【中文标题】自定义通知声音在 Android Oreo 中不起作用【英文标题】:Custom Notification Sound not working in Android Oreo 【发布时间】:2018-11-07 02:15:44 【问题描述】: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 文件夹中的 raw 文件夹中。当通知被触发时,它会在 Android Nougat 中产生给定的 mp3 声音,但在 Android Oreo 中产生默认声音。 我推荐了很多网站,但在 Android Oreo 上没有任何效果。我在 Android Docs 中没有发现关于 Android O 及更高版本通知声音的任何变化。 应该进行哪些更改才能使此代码也能在 Android O 中运行?
【问题讨论】:
您在 Android 8.0+ 中设置了通知通道上的声音,而不是通知上的声音。 【参考方案1】:要在 Oreo 中为通知设置声音,您必须在 NotificationChannel
而不是 Notification Builder
本身上设置声音。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。但是如果应用正在更新,并且之前使用了通知渠道,则不会更新。即您需要创建一个不同的频道并为其设置声音以使其正常工作。但这将在您的应用的应用信息的通知部分显示多个频道。如果您将声音设置为一个全新的通道,这很好,但如果您希望之前使用该通道,则必须删除现有通道并重新创建该通道。为此,您可以在创建频道之前执行类似的操作
if (mNotificationManager != null)
List<NotificationChannel> channelList = mNotificationManager.getNotificationChannels();
for (int i = 0; channelList != null && i < channelList.size(); i++)
mNotificationManager.deleteNotificationChannel(channelList.get(i).getId());
【讨论】:
它工作得很好,但只有当应用程序处于前台时。当应用程序处于后台(对于奥利奥)时,我仍然有默认声音。你有解决方案吗? 看看这个答案***.com/a/37845174/2577750 是的,我们需要发送数据消息,谢谢 Ankush,这有帮助 删除后创建通知通道时,系统只使用旧的通道设置。任何人已经能够使用上述方法更改通知通道的声音,如果还有什么需要做的,您可以评论一下。 别忘了你需要重新安装应用程序,否则它会以某种方式回收旧的通知渠道【参考方案2】:这可能会对新来者有所帮助。
这是一个适用于所有 Android 版本以及各种可能设置的工作通知示例的代码。
1 -> sound and vibration
2 -> sound but no vibration
3 -> no sound but vibration
4 -> no sound no vibration

【参考方案3】:创建频道(我在Application.clss
使用这个方法创建频道)
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);
并在创建NotificationCompat
的实例时使用此频道default
.... notificationBuilder = new NotificationCompat.Builder(this,"default") ....
【讨论】:
【参考方案4】:Android O 自带 NotificationChannel 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);
【讨论】:
mNotificationManager
和 mNotificationManager
声明在哪里?
自定义声音在哪里?这没有回答问题。【参考方案5】:
mBuilder.setPriority(NotificationCompat.PRIORITY_HIGH)
这行代码对我有用。但是您必须删除旧频道并创建新频道。
【讨论】:
【参考方案6】:你好,Mates首先使用设备默认的通知声音,添加以下内容。
Uri uri = getDefaultUri(TYPE_NOTIFICATION); // To get the URI of default notification uri
AudioAttributes audioAttributes = new AudioAttributes.Builder().setUsage(AudioAttributes.USAGE_NOTIFICATION_RINGTONE)
.setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION).build();
然后,抱歉,这听起来可能很愚蠢。但您还需要确保设备的默认通知和声音设置为非无。我相信这很容易被忽视。
欢呼!
【讨论】:
【参考方案7】:注释可能有助于模拟器测试。
不要忘记启用如下突出显示的警报声音:-
【讨论】:
【参考方案8】: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());
【讨论】:
这行不通,因为您应该使用通知渠道。以上是关于自定义通知声音在 Android Oreo 中不起作用的主要内容,如果未能解决你的问题,请参考以下文章
