Transcript

  • 1. Android and Android Phones.Selom, Rick Rafael V.BM 12103
  • 2. Android (Operating System) Android is a Linux- based operating system for mobile devices such as smart phones and tablet computers, develop ed by Google in conjunction with the Open Handset Alliance.
  • 3. DEVELOPMENT  Android was initially developed by Android Inc, whom Google financially backed and later purchased in 2005. The unveiling of the Android distribution in 2007 was announced with the founding of the Open Handset Alliance, a consortium of 86 hardware, software, and te lecommunication companies devoted to advancing open standards for mobile devices. Google releases the Android code as open- source, under the Apache License.
  • 4. FOUNDATION Android, Inc. was founded in Palo Alto, California, Unit ed States in October 2003 by Andy Rubin, Rich Miner, Nick Sears and Chris White.
  • 5. Google acquisition  Google acquired Android Inc. on August 17, 2005, making Android Inc. a wholly owned subsidiary of Google. Key employees of Android Inc., including Andy Rubin, Rich Miner and Chris White, stayed at the company after the acquisition. Not much was known about Android Inc. at the time of the acquisition, but many assumed that Google was planning to enter the mobile phone market with this move.
  • 6. Open Handset Alliance On November 5, 2007, the Open Handset Alliance, a consortium of several companies which include Broadcom Corporation, Google, HTC, Intel, LG, Marvell Technology Group, Motorola, Nvidia,Qualco mm, Samsung Electronics, Sprint Nextel, T-Mobile and Texas Instruments unveiled itself. The goal of the Open Handset Alliance is to develop open standards for mobile devices. On the same day, the Open Handset Alliance also unveiled its first product, Android, a mobile device platform built on the Linux kernel version 2.6.
  • 7. Android Open Source Project  The Android Open Source Project (AOSP) is led by Google, and is tasked with the maintenance and development of Android. According to the project "The goal of the Android Open Source Project is to create a successful real-world product that improves the mobile experience for end users."AOSP also maintains the Android Compatibility Program, defining an "Android compatible" device "as one that can run any application written by third- party developers using the Android SDK and NDK", to prevent incompatible Android implementations. The compatibility program is also optional and free of charge, with the Compatibility Test Suite also free and open-source.
  • 8. Linux Androids kernel is based on the Linux kernel and has further architecture changes by Google outside the typical Linux kernel development cycle. Android does not have a native X Window System by default nor does it support the full set of standard GNU libraries, an d this makes it difficult to port existing Linux applications or libraries to Android.
  • 9. Applications  Applications are usually developed in the Java language using the Android Software Development Kit, but other development tools are available, including a Native Development Kit for applications or extensions in C or C++, Google App Inventor, a visual environment for novice programmers and various cross platform mobile web applications frameworks.
  • 10. Security Android applications run in a sandbox, an isolated area of the operating system that does not have access to the rest of the systems resources, unless access permissions are granted by the user when the application is installed. Before installing an application, the Play Store displays all required permissions. A game may need to enable vibration, for example, but should not need to read messages or access the phonebook. After reviewing these permissions, the user can decide whether to install the application.[The sandboxing and permissions system weakens the impact of vulnerabilities and bugs in applications, but developer confusion and limited documentation has resulted in applications routinely requesting unnecessary permissions, reducing its effectiveness.
  • 11. Privacy  Android smart phones have the ability to report the location of Wi- Fi access points, encountered as phone users move around, to build databases containing the physical locations of hundreds of millions of such access points. These databases form electronic maps to locate smart phones, allowing them to run apps like Foursquare, Latitude, Plac es, and to deliver location- based ads.
  • 12. Android, the worlds mostpopular mobile platform Android powers hundreds of millions of mobile devices in more than 190 countries around the world. Its the largest installed base of any mobile platform and growing fast—every day another million users power up their Android devices for the first time and start looking for apps, games, and other digital content.
  • 13. Powerful developmentframework  Android gives you everything you need to build best-in-class app experiences. It gives you a single application model that lets you deploy your apps broadly to hundreds of millions of users across a wide range of devices—from phones to tablets and beyond.
  • 14. Open marketplace fordistributing your apps Google Play is the premier marketplace for selling and distributing Android apps. When you publish an app on Google Play, you reach the huge installed base of Android. As an open marketplace, Google Play puts you in control of how you sell your products. You can publish whenever you want, as often as you want, and to the customers you want. You can distribute broadly to all markets and devices or focus on specific segments, devices, or ranges of hardware capabilities.
  • 15. Best Android phones
  • 16. Samsung Galaxy S3 (T-Mobile, AT&T, Sprint, Verizon, U.S. Cellular)  Pumped with high- performing hardware and creative software features, the Samsung Galaxy S3 is an excellent, top- end phone thats neck and neck with the HTC One X.
  • 17. HTC One X - (AT&T) Quad-core processing isnt everything, and AT&Ts new $199.99 HTC One X proves it. This advanced Android has style, speed, blazing 4G, and power galore.
  • 18. HTC One S - (T-Mobile)  The HTC One S is the best phone you can get on T-Mobile (for now), wrapping Android 4.0, 4G data speeds, and a beautiful 4.3-inch AMOLED screen into one svelte package.
  • 19. Motorola Droid Razr Maxx(Verizon Wireless) The Motorola Droid Razr Maxx proves that a powerful Android superphone can remain thin yet still promise marathon-worthy battery life.
  • 20. LG Nitro HD (AT&T)  With its gorgeous display, high-def everything, and 4G speeds, the LG Nitro HD has what it takes to compete; however, a few flaws keep it from trampling the competition.
