Custom Notification Sound not working in Android Oreo
This might help the new comers.
Here is a code for a working notification sample on all android versions with all kinds of possible setups.
1 -> sound and vibration
2 -> sound but no vibration
3 -> no sound but vibration
4 -> no sound no vibration

To set a sound to notifications in Oreo, you must set sound on NotificationChannel and not on Notification Builder itself. You can do this as follows
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);
}
This will set a custom sound to your notifications. But if the app is being updated and the notification channel is used before, it won't be updated. i.e. you need to create a different channel and set sound to it to make it work. But this will show multiple channels in the notifications section of app info of your app. If you are setting sound to an entirely new channel that is fine, but if you want the channel being used before, you have to delete the existing channel and recreate the channel. To do that you can do something like that before creating channel
if (mNotificationManager != null) {
List<NotificationChannel> channelList = mNotificationManager.getNotificationChannels();
for (int i = 0; channelList != null && i < channelList.size(); i++) {
mNotificationManager.deleteNotificationChannel(channelList.get(i).getId());
}
}
