Android Auto

Android Auto is a mobile app developed by Google to mirror features from an Android device (e.g., smartphone) to a car's compatible in-dash information and entertainment head unit or to a dashcam.

Once an Android device is paired with the head unit, the system mirrors qualified apps from the device to the vehicle's display, with a simple, driver-friendly user interface. Supported apps include GPS mapping/navigation, music playback, SMS, telephone, and web search. The system supports both touchscreen and button-controlled head unit displays, although hands-free operation through voice commands is encouraged to minimize driving distraction.

Android Auto debuted at Google I/O 2014, and the app was released on 19 March 2015. Android Auto is part of the Open Automotive Alliance announced on 25 June 2014, and is a joint effort between 28 automobile manufacturers, with Nvidia as tech supplier. It is available in 28 countries.

Android Froyo

Android "Froyo" is the sixth update of Android and is a codename of the Android mobile operating system developed by Google, spanning versions between 2.2 and 2.2.3. Those versions are no longer supported. It was unveiled on May 20, 2010, during the Google I/O 2010 conference.

One of the most prominent changes in the Froyo release was USB tethering and Wi-Fi hotspot functionality. Other changes include support for the Android Cloud to Device Messaging (C2DM) service, enabling push notifications, Additional application speed improvements, implemented through JIT compilation and displayed within applications as top-of-the-screen banners.

Android Lollipop

Android "Lollipop" is a codename for the Android mobile operating system developed by Google, spanning versions between 5.0 and 5.1.1. Unveiled on June 25, 2014 at the Google I/O 2014 conference, it became available through official over-the-air (OTA) updates on November 12, 2014, for select devices that run distributions of Android serviced by Google (such as Nexus and Google Play edition devices). Its source code was made available on November 3, 2014. It is the fifth major update and the twelfth version of Android.

One of the most prominent changes in the Lollipop release is a redesigned user interface built around a design language known as Material Design, which was made to retain a paper-like feel to the interface. Other changes include improvements to the notifications, which can be accessed from the lockscreen and displayed within applications as top-of-the-screen banners. Google also made internal changes to the platform, with the Android Runtime (ART) officially replacing Dalvik for improved application performance, and with changes intended to improve and optimize battery usage.

As of October 2018, statistics issued by Google indicate that the Lollipop versions have 17.9% share combined of all Android devices accessing Google Play.Lollipop is succeeded by Marshmallow, which was released in October 2015.

Android Studio

Android Studio is the official integrated development environment (IDE) for Google's Android operating system, built on JetBrains' IntelliJ IDEA software and designed specifically for Android development. It is available for download on Windows, macOS and Linux based operating systems. It is a replacement for the Eclipse Android Development Tools (ADT) as the primary IDE for native Android application development.

Android Studio was announced on May 16, 2013 at the Google I/O conference. It was in early access preview stage starting from version 0.1 in May 2013, then entered beta stage starting from version 0.8 which was released in June 2014. The first stable build was released in December 2014, starting from version 1.0. The current stable version is 3.3, which was released in January 2019.

Android Things

Android Things (codenamed Brillo) is an Android-based embedded operating system platform by Google, announced at Google I/O 2015. It is aimed to be used with low-power and memory constrained Internet of Things (IoT) devices, which are usually built from different MCU platforms. As an IoT OS it is designed to work as low as 32–64 MB of RAM. It will support Bluetooth Low Energy and Wi-Fi. Along with Brillo, Google also introduced the Weave protocol, which these devices can use to communicate with other compatible devices.Google provides OEM implementations of Android Things designed for the production of Google Assistant-powered smart speakers and displays running one of two Qualcomm "Home Hub" systems-on-chip. Products have been developed by JBL, Lenovo, and LG Electronics.

Google ATAP

Google's Advanced Technology and Projects group (ATAP) is a skunkworks team and in-house technology incubator, created by former DARPA director Regina Dugan. ATAP is similar to X, but works on projects, granting project leaders time--previously only two years--in which to move a project from concept to proven product. According to Dugan, the ideal ATAP project combines technology and science, requires a certain amount of novel research, and creates a marketable product. Historically, the ATAP team was born at Motorola and kept when Google sold Motorola to Lenovo; for this reason, ATAP ideas have tended to involve mobile hardware technology.

