When Google announced Android Wear at their Google I/O conference back in March 2014, developers were excited and started embracing this technology to see what types of applications they could create to communicate between the Android handheld device and Android wearable, while making our day-to-day lives a lot easier.

Android wearables bring a personal touch by allowing consumers to interact with their devices on a different level, and are aimed at reducing people's interaction with their mobile phones. This could include receiving a simple notification message reminding you to pick up something on your way home from work, or that you have an upcoming appointment.

In later chapters, we will be working with some of these APIs and seeing how we can incorporate these in our applications to communicate between our Android phone and Android Wear devices.
