1Understanding Android
1 Understanding Android In mobile device terms, the word Android can refer to either an Android device or to the Android operating system. In very simple terms, an Android device is any device that runs the Android operat- ing system. You might also encounter androids from science fiction films and books, which are robots that resemble people, but that’s not the type of Android I discuss in this book. You don’t need to understand what Android is or how it works to use it. You can simply turn your device on and start pressing buttons and tapping icons and you’ll probably get along just fine. That approach worked just fine for my 3-year-old daughter; she figured it out pretty quickly, much to my dismay. But in case you want a small peek behind the Android curtain, this chapter is for you . Introducing the Android Operating System Android is the operating system that powers all Android devices. Much like how the Windows operating system powers laptop and desktop computers, or Apple’s iOS (formerly known as the iPhone OS) powers iPhones and iPads. Think of it as the underlying software that instructs your device what to do. When you install an Android app onto an Android device, you are installing an app that was written spe- cifically for the Android operating system. You can’t install a Windows app on an Android device, and you can’t install an Android app onto a Windows computer. Actually, that last part isn’t exactly true. You actually can install Android apps onto a Windows computer — and even on Macs and Linux PCs, for that matter — but only if the computer is running a special piece of software called an Android emulator, which creates a virtual Android device on your computer. -
A Survey Onmobile Operating System and Mobile Networks
A SURVEY ONMOBILE OPERATING SYSTEM AND MOBILE NETWORKS Vignesh Kumar K1, Nagarajan R2 (1Departmen of Computer Science, PhD Research Scholar, Sri Ramakrishna College of Arts And Science, India) (2Department of Computer Science, Assistant Professor, Sri Ramakrishna College Of Arts And Science, India) ABSTRACT The use of smartphones is growing at an unprecedented rate and is projected to soon passlaptops as consumers’ mobile platform of choice. The proliferation of these devices hascreated new opportunities for mobile researchers; however, when faced with hundreds ofdevices across nearly a dozen development platforms, selecting the ideal platform is often met with unanswered questions. This paper considers desirable characteristics of mobileplatforms necessary for mobile networks research. Key words:smart phones,platforms, mobile networks,mobileplatforms. I.INTRODUCTION In a mobile network, position of MNs has been changing due todynamic nature. The dynamic movements of MNs are tracked regularlyby MM. To meet the QoS in mobile networks, the various issuesconsidered such as MM, handoff methods, call dropping, call blockingmethods, network throughput, routing overhead and PDR are discussed. In this paper I analyse the five most popular smartphone platforms: Android (Linux), BlackBerry, IPhone, Symbian, and Windows Mobile. Each has its own set of strengths and weaknesses; some platforms trade off security for openness, code portability for stability, and limit APIs for robustness. This analysis focuses on the APIs that platforms expose to applications; however in practice, smartphones are manufactured with different physical functionality. Therefore certain platform APIs may not be available on all smartphones. II.MOBILITY MANAGEMENT IP mobility management protocols proposed by Alnasouri et al (2007), Dell'Uomo and Scarrone (2002) and He and Cheng (2011) are compared in terms of handoff latency and packet loss during HM. -

1 Smartphones and Symbian OS
1 Smartphones and Symbian OS Symbian OS is a full-featured, open, mobile operating system that powers many of today’s smartphones. As these smartphones become more pow- erful and popular, the demand for smartphone software has grown. Symbian smartphones are shipped with a variety of useful pre-loaded and targeted applications, which are selected by each phone’s manu- facturer. Today, the average Symbian smartphone ships with over 30 pieces of third-party software pre-installed. However, the exciting aspect of Symbian smartphones is that they are ‘open’, meaning that users can further customize their phone experience by downloading, installing, and uninstalling applications written by third-party developers (or by the users themselves). Users can download applications from a PC to the smartphone through a link such as USB, or Bluetooth technology, or over-the-air via the Internet. With the largest installed base of smartphones worldwide, Symbian OS offers a great opportunity for software developers to establish them- selves in the mobile market by creating novel and exciting software for the growing mass of smartphone users around the world. There is a growing list of Symbian applications available as freeware or as paid downloads on numerous Internet sites (http://www.handango.com and http://www.epocware.com are good examples). They range from pro- ductivity, entertainment, navigation, multimedia, and communications software to programs that can count fast food calories, improve your golfCOPYRIGHTED swing, keep diaries, and calculate MATERIAL foreign currency exchange. And business opportunities aside, sometimes it’s just plain fun writing your own code to run on your own smartphone. -
Smartphones: Ask 4 Questions Before You Buy
Vol. 5, No. 4 / April 2006 Smartphones: Ask 4 questions before you buy PDA/cell phone combinations let you surf the Internet, plan your schedule, and more. Which models are right for your practice? Richard A. Montgomery, MD Private practice, Sage Health Care, Boise, ID ‘Smartphones,’ hybrid cell phones and personal digital assistants (PDAs), are increasingly helping psychiatrists stay in touch on the road or manage multi-site practices. This article reviews the capabilities of most smartphone models (Table) and offers practical advice to help you choose the right device for your practice. WHAT YOU CAN DO WITH A SMARTPHONE Make phone calls. Most smartphones integrate high-end wireless phone features such as selective call screening, Bluetooth wireless device compatibility, moderate-resolution cameras, and voice recognition for hands-free dialing. Call quality varies by device but is generally above average as cell phones go. Smartphones cost between $100 and $500 depending on model (the more cutting-edge the smartphone, the higher the price) and whether a service activation discount is offered. A service provider’s area and coverage uniformity usually affects call quality. Some service plans include data service (ie, e-mail) with phone service, whereas others charge an extra monthly fee depending on volume of data to be transmitted. Send and receive e-mail. Smartphones include fully featured e-mail clients. While away from the office, you can save immeasurable time communicating with staff and colleagues via text instead of paging and waiting for callbacks. “Pop-ups” let you quickly view and respond to e-mails without disrupting workflow. -
