	ActivationRequest activationReq = ActivationRequest.newBuilder()
			.setVehicleId(vehicleId)
			.setEmailAddress(emailAddress)
			.setFirstName(firstName)
			.setLastName(lastName)
			.setTcIndicator(indicatorEnum)
			.build();
    		
		UconnectMessage msg = UconnectMessage.newBuilder()
			.setTimestamp(System.currentTimeMillis())
			.setMessageId(messageId)
			.addMessages(UconnectAny.newBuilder()
			.setExtension(GlobalUconnectExtActivation.activationRequest, 
			 activationReq))
			.build();

The example code demonstrates how to build Uconnect message and add Activation Request message to it, Similarly you can add other messages

Service Example Code (SDP) for AOTA:

The example code demonstrates how to connect with AWS IoT for publishing and subscribing to the AOTA topic.