The team embodies principles that former Google VP Dugan used at DARPA,. One of these principles is to create small teams of high performers. Another is to make use of resources outside the organizational box; ATAP has worked with hundreds of partners in more than twenty countries, including schools, corporations, startups, governments, and nonprofits. Standing contracts are in place with a number of top-flight schools, such as Stanford, MIT, and Caltech, to facilitate rapid research arrangements when needed.

Google Cardboard

Google Cardboard is a virtual reality (VR) platform developed by Google for use with a head mount for a smartphone. Named for its fold-out cardboard viewer, the platform is intended as a low-cost system to encourage interest and development in VR applications. Users can either build their own viewer from simple, low-cost components using specifications published by Google, or purchase a pre-manufactured one. To use the platform, users run Cardboard-compatible applications on their phone, place the phone into the back of the viewer, and view content through the lenses.

The platform was created by David Coz and Damien Henry, French Google engineers at the Google Cultural Institute in Paris, in their 20% "Innovation Time Off". It was introduced at the Google I/O 2014 developers conference, where a Cardboard viewer was given away to all attendees. The Cardboard software development kit (SDK) is available for the Android and iOS operating systems; the SDK's VR View allows developers to embed VR content on the web as well as in their mobile apps.Through March 2017, over 10 million Cardboard viewers had shipped and over 160 million Cardboard app downloads had been made. Following the success of the Cardboard platform, Google announced an enhanced VR platform, Daydream, at Google I/O 2016.

Google Daydream

Daydream is a virtual reality (VR) platform developed by Google that is built into the Android mobile operating system (versions "Nougat" 7.1 and later). Compatible phones that follow the platform's software and hardware specifications (and are thus designated "Daydream-ready") are used in the Google Daydream View VR headset. The Daydream platform was announced at the Google I/O developer conference in May 2016, with the first VR headset released on November 10, 2016. Daydream is the company's second VR platform following Google Cardboard, which was a low-cost system intended to encourage interest in VR and was built into compatible mobile apps rather than the operating system itself.

It is not to be confused with the "Daydream" screensaver feature that had been introduced with Android 4.2 in 2012 and was renamed to "screen saver" after the 2016 launch of the VR platform.

Google Goggles

Google Goggles was an image recognition mobile app developed by Google. It was used for searches based on pictures taken by handheld devices. For example, taking a picture of a famous landmark searches for information about it, or taking a picture of a product's barcode would search for information on the product.

Google Lens

Google Lens is an image recognition mobile app developed by Google. First announced during Google I/O 2017, it is designed to bring up relevant information using visual analysis.

Google Now

Google Now was a feature of Google Search of the Google app for Android and iOS. Google Now proactively delivered information to users to predict (based on search habits and other factors) information they may need in the form of informational cards. Google Now branding is no longer used, but the functionality continues in the Google app and its feed.Google first included Google Now in Android 4.1 ("Jelly Bean"), which launched on July 9, 2012, and the Galaxy Nexus smartphone was first to support it. The service became available for iOS on April 29, 2013, without most of its features. In 2014, Google added Now cards to the notification center in Chrome OS and in the Chrome browser. Later, however they removed the notification center entirely from Chrome. Popular Science named Google Now the "Innovation of the Year" for 2012.Since 2015, Google gradually phased out reference to "Google Now" in the Google app, largely removing remaining use of "Now" in October 2016, including replacing Now cards with Feed. At Google I/O 2016, Google showcased its new intelligent personal assistant Google Assistant, in some ways an evolution of Google Now. Unlike Google Now, however, Assistant can engage in two-way dialogue with the user.

Google Play Games

Google Play Games is an online gaming service and software development kit operated by Google for the Android operating system. It features gamer profiles, cloud saves, social and public leaderboards, achievements, and real-time multiplayer gaming capabilities.The Play Games service allows developers to incorporate the above features into their games without having to develop those features from scratch themselves.

The Google Play Games service was introduced at the Google I/O 2013 Developer Conference, and the standalone Google Play Games mobile app was launched for Android on July 24, 2013.Andrew Webster of The Verge compared Google Play Games to Game Center, a similar gaming network for users of Apple Inc.'s own iOS operating system.Google Play Games has received updates over the years since its launch, including a screen-recording feature, custom gamer IDs, built-in games, and an arcade for game discovery.

