Google Cast was designed to be a really easy experience for both developers and users. This app has some content; that content should be put on a screen. It sounds easy enough, although Google has been working on making more improvements to the SDK so that it’s easier to maintain and quicker. The Cast SDK v3 launches today, deprecating earlier versions. In addition to a library update, there’s example code and documentation for more developers who want to go into more depth.
What’s next for the Cast SDK? There’s a number of upcoming changes that were announced at I/O which are still in the works: a customizable expanded controller and mini controller are two examples. In the meantime, developers seem to be happy with these changes. New widgets were added that comply with best practices on both the mobile and receiver side. Things like dialogs and device discovery are handled by the system so you don’t need to write that yourself.
Initial developer feedback is that first-time implementations can save significant development time compared with our previous SDKs.
The Google Cast site has been updated with this new documentation.
