不同的通知声音在Oreo中不工作

问题:
似乎是通知通道问题。

解决方案:
要么创建单独的频道,要么删除自己的频道。

策略:
1)创建单独的通道:
如果你想坚持下去,你可以选择这个策略 多通道 随着 各种各样的 应用程序的配置。
要创建单独的通道,只需在创建时提供唯一的通道ID。
即。:

NotificationChannel channel = new NotificationChannel(uniqueChannelId, name, importance);

2)删除现有频道并重新创建:
如果你想坚持下去,你可以选择这个策略 只有一个频道 随着 更新的 应用程序的配置。

要删除您自己的频道并重新创建它,请执行以下操作:

NotificationManager mNotificationManager = getSystemService(NotificationManager.class);

NotificationChannel existingChannel = notificationManager.getNotificationChannel(channelId);

//it will delete existing channel if it exists
if (existingChannel != null) {
mNotificationManager.deleteNotificationChannel(notificationChannel);
}
//then your code to create channel
NotificationChannel channel = new NotificationChannel(channelId, name, importance);

我从@mehul joisar的回答中得到了解决问题的提示。

正如他写道:

要么创建单独的频道,要么删除 拥有渠道。

我为不同的声音创建了两个独立的频道。

我认为,一旦我们 已创建频道。我们必须移除并创建新的,否则我们 必须为不同的设置创建单独的频道。

在这里,我共享完整的代码来帮助其他人。

private void sendNotification(NotificationBean notificationBean) {
    String textTitle = notificationBean.getTitle();
    String alert = notificationBean.getMessage().getAlert();
    int orderId = notificationBean.getMessage().getOrderId();
    String notificationType = notificationBean.getMessage().getNotificationType();

    Intent intent = new Intent(this, NavigationDrawerActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

    Uri soundUri;
    String channelName;

    if (notificationType.equals("Pending")) {
        channelName = getString(R.string.str_chef);
        soundUri = Uri.parse("android.resource://" + getApplicationContext().getPackageName() + "/" + R.raw.sound);
    }
    else {
        channelName = getString(R.string.str_customer);
        soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    }

    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this, channelName)
            .setSmallIcon(R.drawable.ic_stat_name)
            .setContentTitle(textTitle)
            .setContentText(alert)
            .setSound(soundUri)
            .setContentIntent(pendingIntent)
            .setPriority(NotificationCompat.PRIORITY_DEFAULT);

    // Create the NotificationChannel, but only on API 26+ because
    // the NotificationChannel class is new and not in the support library
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        CharSequence name = getString(R.string.app_name);
        String description = getString(R.string.app_name);
        int importance = NotificationManager.IMPORTANCE_DEFAULT;

        NotificationChannel channel = new NotificationChannel(channelName, name, importance);
        channel.setDescription(description);

        AudioAttributes attributes = new AudioAttributes.Builder()
                .setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
                .setUsage(AudioAttributes.USAGE_NOTIFICATION)
                .build();

        channel.enableLights(true);
        channel.enableVibration(true);
        channel.setSound(soundUri, attributes);

        // Register the channel with the system; you can't change the importance
        // or other notification behaviors after this
        NotificationManager notificationManager = getSystemService(NotificationManager.class);
        notificationManager.createNotificationChannel(channel);
    }

    NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);

    // notificationId is a unique int for each notification that you must define
    notificationManager.notify(101, mBuilder.build());
}

注意:必须先卸载应用程序,然后用此代码进行测试。

谢谢您。
