Google announced a slew of updates at its I/O developer conference today, covering software for all sorts of devices like phones, wearables, foldables and more. One of these platforms is Android TV, and in addition to a bunch of developer-centric improvements, the company is also introducing new Cast Connect, Stream Transfer and Stream Expansion tools. These should make it easier to play things on Cast devices, once developers build the functionality into their apps.
Cast Connect will let you send content from your phone, tablet or Chrome browser onto an app on Android TV. Right now if you cast to an Android TV device, it's not targeted to specific apps on the bigger screen. This might also allow for some control around what you're casting and possibly some interaction with the TV app.
