【问题描述】：

在 android 10 之前，我一直使用自定义声音推送通知。从 Android 11 开始，当通知以下拉样式呈现时，附加到通知通道的声音停止播放。当它显示为全屏活动时，它可以工作。

这里是如何创建通知通道的示例源代码

private void createNotificationChannel() 
    // 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) 

    String channelId = "media_playback_channel_v_01_1_sound"
    String channelName = "Channel High"
        NotificationChannel channel = new NotificationChannel(channelId, channelName, NotificationManager.IMPORTANCE_HIGH);
        channel.setDescription("My custom sound");
        channel.setLockscreenVisibility(Notification.VISIBILITY_PUBLIC);

        AudioAttributes.Builder builder = new AudioAttributes.Builder();
        builder.setUsage(AudioAttributes.USAGE_NOTIFICATION);
    String basePath = ContentResolver.SCHEME_ANDROID_RESOURCE + "://" + getPackageName() + "/" + R.raw.alarm_sound);
    Uri alarmSound = Uri.parse(basePath);
        channel.setSound(alarmSound, builder.build());

        channel.enableVibration(true);
        channel.enableLights(true);
        channel.setLightColor(Color.RED);
    

我使用上面的通知通道并按如下方式触发通知：

private void fireNotification(Context context) 
    String channelId = "media_playback_channel_v_01_1_sound"
        NotificationChannel channel = getManager().getNotificationChannel(channelId);


        PendingIntent fullScreenPendingIntent = PendingIntent.getActivity(context, 100,
                fullScreenIntent, PendingIntent.FLAG_UPDATE_CURRENT);
        String contentText = getString(R.string.call_notification_incoming_from, from);

        Bundle args = new Bundle();
        args.putInt(CallActivity.INTENT_CALL_NOTIFICATION_ID, ActiveCall.ANDROID_10_PUSH_CALL_NTFN_ID);
        args.putBoolean(CallActivity.INTENT_FROM_CALL_NOTIFICATION, true);
        args.putString(CallActivity.INTENT_NOTIFICATION_CALL_ID, fullScreenIntent.getStringExtra(CallActivity.INTENT_NOTIFICATION_CALL_ID));

        NotificationCompat.Builder notificationBuilder =
                new NotificationCompat.Builder(this, type)
                        .setSmallIcon(iconRes)
                        .setContentTitle(getString(R.string.app_name))
                        .setContentText(contentText)
                        .setPriority(NotificationCompat.PRIORITY_HIGH)
                        .setCategory(NotificationCompat.CATEGORY_CALL)
                        .setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
                        .setOngoing(true)
                        .setGroupAlertBehavior(NotificationCompat.GROUP_ALERT_ALL)
                        .setTimeoutAfter(Consts.MINUTE)
                        .addExtras(args);

    notificationBuilder.addAction(
        R.drawable.ic_accept_call,
                getString(R.string.call_notification_incoming_answer),
                answerPendingIntent);
        notificationBuilder.addAction(
                        R.drawable.ic_decline_bttn,
                        getString(R.string.call_notification_incoming_reject),
                        rejectPendingIntent
                );
        notificationBuilder.setFullScreenIntent(fullScreenPendingIntent, true);

    // Build
        Notification notification = notificationBuilder.build();
    notification.sound = notificationSoundUri;
        notification.flags |= (Notification.FLAG_SHOW_LIGHTS | Notification.FLAG_INSISTENT Notification.FLAG_NO_CLEAR);
        notification.ledARGB = Color.RED;
        notification.ledOnMS = 300;
        notification.ledOffMS = 1000;

    // Notify
        NotificationManager notificationManager = getManager();
        notificationManager.notify(id, notification);

请注意，相同的代码会在 Android 10 中播放声音，而在 Android 11 中则不会。

【问题讨论】：

您找到解决方案了吗？我在一些三星和索尼 android 11 设备上看到了这个问题。但不适用于一加和 Pixel。

这方面有什么更新吗？面临完全相同的问题...

我还没有找到解决办法。

【参考方案1】：

我也被困在 android 11 上，但我尝试了 不同的 频道名称并且没有频道 ID。

此解决方案适用于所有 android 版本 11 设备。

请试试这个，如果这对你不起作用，请告诉我。

public void showNotification(String title, String message) 
        count++;
        Intent intent = new Intent(this, HomePageActivity.class);
        String channel_id = "notification_channel";
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT);
        Uri soundUri = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE + "://" + getApplicationContext().getPackageName() + "/" + R.raw.coin);
        NotificationCompat.Builder builder = new NotificationCompat.Builder(getApplicationContext(), channel_id)
                .setSmallIcon(R.mipmap.ic_launcher_round)
                .setAutoCancel(true)
                .setVibrate(new long[]1000, 1000, 1000, 1000, 1000)
                .setOnlyAlertOnce(true)
                .setSound(soundUri)
                .setContentIntent(pendingIntent);
        builder.setNumber(count);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) 
            builder = builder.setContent(getCustomDesign(title, message));
         else 
            builder = builder.setContentTitle(title).setContentText(message).setSmallIcon(R.mipmap.ic_launcher_round);
        
        NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) 
            NotificationChannel notificationChannel = new NotificationChannel(channel_id, "DIFFRENT_CHANNEL_NAME", NotificationManager.IMPORTANCE_HIGH); // Here I tried put different channel name.
            notificationChannel.setShowBadge(true);
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) 
                notificationChannel.canBubble();
            
            AudioAttributes audioAttributes = new AudioAttributes.Builder()
                    .setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
                    .setUsage(AudioAttributes.USAGE_NOTIFICATION)
                    .build();

            notificationChannel.canShowBadge();
            notificationChannel.enableVibration(true);
            notificationChannel.setSound(soundUri, audioAttributes);
            notificationManager.createNotificationChannel(notificationChannel);
            notificationManager.notify(0, builder.build());
        
    

【讨论】：

我想了解你在这里做了什么。是不是只改成"DIFFRENT_CHANNEL_NAME"？

是的，我使用了不同的频道名称，但我不知道这对 android 11 是如何工作的
