android通知通道聲音不起作用

Question

我知道有很多關於這個問題的帖子。 我都試過了。 這是我做的步驟。

首先，我發現頻道一旦創建就無法更改。 唯一的方法是重新安裝應用程序。 所以這就是我所做的，但沒有奏效。

其次，有人說我可以刪除頻道，所以我也使用此代碼這樣做了

val channelList = mNotificationManager.notificationChannels
        var i = 0
        while (channelList != null && i < channelList.size) {
            Log.d("channelList","channel ID is ${channelList[i].id}")
            //mNotificationManager.deleteNotificationChannel(channelList[i].id)
            i++
        }

然后在刪除后重新創建頻道。

第三，我嘗試使用新的通知渠道，但每次使用新渠道時都會出現錯誤。

這是我在嘗試過的所有解決方案中使用的代碼

 val audioAttributes = AudioAttributes.Builder()
                .setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
                .setUsage(AudioAttributes.USAGE_ALARM)
                .build()


        val importance = NotificationManager.IMPORTANCE_DEFAULT

        val channelList = mNotificationManager.notificationChannels
        var i = 0
        while (channelList != null && i < channelList.size) {
            Log.d("channelList","channel ID is ${channelList[i].id}")
            mNotificationManager.deleteNotificationChannel(channelList[i].id)
            i++
        }

        Log.d("isnotification"," is it needed $isNotificationSoundNeeded importance is $importance")
        val mChannel = NotificationChannel(CHANNEL_ID, appName,  NotificationManager.IMPORTANCE_HIGH)
        mChannel.setShowBadge(false)
        mChannel.setSound(notifSound, audioAttributes)



        val mChannelnew = NotificationChannel(CHANNEL_ID2, appName,  NotificationManager.IMPORTANCE_DEFAULT)
        mChannelnew.setShowBadge(false)
        mChannelnew.setSound(notifSound, audioAttributes)




        mNotificationManager.createNotificationChannel(mChannel)

我錯過了什么？ 有任何想法嗎？ 謝謝

更新：這是notifsound的代碼

val notifSound = Uri.parse("android.resource://" + packageName + "/" + R.raw.unconvinced)

首先，我不知道您的通知在Oreo 、 Pie或低於N 的設備上不起作用。

For your question StackOver Flow have lots of answer.

現在根據您的問題您只缺少一行代碼但是由於您尚未粘貼，因此無法檢查您的整個通知代碼。

在這里，我粘貼了一個通知代碼，它只是滿足您的所有通知要求。 （完全自定義通知）

帶有圖像的通知

public void createNotificationWithImage(String title,String message ,Bitmap image) {
PendingIntent resultPendingIntent = PendingIntent.getActivity(mContext,
            0 /* Request code */, resultIntent,
            PendingIntent.FLAG_UPDATE_CURRENT);

// Custom Sound Uri

Uri soundUri = Uri.parse("android.resource://" + mContext.getApplicationContext()
                .getPackageName() + "/" + R.raw.sniper_gun);

 mBuilder = new NotificationCompat.Builder(mContext);
 mBuilder.setSmallIcon(R.mipmap.notification_icon);

 // Pay attention on below line here (NOTE)
 mBuilder.setSound(soundUri);

if (image!=null) {
            mBuilder.setContentTitle(title)
                    .setContentText(message)
                    .setAutoCancel(false)
                    .setLargeIcon(image)
                    .setStyle(new NotificationCompat.BigPictureStyle()
                            .bigPicture(image).setSummaryText(message).bigLargeIcon(null))
                    .setColor(Color.GREEN)
                    .setContentIntent(resultPendingIntent);
        }
mNotificationManager = (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);

現在我正在粘貼可以在上面或在OREO設備上工作的通知代碼。

if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
        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});

        if(soundUri != null){
            AudioAttributes audioAttributes = new AudioAttributes.Builder()
                    .setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
                    .setUsage(AudioAttributes.USAGE_ALARM)
                    .build();
            notificationChannel.setSound(soundUri,audioAttributes);
        }

        assert mNotificationManager != null;
        mBuilder.setChannelId(NOTIFICATION_CHANNEL_ID);
        mNotificationManager.createNotificationChannel(notificationChannel);
    }
    assert mNotificationManager != null;
    mNotificationManager.notify(0 /* Request Code */, mBuilder.build());


below middle braces use for close your method.
}

無圖像通知

    public void createNotification(String title,String message){
    PendingIntent resultPendingIntent = PendingIntent.getActivity(mContext,
                0 /* Request code */, resultIntent,
                PendingIntent.FLAG_UPDATE_CURRENT);

        Uri soundUri = Uri.parse("android.resource://" + mContext.getApplicationContext()
                .getPackageName() + "/" + R.raw.sniper_gun);



        mBuilder = new NotificationCompat.Builder(mContext);
        mBuilder.setSmallIcon(R.mipmap.notification_icon);
        mBuilder.setLargeIcon(BitmapFactory.decodeResource(mContext.getResources(),
                R.mipmap.icon));
        mBuilder.setSound(soundUri);
        mBuilder.setContentTitle(title)
                .setContentText(message)
                .setAutoCancel(false)
                .setColor(Color.GREEN)
                .setStyle(new NotificationCompat.BigTextStyle())
                .setContentIntent(resultPendingIntent);

        mNotificationManager = (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);

