android - 自定义通知声音，安卓奥利奥？

Question

我想在我的应用程序中设置来自原始 mp3 或 wav 文件的自定义通知声音。下面是我的代码

private void sendMyNotification(String message) {
    Intent intent;
    if (sharedPreferences.getBoolean(SPConstants.IS_LOGGED_IN, false)) {
        intent = new Intent(this, ActivityNotification.class);
    } else {
        intent = new Intent(this, ActivitySplash.class);
    }
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT);
    Uri soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    soundUri = Uri.parse("android.resource://" + getApplicationContext().getPackageName() + "/" + R.raw.panic);
    AudioManager manager = (AudioManager)getSystemService(Context.AUDIO_SERVICE);
    manager.setStreamVolume(AudioManager.STREAM_MUSIC, 100, 0);
    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, CHANNEL_ID)
            .setSmallIcon(R.mipmap.ic_launcher)
            .setContentTitle(getString(R.string.app_name))
            .setContentText(message)
            .setAutoCancel(true)
            .setSound(soundUri)
            .setContentIntent(pendingIntent);
    NotificationManager notificationManager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        NotificationChannel mChannel = new NotificationChannel(CHANNEL_ID, channelName, NotificationManager.IMPORTANCE_HIGH);
        notificationManager.createNotificationChannel(mChannel);
    }
    notificationManager.notify(0, notificationBuilder.build());
}

panic 音频文件位于 res->raw 中。我尝试同时使用 mp3 和 wav 格式的声音，但似乎无法设置通知声音。我目前正在 Pixel 2 OS 8.1 上进行测试。

任何建议可能是什么问题？

• 测试了 blow 代码并按预期与我一起工作。

• 添加内容 Intent ，我仍然可以正常工作。

  private void sendMyNotification(String message) {
  
  Intent intent = new Intent(this, SplashActivity.class);
  intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
  PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT);
  
  Uri soundUri = Uri.parse("android.resource://" + getApplicationContext().getPackageName() + "/" + R.raw.correct_answer);
  NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, "CH_ID")
          .setSmallIcon(R.mipmap.ic_launcher)
          .setContentTitle(getString(R.string.app_name))
          .setContentText(message)
          .setAutoCancel(true)
          .setSound(soundUri)
          .setContentIntent(pendingIntent);
  
  NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
  if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
  
      if(soundUri != null){
          // Changing Default mode of notification
          notificationBuilder.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("CH_ID","Testing_Audio",NotificationManager.IMPORTANCE_HIGH);
          notificationChannel.setSound(soundUri,audioAttributes);
          mNotificationManager.createNotificationChannel(notificationChannel);
      }
  }
  mNotificationManager.notify(0, notificationBuilder.build());
  }
