Java novice and Delphi firefox

[Chester Wilson 5]

Delphi 10.3, firemonkey. Need to learn how to write Delphi Firefox routines that call or are called (back) by various Java/Android routines.

Please tell me where to find code examples for firemonkey delphi gnss with java things and loopers and callbacks and things.

Firefox? I assume Firemonkey.

You are more likely to get help if you are specific with regards to what you want to do.

True, Lars.  Sorry.  It's been one of those months!

I have tried to edit it, but have not managed to find out how.

Any ideas where to find the information requested please?
