Setup Notification Channel

CE offers a feature to add a custom sound that will be played when a push notification is delivered. Starting from Android 8.0 (API level 26), all notifications must be assigned to a notification channel. For each channel, you can set the visual and auditory behaviour that is applied to all notifications in that channel.

To create a notification channel, implement the following code:

SMTNotificationChannel.Builder smtBuilder = new SMTNotificationChannel.Builder(
                "<Channel_ID>",
                "<Channel_Name>",
                <Notification_Importance>);

//To set the description to the channel add below method. 
smtBuilder.setChannelDescription("<Channel_Description>");

//To set the group ID to the channel add below method. (Make sure that before setting group ID here, that group must be created before. Check the code below)
smtBuilder.setChannelGroupId("<Group_ID>");

//To set sound to channel, add below method. (Note that sound name must be without extention.)
smtBuilder.setNotificationSound("<Sound_File_Name_Without_Extenstion>");

SMTNotificationChannel smtNotificationChannel = smtBuilder.build();

SmartPush.getInstance(new WeakReference<>(context)).createNotificationChannel(smtNotificationChannel);

val smtBuilder: SMTNotificationChannel.Builder= SMTNotificationChannel.Builder(
                "<Channel_ID>",
                "<Channel_Name>",
                <Notification_Importance>)

//To set the description to the channel add below method. 
smtBuilder.setChannelDescription("<Channel_Description>")

//To set the group ID to the channel add below method. (Make sure that before setting group ID here, that group must be created before. Check the code below)
smtBuilder.setChannelGroupId("<Group_ID>")

//To set sound to channel, add below method. (Note that sound name must be without extention.)
smtBuilder.setNotificationSound("<Sound_File_Name_Without_Extenstion>")

val smtNotificationChannel: SMTNotificationChannel = smtBuilder.build()

SmartPush.getInstance(WeakReference(context)).createNotificationChannel(smtNotificationChannel)

Note :
To specify the notification importance, you can pass the below levels.

Importance	User-visible importance level
NotificationManager.IMPORTANCE_HIGH or NotificationManager.IMPORTANCE_MAX	Urgent Makes a sound and appears as a heads-up notification
NotificationManager.IMPORTANCE_DEFAULT	High Makes a sound
NotificationManager.IMPORTANCE_LOW	Medium No sound
NotificationManager.IMPORTANCE_MIN	Low No sound and does not appear in the status bar

For more details, please refer to Google's Channel Importance Level document.

Create a notification channel group

The snippet below demonstrates how to create a notification channel group.

SmartPush.getInstance(new WeakReference<>(context)).createNotificationChannelGroup("<Group_ID>", "<Group_Name>");

SmartPush.getInstance(WeakReference(context)).createNotificationChannelGroup("<Group_ID>", "<Group_Name>")

Delete a notification channel

You can delete notification channels by calling the following method.

SmartPush.getInstance(new WeakReference<>(context)).deleteNotificationChannel("<Channel_ID>");

SmartPush.getInstance(WeakReference(applicationContext)).deleteNotificationChannel("<Channel_ID>")

Delete a notification channel group

You can delete the notification channels group by calling the following method.

SmartPush.getInstance(new WeakReference< (context)).deleteNotificationChannelGroup("<Group_ID>");

SmartPush.getInstance(WeakReference(applicationContext)).deleteNotificationChannelGroup("<Group_ID>")
