How to implement a thread pool for executing tasks in your application?

To implement a thread pool in an Android application, you can use the ThreadPoolExecutor class from Java or Kotlin.

Example in Kotlin using Executors.newFixedThreadPool:

import java.util.concurrent.Executors

// Create a pool of 4 threads
val threadPool = Executors.newFixedThreadPool(4)

// Submit tasks for execution
threadPool.execute {
    // Task 1 code
    println("Task 1 is running in thread ${Thread.currentThread().name}")
}

threadPool.execute {
    // Task 2 code
    println("Task 2 is running in thread ${Thread.currentThread().name}")
}

// After completing the work, properly shut down the pool
threadPool.shutdown()

If you are using Kotlin Coroutines, you can use Dispatchers.IO or create your own thread pool via newFixedThreadPoolContext.

A thread pool limits the number of threads running simultaneously, which helps efficiently utilize resources and avoid creating too many threads.
