The Android app should at minimum contain a browsable offline map of the local area that displays locations of various emergency-relevant services. It should include automatic bluetooth synchronization to receive stations and other phones.
The code is available on github.
The bluetooth device discovery and connection from Android phones is working, but we're having trouble connecting to python-bluez examples and currently troubleshooting. Could be because python-bluez is unmaintained since 2009 or because the bluetooth usb sticks we have just plain suck.
We'll use a variation on scuttlebutt synchronization that supports receive-only "sync". Currently porting to Java.
There seem to be two Android map libraries:
- MapsForge - Vector-based
- Seems like development stopped in late 2012. Map download server is down. I tried it out and while it's pretty fast even on an older phone, the map is not impressive to look at.
- osmdroid - Bitmap-based
