Glass was updating by itself automatically over the air. Glass was checking Google servers periodically for updates. When an update was available, Glass was downloading it to the device and was installing the update all by itself. That was happening under the condition of active battery charging and a reliable Wi-Fi connection. [10]
A Bluetooth stack is software that is an implementation of the Bluetooth protocol stack.
Android is a mobile operating system based on a modified version of the Linux kernel and other open-source software, designed primarily for touchscreen mobile devices such as smartphones and tablets. Android is developed by a consortium of developers known as the Open Handset Alliance, though its most widely used version is primarily developed by Google. It was unveiled in November 2007, with the first commercial Android device, the HTC Dream, being launched in September 2008.
License compatibility is a legal framework that allows for pieces of software with different software licenses to be distributed together. The need for such a framework arises because the different licenses can contain contradictory requirements, rendering it impossible to legally combine source code from separately-licensed software in order to create and publish a new program. Proprietary licenses are generally program-specific and incompatible; authors must negotiate to combine code. Copyleft licenses are commonly deliberately incompatible with proprietary licenses, in order to prevent copyleft software from being re-licensed under a proprietary license, turning it into proprietary software. Many copyleft licenses explicitly allow relicensing under some other copyleft licenses. Permissive licenses are compatible with everything, including proprietary licenses; there is thus no guarantee that all derived works will remain under a permissive license.
A mobile operating system is an operating system used for smartphones, tablets, smartwatches, smartglasses, or other non-laptop personal mobile computing devices. While computers such as typical/mobile laptops are "mobile", the operating systems used on them are generally not considered mobile, as they were originally designed for desktop computers that historically did not have or need specific mobile features. This line distinguishing mobile and other forms has become blurred in recent years, due to the fact that newer devices have become smaller and more mobile unlike hardware of the past. Key notabilities blurring this line are the introduction of tablet computers, light-weight laptops, and the hybridization of the two in 2-in-1 PCs.
iOS is a mobile operating system developed by Apple Inc. exclusively for its smartphones. It was unveiled in January 2007 for the first-generation iPhone, launched in June 2007.
Bada is a discontinued mobile operating system developed by Samsung Electronics for devices such as mid- to high-end smartphones and tablet computers. The name is derived from "바다 (bada)", meaning "ocean" or "sea" in Korean. All phones running Bada were branded with the name Wave, unlike Samsung's Android devices which are branded as Galaxy.
Bionic is an implementation of the standard C library, developed by Google for its Android operating system. It differs from the GNU C Library (glibc) in being designed for devices with less memory and processor power than a typical Linux system. It is a combination of new code and code from FreeBSD, NetBSD, and OpenBSD released under a BSD license, rather than glibc, which uses the GNU Lesser General Public License. This difference was important in the early days of Android, when static linking was common, and since bionic has its own ABI, it can't be replaced by a different libc without breaking all existing apps.
Sailfish OS is a Linux-based operating system based on free software, and open source projects such as Mer as well as including a closed source UI. The project is being developed by the Finnish company Jolla.
AOKP, short for Android Open Kang Project, is an open-source replacement distribution for smartphones and tablet computers based on the Android mobile operating system. The name is a play on the word kang and AOSP. The name was a joke, but it stuck. It was started as free and open-source software by Roman Birg based on the official releases of Android Open Source Project by Google, with added original and third-party code, features, and control.
Wear OS is a version of Google's Android operating system designed for smartwatches and other wearables. By pairing with mobile phones running Android version 6.0 "Marshmallow" or newer, or iOS version 10.0 or newer with limited support from Google's pairing application, Wear OS integrates Google Assistant technology and mobile notifications into a smartwatch form factor. Wear OS is closed-source, in contrast to the free and open-source Android.
The Nokia X platform was a Linux-based mobile operating system and software platform originally developed by Nokia, and subsequently by Microsoft Mobile. Introduced on 24 February 2014, it was forked from Android and used on all the devices of the Nokia X family. It was also the next Nokia Linux project after the ill-fated MeeGo.
Android Lollipop is the fifth major version of the Android mobile operating system developed by Google and the 12th version of Android, 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. Its source code was made available on November 3, 2014. The first phone with Android Lollipop was the Nexus 6.
Fira OS is a Linux-based mobile operating system and software platform developed by Fira, a subsidiary of Indonesian electronic giant Polytron. Introduced on January 28, 2016, it was forked from Android and installed on newer Polytron smartphones since 2016.
Android Nougat is the seventh major version and 14th original version of the Android operating system. First released as an alpha test version on March 9, 2016, it was officially released on August 22, 2016, with Nexus devices being the first to receive the update. The LG V20 was the first smartphone released with Nougat.
Fuchsia is an open-source capability-based operating system developed by Google. In contrast to Google's Linux-based operating systems such as ChromeOS and Android, Fuchsia is based on a custom kernel named Zircon. It publicly debuted as a self-hosted git repository in August 2016 without any official corporate announcement. After years of development, its official product launch was in 2021 on the first-generation Google Nest Hub, replacing its original Linux-based Cast OS.
Android Oreo is the eighth major release and the 15th version of the Android mobile operating system. It was initially unveiled as an alpha quality developer preview in March 2017 and later made available to the public, on August 21, 2017.
postmarketOS is an operating system primarily for smartphones, based on the Alpine Linux distribution.
One UI is a user interface (UI) developed by Samsung Electronics for its Android devices running Android 9 "Pie" and later. Succeeding Samsung Experience and TouchWiz, it is designed to make using larger smartphones easier and be more visually appealing. To provide more clarity, some elements of the UI are tweaked to match colors that are based on the color of the user's phone. It was announced at Samsung Developer Conference in 2018, and was unveiled in Galaxy Unpacked in February 2019 alongside the Galaxy S10 series, Galaxy Buds and the Galaxy Fold.
HarmonyOS (HMOS) is a distributed operating system developed by Huawei for smartphones, tablets, smart TVs, smart watches, personal computers and other smart devices. It has a multikernel design with dual frameworks: the operating system selects suitable kernels from the abstraction layer in the case of devices that use diverse resources. The operating system was officially launched by Huawei in August 2019.
The preferred license for the Android Open Source Project is the Apache Software License, 2.0. ... Why Apache Software License? ... For userspace (that is, non-kernel) software, we do in fact prefer ASL2.0 (and similar licenses like BSD, MIT, etc.) over other licenses such as LGPL. Android is about freedom and choice. The purpose of Android is promote openness in the mobile world, but we don't believe it's possible to predict or dictate all the uses to which people will want to put our software. So, while we encourage everyone to make devices that are open and modifiable, we don't believe it is our place to force them to do so. Using LGPL libraries would often force them to do so.
