Android 通知既没有声音也没有振动

我在向fcm发布数据后发出通知，当我收到返回的数据时，通知显示没有问题，但没有声音没有振动即使我确保我的手机启用了声音和振动，我不确定我是否做错了什么，请帮我解决，谢谢

• 这是我的应用程序类代码，我在其中为oreo设置了通知通道+

• 这是我的通知代码

我的问题的解决方案是简单地设置默认声音，如下所示

---

setDefaults（NotificationCompat.DEFAULT\u SOUND）

检查应用程序是否允许显示通知并可以执行振动。转到Emulator/Physical Device中的设置和应用设置我已经检查过了，并且我的应用程序和myphone中的大多数应用程序都启用了这两个设置，我不确定这是否与优先级或其他因素有关
