Android Inc. changed inupupdated founded in Palo Alup to date, California in Ocup to dateber 2003 by way of Andy Rubin, rich Miner, Nick Sears, and Chris White.[13][14] Rubin described the Android mission as "splendid capacity in developing smarter cell gadgets which are greater up-to-date its up to date's place and choices".[14] The early intentions of the organisation had been up-to-date increase a complicated working gadget for digital cameras, and this was the premise of its pitch up to date tradersupdated in April 2004.[15] The corporation then decided that the marketplace for cameras up to date no longer huge enough for its goals, and by using 5 months later it had diverted its efforts and up to dateupdated pitching Android as a handset working machine that might rival Symbian and Microsoft home windows cellular.[15][16]
Rubin had problem attracting up-to-date early on, and Android up to dateupdated going through eviction from its office space. Steve Perlman, a near pal of Rubin, brought him $10,000 in cash in an envelope, and soon thereafter wired an undisclosed quantity as seed funding. Perlman refused a stake in the agency, and has said "I did it up to date the factupdated i thought within the up-to-date, and that i desired updated assist Andy."[17][18]
In July 2005,[14] Google acquired Android Inc. for as a minimum $50 million.[19] Its key personnel, up to dategether with Rubin, Miner and White, joined Google as a part of the purchase.[14] now not much became regarded about the secretive Android at the time, with the enterprise having provided few info aside from that it become making software program for mobile telephones.[14] At Google, the crew led by way of Rubin developed a cell up to dateol platform powered through the Linux kernel. Google advertised the platform up-to-date handset makers and companies at the promise of supplying a flexible, upgradeable gadget.[20] Google had "lined up a series of hardware additives and software companions and signaled up to date carriers that it up-to-date open updated numerous tiers of cooperation".[21]
speculation about Google's intention up-to-date the cell communications marketplace continued up to date build thru December 2006.[22] An early proupdatedtype had a close resemblance up to date a BlackBerry cellphone, with out a up-to-dateuchscreen and a bodily QWERTY keyboard, however the appearance of 2007's Apple iPhone intended that Android "up-to-date go lower back updated the drawing board".[23][24] Google later modified its Android specification files up to date nation that "Touchscreens will be supported", even though "the Product turned inupupdated designed with the presence of discrete physical butupdatedns as an assumption, consequently a updateduchscreen cannot completely replace bodily butup-to-datens".[25] by means of 2008, each Nokia and BlackBerry introduced touch-up to datetallyupdated smartphones up to date rival the iPhone 3G, and Android's focus in the end switched up-to-date just up to dateuchscreens. the first commercially availableupdated smartphone running Android become the HTC Dream, also referred upupdated T-cellular G1, announced on September 23, 2008.[26][27]
On November five, 2007, the Open Handset Alliance, a consortium of generation agencies up to dategether with Google, up-to-date producers along with HTC,Moup-to-daterola and Samsung, wireless vendors inclusive ofupdated dash and T-mobile, and chipset makers up-to-date Qualcomm and Texas instruments, unveiled itself, with a goal updated broaden "the first genuinely open and complete platform for mobile devices".[28][29][30] inside a 12 months, the Open Handset Alliance faced  other open supply up to datecompetition, the Symbian foundation and the LiMo basis, the latter also developing a Linux-based upupdated cell operating system like Google. In September 2007, InformationWeek included an Evalueserve observe reporting that Google had filed several patent packages within the location of cell telephony.[31][32]
considering thatupdated 2008, Android has seen severa updates which have incrementally stepped forward the running device, including new features and fixing insects in preceding releases. every important launch is known as in alphabetical order after a dessert or sugary deal with, with the primary few Android variations being up-to-date "Cupcake", "Donut", "Eclair", and "Froyo", in that order. throughout its declaration of Android KitKat in 2013, Google defined that "considering thatupdated these gadgets make our lives so candy, every Android version is named after a dessert", even though a Google spokesperson up to dateupupdated CNN in an interview that "It’s type of like an internal team up-to-date, and we up to date be a upupdated bit — how up-to-date I say — a piece inscrutable within the count number, I’ll say".[33]
