Enterprise-grade download manager with automatic HTTP Range resume, local SQLite persistence, lifecycle-aware scopes, disk-efficient streaming, and modern UI integrations for reactive and XML view systems.
ApexFetch is an enterprise-grade download manager for Kotlin Multiplatform (KMP). It is designed to handle large-scale file downloads with built-in local database persistence, automatic resume capabilities, and modern UI support for Android (Jetpack Compose & XML View Systems) and Desktop (Windows & Linux).
ApexFetch is divided into modular components for maximum flexibility:
apexfetch-core — The pure KMP logic core (Ktor, Okio, SQLDelight).apexfetch-compose — UI wrapper for Compose Multiplatform (rememberApexDownload).apexfetch-android-xml — Extensions for Android XML View Systems (LiveData & ViewModel).Ensure your development environment meets the following specifications:
Supported Targets: Android, JVM (Desktop)
Kotlin DSL (settings.gradle.kts)
dependencyResolutionManagement {
repositories {
google()
mavenCentral()
}
}
Groovy (settings.gradle)
dependencyResolutionManagement {
repositories {
google()
mavenCentral()
}
}
Add the required modules to your app or module-level build.gradle.kts or build.gradle:
Kotlin DSL
dependencies {
val apexVersion = "1.0.0"
// Core engine (required)
implementation("io.github.muhamadsyafii:apexfetch-core:$apexVersion")
// For Jetpack Compose / Compose Multiplatform
implementation("io.github.muhamadsyafii:apexfetch-compose:$apexVersion")
// For Android XML (LiveData support)
implementation("io.github.muhamadsyafii:apexfetch-android-xml:$apexVersion")
}
Groovy
dependencies {
def apexVersion = "1.0.0"
// Core engine (required)
implementation "io.github.muhamadsyafii:apexfetch-core:$apexVersion"
// For Jetpack Compose / Compose Multiplatform
implementation "io.github.muhamadsyafii:apexfetch-compose:$apexVersion"
// For Android XML (LiveData support)
implementation "io.github.muhamadsyafii:apexfetch-android-xml:$apexVersion"
}
val fetcher = ApexFetcher(database = mySqlDelightDb)
val download = rememberApexDownload(fetcher, url, path)
Button(onClick = { download.start() }) {
Text("Download Now")
}
if (download.state.value is DownloadState.Downloading) {
val progress = (download.state.value as DownloadState.Downloading).progress
LinearProgressIndicator(progress = progress / 100f)
}
fetcher.downloadAsLiveData(url, path).observe(viewLifecycleOwner) { state ->
when (state) {
is DownloadState.Downloading -> binding.progressBar.progress = state.progress
is DownloadState.Success -> binding.statusText.text = "Completed!"
// Handle other states: Paused, Error, etc.
}
}
