:

  • Use CoroutineScope: Always define a CoroutineScope for your Coroutines to manage their lifetime and ensure they are cancelled appropriately to prevent memory leaks.
  • Dispatchers: Use appropriate Dispatchers to run Coroutines on the main, IO, or Default threads based on the task. Use Dispatchers.IO for network or database operations.
  • Launch vs Async: Use launch for tasks that do not return a result and async for tasks that do return a result. This helps in managing resources effectively.
  • Structured Concurrency: Take advantage of structured concurrency to avoid cancellation leaks and manage hierarchy in coroutine launching.
  • Use Flow for Streaming Data: Use Kotlin Flow for handling streams of data efficiently. It provides cold streams which help in reducing memory consumption.

Here’s an example of a simple Coroutine setup in an Android application:

import kotlinx.coroutines.*
fun fetchData() = runBlocking {
launch(Dispatchers.IO) {
val result = getDataFromApi()
withContext(Dispatchers.Main) {
updateUI(result)
}
}
}
