Offlines

Android app to download CoMaps map files and serve them over the local network — no internet connection needed once maps are downloaded.

Build

cd android
./gradlew assembleDebug

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

Alternatively, open the android/ folder in Android Studio and run.

Usage

1. Download tab — Select a map series, pick the regions you want, tap download
2. Serve tab — Start the server, enter the shown URL (http://<ip>:8080) in CoMaps → Settings → Custom Map Server URL

How it works

• Downloads .mwm map files from the CoMaps CDN
• Runs an embedded HTTP server with Range request support (required by CoMaps)
• Serves files over WiFi — works with any CoMaps app instance on the same network
