【英文标题】：Notification sound isn't changing from default, even after changing in Android

【问题描述】：

我一直在尝试更改通知的声音，但它根本没有改变。 它在所有情况下都使用默认通知，即使我已经分配了频道。 请检查下面的代码，让我知道我哪里出错了。

在应用程序类中创建通知通道

class App : Application() 

    override fun onCreate() 
        super.onCreate()
              createNotificationChannel()
    

    private fun createNotificationChannel() 
        val ordersChannelId = "Orders"
        val orderSoundUri =
            Uri.parse("android.resource://" + applicationContext + "/raw/ordernotification")
        val attributes = AudioAttributes.Builder().setUsage(AudioAttributes.USAGE_ALARM).build()
        val VIBRATE_PATTERN = longArrayOf(0,400,800,600,800,800,800,1000)


        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) 
            val ordersChannel =
                NotificationChannel(ordersChannelId, "Orders", NotificationManager.IMPORTANCE_HIGH)
            ordersChannel.apply 
                description = "This is Orders Channel"
                setSound(orderSoundUri, attributes)
                vibrationPattern = VIBRATE_PATTERN
                importance = NotificationManager.IMPORTANCE_HIGH
            
            val manager = getSystemService(NotificationManager::class.java)
            manager.createNotificationChannel(ordersChannel)
        
    

使用 FireBaseMessagingService 创建通知

class MyFirebaseMessagingService : FirebaseMessagingService() 
  
    override fun onMessageReceived(remoteMessage: RemoteMessage) 
        Log.d("NotificationFire", "From: $remoteMessage?.data")
        val contentIntent = Intent(applicationContext, OrderInDetailActivity::class.java)
        val orderSoundUri = Uri.parse("android.resource://"+applicationContext+"/raw/ordernotification")
        val attributes = AudioAttributes.Builder().setUsage(AudioAttributes.USAGE_ALARM).build()
        val VIBRATE_PATTERN = longArrayOf(0, 500)

        val contentPendingIntent = PendingIntent.getActivity(
            applicationContext,
            0,
            contentIntent,
            PendingIntent.FLAG_UPDATE_CURRENT
        )
           
        remoteMessage?.data?.let 
            Log.d("NotificationFire", "Message Notification Data: $it")

            //Message Services handle notification

           val notification = NotificationCompat.Builder(this, "Orders")
               .setSmallIcon(R.drawable.biskit_logo)
               .setContentTitle(remoteMessage.data.toString())
               .setContentText(remoteMessage.data.toString())
               .setPriority(NotificationCompat.PRIORITY_HIGH)
               .setSound(orderSoundUri)
               .setVibrate(VIBRATE_PATTERN)
               .setCategory(NotificationCompat.CATEGORY_ALARM)
               .setContentIntent(contentPendingIntent)
               .build()
            val notificationManager = NotificationManagerCompat.from(this)
            Log.d("NotificationFire","Notification")
            notificationManager.notify(1,notification)
        

此代码只能以默认声音显示通知。

【问题讨论】：

我记不太清了，但是有 Android 系统设置可以覆盖这个吗？即如果用户将其设置为不允许自定义通知噪音？

"android.resource://" + applicationContext + "/raw/ordernotification" 你的 uri 不应该以 .mp4 或任何你有的格式结尾吗？

【参考方案1】：

在您的声音路径中添加了 applicationContext。它将在您的路径中添加一些随机值。相反，您需要像下面这样添加包名称。

Uri.parse("android.resource://"+context.getPackageName()+"/"+R.raw.FILE_NAME);//Here is FILE_NAME is the name of file that you want to play
