100M Android activations / 200K apps / 4.5B downloads
Hugo Barra reported 100M Android device activations, 400K daily activations, 200K apps in Android Market and 4.5B total downloads — Android's coming-of-age stats.
All numbers were accurate at the time. Android continued to grow exponentially, passing 1B activations in 2014 and 3B+ active devices in 2021. Android remains the world's largest mobile OS in 2026.
Not a 'shipped product' per se but a milestone announcement.
Android 3.1 Honeycomb
First major update to Android Honeycomb for tablets, featuring resizable home-screen widgets, USB host mode (supporting cameras, keyboards, joysticks, gamepads), and a smoother task switcher. Rolled out to Verizon Motorola Xoom on day of the keynote, with Google TV slated for the summer.
3.1 rolled out to Xoom on schedule May 10, 2011. Honeycomb itself was famously a problematic tablet-only fork — Google never open-sourced it and Android tablets struggled commercially for years. Superseded by Android 4.0 ICS in October.
Shipped exactly as promised but Honeycomb's broader strategy was a market failure.
Android Ice Cream Sandwich (4.0) teaser
Next-generation Android promised for Q4 2011, designed to unify the phone (Gingerbread) and tablet (Honeycomb) codebases into a single OS running on phones, tablets and 'phones-as-laptops'. Featured demo of head-tracking perspective adjustment.
ICS launched October 19, 2011 alongside the Samsung Galaxy Nexus (event postponed one week out of respect for Steve Jobs's death). Galaxy Nexus shipped November 17, 2011 in Europe. Delivered the unified OS promise on schedule.
Roy Want's head-tracking demo never made it to consumer ICS but the unified OS did.
Android Market on the Web (remote install)
Browser-based Android Market at market.android.com letting users buy apps/movies/books on their PC and have them automatically installed on their phone or tablet over the air.
Web Market shipped on schedule in May 2011. Rebranded to Google Play (play.google.com) in March 2012. Remote install from web remains a core Play Store feature in 2026.
Android Open Accessory standard + ADK
New Android Open Accessory protocol letting USB peripherals act as host to Android phones/tablets, with an Arduino-based reference Accessory Development Kit (ADK) given to attendees. Promised available for Android 3.1 and back-ported to 2.3.4.
The AOA protocol shipped in Android 3.1 (May 2011) and was back-ported to Gingerbread 2.3.4 as promised. Adoption stayed niche (hobbyist robotics, exercise equipment) but the API remains in Android.
Quietly successful as a niche API; never reached the mainstream Google hoped for.
Books in Android Market
Books would be merged into a unified Android Market alongside apps, movies and music — a single storefront for all content types, including a redesigned mobile client.
Books integration into Android Market shipped in July 2011 with a redesigned client. The entire Android Market was rebranded to Google Play in March 2012. Google Play Books remains an active Google product in 2026.
Google eBookstore had launched separately in December 2010 and was folded in here.
Chrome GPU acceleration + Speech Input API
Chrome 12 was demoed with full GPU acceleration (showing 10x improvements) and a new HTML5 Speech Input API for voice search/typing on web pages.
GPU acceleration shipped in Chrome 12 (June 2011). The HTML5 Speech Input API shipped as the webkitSpeechRecognition API and remained Chrome-only for years; eventually evolved into the Web Speech API standard, still widely used in 2026.
Chrome reaches 160 million users
Pichai reported Chrome user base doubled YoY from 70M to 160M active users — positioning Chrome as a credible challenger to IE and Firefox.
Chrome continued to explode in popularity, passing Firefox in 2012, IE in 2013, and 1 billion users by 2015. As of 2026 Chrome holds ~65% global browser market share.
More a milestone disclosure than a product.
Chrome six-week release cycle + 160M users
Chrome announced a switch to a rapid six-week release cycle, with Chrome 12 in beta. Chrome user base doubled YoY to 160 million.
Six-week release cycle held steady from 2011 through 2021, when Chrome moved to a four-week cycle. Chrome user base passed 1 billion in 2015 and the browser has dominated market share since 2012.
The release cadence has since been tightened to 4 weeks.
Chrome Web Store internationalization (41 languages)
Chrome Web Store expanded from English-only to 41 languages, opening up the global market to web app developers.
