LoadApp

LoadApp is an Android application that allows users to download files from the internet and view the download status via notifications and a detail screen. It features a custom animated loading button and demonstrates the use of DownloadManager, NotificationManager, and custom views.

Overview

The application provides a simple interface with radio buttons to select one of several predefined files to download. Upon clicking the custom "Download" button, the app initiates a download using the Android DownloadManager. Users are notified when the download completes, and they can click on the notification to view the download details (file name and success/fail status).

Key Features

• Custom Loading Button: A custom View with animated progress and a rotating circle.
• Download Management: Uses DownloadManager for robust background downloads.
• Notifications: Notifies users upon download completion with an action to view details.
• Detail Screen: Displays the name of the downloaded file and its status.
• Modern Android Components: Built using Kotlin, ViewBinding, Navigation Component, and ViewModel.

Requirements

• Android SDK: Min SDK 27, Target SDK 36.
• Language: Kotlin.
• Build System: Gradle with Kotlin DSL.
• Java Version: JDK 11.
• Android Studio: Recommended latest version.
