首先,此问题出现在所有Android 8.0设备上,但很容易修复,我的通知通道优先级设置为IMPORTANCE_LOW.但问题仍然存在于三星设备上.

所以,问题是,如何在Samsung 8.0设备上静默更新前台服务通知？

我的代码如下.

申请类：

override fun onCreate() {
        super.onCreate()
        //other code
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            notificationManager.createNotificationChannels(listOf(
                    //
                    NotificationChannel(MY_NOTIFICATION_CHANNEL,"My channel",NotificationManager.IMPORTANCE_LOW).apply {
                        setSound(null,null)
                    }
                    //
            ))
        }
    }

服务开始前景：

val notification = NotificationCompat.Builder(this,MY_NOTIFICATION_CHANNEL)
                .setSmallIcon(android.R.drawable.stat_sys_warning)
                .setColor(App.context().resources.getColor(R.color.primary_dark))
                .setContentText(if (/*logic*/) "This" else "That")
                .addAction(0,if (enable) "Disable" else "Enable",firstIntent)
                .addAction(0,"Another action",secondIntent)
                .build()

        startForeground(MY_NOTIFICATION_ID,notification)
