Android is a mobile operating system developed by Google. Android is based on a modified version of the Linux kernel and other open source software, and is designed primarily for touch screen mobile devices such as smartphones and tablets. Version history of the Android operating system begins with the release of Android 1.0 beta in November 2007. Since April 2009, every version of Android that has been developed is then released under a code name based on dessert items.
Android Version 1.0 - 1.1
Android was officially released to the public on September 23, 2008 under the name Android 1.0. The features were very basic at the time, but the software did include a series of early Google applications such as Gmail, Maps, Calendar and YouTube, all of which were integrated into the operating system.
Android version 1.5: Cupcake
Android 1.5 Cupcake was released in early April 27, 2009, then the tradition of naming the Android version was born. Cupcake introduces many improvements to the Android interface, including an on-screen keyboard. Something new from the physical keyboard model that at the time was very much. Cupcake also presents a framework for third-party application widgets, which later became one of the Android elements that most distinguishes it from other operating systems.
Android version 1.6: Donut
Android 1.6, Donut, rolled into the world on September 15, 2009. Donut fills several important holes in the center of Android, including the ability of the OS to operate at different screen sizes and resolutions - a very important factor in the coming years. It also added support for CDMA networks such as Verizon, which will play a key role in the upcoming Android explosion.
Android versions 2.0 to 2.1: Eclair
Following the very fast release rate of the early years of Android, Android 2.0 Eclair appeared just six weeks after Donut. Precisely released on October 26, 2009. The "point-one" update, named Eclair, came out a few months later. The most transformative update is the addition of voice-guided navigation and real-time traffic info. Something that had never before existed in the smartphone world. In addition to navigation, Eclair brings live wallpaper to Android as well as the first speech-to-text function on this platform. Adding pinch-to-zoom capability to Android is a big step here.
Android version 2.2: Froyo
Just four months after Android 2.1, Google presents Android 2.2, Froyo (May 20, 2010), where there is a major update on improving operating system performance. Froyo does provide several important features including the addition of a standard dock at the bottom of the home screen. Froyo also brings support for Flash to the Android web browser.
Android version 2.3: Gingerbread
The visual identity of Android begins to be in focus with the release of Gingerbread on December 6, 2010. Bright green has long been the color of the Android robot mascot, and with Gingerbread, this color has become an integral part of the operating system's appearance. Black and green are used almost throughout the UI a step towards a distinctive design.
Android 3.0 to 3.2: Honeycomb
The Honeycomb 2011 period is a strange time for Android to be released on February 22, 2011. Android 3.0 appears in the world as a special release for tablets just as the Motorola Xoom launches, and through subsequent 3.1 and 3.2 updates, it remains an exclusive tablet entity (and closed source).
Android version 4.0: Ice Cream Sandwich
Honeycomb acts as a bridge from the old to the new, Ice Cream Sandwich, released on October 18, 2011 to function as an official platform entry into the modern design era. This release perfected the visual concept introduced with Honeycomb and reunited tablets and phones with one single UI vision.
Android versions 4.1 to 4.3: Jelly Bean
Spread over three influential versions of Android, the release of Jelly Bean on July 9 2012 took the foundation of ICS. In addition to visuals, Jelly Bean presents the first taste of Google Now. Multiuser support is also coming. Jelly Bean is an excellent system for placing widgets on your screen.
Android version 4.4: KitKat
The KitKat release on 31 October 2013 marked the end of the dark era of Android. There are many updates to the UI and transparent icons give the OS a more contemporary look. Android 4.4 is also the first version of "OK, Google". But on KitKat, confirmation of handsfree activation only works when your screen is on and you are on the home screen or in the Google application.
Android versions 5.0 and 5.1: Lollipop
Google basically reinvented the new Android with the release of Android 5.0 Lollipop on November 12, 2014. Lollipop launched the Material Design standard that still exists today, which brings a new look that extends to all applications. Lollipop introduces many new features to Android, including handsfree voice control via the command "OK, Google", support for many users on mobile and priority mode for better notification management.
Android version 6.0: Marshmallow
Marshmallow (October 5, 2015) is a fairly small Android release. But that started the trend Google released one major Android version per year and that version always received initial numbers from the version. The element that most caught Marshmallow's attention was the screen search feature called Now On Tap. Something that has a lot of potential that hasn't been fully utilized. Google has never been satisfied enough to perfect the system. Android 6.0 does introduce a number of things with wide impact, including more detailed application permissions, support for fingerprint readers and support for USB-C.
Android versions 7.0 and 7.1: Nougat
The release of Android Nougat Android 22 August 2016 provides the first Android split-screen, a new bundle-by-app system for managing notifications and data saver features. Nougat added a number of smaller but still significant features, such as shortcuts like Alt-Tab for taking pictures between applications. Google Assistant comes along with the announcement of Google's mobile phone, which is Pixel. About two months after Nougat's debut.
Android versions 8.0 and 8.1: Oreo
Android Oreo adds a variety of variations to this platform, including picture-in-picture mode, snooze notification options and notification channels that offer much better control. The release on August 21, 2017 also includes several important elements that continue Google's goal to harmonize Android and Chrome OS and improve the experience of using the Android application on a Chromebook. Oreo became the first Android to feature Project Treble, an ambitious effort to create a modular base.
Android version 9.0: Pie
Android 9 has many important productivity features, including a universal suggestion-answering system for messaging notifications, a more effective screenshot management method, and a smarter system for power management and screen brightness control. Wi-Fi hotspot handling features, as well as finger touch which is useful for fingerprint sensors. Pie uses visual tweak sections, such as an updated notification display and Quick Settings panel next to it and a series of additional animations throughout the interface
