Android
As starting point you can use the demo project which can be used from Eclipse or NetBeans via maven command line.
$ git clone git://github.com/graphhopper/graphhopper.git graphhopper
$ # switch to a stable branch like 0.1 - to get your-area.osm see the 'Maps' section below
$ cd graphhopper; git checkout 0.1;
$ ./graphhopper.sh import your-area.osm;And go to the Android SDK Manager and install 2.2 (API 8)
Either via Maven and Command line -> use this for NetBeans
- Download Maven SDK Deployer and execute
mvn install -P 2.2- it uses Android Maven Plugin under the hood where you need to set up ANDROID_HOME - Install Mapsforge in your local repository via the provided script
scripts/maven-install-mapsforge.sh - Now do
./graphhopper.sh android
Or Eclipse
Import Sources as Android project. If you want to customize graphhopper itself do:
cd graphhopper; ./graphhopper.sh eclipse- Refresh your Eclipse project and use it.
Maps
Now that you have a running android app you need to copy somehow the routing and maps data.
- Download the raw openstreetmap file - you'll need that only for the next step to create the routing data
- Execute `./graphhopper.sh import . This creates the routing data
- Download a map e.g. berlin.map
- Copy berlin.map into the created berlin-gh folder
- Optional Compression Step: Bundle a graphhopper zip file via cd berlin-gh;zip -r berlin.ghz *
- Now copy the berlin-gh folder from step 4 (or the .ghz file from step 5) to android /sdcard/graphhopper/maps - e.g. use SSHDroid: scp -P 2222 berlin.ghz root@$URL:/sdcard/graphhopper/maps/
-
For now OSMReader does not work on Android due to some javax.xml dependencies. But you can simply create the graphhopper folder on your desktop and copy them to the Android storage.
