In this chapter, we have studied the sensors, battery utilizations, and the best practices. We have additionally looked at how the doze mode helps to spare the battery and spare the CPU cycles. You have learned how to construct a material design Wear application using ideas such as making fragments for Wear devices, working with WearableNavigationLayout, working with WearableActionDrawer, working with services and BroadcastReceivers, and working with sensors, such as the optical HeartRate sensor and step counter, the notifications for the step counter and drink water services, and runtime permissions for the body sensors.
In the next chapter, we anticipate making this application more solid by using more elements and functionalities.
