I have custom build graph files that were built with core version 0.12.
In my MainActivity I want to load these files as following:
void loadGraphStorage() {
logUser("loading graph (" + Constants.VERSION + ") ... ");
new GHAsyncTask<Void, Void, Path>() {
protected Path saveDoInBackground(Void... v) {
GraphHopper tmph = new GraphHopper().forMobile();
tmph.load((mapsFolder.getAbsolutePath()));
log("found graph " + hopper.getGraphHopperStorage().toString() + ", nodes:" + hopper.getGraphHopperStorage().getNodes());
hopper = tmph;
return null;
}
protected void onPostExecute(Path o) {
if (hasError()) {
logUser("An error happened while creating graph:"
+ getErrorMessage());
} else {
logUser("Finished loading graph. Long press to define where to start and end the route.");
}
finishPrepare();
}
}.execute();
}
and I receive this log:
/com.graphhopper.android I/GH: An error happened while creating graph:No virtual method position(I)Ljava/nio/ByteBuffer; in class Ljava/nio/ByteBuffer; or its super classes (declaration of ‘java.nio.ByteBuffer’ appears in /system/framework/core-oj.jar
Prepare finished but hopper not ready. This happens when there was an error while loading the files
I read that these errors concerning ByteBuffer classes could occure upon a JDK incompatibility?
im running:
Android 8.1 API 27
and Android Studio
JAVA_VERSION=“1.8.0_152”
OS_NAME=“Darwin”
OS_VERSION=“11.2”
OS_ARCH=“x86_64”
SOURCE=“”
can anybody help me out?
