If correct the feature would potentially allow photos, videos and other media content stored in the cloud on Google Drive to be streamed to a nearby TV or display straight from the Android app.
Yes, you read that right: native cast support for playing audio and video from files stored in your Google Drive storage to your TV. No need for third-party solutions like RealPlayer’s (excellent) CloudPlayer tool.
The code referencing Google Drive Chromecast support was spotted by Android Police in an “APK teardown” of the cloud backup app’s latest Play Store release who also noted support for ‘setting up the cast and adding metadata’ – e.g., artist, track number, album name for audio and series episode number for videos.
While the presence of this code is not strict confirmation that such a feature is coming it would be a logical move for Google. I imagine many users are surprised that Google Drive Chromecast features aren’t already built-in.
