Android Question PLS help me with JavaClass Implementation With OnActivityResult

pls help me about this implementation....
I'll keep it simple and try to be clear. I have 2 Class in .java (ziwiIntegratror and ziwiResponse) and these java files need to implement 'com.google.code.gson:gson:2.8.6' (DONE).
I put exactly these java files between the tags "#if Java #End If" and also I personally modified some parts of the code where I used the lambda function and SO FAR ALL CORRECTLY.....so...I created the function where I recall what I need:

public void TestBluetooth()
{
Activity activity = this;

//Istanzio l'oggetto ziwiIntegrator lanciandolo con il primo metodo costruttore
ziwiIntegrator ziwi = new ziwiIntegrator(activity);
//Chiamo adesso la funzione GetEvaStitch
ziwi.GetEVA_Stitch(0,0,ziwiIntegrator.IRDABOUD_AUTO,true);
}

and in B4A i create the JavaObject and:

Private Sub btnBluethootTest_Click
jo2.RunMethod("TestBluetooth",Null)
End Sub

AND WORK, successfully opens the intent of this ziwi and I can detect
SO THE PROBLEM IS THIS:

in the documentation of these java files i have this function OnActivityResult

@override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
String res="";
ziwiResponse zr=new ziwiResponse();
if (requestCode==0x0000978c){
if (data!=null && data.getStringExtra("ZIWIRESPONSE")!=null){
res=data.getStringExtra("ZIWIRESPONSE");
zr=zr.GetResponse(res);
Log.d("jj","" + res);
Log.d("jj","" + zr.getEVA());
}
}
}


and this obviously allows me to find the result of the Intent opened before and I'm not able to make it work at all

I think I've read all about these Erel examples and applied them too, I've been getting lost in this problem at work for about 2 weeks
Show us what you have done so far, are you getting any errors, what is the problem exactly?

Sure, so, the following java code as I wrote above is all correct, the final result is to open an external intent given by this "ziwiintegrator" library which allows me to detect EVA-DTS data.
the problem is that being an external intent, the latter must return a JSON given as a result and to do so I need an onActivityResult function. I saw that it is not possible to write it of course on the #if java #end if tags and therefore I have to arrange it with B4a.
So, as it should be, I instantiate the ziwi object from the ziwiIntegrator class which executes its GetEVA_Stitch function which in turn starts this intent, to work everything with the OnActivityResult function I take the given result. How do I do this on B4A via the Erel gudia you linked to me?

so pls...in attach i put the documentation

the .pdf documentation you posted does not tell us what you have done so far.

where is the code to StartActivityForResult()? show it. no explanation necessary; just show how you prepare and run StartActivityForResult().
show your code which implements @Erel's example. no explanation necessary; just show what you have done so far with the example.
(note: @Erel's example works very well. it is clear, simple and very well written. i use it all the time without a problem).

it would be helpful if you would show the code within "</>" tags, as previously requested. tap the "</>" icon above and put the code in the dialog.
