Android is a mobile operating system developed by Google, based on the Linux kernel and designed primarily for touchscreen mobile devices such as smartphones and tablets. Androids user interface is mainly based on direct manipulation, using touch gestures that loosely correspond to real world actions, such as swiping, tapping and pinching, to manipulate on screen objects, along with a virtual keyboard for text input. In addition to touchscreen devices, Google has further developed Android TV for televisions, Android Auto for cars, and Android Wear for wrist watches, each with a specialized user interface. Variants of Android are also used on game consoles, digital cameras, PCs and other electronics. Initially developed by Android Inc., which Google bought in 2. Android was unveiled in 2. Open Handset Alliance  a consortium of hardware, software, and telecommunication companies devoted to advancing open standards for mobile devices. Beginning with the first commercial Android device in September 2. Oreo, released in August 2. Android applications apps can be downloaded from the Google Play store, which features over 2. February 2. 01. 7. Android has been the best selling OS on tablets since 2. As of May 2. 01. 7update, Android has two billion monthly active users, and it has the largest installed base of any operating system. Androids source code is released by Google under an open source license, although most Android devices ultimately ship with a combination of free and open source and proprietary software, including proprietary software required for accessing Google services. Android is popular with technology companies that require a ready made, low cost and customizable operating system for high tech devices. Its open nature has encouraged a large community of developers and enthusiasts to use the open source code as a foundation for community driven projects, which deliver updates to older devices, add new features for advanced users or bring Android to devices originally shipped with other operating systems. The extensive variation of hardware in Android devices causes significant delays for software upgrades, with new versions of the operating system and security patches typically taking months before reaching consumers, or sometimes not at all. The success of Android has made it a target for patent and copyright litigation between technology companies. History. Former Android logo wordmark 2. The Sooner prototype phone,1. Android. Android Inc. Palo Alto, California in October 2. Andy Rubin, Rich Miner, Nick Sears, and Chris White. Rubin described the Android project as tremendous potential in developing smarter mobile devices that are more aware of its owners location and preferences. The early intentions of the company were to develop an advanced operating system for digital cameras, and this was the basis of its pitch to investors in April 2. The company then decided that the market for cameras was not large enough for its goals, and by five months later it had diverted its efforts and was pitching Android as a handset operating system that would rival Symbian and Microsoft Windows Mobile. Rubin had difficulty attracting investors early on, and Android was facing eviction from its office space. Steve Perlman, a close friend of Rubin, brought him 1. Perlman refused a stake in the company, and has stated I did it because I believed in the thing, and I wanted to help Andy. In July 2. 00. 5,1. Google acquired Android Inc. Its key employees, including Rubin, Miner and White, joined Google as part of the acquisition. Not much was known about the secretive Android at the time, with the company having provided few details other than that it was making software for mobile phones. At Google, the team led by Rubin developed a mobile device platform powered by the Linux kernel. Google marketed the platform to handset makers and carriers on the promise of providing a flexible, upgradeable system. Google had lined up a series of hardware components and software partners and signaled to carriers that it was open to various degrees of cooperation. Speculation about Googles intention to enter the mobile communications market continued to build through December 2. An early prototype had a close resemblance to a Black. Berry phone, with no touchscreen and a physical QWERTYkeyboard, but the arrival of 2. Applei. Phone meant that Android had to go back to the drawing board. Google later changed its Android specification documents to state that Touchscreens will be supported, although the Product was designed with the presence of discrete physical buttons as an assumption, therefore a touchscreen cannot completely replace physical buttons. In September 2. 00. Information. Week covered an Evalueserve study reporting that Google had filed several patent applications in the area of mobile telephony. On November 5, 2. Open Handset Alliance, a consortium of technology companies including Google, device manufacturers such as HTC, Motorola and Samsung, wireless carriers such as Sprint and T Mobile, and chipset makers such as Qualcomm and Texas Instruments, unveiled itself, with a goal to develop the first truly open and comprehensive platform for mobile devices. The first commercially available smartphone running Android was the HTC Dream, also known as T Mobile G1, announced on September 2. Since 2. 00. 8, Android has seen numerous updates which have incrementally improved the operating system, adding new features and fixing bugs in previous releases. Each major release is named in alphabetical order after a dessert or sugary treat, with the first few Android versions being called Cupcake, Donut, Eclair, and Froyo, respectively. During its announcement of Android Kit. Kat in 2. 01. 3, Google explained that Since these devices make our lives so sweet, each Android version is named after a dessert, although a Google spokesperson told CNN in an interview that Its kind of like an internal team thing, and we prefer to be a little bit how should I say a bit inscrutable in the matter, Ill say. In 2. 01. 0, Google launched its Nexus series of devices, a lineup in which Google partnered with different device manufacturers to produce new devices and introduce new Android versions. The series was described as having played a pivotal role in Androids history by introducing new software iterations and hardware standards across the board, and became known for its bloat free software with timely. Two serial ports RS2. RS4. 22 conflicting with each other. USB1 crash Ubuntu. Xchanger. Last Updated November 2. AM 0 Votes. Problem My Ubuntu OS cannot handle two serial ports when the serial devices that are connected to the serial ports are powered on. Synopsis of symptoms When the two serial to USB converters are connected to the PC without any serial devices connected to them all is fine they show up as tty. USB0 and tty. USB1. However, as soon I connect serial devices to them, and power the serial devices on, one of the serial ports crashes it disappears from the dev directory. This is not a hardware issue or wiring issue. Something is going on in the OS that is adding gray hair to my head. Could you please assist Please read on for details. I am running Ubuntu 1. Lenovo laptop.

Please see https pastebin. CYXe. Ka. 9Tested conclusions I have come to over the past 5 days The serial devices connected to the RS2. RS4. 22 work exactly as the manufacturer describes in the manuals when only one of the devices is plugged in at a time. The serial devices are not malfunctioning or broken in any way. If only one device is plugged in at a time, I can communicate with it and control it, and it behaves correctly. The wiring to all the devices is good double and triple checked using drawings and meterI have removed the USB hub I was using, and it took a long time to figure out that it was not the hubs fault. I have ruled out the various software packages I am using to read the serial data I feel that the steps outlined in this posting prove this. It is interesting to comment that this issue occurs without me even sending or receiving commands to the serial devices When I power up the device connected to the RS2. USB converter, the serial device is not yet sending messages or at least I dont believe that it is, but the serial port is immediately dropped by the operating system. Can you please let me know if this is fixable I have spent thousands of dollars buying hardware Sick LMS 2. Applied Motion Products SV7 servo drive and Servo motor and was not expecting this issue. Can you please suggest how to fix this issue As well, if I can provide any information or run any commands, please do not hesitate to let me know Thanks in advance.
