Java Question onActivityResult: wi is null

[somed3v3loper]

Hi all ,
I am trying to wrap rave on their documentation the result is passed via onactivityresult
I tried both methods described in this thread https://www.b4x.com/android/forum/threads/java-guide-using-onactivityresult.7297/ but could not get the result
I am getting onActivityResult: wi is null

In the calling activity, override the onActivityResult method to receive the payment response as shown below

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
/*
* We advise you to do a further verification of transaction's details on your server to be
* sure everything checks out before providing service or goods.
*/
if (requestCode == RaveConstants.RAVE_REQUEST_CODE && data != null) {
String message = data.getStringExtra("response");
if (resultCode == RavePayActivity.RESULT_SUCCESS) {
Toast.makeText(this, "SUCCESS " + message, Toast.LENGTH_SHORT).show();
}
else if (resultCode == RavePayActivity.RESULT_ERROR) {
Toast.makeText(this, "ERROR " + message, Toast.LENGTH_SHORT).show();
}
else if (resultCode == RavePayActivity.RESULT_CANCELLED) {
Toast.makeText(this, "CANCELLED " + message, Toast.LENGTH_SHORT).show();
}
}
else {
super.onActivityResult(requestCode, resultCode, data);
}
}

                 ion = new IOnActivityResult() {

                @SuppressWarnings("unchecked")
                @Override
                public void ResultArrived(int resultCode, Intent intent) {

                    ba.raiseEvent(ba, eventName + "_resultarrived", true, iw);
                    }
                    //

                
                };
                    try {
                          
                         ba.startActivityForResult(ion, null);
                      } catch (NullPointerException npe) {
                         //required...
                      }
                      BA.Log(BA.ObjectToString(ba));
                      BA.SharedProcessBA sba = ba.sharedProcessBA;
                      try {
                         Field f = BA.SharedProcessBA.class.getDeclaredField("onActivityResultCode");
                         f.setAccessible(true);
                         //BA.Log("sba"+f.getInt(sba));
                        // int requestCode = f.getInt(sba) - 1;
                        
                      } catch (Exception e) {
                         throw new RuntimeException(e);
                      }
                    
                    

        }

    
    }

Uncommenting int requestCode = f.getInt(sba) - 1; resulted in

Don't call f.getInt.

What happens if ion is declared as a static variable:

 private static IOnActivityResult ion;

?

The same result : onActivityResult: wi is null

The same result : onActivityResult: wi is null

Not sure if there is maybe something in this thread that might help....

Might be simpler to implement with JavaObject: https://www.b4x.com/android/forum/t...ivityforresult-with-javaobject.40374/#content

Start with a very simple intent as a test.

This did not work

    Dim i As Intent

    i.Initialize("",  "")
    StartActivityForResult(i)

You are making it difficult to help you. I don't see how the code you posted can work.
