Android Oreo无法播放自定义声音以进行通知

问题描述

我正在尝试向API> 26的通知添加自定义声音。以下是代码

I am trying to add a custom sound to notification for API > 26. Below is the code

NotificationChannel notificationChannel = new NotificationChannel("channel id","channel name",NotificationManager.IMPORTANCE_HIGH);
mNotificationManager.createNotificationChannel(notificationChannel);
AudioAttributes audioAttributes = new AudioAttributes.Builder()
                    .setContentType(AudioAttributes.CONTENT_TYPE_MUSIC)
                    .setUsage(AudioAttributes.USAGE_NOTIFICATION)
                    .build();
notificationChannel.setSound(Uri.parse("android.resource://" + BuildConfig.APPLICATION_ID + "/raw/beep"),audioAttributes);

这里的问题是它播放设备的默认钢琴声音，而不是播放资产的哔声。我不允许使用铃声管理器，但常识性统计表明通知声音应该是指定的声音而不是默认声音。

The problem here is that it, plays default piano sound of device rather than playing beep sound from assets. I am not allowed to use ringtone manager but common sense stats that notification sound should be that which is specified rather than default.

对于API< = 26来说很好用

It works fine for API <= 26

推荐答案

最后我设法自己找到了解决方案。下面是代码

Finally I managed to find a solution on my own. Below is the code

NotificationManager mNotificationManager =
                (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
 if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {

            if(notificationSoundUri != null){
                // Changing Default mode of notification
                notificationCompatBuilder.setDefaults(Notification.DEFAULT_VIBRATE);

                // Creating an Audio Attribute
                AudioAttributes audioAttributes = new AudioAttributes.Builder()
                        .setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
                        .setUsage(AudioAttributes.USAGE_ALARM)
                        .build();

                // Creating Channel
                NotificationChannel notificationChannel = new NotificationChannel(context.getString(R.string.channel_id_prayers),context.getString(R.string.channel_name_prayers),NotificationManager.IMPORTANCE_HIGH);
                notificationChannel.setSound(notificationSoundUri,audioAttributes);
                mNotificationManager.createNotificationChannel(notificationChannel);
            }
}
mNotificationManager.notify(0, notificationCompatBuilder.build());
