In the prologue of that first guide, we said: "The most important issues for mobile developers are for sure fragmentation and distribution". Although the mobile ecosystem’s landscape has seen massive changes since then, we still think this holds true. And it keeps changing: This 12th edition probably introduces more changes than any other release before. To reflect recent shifts in the market, we decided to remove the dedicated chapters about Qt and bada and replace them with new, platform-independent chapters which cover key technologies such as Augmented Reality, Ana- lytics and Prototyping. Additionally, the general introduction chapter has been significantly expanded and now provides a comprehensive, updated overview on the ever changing mobile world. All other chapters have, of course, also been revised and updated. You will hardly find a more objective and up-to-date guide that teaches you how to get started as an app provider or developer, and how to lift your existing mobile offering to the next level. What happened in the mobile industry since our last release? Apple released iPhone 5 with great success, Android became the clear global leader in smartphone systems, and Microsoft released both Windows 8 and Windows Phone 8. Mark Zuck- erberg criticized Facebook's own HTML5 approach and found massive usage growth after turning to native apps. Then there was Canonical presenting Ubuntu for mobile phones. Finally, BlackBerry surprised us developers with love songs and released the BlackBerry 10 OS. Prologue I We will establish a bi-annual release cycle from now on. So expect the 13th edition around October 2013.

This is an open community project and we invite all of you to push it even further forward. We are looking forward to hearing from you! Robert + Marco / Enough Software Bremen, February 2013 Prologue II The Galaxy of Mobile: An Introduction Welcome to the world of mobile development, a world where former giants stumble and new stars are born on a seemingly regular basis. The focus of this book is on developing mobile apps, which includes a number of phases including: planning & specifica- tion, prototyping & design, implementation, internal testing & deployment, deployment to an app store, discovery by users, installation, use and feedback. Ultimately, we want our users Robert Virkus & Marco Tabor & Matos Kapetanakis & Matos Tabor Robert Virkus & Marco to enjoy using our apps and to give us positive ratings to BY encourage other users to do likewise. Keep reading to learn how to develop apps for the major platforms. Should this be the first time that you have con- sidered getting involved, we advise against further delay as the world is moving speedily towards mobile becoming the predominant form of computing and others will surely bypass you if you wait too long. While developing mobile apps has some commonalities with developing other software it has specific characteristics. We will cover some of these next. Topology: Form Factors and Usage Patterns You have to differentiate between smart phones, tablets and feature phones. Each form factor poses its own usability chal- lenges; for instance, a tablet demands different navigation than a phone. TV systems are getting more traction as another form factor for mobile developers. The Galaxy of Mobile: An Introduction 1 Android usage patterns, of course, differ from those on iOS, which also differ from those for Windows Phone apps, et cetera. You should, therefore, refrain from providing the identi- cal experience on all form factors or even all your target smartphone systems. Otherwise, you risk delivering a mediocre service to some sections of your target user base. Star Formation: Creating a Mobile Service There are several ways to realize a mobile service: — App — Website — SMS, USSD1 and STK2 App Apps run directly on the device. You can realize them as native, web-based or hybrid apps. Native Apps A native app is programmed in a platform specific language with platform specific APIs. It is typically purchased, down- loaded and upgraded through the platform specific central app store. Native apps usually offer the best performance, the deep- est integration and the best overall user experience compared to other options. However, native development is often also the most complex development option. 1 en.wikipedia.org/wiki/USSD 2 en.wikipedia.org/wiki/SIM_Application_Toolkit The Galaxy of Mobile: An Introduction 2 Web Apps A web app is based on HTML5, JavaScript and CSS and does not rely on any app store. It is a locally stored mobile site that tries to emulate the look-and-feel of an app. A famous example for a web app is the Financial Times app which left the app store in order to keep all subscriber revenue to themselves for the web world; inversely, the web-based Facebook iOS app was revamped into native app in order to dramatically improve its performance and usability. There are several web app frameworks available to build a native wrapper around it so that you can publish them in app stores, e.g. Phonegap3. Hybrid Apps A hyped controversy circles around whether native or web apps are the future. For many mobile app developers, this controversy does not really exist any longer as a hybrid approach to app development has become quite common place: An app can use native code for enhanced performance and integration of the app with the platform while using a webview together with HTML5-based content for other parts of the same app. A hybrid app makes 3 www.phonegap.com 3 use of native and web technologies. Parts of it behave as a native app, while other parts are powered by web technologies. These parts can use Internet connectivity to offer up-to-date content. While this could be viewed as a drawback, the use of web technologies enables developers to display up-to-date content without the need to re-submit the application to app stores.

  • June 7, 2010 ANALYSIS of the FTC's DECISION NOT to BLOCK
    June 7, 2010 ANALYSIS OF THE FTC’S DECISION NOT TO BLOCK GOOGLE’S ACQUISITION OF ADMOB Randy Stutz and Richard Brunell* Introduction On May 21, 2010, after months of investigation, the Federal Trade Commission (FTC) announced that it would not challenge Google’s $750 million acquisition of AdMob, a mobile advertising network and mobile ad solutions and services provider.1 In this white paper, we present AAI’s analysis of the FTC’s decision. The FTC found that, but for recent developments concerning Apple, the acquisition “appeared likely to lead to a substantial lessening of competition in violation of Section 7 of the Clayton Act.” According to the FTC, Google and AdMob “currently are the two leading mobile advertising networks, and the Commission was concerned about the loss of head-to-head competition between them.” The companies “generate the most revenue among mobile advertising networks, and both companies are particularly strong in … performance ad networks,” i.e. those networks that sell advertising by auction on a “per click” or other direct response basis. Without necessarily defining a relevant market, the Commission apparently saw a likelihood of unilateral anticompetitive effects, as it found “each of the merging parties viewed the other as its primary competitor, and that each firm made business decisions in direct response to this perceived competitive threat.” Yet, Apple’s acquisition of the third largest mobile ad network, Quattro Wireless, in December 2009, and its introduction of its own mobile advertising network, iAd, as part of its iPhone applications package, convinced the FTC that the anticompetitive effects of the acquisition “should [be] mitigate[d].” The Commission “ha[d] reason to believe that Apple * Randy Stutz is a Research Fellow and Richard Brunell is the Director of Legal Advocacy of the American Antitrust Institute (AAI), a non-profit research and advocacy organization devoted to advancing the role of competition in the economy, protecting consumers, and sustaining the vitality of the antitrust laws.