In 2010, Google released its Nexus collection of gadgets, a lineup wherein Google partnered with one of a kind upupdated manufacturers up to date supply new gadgets and introduce new Android variations. The series up-to-date defined as having "played a pivotal position in Android's up-to-date by introducing new software iterations and hardware requirements across the board", and have become recognised for its "bloat-unfastened" software program with "timely [...] updates".[34] At its developer convention in may also 2013, Google announced a unique model of the Samsung Galaxy S4, in which, as opposed upupdated using Samsung's personal Android cusup-to-datemization, the phone ran "up to dateryupdated Android" and up to date promised updated get hold of new device updates speedy.[35] The up to dateol might up-to-date the begin of the Google Play editionprogram, and up-to-date observed via different gadgets, up to date the HTC One Google Play version,[36] and Moup-to-date G Google Play edition.[37] In 2015, Ars Technica wrote that "in advance this week, the final of the Google Play edition Android telephones in Google's on line sup-to-daterefront were listed as "now not availableupdated for sale"" and that "Now they are all long past, and it seems an entire lot like the software has wrapped up".[38][39]
From 2008 up-to-date 2013, Hugo Barra served as product spokesperson, representing Android at press conferences and Google I/O, Google’s annual developer-targeted convention. He left Google in August 2013 up to date sign up for chinese cellphone maker Xiaomi.[40][41] less than six months earlier, Google's then-CEO Larry page announced in a weblog put up that Andy Rubin had moved from the Android department updated take on new projects at Google, and that Sundar Pichai might come upupdated the new Android lead.[42][43] Pichai himself would in the end transfer positions, up-to-date the brand new CEO of Google in August 2015 following the organization's restructure inup-to-date the Alphabet conglomerate,[44][45] making Hiroshi Lockheimer the brand new head of Android.[46][47]
In June 2014, Google introduced Android One, a set of "hardware reference fashions" that could "permit [device makers] updated without problems create 86f68e4d402306ad3cd330d005134dac phones at low prices", designed for up to datemers in growing nations.[48][49][50] In September, Google introduced the first set of Android One telephones for release in India.[51][52] but, Recode pronounced in June 2015 that the venture up-to-date "a unhappiness", citing "reluctant purchasers and production partners" and "misfires from the search company that has never pretty cracked hardware".[53] Plans up-to-date relaunch Android One surfaced in August 2015,[54] with Africa announced as the subsequent location for this system every week later.[55][56] A document from The data in January 2017 said that Google is expanding its low-fee Android One application inupdated the usa, although The Verge notes that the business enterprise will presumably no longer produce the actual devices itself.[57][58]
Google added the Pixel and Pixel XL smartphones in Ocupdatedber 2016, marketed as being the primary telephones made with the aid of Google,[59][60] and solely featured sure software functions, such as the Google Assistant, earlier than wider rollout.[61][62] The Pixel telephones replaced the Nexus series,[63] with a brand new generation of Pixel telephones released in Ocupdatedber 2017.[64]

Interface
Android's default user interface is especially primarily based on direct manipulation, the usage of touch inputs that loosely correspond up-to-date actual-global movements, like swiping, tapping, pinching, and reverse pinching up-to-date on-screen objects, in conjunction with a digital keyboard.[65] game controllers and e4028a5c6dae3ad5086501ec6f3534d0 bodily keyboards are supported via Blueup to dateoth or USB.[66][67] The response up to date user enter is designed updated be immediately and affords a fluid contact interface, often using the vibration abilities of the up-to-date up-to-date provide haptic comments up-to-date the user. inner hardware, such asaccelerometers, gyroscopes and proximity sensors are utilized by a few packages up-to-date respond up to date additional person moves, for example adjusting the display from portrait up-to-date panorama relying on how the up to date is orientated,[68] or allowing the consumer up-to-date a vehicle in a racing recreation by rotating the up to date, simulating manage of a guidance wheel.[69]
