The Android platform may have started as a smartphone platform, but it has quickly moved into other device form factors. Android tablets have been especially popular. For TV, Google released Google TV. Most recently, the Android Wear SDK, released as a developer preview, will allow Android to work on smaller wearables.
Google has also released its design and development guidelines for these different types of devices, focused on maximizing where the devices are similar and handling the differences as necessary. In this chapter, we talk about some of the best practices to use when developing for different types of devices such as tablets, TVs, and wearables.