International rollout happened on schedule in summer 2011. Chrome Web Store remains live in 2026, though it's now extension-focused after the Chrome Apps platform was killed (2017 for non-Chrome OS, 2022 for Chrome OS).
Chromebooks (consumer launch with Acer & Samsung)
Sundar Pichai introduced the term 'Chromebook' and announced the first consumer-ready Chrome OS laptops from Samsung (12.1", $429/$499) and Acer (11.6", $349+), shipping June 15, 2011 in seven countries. Pitched as cloud-first computing with 8-second boot and all-day battery.
Both Chromebooks shipped on schedule June 15, 2011. The Chromebook line has grown into a multi-billion-dollar education business and is still an active Google product line in 2026, though Google has signaled a long-term merger of Chrome OS and Android into a unified 'Googlebook' platform.
Rare unambiguous I/O 2011 success. Chromebooks went on to dominate US K-12.
Chromebooks for Business & Education subscription
Monthly subscription model for Chromebooks: $28/user/month for business and $20/user/month for education, bundling hardware, software, support and replacements.
The subscription model launched alongside the Chromebooks on June 15, 2011. The pricing model evolved but Chrome Enterprise/Education Upgrades persist in 2026 as the foundation of Google's biggest Chromebook market.
Education in particular became a massive success.
Google App Engine General Availability + new pricing
Google announced App Engine would graduate from preview/labs to full GA with a new pricing model and a paid-customer SLA later in the year.
App Engine became GA in September 2011 alongside a controversial pricing overhaul that shifted from CPU-hours to instance-hours, raising prices 2x–10x+ for many customers. Sparked significant developer backlash. App Engine remains a live Google Cloud product in 2026.
Shipped on time but the price hike was widely seen as a breach of trust.
Samsung Galaxy Tab 10.1 Limited Edition (attendee giveaway)
Every one of the ~5,000 I/O 2011 attendees received a free 32GB Galaxy Tab 10.1 Limited Edition with stock Honeycomb (no TouchWiz), launching publicly within a month.
Tabs were handed out at the keynote May 10, 2011 and the consumer Galaxy Tab 10.1 launched June 8, 2011 in the US. Samsung sold ~2M units. The Limited Edition I/O tabs got 3.1 OTA within weeks.
Among the most famous I/O attendee gifts ever.
Verizon 4G LTE Mobile Hotspot trial (attendee perk)
I/O 2011 attendees also received a Samsung 4G Mobile Hotspot device with a 3-month free trial of Verizon's 4G LTE service.
Devices and service trials were distributed at the conference as promised. Verizon 4G LTE was at the time the fastest US mobile network and the giveaway helped showcase Honeycomb/tablet cellular use.
Mainly noteworthy as part of the famous 'developer goody bag'.

Google TV update to Honeycomb 3.1 + Android Market
Google TV would receive an update to Android 3.1 Honeycomb with full Android Market access 'this summer', plus open-sourced remote app code.
Honeycomb update missed the summer 2011 window — Google TV 2.0 began rolling out to Sony devices on October 31, 2011, then to Logitech Revue. Logitech famously took a $34M loss writing off unsold Revue inventory and exited the business. Google TV platform was eventually replaced by Android TV in 2014.
Slipped by ~3 months past promised summer timing; platform itself was killed in 2014.
Offline Gmail, Calendar & Docs for Chrome OS
Chrome OS would gain offline support for Gmail, Google Calendar and Google Docs 'over the summer', addressing the #1 criticism of cloud-only Chromebooks.
Offline Gmail launched as a Chrome extension in August 2011. Offline Calendar followed but with read-only and limited editing for a long time. Offline Docs/Drive shipped meaningfully in 2012. All three remain core Chromebook capabilities in 2026.
Gmail shipped on time but Docs/Calendar offline took materially longer than implied.

Android Movie Studio (Honeycomb video editor)
Built-in tablet video editor for Honeycomb with transitions, audio import, splicing, multi-format export and YouTube integration — Google's iMovie answer, demoed across Honeycomb 3.0/3.1 marketing.
Movie Studio shipped pre-installed on Honeycomb tablets but was widely panned as buggy, slow and lacking features. Google never updated it meaningfully and quietly removed it from later Android versions. By 2012, tech press were asking 'whatever happened to Movie Studio?'
