Learn how to initiate chat with an agent in the Brand Messenger Android SDK

Initiate Chat with Agent

For starting the messaging activity, using the following script:;;

If the environment is also configured with Welcome-Messages, the following can be used instead of show(context). This will also send an API request to give the user a welcome-message.


To just send the welcome-message API request without displaying the conversation screen, use the following


Intercept Message Actions

Message actions from SDK conversation screen, such as user tapping on link-buttons, can be intercepted and handled outside of the SDK via a delegate.

BrandMessengerManager.setMessageActionDelegate(new KBMMessageActionDelegate() {
    public boolean onAction(Context context, String action, Message message, Object object, Map<String, Object> replyMetadata) {

Fetch new messages on every chat screen open

The SDK fetches the latest message every time the chat-screen is opened.
This functionality can be enabled/disabled. When disabled, new messages will only be fetches when a push-notification arrives or a mqtt connection message for new message is received.
Default is enabled (true).
