Offline Maps & Apps

Share files and serve offline CoMaps maps over your local network.

Features

• Download maps — Select map regions from CoMaps CDN and download them for offline use
• Serve maps — Run an HTTP server with Range-request support so CoMaps can load maps over WiFi
• Share apps — Add F-Droid or GitHub app URLs to download and serve APKs to devices on your LAN
• Import files — Import any file from device storage and share it over the network
• No internet needed after initial setup — everything runs over local WiFi

Build

cd android
./gradlew assembleDebug

APK at app/build/outputs/apk/debug/app-debug.apk.

Usage

1. Download tab — Pick a map series and regions, download them
2. Serve tab — Start the server, enter http://<ip>:8080 in CoMaps or any browser
3. Settings — Add app URLs (F-Droid/GitHub) or import files from storage to share them

How it works

• Downloads .mwm map files from the CoMaps CDN
• Downloads APKs from F-Droid API or GitHub releases
• Stores imported files directly in the shared directory
• Runs an embedded HTTP server with Range request support (required by CoMaps)
• Serves files over WiFi — works with any device on the same network
