TransactionTooLargeException when starting a new action

I thought the optional Intent limit was 1 MB in size, as reported in docs . In any case, I once lost this terrible TransactionTooLargeException:

 E/JavaBinder(368): !!! FAILED BINDER TRANSACTION !!!

The bad thing is that startActivity does not work, but the ActivityManager keeps restarting it again and again, creating endless processes. This seems to be confirmed on this blog, where the author specifies a 'limit' of 86389 characters . My corresponding code snippet is pretty simple:

                    Intent myIntent = new Intent(activity, VacancySwipeActivity.class);
                    //myIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                    Bundle ex = new Bundle();
                    ex.putSerializable(Constants.Extra.VACANCY, vacancies);
                    ex.putString("token", token);
                    ex.putString("cosa", cosa.getText().toString());

                    ex.putInt("dist", searchDistance.getProgress());
                    ex.putString("dove", dove.getText().toString());
                    if (ret.getSearchLocation() != null) {
                        ex.putParcelable("userLoc", ret.getSearchLocation());
                    }
                    ex.putInt("totRows", ret.getTotFound());

                    myIntent.putExtras(ex);
                    activity.startActivity(myIntent);
