This means that the user

The generation of Android operating systems with the highest operating efficiency in history is coming soon.

2. Daydream: a vr sdk for creating virtual reality experiences on mobile devices. There is an SDK for Unity 3D for creating Android and iOS VR applications, and an SDK for Android.

3. Vulkan: a cross-platform graphic and computing API. It comes from the Khronos Group for modern GPUs. Vulkan is not only applicable to smartphones, but also for PCs, controllers, and even embedded devices. The Vulkan 1.0 specification was released earlier this year.