Technically launched at MWC 2011 but featured prominently at I/O 2011 Honeycomb materials.
Vapor 3
Android Update Alliance (18-month update commitment)
OEMs (HTC, Samsung, Sony Ericsson, LG, Motorola) and carriers (Verizon, AT&T, T-Mobile, Sprint, Vodafone) committed to providing Android updates for at least 18 months after a device's launch, provided hardware could handle them.
The 'alliance' was never spoken of again. By January 2012 less than 1% of Android devices were on the latest version. No partner ever publicly confirmed adherence and Google never enforced it. Fragmentation remained Android's biggest criticism for years.
One of the most-cited broken Google promises of the decade.
Android@Home framework
An Android-based framework to control home appliances — lights, alarms, thermostats — from any Android device via a low-power 802.15.4 / 6LoWPAN protocol. Lighting Science Group LED bulbs promised by end of 2011.
Android@Home was demoed at I/O 2011 and never went anywhere. No Lighting Science Group bulbs shipped in 2011 or after. The project was abandoned and barely mentioned at I/O 2012. Eventually superseded by entirely different efforts (Brillo 2015, Android Things 2016, both also killed).
The classic I/O 2011 demoware. Lightbulbs never shipped.
Project Tungsten (home media hub)
Glowing-orb / cube prototype Android@Home hub running Android, demoed streaming music from Music Beta to home speakers and using NFC/RFID to add CDs to your library by tapping.
Tungsten was never released as 'Tungsten'. A clear descendant — the Nexus Q — was unveiled at I/O 2012 for $299, then catastrophically pulled before public launch in July 2012 due to bad reviews. Its concepts were repurposed for Chromecast (2013).
Demoware that morphed into the Nexus Q, which itself was killed pre-launch.
Killed 5
Angry Birds for Chrome (WebGL showcase)
Rovio's Mighty Eagle Peter Vesterbacka announced Angry Birds running in Chrome at 60fps using WebGL/Canvas, with Chrome-exclusive 'Chrome Dimension' levels, available free in the Chrome Web Store.
Angry Birds Chrome launched on schedule May 11, 2011. It worked across browsers (not just Chrome). The game was discontinued and removed from the Chrome Web Store on May 4, 2015.
Important demo for the early WebGL ecosystem.
Chrome Web Store in-app payments
In-app payment API for Chrome web apps with a flat 5% fee (vs. Apple/Google Play's 30%). Available immediately in sandbox to US developers, consumer launch and international rollout 'over the summer'.
In-App Payments shipped on the announced timeline. The 5% fee remained a developer favorite for years. Google suspended the system in March 2020 (citing COVID and fraud), deprecated it permanently September 2020, and shut it down February 1, 2021.
Developers were given just months to migrate to alternatives.
Movies in Android Market (rentals)
Movie rentals starting at $1.99 with a 30-day window and 24-hour playback. Streaming and 'pinning' for offline download. Available on Xoom day-of, phones running 2.2+ within 'a couple of weeks', plus web rental at market.android.com.
Movie rentals launched on schedule May 10, 2011. Rebranded to Google Play Movies & TV in 2012. The dedicated Play Movies & TV app was shut down October 5, 2023, with library access migrated to YouTube and Google TV.
Service ran for 12 years before consolidation.
Music Beta by Google (cloud music locker)
Cloud-based music service supporting upload of up to 20,000 songs, smart 'Instant Mix' playlists, offline caching, and cross-device sync. Free during beta, invite-only and US-only at launch.
Music Beta launched as promised May 10, 2011. Publicly launched (still US-only) as 'Google Music' November 16, 2011, then rebranded to 'Google Play Music' in 2012. Replaced by YouTube Music and fully shut down December 2020.
US-only and invite-only at launch generated audible grumbling from the international audience.
RenderScript graphics & compute API
New low-level 3D rendering and parallel compute API for Android (C99-based, JIT-compiled on device), positioned as Google's CUDA-like answer for high-performance Android apps. Heavily featured in I/O 2011 sessions for Honeycomb.
RenderScript shipped in Honeycomb 3.0/3.1 in 2011 and lived in Android for a decade. Google deprecated RenderScript in Android 12 (October 2021) in favor of Vulkan and OpenGL ES, citing limited adoption.
Ran for ~10 years before deprecation.
