Set Notification Sound As Default Alarm Ringtone

What I've discovered is, that if I set notification sound as devices default alarm ringtone like this: val alarmTone = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM) val

Solution 1:

After 8.0 Oreo You may have created the channel for play notification sound.

private static void initChannels(NotificationManager notificationManager) {
    if (Build.VERSION.SDK_INT < 26) {
        return;
    }

    NotificationChannel channel = new NotificationChannel("ID",
            "NAME",
            NotificationManager.IMPORTANCE_LOW);
    channel.setDescription("DESC");
    channel.enableVibration(false);
    AudioAttributes audioAttributes = new AudioAttributes.Builder()
            .setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
            .setUsage(AudioAttributes.USAGE_NOTIFICATION_RINGTONE)
            .build();
    channel.setSound(Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.notification), audioAttributes);

    notificationManager.createNotificationChannel(channel);
}

Make sure you are using targetSdkVersion 26 or above
