Val anyMutableList: MutableList = mutableListOf () Val stringMutableList: MutableList = mutableListOf () Val intMutableList: MutableList = mutableListOf () For different data types, or for object types, we’re gonna use Any. We can specify the type of items in the List ( Int, String…). We create a new empty List, MutableList using mutableListOf() method. List & MutableList allows duplicates and null values.List & MutableList are ordered collections in which the insertion order of the items is maintained.MutableList inherites List and supports read/write access, you can add, update or remove items.List is read-only (immutable), you cannot add or update items in the original list.These are some important points you should know before working with Kotlin MutableList: Important points about Kotlin List & MutableList Kotlin Initialize List, MutableList with values.Important points about Kotlin List & MutableList.Both tasks run sequentially within the same coroutine scope. Then, savePosts is called with the posts variable as input to save the posts to the database. In this example, fetchPosts is called first to perform a network request, and the result is saved to the posts variable. Create some background tasks as suspend functions suspend fun doTask1() val myScope = CoroutineScope(Dispatchers.IO)ģ.

This will define the context in which your Coroutines will run. You need to add kotlin coroutines dependencies to your adle app module: implementation ':kotlinx-coroutines-android:1.6.4' implementation ':kotlinx-coroutines-core:1.6.4'Īnd then sync your project, and let’s go. Sequential means that if you have 3 tasks, the first task will run, and the second task will not be executed until the first task is done, and the third task will not be executed until the second task is done, and so on. Hi, it’s Abanoub, and in this article I’m going to show you how to make sequential background tasks with Coroutines using async and await and another method using withContext.
