From smartphones to watches to TVs, Google will soon reveal what it has planned as Google I/O kicks off today, Tuesday, May 18, with more than two hours of keynotes. The pre-show for the keynote has already begun.

The Google I/O keynote is a must-see event if you are interested in what's next for Android phones. It will also likely include the latest news on Chrome, Google's smart home products, wearables news, and especially search. Of course, you can cover the keynotes on Tom's Guide's Google I/O live blog, or watch the I/O live stream yourself.

We've compiled a list of all the ways you can watch the Google I/O keynotes this week.

Google is currently streaming the keynote on its Google I/O website. You can also watch the live stream on Google's YouTube channel.

Google I/O runs from Tuesday, May 18 through Thursday, May 20, and is the Google Developer Conference with sessions throughout the three days. Last year's get-together was canceled early in the coronavirus pandemic. This time around, Google is using an all-virtual conference rather than gathering attendees at its headquarters in Mountain View, California.

The good news about the all-virtual Google I/O is that it is easy for everyone to attend. And even if you're not an Android developer, you'll want to pay attention to the opening keynote, which begins today at 1:00 pm ET / 10:00 am ET.

Other notable sessions include a developer keynote at 3:15 p.m. ET/12:15 p.m. PT today, which promises to dive deeper into Google's announcements; the What's New in Android session is at 4:00 30 p.m. ET/1:30 p.m. PT to follow.

Our preview of Google I/O 2021 takes a closer look at the announcements we may hear during Tuesday's keynote. However, since Google always showcases the changes it makes to its mobile software at its developer conferences, we can be sure that there will be a detailed preview of Android 12 at this event. Interface changes, new widgets, one-handed mode, and the ability to launch pairs of apps simultaneously are likely enhancements.

Google I/O usually features more than updates to Android for cell phones. We'll likely hear about in-car Android, changes to TVs, and new features coming to the Google Assistant. Speaking of software smarts, Google likes to use I/O to showcase new features in Google Lens, Google Duplex, and other services that benefit from its advantages in search and machine learning.

As for hardware, rumors of a mid-range smartphone called the Pixel 5a have been floating around, but opinions are divided on whether it will appear at Google I/O or whether Google will wait until after the summer to announce the phone. It seems more likely that the new Pixel Buds A series earbuds will appear at Google I/O, and Google may say something about smartwatches and smart speakers when discussing Wear OS and smart home platform enhancements.