List of Google apps for Android

e Google Play Store, although some may not show up in search results if they are listed as incompatible with your device (even though they may still function from an *.apk). Some of Google's apps may be pre-installed on some devices, depending upon the device manufacturer and the version of Android. A few of these apps, such as Gboard, are not supported on older versions of Android.

Material Design

Material Design (codenamed Quantum Paper) is a design language that Google developed in 2014. Expanding on the "card" motifs that debuted in Google Now, Material Design uses more grid-based layouts, responsive animations and transitions, padding, and depth effects such as lighting and shadows.

Google announced Material Design on June 25, 2014, at the 2014 Google I/O conference.

Nexus 7 (2012)

The first-generation Nexus 7 is a mini tablet computer co-developed by Google and Asus that runs the Android operating system. It is the first tablet in the Google Nexus series of Android consumer devices marketed by Google and built by an original equipment manufacturer partner. The Nexus 7 features a 7-inch (180 mm) display, an Nvidia Tegra 3 quad-core chip, 1 GB of memory, Wi-Fi and near field communication connectivity, and 8, 16 or 32 GB of storage. The tablet was the first device to ship with version 4.1 of Android, nicknamed "Jelly Bean". By emphasizing the integration of the Google Play multimedia store with Android 4.1, Google intended to market the Nexus 7 as an entertainment device and a platform for consuming e-books, television shows, films, games, and music.

Design work on the Nexus 7 began in January 2012 after a meeting between Google and Asus executives at International CES. The device's design was based on Asus' Eee Pad MeMO ME370T tablet that had been showcased at the conference. Following a hectic four-month development period during which the device was modified to reach a US$199 price point, mass production started in May. It was unveiled at the Google I/O annual developer conference on June 27, when it also became available for pre-order through Google Play. Shipping commenced in mid-July 2012 to Australia, Canada, the United States, and the United Kingdom, before the tablet was progressively released in other regions. Google expanded the Nexus 7 lineup in October 2012 with the introduction of 32 GB versions, available in Wi-Fi–only and HSPA+ cellular-ready varieties.

The Nexus 7 received positive reviews from critics, particularly for its competitive pricing, premium-quality build, and powerful hardware. Common criticisms included the absence of cellular connectivity from initial models and no expandable storage. The Nexus 7 has been commercially successful, selling approximately 4.5–4.6 million units in 2012 and 7 million units overall. It received honors for "Gadget of the Year" and "Tablet of the Year" in T3 magazine's 2012 awards, and was also named "Best Mobile Tablet" at the 2013 Global Mobile Awards. The second generation Nexus 7 was released on July 26, 2013.

Nexus Q

Nexus Q is a digital media player developed by Google. Unveiled at the Google I/O developers' conference on June 27, 2012, the device was expected to be released to the public in the United States shortly thereafter for US$300. The Nexus Q was designed to leverage Google's online media offerings, such as Google Play Music, Google Play Movies & TV, and YouTube, to provide a "shared" experience. Users could stream content from the supported services to a connected television, or speakers connected to an integrated amplifier, using their Android device and the services' respective apps as a remote control for queueing content and controlling playback.

The Nexus Q received mixed reviews from critics following its unveiling. While its unique spherical design was praised, the Nexus Q was criticized for its lack of functionality in comparison to similar devices such as Apple TV, including a lack of support for third-party content services, no support for streaming content directly from other devices using the DLNA standard, as well as other software issues that affected the usability of the device. The unclear market positioning of the Nexus Q was also criticized, as it carried a significantly higher price than competing media players with wider capabilities; The New York Times' technology columnist David Pogue described the device as being 'wildly overbuilt' for its limited functions.The Nexus Q was given away at no cost to attendees of Google I/O, but the product's consumer launch was indefinitely postponed the following month, purportedly to collect additional feedback. Those who had pre-ordered the Nexus Q following its unveiling received the device at no cost. The Nexus Q was quietly shelved in January 2013, and support for the device in the Google Play apps was phased out beginning in May 2013. Some of the Nexus Q's concepts were repurposed for a more-successful device known as Chromecast, which similarly allows users to wirelessly queue content for playback using functions found in supported apps, but is designed as a smaller HDMI dongle with support for third-party services.


ShareTheMeal is a crowdfunding smartphone application to fight global hunger through the United Nations World Food Programme (WFP). It enables users to make small donations to specific WFP projects and to track its progress.
