I'm sorry but I don't know what you are doing. What is sibs.b4a.example? Is this your package name?
Why are you using inline Java? It requires Java knowledge.
Yes, "sibs.b4a.example" is my test packagename, defined on "Project / Build Configurations"
And yes I use "inline java" when I need to talk at a lower level with external librarys, mainly for payment machines like myPOS,SaltPay, Portuguese SIBS, Verifone, etc... Each one have a different SDK or library, sometimes .Jar, others .aar, so I use some inlinejava.
And now SIBS use intents and they respond directly to "onActivityResult".
On our Android Studio tests, it works. But our project is made with B4A, so we need to implement it with "inline java", because I think you don't have hooking that call natively on B4A.
That's why we need to access "onActivityResult" from inline java, just like you have done with "_onCreate".
