The infamous Casting notification became a very controversial feature for many. It looked like a good idea when it first appeared, but quickly earned much hate as the notifications proved to be spammy in regular use. Google eventually rolled out an option to turn off notifications. If you haven't shunned these notifications, or you're willing to turn them back on, you can look forward to a new twist that makes it possible to tap on the notification to immediately open up an app as a remote control.

This news comes from the developer release notes for Google Play services v15 where it specifies that users will be able to tap on the casting notification to open either the Google Home app, or if the casting session supports joining and the matching app is installed, it will open instead. To put it more clearly, if somebody else is casting with YouTube, the notification will be a shortcut to open the YouTube app on your phone and immediately get access to the current queue, play controls, and any other shared information.

Tapping cast remote control notifications now take users to the Google Home app or the corresponding Cast app, depending on if the Cast app supports joining the session automatically. (source)

This new feature of the notification will come with version 15 of Google Play services, which hasn't been spotted in the wild yet. For now, that notification still offers the basic play controls, but tapping anywhere else on it will do nothing.

Details aren't given in the release notes, but it sounds like any casting app that supports joining will work with this feature out of the box, so developers may not have to ship an update. If joining isn't supported or the app isn't installed, the Google Home app will open instead with its own remote control features. This will probably be the same remote you can already open manually.

Google is making it easier to get the most out of casting and quickly gain access to remote control features. This is especially true for apps that support joining a casting session, a feature that often goes unnoticed. Now if only we could get a physical remote to work with the Chromecast.
