With more and more manufacturers creating "gaming" mobile and successful online video games such as the Fortnite that comes to Android, makes sense for Google to wish to support developers in any way they can. As it turns out, Google is working on its own Android Game SDK based on Vulkan and Android NDK.
As we all know, the Android is the most popular operating system in the world and it is not surprising that Android has become a popular platform and is expecting new games to grow. This includes three-dimensional games such as PUBG and Fortnite, which are in great demand. However, these games are very complex for them developers. So to give them better control over the complexities of 3D graphics and not have to optimize for each individual Android device, Google is working on a project called it "Android Game SDK". The company had made this announcement public since September, and in particular the SDK includes a Swappy library built on Vulkan graphics API and seems to have been designed to give Android game developers a "fine-grained" control over things, such as the swap interval.
One of Google's goals for the Android Game SDK is to improve the 3D engine performance on Android. In fact, one of the samples is for use only by Unity. This is not the first time that Google has worked with Unity for projects, as we know from the past that Unity founder John Riccitiello appeared on Google I / O 2016 to help show Daydream VR.
So far, it's too early to see what improvements Unity or other machines will see when using the Android Game SDK, and it will take several months for us to hear something official. Nevertheless, Google seems to go one step further with Android Gaming.
