This library is similar to B4A and B4i GoogleMaps libraries.

SS-2015-07-30_15.35.52.jpg


It is based on this open source project: https://github.com/dlsc-software-consulting-gmbh/GMapsFX/ (Apache 2 license).
Under the hood it uses JavaFX WebView with GoogleMaps JavaScript API V3.

Using the map is quite simple. You need to initialize GoogleMap and then wait for the Ready event.
GoogleMap.AsPane returns the pane that holds the map. You should add this pane to the nodes tree.

Once the ready event is fired you can add markers or change the position.

Updates:

V2.00 - Depends on OpenJDK 19. Previous versions will not work.

1. OpenJDK 19.0.2 + OpenJFX 17.0.6: https://www.b4x.com/b4j/files/jdk-19.0.2.7z
2. Add to main module:
B4X:
#PackagerProperty: IncludedModules = javafx.web
#PackagerProperty: AdditionalModuleInfoString = exports com.lynden.gmapsfx;    exports com.lynden.gmapsfx.javascript;    exports com.lynden.gmapsfx.javascript.event;
#PackagerProperty: AdditionalModuleInfoString = exports com.lynden.gmapsfx.javascript.object;    exports com.lynden.gmapsfx.service.directions;    exports com.lynden.gmapsfx.service.elevation;  
#PackagerProperty: AdditionalModuleInfoString = exports com.lynden.gmapsfx.service.geocoding;    exports com.lynden.gmapsfx.shapes;    exports com.lynden.gmapsfx.zoom;
3. Add reference to jOkHttpUtils2.

Tip: to fix logging encoding issues with Java 19+, add this:
B4X:
#VirtualMachineArgs: -Dfile.encoding=UTF-8 -Dsun.stdout.encoding=UTF-8 -Dsun.stderr.encoding=UTF-8
#PackagerProperty: VMArgs = -Dfile.encoding=UTF-8 -Dsun.stdout.encoding=UTF-8 -Dsun.stderr.encoding=UTF-8

The standalone package will not work without steps 2 and 3.

I remember similar problems when the API_KEY was wrong or undeclared. Did you check it ?
