Code bugging with "if" condition statement in android

I use if to not to execute some code but that code is executed anyway,even when the condition is saying to not execute.

    private void processImage(FirebaseVisionImage image){
    Log.d("Works122", "esad2123vrth12ing worked2313   "+isDetected);


    if (!isDetected && permitScan){

        Log.d("Works122", "sd12222worked2313     "+isDetected);

        detector.detectInImage(image)
                .addOnSuccessListener(new OnSuccessListener<List<FirebaseVisionBarcode>>() {
                    @Override
                    public void onSuccess(List<FirebaseVisionBarcode> barcodes) {

                        Log.d("Works122", "trembotest     "+isDetected);
                        processResult(barcodes);

                    }
                }).addOnFailureListener(new OnFailureListener() {
            @Override
            public void onFailure(@NonNull Exception e) {

                Log.d("work12", "failure2");

            }
        });

    }else {
        Log.d("Works122", "failuresq1we2");

    }

}


    private void processResult(List<FirebaseVisionBarcode> firebaseVisionBarcodes){

    Log.d("work12", "evrth12ing worsadsadasked2313    "+firebaseVisionBarcodes.size());

    if(firebaseVisionBarcodes.size() > 0){


        isDetected = true;

        FirebaseVisionBarcode item = firebaseVisionBarcodes.get(0);


            Log.d("work12", "evrth12ing worked2313");

            int value_type = item.getValueType();
            switch (value_type) {

                case FirebaseVisionBarcode.TYPE_TEXT:

                    {

                    Log.d("work12", "evrthing worked  "+item.getRawValue());


                    }
                break;

                case FirebaseVisionBarcode.TYPE_WIFI:
                {

                    Log.d("Works122","Wifi "+ isDetected);

                    AlertDialog diaBox = AskOption();
                    diaBox.show();



                }

                default:
                    break;

            }



    }

}

I run this code and the "If" statment is executed even when "isDetected" is true and after some time is not executed anymore,starts working right like it should be.

That's the Log when I run:

  true***

Look even with the variable being "true" the code still runs for a while and I don't know why.
