public interface WearableMessageListener

Notified when the peer app sends a live message.

Callbacks arrive on the EDT. A message that arrived while your app was starting – including the one that caused the platform to launch it – is replayed to the first listener you register, so register from your app’s init() rather than from a form.

Methods

public abstract WearableMessage messageReceived(WearableMessage message, boolean expectsReply) Called when a message arrives from the peer app.

Method details

messageReceived

public abstract WearableMessage messageReceived(WearableMessage message, boolean expectsReply)

Called when a message arrives from the peer app.

If the sender asked for a reply, answer it by returning a message; returning null sends an empty reply. The sender is blocked waiting, so answer quickly and do slow work afterwards.

Parameters

message WearableMessage: the received payload, addressed to the path the sender chose
expectsReply boolean: true when the sender is waiting for an answer

Returns

the reply to send back, or null for none