        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
            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});
//            notificationChannel.s

            if(soundUri != null){
                AudioAttributes audioAttributes = new AudioAttributes.Builder()
                        .setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
                        .setUsage(AudioAttributes.USAGE_ALARM)
                        .build();
                notificationChannel.setSound(soundUri,audioAttributes);
            }

            assert mNotificationManager != null;
            mBuilder.setChannelId(NOTIFICATION_CHANNEL_ID);
            mNotificationManager.createNotificationChannel(notificationChannel);

        }

        assert mNotificationManager != null;
        mNotificationManager.notify(0 /* Request Code */, mBuilder.build());

    }

注意：在我的代碼中，我提到要注意我描述要使用通知設置聲音 Uri 的特定行。 你可以這樣描述。

mBuilder.setContentTitle(title)
            .setContentText(message)
            .setAutoCancel(false)
            .setSound(soundUri)
            .setColor(Color.GREEN)
            .setStyle(new NotificationCompat.BigTextStyle())
            .setContentIntent(resultPendingIntent);

但它不會為您播放聲音，因為在 Oreo 設備未將聲音設置為優先級之后。

所以總是像我描述的那樣使用聲音代碼。

Answer 2

我猜您使用了錯誤的使用類型，請將您的audioAttributes使用編輯為USAGE_NOTIFICATION

            val audioAttributes = AudioAttributes.Builder()
            .setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
            .setUsage(AudioAttributes.USAGE_NOTIFICATION)
            .build()

來自官方文檔：

USAGE_NOTIFICATION ：當使用是通知時使用的使用值。

Answer 3

您需要使用音頻屬性，還需要在許可的情況下定義鈴聲 URI。

所以首先我們定義鈴聲 URI：

Uri ringtoneUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
boolean vibrate = true;
long[] vibratePattern = new long[]{0L, 1000L};



public constructor(){
 notificationBuilder = new NotificationCompat.Builder(mContext, app.getAppContext().getString(R.string.default_notification_channel_id));
        mNotifyManager = (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);
        mContext.grantUriPermission("com.android.systemui", ringtoneUri, Intent.FLAG_GRANT_READ_URI_PERMISSION);
}
 public void showNotificationNormal(String notificationTitle, String notificationBody, Intent intent) {
    String id = mContext.getString(R.string.default_notification_channel_id);
    PendingIntent lowIntent = PendingIntent.getActivity(mContext, 100, intent, PendingIntent.FLAG_CANCEL_CURRENT);
    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(mContext, id);
    NotificationManager mNotifyManager = (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        CharSequence name = mContext.getString(R.string.default_notification_channel_name);
        String description = mContext.getString(R.string.default_notification_channel_description); //user visible
        int importance = NotificationManager.IMPORTANCE_HIGH;

        AudioAttributes att = new AudioAttributes.Builder()
                .setUsage(AudioAttributes.USAGE_NOTIFICATION)
                .setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
                .build();

        NotificationChannel mChannel = new NotificationChannel(id, name, importance);
        mChannel.setDescription(description);
        mChannel.enableLights(true);
        mChannel.enableVibration(vibrate);
        mChannel.setVibrationPattern(vibratePattern);
        mChannel.setLightColor(Color.RED);
        mChannel.setSound(ringtoneUri, att);
        mChannel.setBypassDnd(true);
        mChannel.setLockscreenVisibility(NotificationCompat.VISIBILITY_PUBLIC);
        mChannel.setShowBadge(true);

        if (mNotifyManager != null) {
            mNotifyManager.createNotificationChannel(mChannel);
        }

        notificationBuilder
                .setSmallIcon(R.mipmap.ic_launcher)
                .setPriority(NotificationCompat.PRIORITY_MAX)
                .setCategory(NotificationCompat.CATEGORY_MESSAGE)
                .setVibrate(vibratePattern)
                .setSound(ringtoneUri)
                .setColor(ContextCompat.getColor(mContext, R.color.colorPrimary))
                .setContentTitle(notificationTitle)
                .setStyle(new NotificationCompat.BigTextStyle().bigText(notificationBody))
                .setAutoCancel(true)
                .setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
                .setContentIntent(lowIntent);

    } else {
        notificationBuilder.setContentTitle(notificationTitle)
                .setSmallIcon(R.mipmap.ic_launcher)
                .setPriority(NotificationCompat.PRIORITY_MAX)
                .setCategory(NotificationCompat.CATEGORY_MESSAGE)
                .setVibrate(vibratePattern)
                .setSound(ringtoneUri)
                .setStyle(new NotificationCompat.BigTextStyle().bigText(notificationBody))
                .setColor(ContextCompat.getColor(mContext, R.color.colorPrimary))
                .setAutoCancel(true)
                .setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
                .setContentIntent(lowIntent);

    }

    notificationBuilder.setContentText(notificationBody);

    if (mNotifyManager != null) {
        mNotifyManager.notify(AppConstants.NOTIFY_ID, notificationBuilder.build());
    }
}
