AlertDialog Multiple Choice The AlertDialog is a subclass of Dialog that can display buttons, a simple text message, a list of items, single-choice items, multiple-choice items, etc. Developers can display a more complex View on the alert dialog window using a custom View. The following android application development tutorial will demonstrate to us how we can display a list of multiple choice items in the alert dialog window as the content. And how developers can be notified when users select items from the multiple choice items list via the supplied listener. Android developers can add a click listener for the alert dialog multiple choice list items. To create an alert dialog developers have to initialize an instance of AlertDialog.Builder object. This AlertDialog Builder object can define the alert dialog’s various properties such as button, message, icon, list and etc. Finally, they can create an AlertDialog using this builder instance. ...

Introduction This code demonstrates how to request permissions at runtime in an Android application written in Kotlin. The Android operating system introduced runtime permissions in Android Marshmallow (API level 23). This means apps no longer get granted all permissions they declare in the manifest file at install time. Instead, the app must explicitly request permissions from the user when it needs to access sensitive features or data on the device. Breakdown of the Code The code consists of three main parts: MainActivity.kt: This file contains the main activity class for the application. It defines a button that the user can click to initiate the permission request process. It also handles the result of the permission request. ManagePermissions.kt: This file defines a separate class called ManagePermissions that encapsulates the logic for checking permissions, requesting permissions, and processing the permission request result. This class promotes better code orga...
