B4J Question jGoogleMaps Version 1.82 problem

[Rudolf Messer]

I have used jGoogleMaps Version 1.25 with B4J Version 6.51 successfully for a long time. Now I want to move to the actual B4J Version 8.50 and the actual jGoogleMaps Version 1.82 and get an error. To analyse the problem I have startet the actual GoogleMapsExample and get the same error. After starting the map shows up, but within a second it disappears. After using the "Reset Map"-Button the program terminates.
In the java console I can read:
---
Alert: loadMapLibrary
mapLibraryLoaded!
Alert: !!!mapLibraryLoaded!!!

I used a valid API Key and Java Version 1.8.0_231.

Any Idea to solve the problem?
Thanks,

You should never post questions in the libraries forum.

Note that older versions of jGoogleMaps will not work because Google has changed the API.

Start with this example: https://www.b4x.com/android/forum/threads/jgooglemaps-library.56744/#content
Don't make any change except of changing the API key. Does it work?

The GoogleMapsExample doesn't work ! I used to the actual B4J Version 8.50 and the actual jGoogleMaps Version 1.82 and Java Version 1.8.0_261 and gmap.Initialize2 with my API Key.
The programm windows opens correctly, the map is visible for a second then it disappears, a grey background is shown with the text
"Hoppla! Ein Fehler ist aufgetreten.
Google Maps wurde auf dieser Seite nicht richtig geladen. Technische Details dazu entnimmst du der JavaScript-Konsole."
After pressing the Reset Map Button, the program terminates with

Alert: loadMapLibrary
mapLibraryLoaded!

Thanks for your help,

I've just tried it and it works fine here..

If I set a wrong key I get this message:

I guess that your key is wrong.

 

[Rudolf Messer]

Now it works, thank you very much. The reason was that I have reused the API Key from my Android App development. It is important to get another key by choosing "Map Java Script API".
Unfortunately the map is now covered by the message "For development purposes only". When I try to install the billing, my VISA card is not accepted although I have no problems to buy an app in the Play Store.

You will need to check it with Google.
