Callback Push Notifications for Android
Genesys Mobile Services (GMS) employs various mechanisms to achieve asynchronous messaging (push notifications). For Android devices, it is a combination of FCM and Comet. Likewise, iOS devices employ APNs and Comet. The scope of this article is limited to how push notifications are handled in Android devices, particularly for the Callback application.
Note: For iOS devices, see CallbackPushNotificationsforiOS.
Procedure
Implementing an FCM client is well documented by Google. Alternately, you can also refer to the Genesys Mobile Services Android Sample for a Genesys FCM implementation.
Push notifications can be divided into two distinct parts:
- Chat (implements push notifications over Comet)
- Callback (implemented over FCM)
For Chat, a Bayeux Client is created to listen to all push notifications related to Chat. The default channel for Chat is /_genesys. The format of Chat push notifications can be seen in the Chat (Comet) section.
For Callback push notifications, refer to the Genesys Mobile Services Android Sample for reference.
Processing of FCM notifications is a three-step procedure:
- Obtain Service ID and Action identifier from FCM Intent.
- Issue HTTP POST to GMS with specified action to obtain action data as JSON.
- Execute action using data provided by GMS.
The data contained within the FCM Intent is structured as follows:
Intent intent;
Bundle extras = intent.getExtras();
String message = extras.getString("message");
System.out.println(message);
---------------------------------------------
Result:
{
"_id":"$(_id)",
"_action":"$(_action)",
}
In the case of the Genesys sample client, the GenesysCloudMessageReceiver repackages the FCM Intent into an application-specific Intent:
Intent newIntent = new Intent(context, GenesysSampleActivity.class);
newIntent.setAction(Globals.ACTION_GENESYS_CLOUD_MESSAGE);
newIntent.putExtra(Globals.EXTRA_MESSAGE, extras.getString("message"));
newIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(newIntent);
This intent is then handled by the GenesysSampleActivity (handleIntent() > interpretCloudMessage()) where the encapsulated data is used to form an HTTP POST with the following URL:
$(ServerURL)$(URLPath)$(_id)/$(_action) for example, http://135.34.145.123:8080/genesys/1/service/3SQI3S31693JL9 L3R0O5O6T4OC000U73/get-dialog-start-chat
| Identifier | Description | Example Values |
|---|---|---|
| $(ServerURL) | URL to Genesys Mobile Services host | http://135.34.145.123:8080 |
| $(URLPath) | Path to Services API | /genesys/1/service/ |
| $(_id) | GMS-issued Service ID | 3SQI3S31693JL9L3R0O5O6T4OC000U73 |
| $(_action) | Callback action to perform | get-dialog-user-confirmation-provide_code-true get-dialog-user-confirmation-provide_code-false |
The response of the HTTP POST request contains JSON, which describes an action to perform and/or UI elements to display in the client application. Each of these requests is referred to as Dialogs.
Dialogs (REST)
The following examples are JSON structures returned by the GMS Callback service to the client application. The contents of the JSON response depend on the Callback action performed (as described in the Procedure section).
Refer to the Genesys Mobile Services Android Sample for examples of how these JSON responses can be interpreted as actions (for example: Call agent, Display menu, Display dialog) and/or UI elements (for example, Confirmation dialogs or Menu items).
