Handlers and threads

In Android, threading can be performed in the standard way by using threads. It is not recommended to just fire naked threads without any control. So, for this purpose, you can use the ThreadPools and Executor classes.

To demonstrate this, we will update our application. Create a new package called execution with a class called TaskExecutor. Make sure it looks like this:

     package com.journaler.execution 
 
     import java.util.concurrent.BlockingQueue 
     import java.util.concurrent.LinkedBlockingQueue 
     import java.util.concurrent.ThreadPoolExecutor 
     import java.util.concurrent.TimeUnit 
 
     class TaskExecutor private constructor( 
        corePoolSize: Int, 
        maximumPoolSize: Int, 
        workQueue: BlockingQueue<Runnable>? 
 
    ) : ThreadPoolExecutor( 
        corePoolSize, 
        maximumPoolSize, 
        0L, 
        TimeUnit.MILLISECONDS, 
        workQueue 
    ) { 
 
    companion object { 
        fun getInstance(capacity:...
