Notification跳转后回退不会到桌面

    Intent[] makeIntentStack(Context context) {        Intent[] intents = new Intent[2];        intents[0] = Intent.makeRestartActivityTask(new ComponentName(context, aActivity.class));        intents[1] = new Intent(context, bActivity.class);        return intents;    }

        PendingIntent pendingIntent = PendingIntent.getActivities(MyApplication.getContext(),0,makeIntentStack(MyApplication.getContext(),in),PendingIntent.FLAG_CANCEL_CURRENT);

这样，点击notification 会前往bActivity,回退会回退到aActivity。
