API 26 上未显示 Android 通知

Question

我最近将我的应用更新到 API 26，通知不再起作用，甚至没有更改代码。

val notification = NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.ic_notification)
                .setContentTitle("Title")
                .setContentText("Text")
                .build()
(getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager).notify(1, notification)

为什么它不起作用？ API 是否有一些我不知道的变化？

Answer 1

来自 the documentation :

Android O introduces notification channels to provide a unified system to help users manage notifications. When you target Android O, you must implement one or more notification channels to display notifications to your users. If you don't target Android O, your apps behave the same as they do on Android 7.0 when running on Android O devices.

_(强调)

您似乎没有将此 Notification 与 channel 相关联。
