自定义通知声音在Oreo中不工作

Uri sound = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE + "://" + context.getPackageName() + "/" + R.raw.notification_mp3);
            mBuilder.setSound(sound);

我已将MP3(notification_mp3.mp3)文件复制到res文件夹的原始文件夹中。当通知被触发时,它会产生给定的MP3声音 安卓本体 但默认声音输入 安卓奥里奥 。我参考了很多网站,但没有任何工作 安卓奥里奥 . 在上面的Android操作系统中,我没有发现Android文档中关于通知声音的任何更改。为了使这个代码在Android O中也能工作,应该做些什么更改?

要在Oreo中将声音设置为通知,必须将声音设置为 NotificationChannel 而不是在 Notification Builder 本身。你可以这样做

Uri sound = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE + "://" + context.getPackageName() + "/" + R.raw.notification_mp3);

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {

        NotificationChannel mChannel = new NotificationChannel("YOUR_CHANNEL_ID",
            "YOUR CHANNEL NAME",
            NotificationManager.IMPORTANCE_DEFAULT)

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

        NotificationChannel mChannel = new NotificationChannel(CHANNEL_ID, 
                context.getString(R.string.app_name),
                NotificationManager.IMPORTANCE_HIGH);

        // Configure the notification channel.
        mChannel.setDescription(msg);
        mChannel.enableLights(true);
        mChannel.enableVibration(true);
        mChannel.setSound(sound, attributes); // This is IMPORTANT


        if (mNotificationManager != null)
            mNotificationManager.createNotificationChannel(mChannel);
    }

这将为您的通知设置自定义声音。但是,如果应用程序正在更新,并且以前使用过通知通道,它将不会被更新。也就是说,你需要创建一个不同的频道,并设置声音使其工作。但这将在应用程序信息的通知部分显示多个频道。如果您将声音设置为全新的频道,这很好,但如果您希望以前使用该频道,则必须删除现有频道并重新创建该频道。要做到这一点,您可以在创建频道之前做类似的事情。

if (mNotificationManager != null) {
            List<NotificationChannel> channelList = mNotificationManager.getNotificationChannels();

            for (int i = 0; channelList != null && i < channelList.size(); i++) {
                mNotificationManager.deleteNotificationChannel(channelList.get(i).getId());
            }
        }

创建一个通道(我在 Application.clss 创建通道)

  public void initChannels(Context context) {
    if (Build.VERSION.SDK_INT < 26) {
        return;
    }
    NotificationManager notificationManager =
            (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
    NotificationChannel channel = new NotificationChannel("default"/*CHANNEL ID*/,
            "CHANNEL_NAME",
            NotificationManager.IMPORTANCE_DEFAULT);
    channel.setDescription("Channel description");
    assert notificationManager != null;
    notificationManager.createNotificationChannel(channel);
}

使用这个频道 default 创建的实例时 NotificationCompat

 .... notificationBuilder = new NotificationCompat.Builder(this,"default") ....

试试这个:

/**
 * show notification
 *
 * @param message
 */
private static void showNotification(RemoteMessage message, Context baseContext) {
    Context context = baseContext.getApplicationContext();
    NotificationManagerCompat managerCompat = NotificationManagerCompat.from(context.getApplicationContext());
    NotificationCompat.Builder builder = new NotificationCompat.Builder(context, null)
            .setSmallIcon(R.drawable.ic_logo_xxxdpi)
            .setContentTitle(message.getData().get(TITLE))
            .setContentText(message.getData().get(BODY))
            .setPriority(NotificationCompat.PRIORITY_HIGH)
            .setAutoCancel(true)
            .setVibrate(new long[]{500, 500})
            .setLights(Color.RED, 3000, 3000)
            .setSound(Settings.System.DEFAULT_NOTIFICATION_URI)
            .setContentIntent(getPendingIntent(context, message));
    managerCompat.notify(getRandom(), builder.build());
}

android o附带了notificationchannel,使用它来代替

 int importance = NotificationManager.IMPORTANCE_HIGH;
            NotificationChannel notificationChannel = new NotificationChannel(NOTIFICATION_CHANNEL_ID, "NOTIFICATION_CHANNEL_NAME", importance);
            notificationChannel.enableLights(true);
            notificationChannel.setLightColor(Color.RED);
            notificationChannel.enableVibration(true);
            notificationChannel.setVibrationPattern(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400});
            assert mNotificationManager != null;
            mBuilder.setChannelId(NOTIFICATION_CHANNEL_ID);
            mNotificationManager.createNotificationChannel(notificationChannel);
