In this chapter, we learned new ways of working with fitness sensors using the Google Fit platform. The Google Fit platform simplifies the whole process of sensor data collection, storage, and retrieval by taking on most of the responsibility itself. The application has to do the minimal work of requesting and querying the fitness data. The Google Fit platform has been developed to deal only with fitness sensor data. It doesn't deal with other sensor data. The Google Fit platform also does a great job of maintaining and syncing all your fitness data on multiple devices, so if you use Android Wear and an Android phone, then both of them track your step counts differently, but at the end of the day you will find that the step count data is the same on both of them.
In the next bonus chapter, we will explore sensors-based APIs and their use in real-world applications. We will also discuss new examples of combining two or more sensors' data together, which is commonly referred to as sensor...
