Debugging in Android Studio, onKey only runs if I have a breakpoint

Question

I have an issue related to onKey method. When I am debugging with a breakpoint on the first if, the app works correctly, but when I am excuting without the breakpoint, it seems like keycode i (288 - KEYCODE_SCAN_CENTER) is not captured at all. How can i solve this issue?

et_confirmar_caja.setOnKeyListener(new View.OnKeyListener() {
        @Override
        public boolean onKey(View view, int i, KeyEvent keyEvent) {
            if (!TextUtils.isEmpty(et_confirmar_caja.getText().toString()) && keyEvent.getAction()!=KeyEvent.ACTION_DOWN) {
                if(i>=286 && i<=288){
                   if(et_confirmar_caja.getText().toString().equals(tv_caja_inventario.getText().toString())){
                        Tipo_inventario tipo_inventario = new Tipo_inventario();
                        tipo_inventario.execute(str_id_inventario);

                    }else{
                        error.start();
                        final AlertDialog.Builder dialogo = new AlertDialog.Builder(context);
                        dialogo.setCancelable(false);
                        dialogo.setTitle("Titulo");
                        dialogo.setMessage("La ubicacion no corresponde");
                        dialogo.setPositiveButton("Entendido", new DialogInterface.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface dialogInterface, int i) {
                                dialogInterface.cancel();
                                et_confirmar_caja.setText("");
                                et_confirmar_caja.requestFocus();
                            }
                        });
                        dialogo.create();
                        dialogo.show();
                    }
                }
            }
            return false;
        }
    });