  • July 23, 2020 the Honorable William P. Barr Attorney General United
    July 23, 2020 The Honorable William P. Barr Attorney General United States Department of Justice 950 Pennsylvania Avenue, NW Washington, DC 20530 Dear Attorney General Barr: We write to raise serious concerns regarding Google LLC’s (Google) proposed acquisition of Fitbit, Inc. (Fitbit).1 We are aware that the Antitrust Division of the Department of Justice is investigating this transaction and has issued a Second Request to gather additional information about the acquisition’s potential effects on competition.2 Amid reports that Google is offering modest, short-term concessions to overseas enforcers to avoid a full-scale investigation of the transaction in Europe,3 we write to urge the Division to continue with its efforts to conduct a thorough and comprehensive review of this proposed merger and to take any and all enforcement action warranted by the law and the evidence. It is no exaggeration to say that Google is under intense antitrust scrutiny across the globe. As you know, the company has been under investigation for potential anticompetitive conduct across a number of product markets by the Department and numerous state attorneys general, as well as by a number of foreign competition enforcers, some of which are also reviewing the proposed Fitbit acquisition. Competition concerns about Google are widespread and bipartisan. Against this backdrop, in November 2019, Google announced its proposed acquisition of Fitbit for $2.1 billion, a staggering 71 percent premium over Fitbit’s pre-announcement stock price.4 Fitbit—which makes wearable technology devices, such as smartwatches and fitness trackers— has more than 28 million active users submitting sensitive location and health data to the company.

  • Comparison of GUI Testing Tools for Android Applications
    Comparison of GUI testing tools for Android applications University of Oulu Department of Information Processing Science Master’s Thesis Tomi Lämsä Date 22.5.2017 2 Abstract Test automation is an intriguing area of software engineering, especially in Android development. This is since Android applications must be able to run in many different permutations of operating system versions and hardware choices. Comparison of different tools for automated UI testing of Android applications is done in this thesis. In a literature review several different tools available and their popularity is researched and the structure of the most popular tools is looked at. The two tools identified to be the most popular are Appium and Espresso. In an empirical study the two tools along with Robotium, UiAutomator and Tau are compared against each other in test execution speed, maintainability of the test code, reliability of the test tools and in general issues. An empirical study was carried out by selecting three Android applications for which an identical suite of tests was developed with each tool. The test suites were then run and the execution speed and reliability was analysed based on these results. The test code written is also analysed for maintainability by calculating the lines of code and the number of method calls needed to handle asynchrony related to UI updates. The issues faced by the test developer with the different tools are also analysed. This thesis aims to help industry users of these kinds of applications in two ways. First, it could be used as a source on what tools are over all available for UI testing of Android applications.

  • If Google Is a 'Bad' Monopoly, What Should Be Done?
    If Google Is A 'Bad' Monopoly, What Should Be Done? Google Inc. is currently subject to antitrust investigations by state attorneys general in the United States, as well as antitrust authorities in the European Union. Google and its allies have mounted a vigorous public defense, arguing that Google’s activity should be immune from antitrust scrutiny or that imposing a remedy on Google would transform antitrust enforcers into some kind of undesirable “software regulatory agency,” which would threaten innovation in the Internet. These arguments are reminiscent of the claims made 20 years ago that antitrust analysis was too outdated to apply to high-tech industries. That argument was rejected then, and it should be rejected now. Exclusionary conduct by a dominant firm can distort fair competition in high-tech markets, Samuel Miller just as in more traditional markets. Antitrust remedies can, and should, be imposed to make sure that a dominant company does not improperly keep rivals out of its markets or improperly strengthen its dominant position, to the detriment of consumers and innovation. EU Competition Commissioner Joaquin Almunia rejected Google’s original proposals to resolve claims of anti-competitive conduct in July 2013, and is currently considering a revised proposal submitted by Google. So what remedy proposals would make sense? This article will outline potential antitrust remedies that may appropriately be imposed upon Google, assuming antitrust authorities or courts determine that Google has violated the antitrust laws. What Is an Illegal Monopoly? A company violates Section 2 of the Sherman Act when it acquires or maintains or “monopoly power” in a relevant market by “exclusionary” conduct.

As the region becomes more digitally connected, demand for Digital Services and technologies is also becoming more prominent. With the digital economy still in its infancy, it is unclear which global advances in Digital Services and technologies will be adopted by the Middle East and which require local development. In this context, identifying how, where and with whom to work with in this market can be very challenging. In our effort to broaden the discussion, we have prepared this report to define the Digital Services landscape for the Middle East, to help the region’s digital community in understanding and navigating through this complex and ever-changing space. Eng. Ayman Al Bannaw Today, we are witnessing an unprecedented change in the technology, media, and Chairman & CEO telecommunications industries. These changes, driven mainly by consumers, are taking Noortel place at a pace that is causing confusion, disruption and forcing convergence. This has created massive opportunities for Digital Services in the region, which has in turn led to certain industry players entering the space in an incoherent manner, for fear of losing their market share or missing the opportunities at hand.
