B4J Question Google Maps - Correct Map Service

[barry davis]

I have used google maps using B4a and b4i for years, and have not had major issues. But every time i try and use it with B4j, I do not get very far. I assume i need a specific key for B4j. Having said that, I am not sure which Google Map services i need to request. There are services for android and ios, but i assume these will not work for B4J

I loaded the two map demos from the web and get the same result. It never comes back to gmap ready. i assume its the google key. I turned the firewall off just in case, but no change.

Can u point me to the reference that says which google map service i should request.

Thanks in advance,
Barry

Yes, Your google key is probably invalid if gmap ready does not fire. Though you should get a message on the screen if the API key is invalid.
You are using Java19, right?

i am using C:\Program Files\Java\jdk-14.0.1\bin\javac.exe, per the B4J installation instructions page. I assume that is the latest version.

It is the wrong version... JGoogleMaps required Java 19.
See

jGoogleMaps library

This library is similar to B4A and B4i GoogleMaps libraries. 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...

VERY IMPORTANT NOTE on this page:

Under the hood it uses JavaFX WebView with GoogleMaps JavaScript API V3. <- this is the Api you need to configure in google....

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

No, you have to use Java19 just for this version of Google Maps - not necessary for other B4J apps. Refer to the info that @DonManfred has in his post.

You don't need to uninstall Java 14. Just install 19 from the link above and add the following reference to your Project Attributes:

#JavaCompilerPath: 19, C:\java19\jdk-19.0.2\bin\javac.exe

(or whatever your path is)