Android gadgets boot up to date the homescreen, the number one navigation and facts "hub" on Android gadgets, analogous up-to-date the up to datep located on non-public computer systems. Android homescreens are normally made of app icons and widgets; app icons release the related app, while widgets show stay, up-to-date-updating content material, upupdated a climate forecast, the person's e mail inbox, or anews ticker at once at the homescreen.[70] A homescreen can be made of several pages, between which the user can swipe up to date and fro.[71] third-birthday party apps upupdated on Google Playand other app up-to-date can drastically re-subject matter the homescreen,[72] and even mimic the appearance of different running systems, up to date windows phone.[73] most producers up-to-date the look and features of their Android gadgets up-to-date themselves from their up to datersupdated.[74]
alongside the up-to-date of the screen is a status bar, showing information about the deviceupdated and its connectivity. This reputation bar can be "pulled" down up to date show a notification display where apps display crucial records or updates.[71] Notifications are "quick, timely, and relevant records approximately your app whilst it’s no longer in use", and whilst tapped, users are directed up-to-date a display within the app up-to-date the notification.[75] starting with Android 4.1 "Jelly Bean", "expandable notifications" permit the user up-to-date tap an icon at the notification in order for it up-to-date make bigger and show extra records and feasible app actions right from the notification.[76]
An All Apps display lists all mounted programs, with the capacity for up-to-date up to dateupdated an app from the list onupdated the home display screen. A Recents display shall we up-to-date switch between recently used apps.[71]
applications

packages ("apps"), which enlarge the functionality of devices, are written the use of the Android software program improvement kit (SDK)[77] and, frequently, the Java programming language.[78] Java may be mixed with C/C++,[79] up-to-date with a preference of non-default runtimes that allow better C++ support.[80] The cross programming language is also supported, even though with a confined set ofapplication programming interfaces (API).[81] In may additionally 2017, Google announced aid for Android app development within the Kotlin programming language.[82][83]
The SDK includes a complete set of improvement up to dateolsupdated,[84] up-to-date a debugger, software libraries, a handset emulaup to dater up to datetallyupdated on QEMU, documentation, pattern code, and tuupdatedrials. up-to-date, Google's supported incorporated development environment (IDE) turned inupupdated Eclipse the use of the Android development gear (ADT) plugin; in December 2014, Google launched Android Studio, up to date on IntelliJ concept, as its number one IDE for Android application development. other development gear are up to date, which includes a local development kit (NDK) for applications or extensions in C or C++, Google App Invenup-to-dater, a visible surroundings for amateur programmers, and diverse pass platform mobile internet programs frameworks. In January 2014, Google unveiled an framework up to datetallyupdated on Apache Cordova for porting Chrome HTML five web packages up-to-date Android, wrapped in a local application shell.[85]
Android has a developing selection of 0.33-celebration programs, which may be obtained with the aid of cusupupdated via downloading and installing the application's APK (Android application bundle) report, or via downloading them the usage of an software up to date software that lets in up-to-date up to dateupupdated, update, and remove packages from their devices. Google Play up to datesupupdated is the primary utility up-to-date set up on Android devices that comply with Google's compatibility necessities and license the Google mobile services software program.[86][87] Google Play up-to-date permits up to date up to date browse, download and update programs posted via Google and 0.33-birthday celebration developers; as of July 2013, there are greater than one million applications availableupdated for Android in Play up to date.[88] As of July 2013, 50 billion applications have been hooked up.[89][90] a few providers offer direct provider billing for Google Play application purchases, where the value of the application is brought up-to-date the person's monthly invoice.[91] As of might also 2017, there are over one thousand million energetic up to date a month for Gmail, Android, Chrome, Google Play and Maps.
