Android | How to know the source code branch against the snapshot build

Open Source Routing Engine Mobile
1

Hi all,
I’m stuck in this issue for quite some time now. I have created routing data from 0.8 branch of source code and I’m getting this exception
java.lang.IllegalStateException: Version of nodes unsupported: 3, expected:5. Make sure you are using the same GraphHopper version for reading the files that was used for creating them. See https://discuss.graphhopper.com/t/722

In my app/build.gradle I have tried 0.8-SNAPSHOT and 0.9-SNAPSHOT but no luck. Please guide how to know the exact source code branch against the snapshot we are using so I can create the route date with correct version.

implementation(group: ‘com.graphhopper’, name: ‘graphhopper-core’, version: ‘0.8-SNAPSHOT’) {
exclude group: ‘com.google.protobuf’, module: ‘protobuf-java’
exclude group: ‘org.openstreetmap.osmosis’, module: ‘osmosis-osm-binary’
exclude group: ‘org.apache.xmlgraphics’, module: ‘xmlgraphics-commons’
}

It’s exactly as it says. You need to clear the cache and recreate the road network files from your pbf.
You can do this manually or through code.

@Gregws Thanks for the reply. You mean, clear cache of my Android Studio (Invaliate and restart)? BTW this is my project level gradle
allprojects {
repositories {
jcenter()
google()
maven { url “https://oss.sonatype.org/content/groups/public/” }
}

I have even tried this
maven { url “https://oss.sonatype.org/content/repositories/snapshots/” }

I’m not sure if this is important. I’m using ubuntu, this command was failing

./graphhopper.sh -a import -i slovenia-latest.osm.pbf

using java (64bit) from

./graphhopper.sh: line 185: [: ==: unary operator expected
./graphhopper.sh: line 85: mvn: command not found

existing jar found tools/target/graphhopper-tools-0.8.2-jar-with-dependencies.jar

now -a. JAVA_OPTS=-Xmx1000m -Xms1000m -server

so i used this one and it successfully created the route data

./graphhopper.sh import slovenia-latest.osm.pbf

using java (64bit) from

using existing osm file slovenia-latest.osm.pbf

./graphhopper.sh: line 85: mvn: command not found

existing jar found tools/target/graphhopper-tools-0.8.2-jar-with-dependencies.jar

now import. JAVA_OPTS=-Xmx1000m -Xms1000m -server

Clearing the cache of Android Studio and rebuilding route data using ./graphhopper.sh import slovenia-latest.osm.pbf this solve the problem.
@karussell @devemux86 any idea guys? I’m already spent last night trying to figure out but no luck. Please help

Hey,
We are using different platforms but it should be similar. I mean clearing the graph cache.
I’m not an expert in all applications of graphhopper and I can only speak to my experiences.

eg.
GraphHopper graphHopper = new GraphHopper().setGraphHopperLocation(LocationGraphhopperFiles) // “gh-car”
.setEncodingManager(new EncodingManager(“car”))
.setOSMFile(LocationRoutingFile)
.forDesktop();

LocationGraphhopperFiles = graph cache location
LocationRoutingFile = pbf location

Navigating to the cache location I have;

If I manually delete those then it rebuilds the cache on run.

Alternatively you can clean the cache through code;
GraphHopper graphHopper = new GraphHopper().setGraphHopperLocation(LocationGraphhopperFiles).forDesktop();
graphHopper.clean();
graphHopper.close();

graphHopper.importOrLoad(); will either load the existing cached files or import new ones (or the other way around)

You are manually creating the graph cache I presume and the differences in versions is causing the error. I found it easier to allow the graphhopper dependency to create its own.

You are genius. Why it didn’t come to my mind lol. I was trying all the different things but forgot that the graph data is not going to be copy every time. Thank you very much Gregws.

Glad to have been able to help you.
I had the same issue at one point :slight_smile:

Same issue, ( Android) This is a fresh build with fresh .pbf and map files
An error happened while creating graph:Version of edges unsupported: 14, expected:15. Make sure you are using the same GraphHopper version for reading the files that was used for creating them.

As per gregws advice above I deleted all the graph files ( on the phones “Internal storage\Download\graphhopper\maps\new-zealand-latest-gh” directory, except for the map

This produced: , "An error happened while creating graph:Cannot load properties to fetch EncodingManager configuration at: /storage/emulated/0/Download/graphhopper/maps/new-zealand-latest-gh/

So I reinstated the properties file, so just the properties file and the map in the directory I get the old error mesage back again
