Answer 1

你应该尝试设置

notification.defaults = Notification.DEFAULT_SOUND | Notification.DEFAULT_LIGHTS;

或明确设置：

notification.sound = 
    RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

Answer 2

不确定你是否解决了这个问题，但我遇到了同样的问题，因为你有

notification.defaults |= Notification.DEFAULT_SOUND;
notification.defaults |= Notification.DEFAULT_LIGHTS;

但您需要先将其指定为

notification.defaults = Notification.DEFAULT_SOUND;
notification.defaults |= Notification.DEFAULT_LIGHTS;

或更简单地说@rekaszeru把

notification.defaults = Notification.DEFAULT_SOUND | Notification.DEFAULT_LIGHTS;