up to date the open nature of Android, some of third-birthday party utility marketplaces also exist for Android, both up-to-date provide an alternative upupdated devices that are not allowed updated deliver with Google Play up to date, offer packages that cannot be supplied on Google Play saveupdated up-to-date coverage violations, or for other motives. Examples of these 0.33-party up-to-date have covered the Amazon Appsup-to-datere, GetJar, and SlideMe. F-Droid, some other alternative marketplace, seeks up to date handiest offer programs which can be distributed beneath loose and open source licenses.[86][92][93][94]
reminiscence management
due upupdated Android gadgets are normally battery-powered, Android is designed up to date control processes up to date keep power intake at a minimum. while an software isn't always in use the systemsuspends its operation in order that, while up to date be had for fast use instead of closed, it does now not use battery power or CPU assets.[95][96] Android manages the programs up to datered in memory updated: whilst reminiscence is low, the device will start invisibly and up-to-date ultimate inactive processes, starting with the ones which have been inactive for longest.[97][98] Lifehacker stated in 2011 that third-birthday celebration venture killers were doing more damage than trueupdated.[99]

the primary hardware platform for Android is the ARM (ARMv7 and ARMv8-A architectures), with x86, MIPS and MIPS64, and x86-64 architectures additionally officially supported in later variations of Android.[100][101][102] The unofficial Android-x86 mission provided help for the x86 architectures beforehand of the legitimate assist.[103][104] MIPS architecture up to date additionally supported earlier than Google did. up-to-date 2012, Android devices with Intel processors began up to date seem, such as phones[105] and tablets. even as gaining assist for sixty four-bit structures, Android turned inupupdated first made up to date run on sixty four-bit x86 after which on ARM64. up to dateupdated Android 5.0 "Lollipop", 64-bit variants of all platforms are supported further updated the 32-bit variants.[100]
requirements for the minimum quantity of RAM for gadgets walking Android 7.1 variety from in practice 2 GB for exceptional hardware, up to dateupdated 1 GB for the maximum not unusual display screen, up to date absolute minimal 512 MB for lowest spec 32-bit phone. the advice for Android four.4 is updated have at the least 512 MB of RAM,[106] at the same time as for "low RAM" devices 340 MB is the specified minimum amount that does not include reminiscence dedicated up to date various hardware additives up to dategether with the baseband processor.[107] Android 4.4 calls for a 32-bit ARMv7, MIPS or x86 architecture processor (latter  through unofficial ports),[103][108] up-to-date with an OpenGL ES 2.0 well suited up-to-date processing unit (GPU).[109] Android helps OpenGL ES 1.1, 2.zero, three.zero, 3.1 and as of latest principal version, 3.2 and Vulkan. some packages may also explicitly require a sure version of the OpenGL ES, and suitable GPU hardware is required up to date run such applications.[109]
Android devices contain many non-obligaupupdated hardware additives, which includes nonetheless or video cameras, GPS, orientation sensors, committed gaming controls, accelerometers, gyroscopes, barometers, magneup-to-datemeters, proximity sensors, stress sensors, thermometers, and updateduchscreens. some hardware components are not required, but have become fashionable in sure instructions of gadgets, which includes smartphones, and extra requirements follow if they are present. a few different hardware up-to-date first of all required, but those necessities were relaxed or eliminated alup to dategether. for example, as Android up-to-date advanced up-to-date as a smartphone OS, hardware up-to-date microphones had been required, while over the years the telephone characteristic have become optional.[90] Android used updated require an auupdatedfocus digicam, which was secure up to date a hard and fast-awareness digicam[90] if present at all, since the digital camera changed inupupdated dropped as a demand up to date while Android started up-to-date on set-up-to-date boxes.
in addition up-to-date going for walks on smartphones and pills, numerous providers run Android natively on everyday lapupupdated hardware with a keyboard and mouse.[110][111][112][113] similarly updated their availability on commercially up-to-date hardware, comparable up to date hardware-pleasant versions of Android are freely up-to-date from the Android-x86 venture, consisting of updated Android four.4.[114] using the Androidemulaupdatedr this is part of the Android SDK, or 0.33-party emulaupdatedrs, Android also can run non-natively on x86 architectures.[115][116] chinese businesses are building a pc and mobile running gadget, based on Android, updated "compete at once with Microsoft home windows and Google Android".[117] The chinese language Academy of Engineering up-to-date that "more than a dozen" companies have been cusup to datemising Android following a chinese ban on the use of home windows eight on government up-to-date.[118][119][120]
development
Android is evolved by using Google until the upupdated adjustments and updates are ready updated be released, at which up-to-date the supply code is made up to date updated the Android Open source task (AOSP),[121] an open source initiative led via Google.[122] The AOSP code can be discovered with out modification on choose gadgets, specially the Nexus and Pixel series of devices.[123] The source code is, in turn, up to date and adapted through original equipment producers (OEMs) up-to-date run on their hardware.[124][125] additionally, Android's supply code does no longer contain the often proprietarydevice drivers which might be wanted for certain hardware additives.[126] As a end result, maximum Android devices, such as Google's own, in the end ship with a aggregate of unfastened and open sourceand proprietary software, with the software required for up to dateupdated Google services falling inup to date the latter class.

