Google has rolled out the official Google Cast SDK for all developers, which could, in essence, open the door to a bunch of new apps with Chromecast support. Those developers wishing to utilize the tools should note that the SDK has “undergone a thorough overhaul since the developer preview release”. In other words, be sure to read through the documents, notes, and other files before starting up.
Just incorporate the SDK into your existing mobile and web apps to bring your content to the TV. You are in control of how and when you develop and publish your cast-ready apps through the Google Cast developer console. The SDK is available on Android and iOS as well as on Chrome through the Google Cast browser extension.
Is there a particular app or game that you would like to see take advantage of the Google Chromecast?
