Can't access onActivityResult zxing for fragment

Question

I'am trying to read the barcode via Zxing in fragment

@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.fragment_caddie, container, false);
    etCodigo = v.findViewById(R.id.etCodigo);
    btnLeerCodigo = v.findViewById(R.id.btnLeerCodigo);

    btnLeerCodigo.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            escanear();
        }
    });
    text = "";

    return v;
}


public void escanear() {

    IntentIntegrator intent = IntentIntegrator.forSupportFragment(FragmentCaddie.this);
    //IntentIntegrator intent = new IntentIntegrator(getActivity());
    intent.setDesiredBarcodeFormats(IntentIntegrator.ALL_CODE_TYPES);
    intent.setPrompt("ESCANEAR CODIGO");
    intent.setCameraId(0);
    intent.setBeepEnabled(false);
    intent.setBarcodeImageEnabled(false);
    intent.initiateScan();

}


 @Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);

    if(result != null) {
        if(result.getContents() == null) {
            Toast.makeText(getContext(), "Cancelaste el escaneo", Toast.LENGTH_SHORT).show();
        } else {
            text = text + " + " +  result.getContents().toString() ;
            etCodigo.setText(text);
            escanear();
        }
    } else {
        super.onActivityResult(requestCode, resultCode, data);
    }
}

The issue is it doesn't access the onActivityResult

What does it mean??? onActivityResult does not return anything? — hamid keyhani, Mar 26 '20 at 00:03
@hamidkeyhani it doesn't access this method a used log.d nothing and yes it doesn't return nothing — Yagami Light, Mar 26 '20 at 00:06
Try onActivityResult on your activity and use log.d then report the result — hamid keyhani, Mar 26 '20 at 00:10

The hosting activity overrides onActivityResult(), but it did not make a call to super.onActivityResult() for unhandled result codes. Apparently, even though the fragment is the one making the startActivityForResult() call, the activity gets the first shot at handling the result. This makes sense when you consider the modularity of fragments. Once I implemented super.onActivityResult() for all unhandled results, the fragment got a shot at handling the result.

The solution was quiet simple the onActivityResult that i implemented was Overrided from the parent activity

The solution is to call the fragment onActivityResult from the parent activity

private static final int BARECODE_REQUEST = 114910;

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {     

    if (requestCode == BARECODE_REQUEST) {
        super.onActivityResult(requestCode,resultCode,data);
    }
}