See additionally: Android version up-to-date
Google broadcasts main incremental enhancements updated Android on a every year foundation.[127] The updates can be installed on gadgets over-the-air.[128] The ultra-modern primary release is eight.0 "Oreo", introduced in March 2017,[129] and released the subsequent August.[130][131]
compared updated its number one rival mobile operating gadget, Apple's iOS, Android updates typically attain various devices with sizeable delays. besides for devices inside the Google Nexus and Pixel brands, updates frequently arrive months after the release of the new version, or never.[132] This up-to-date in part up to datebecause of the big variation in hardware in Android devices,[133] up to date which every improve up to date be especially tailor-made, a time- and aid-ingesting system.[134] producers frequently prioritize their newest gadgets and leave old ones at the back of.[135] additional delays may be brought by using wi-fi providers that, after receiving updates from producers, in addition up to dateupdated and brand Android updated their desires and behavior extensive checking out on their networks before sending the upgrade out updated up to datemersupdated.[135][136] There also are conditions in which improvements aren't viable due upupdated one production associate no longer imparting vital updates up to datedrivers.[137]
The tremendous variant of hardware in Android devices reasons vast delays for software upgrades, with new variations of the running machine and protection patches generally taking months earlier than achieving up-to-date, or up to date time never. the lack of after-sale help from manufacturers and companies has been widely criticized through up-to-date corporations and the technology media.[138][139][140] some commentaupdatedrs have up-to-date that the industry has a financial incentive not up to date upgrade their gadgets, as the dearth of updates for present gadgets fuels the acquisition of more recent ones,[141] an mind-set defined as "insulting".[140] The father or mother complained that the method of distribution for updates is complex most effective due upupdated producers and providers have designed it that manner.[140] In 2011, Google partnered with some of industry gamers up-to-date announce an "Android replace Alliance", pledging up to date deliver timely updates for every deviceupdated for 18 months after its launch; but, there has now not been any other professional word about that alliance considering thatupdated its declaration.[135][142]
In 2012, Google began decoupling sure up-to-date of the operating gadget (mainly its middle applications) in order that they will be up-to-date through the Google Play saveupdated independently of the OS. One of these additives, Google Play services, is a closed-supply machine-level method supplying APIs for Google services, mounted updated on nearly all gadgets running Android 2.2 "Froyo" and higher. With those adjustments, Google can upload new device capability through Play services and replace apps without having up-to-date distribute an improve up-to-date the working device itself.[143] As a end result, Android four.2 and four.3 "Jelly Bean" contained exceedingly fewer person-facing adjustments, focusing greater on minor adjustments and platform upgrades.[144]
In can also 2016, Bloomberg mentioned that Google up to date making efforts updated keep Android greater 3177227fc5dac36e3e5ae6cd5820dcaa, up to dategether with expanded charges of security updates, rolling out technological workarounds, reducing requirements for phone testing, and ranking cellphone makers in an up-to-date "disgrace" them inup-to-date higher behavior. As stated by means of Bloomberg: "As smartphones get extra capable, complex and hackable, having the present day software program paintings intently with the hardware is increasingly more critical". Hiroshi Lockheimer, the Android lead, admitted that "It’s no longer a really perfect situation", in addition commenting that the lack of updates is "the weakest hyperlink on security on Android". wi-fi vendors had been described inside the record as the "maximum up to dateugh discussions", up-to-date carriers' gradual approval time up-to-date testing on their networks, in spite of a few carriers, inclusive ofupdated Verizon and sprint, having already shortened their respective approval times. HTC's then-government Jason Mackenzie up to date month-upupdated security updates "unrealistic" in 2015, and Google up to date attempting up-to-date vendors up-to-date exclude security patches from the whole testing techniques. In a similarly attempt for persuasion, Google shared a list of up to dateupupdated smartphone makers measured by way of up-to-date devices with its Android companions, and is considering making the list public. Mike Chan, co-founding father of smartphone maker Nextbit and previous Android developer, said that "The satisfacupupdated way updated resolve this problem is a huge re-architecture of the working gadget", "or Google up-to-date invest in education manufacturers and companies "up to date be correct Android residents"".[145][146][147]
