Objective : Send a string from a phone to a wear device.

Why this repo exists: MessageAPI was deprecated recently in Android. Many tutorials were based upon this older API. It was hard to find a simplified working example. This repo focuses on the MessageClient Google have.

How it works: 0) wear.xml is placed in res/values for both wear and mobile. This where the capability is set. A capability can be thought of as advertising "Hey this thing defined right here in the XML I know what it is and I can do it".

Mobile

---

1. This capability is detected programatically. So that we know what capability we need to send to.
2. We then search for the best node. A node in this case is a device, we are interested in the wear device.
3. Once we have the node, we can then use requestTranscription() to perform sending of a message.

Wear

1. Implement the interface ( implements MessageClient.OnMessageReceivedListener )
2. Create a listener ( Wearable.getMessageClient(this).addListener(this); ).
3. Create the onMessageRecieved(MessageEvent event) method. Here we can parse the message recieved that was sent by the Mobile device.

Tested with : Wear : Huawei Watch 2 Phone : Nokia 3
