In addition to phones and tablets, Android is available on smart watches, TVs, and even cars. Google he said today Android XR as the next operating system system extended reality (XR). 
Google uses the term extended reality (XR from extended reality) to describe virtual (VR from virtual reality), mixed reality (MR from mixed reality) and augmented reality (AR from augmented reality).
Android XR will be for all types of devices, including those that offer video or optical see-through, “AI glasses” without screen and AR glasses with displays.
Why
Android XR will be more than just creating an operating system for Google itself. It comes to service OEM partners, cultivate a developer ecosystem and manage a new app store.
Google says Android XR is the first operating system built from the ground up with Gemini.
To mention that this is an innovative idea, and this is something we have to admit for Google. Virtual reality as a term has been heard more and more frequently in recent years, so targeting a global operating system, a new ecosystem for developers and a new app store is considered a must.
However, no one started it. Although there have been attempts constructionς headset (from Facebook), and developer kit from Samsung (Project Moohan) nothing has progressed, as far as Google dreams. But apart from the dream, the company also has the resources to realize it.
Of course, sometimes being a pioneer carries risks, especially if you manage to dominate an upcoming market (see monopolies).