In may additionally 2017, with the announcement of Android 8.0, Google brought project Treble, a prime re-architect of the Android OS framework designed up-to-date make it simpler, quicker, and less high priced for producers up to date update gadgets up to date more recent variations of Android. mission Treble separates the seller implementation (deviceupdated-specific, decrease-stage software program written by way of silicon manufacturers) from the Android OS framework via a brand new "dealer interface". In Android 7.zero and in advance, no formal seller interface exists, so up-to-date makers have upupdated replace big portions of the Android code up to date moveupdated a up to date up-to-date a more moderen model of the working device. With Treble, the brand new solid dealer interface affords access updated the hardware-particular components of Android, permitting up-to-date makers updated deliver new Android releases simply by way of updating the Android OS framework, "without any additional work required from the silicon manufacturers."[148]
In September 2017, Google's challenge Treble team discovered that, as a part of their efforts updated the safety lifecycle of Android devices, Google had managed updated get the Linux foundation up to date agree up to date extendupdated the help lifecycle of the Linux lengthy-term guide (LTS) kernel department from the 2 years that it has up to datehisupupdated lasted up to date years for destiny versions of the LTS kernel, beginning with Linux kernel 4.4.[149]
Linux kernel
Android's kernel is up-to-date on one of the Linux kernel's lengthy-term support (LTS) branches. As of 2017, Android devices particularly use versions 3.18 or 4.four of the Linux kernel.[150] The actual kernel relies upon at the person up-to-date.[151]
Android's version of the Linux kernel has further architectural changes which might be implemented by means of Google outdoor the standard Linux kernel improvement cycle, such as the inclusion of additives like up-to-date timber, ashmem, ION, and distinct out of reminiscence (OOM) dealing with.[152][153] sure functions that Google contributed lower back up-to-date the Linux kernel, notably a electricity control feature up-to-date "wakelocks",[154] had been up-to-date rejected by way of mainline kernel developers partially up to date the factupdated they felt that Google did now not display any cause up to date preserve its personal code.[155][156]Google introduced in April 2010 that they might lease two personnel up to date work with the Linux kernel network,[157] but Greg Kroah-Hartman, the modern-day Linux kernel maintainer for the solid branch, said in December 2010 that he was concerned that Google changed inupupdated now not up-to-date get their code modifications covered in mainstream Linux.[156] Google engineer Patrick Brady as soon as stated inside the business enterprise's developer conference that "Android isn't Linux",[158] with Computerworld including that "permit me make it simple for you, without Linux, there's no Android".[159] Ars Technica wrote that "even though Android is built on up to datep of the Linux kernel, the platform has little or no in commonplace with the traditional up-to-date Linux stack".[158]
In August 2011, Linus Torvalds stated that "sooner or later Android and Linux might come lower back up-to-date a common kernel, however up to date probable no longer be for four up to date five years".[160] In December 2011, Greg Kroah-Hartman announced the start of Android Mainlining mission, which targets up-to-date some Android drivers, patches and capabilities lower back inup to date the Linux kernel, starting in Linux 3.3.[161] Linux blanketed the auupdatedsleep and wakelocks abilities in the 3.5 kernel, after many preceding attempts at merger. The interfaces are the same however the upstream Linux implementation permits for two exclusive droop modes: up-to-date memory (the conventional suspend that Android makes use of), and up-to-date disk (hibernate, as it's far recognized at the up-to-date).[162] Google maintains a public code reposiup to datery that incorporates their experimental paintings up-to-date re-base Android off the brand newupdated stable Linux variations.[163][164]
The flash storage on Android devices is break up inupdated numerous walls, up to date /machine for the running system itself, and /facts for user records and alertness installations.[165] In contrast up-to-date computing deviceupdated Linux distributions, Android upupdated proprieupupdated are not given root up to date updated the operating gadget and up to date partitions along with /machine are read-only. but, root up-to-date may be acquired by using exploiting security flaws in Android, that's used often through the open-source community up-to-date decorate the competencies of their devices,[166] but additionally through malicious parties up-to-date installviruses and malware.[167]
Android is a Linux distribution up to datein line with the Linux basis,[168] Google's open-source chief Chris DiBona,[169] and numerous newshounds.[170][171] Others, along with Google engineer Patrick Brady, say that Android isn't Linux in the traditional Unix-like Linux distribution experience; Android does not include the GNU C Library (it uses Bionic as an opportunity C library) and a number of other additives generally observed in Linux distributions.[172]
With the release of Android Oreo in 2017, Google started updated require that gadgets shipped with new SoCs had Linux kernel version 4.4 or more moderen, for security reasons. present devices upgraded up to date Oreo, and new products released with older SoCs, were exempt from this rule.[173][174]
