It controls all basic operations of the device and support higher level applications. A mobile operating system, or mobile OS, is an operating system that is specifically designed to run on mobile devices. A mobile OS runs on limited resources (computing power and storage) emphasizing communication. Note: OS was once tightly coupled with the hardware devices; but they had become a separate layer as devices became smart. While some computers such as typical laptops are 'mobile', the operating systems usually used on them are not considered mobile ones, as they were originally designed for desktop computers that historically did not have or need specific mobile features. Some mobile devices can run desktop OS. This distinction is becoming blurred in some newer operating systems that are hybrids made for both uses. 20 Mobile OS Market Share Multiple sources show Android and iOS are the dominant mobile OS currently Android is consistently above 80% world wide In US iOS is slightly more than Android m/os-market- share/mobile/united- states-of- america#monthly- 201707-201807 21 For more data sources: share-android-ios-windows-blackberry-2016-8 Applications and Services Applications, or mobile apps, are user facing functional software used on mobile devices Services are delivered through apps Growing types of applications that are integrated into the device Functional apps: financial, payment, socialization Device integrated apps: GPS Gaming Communication 22 App Store An app store (or app marketplace) is a type of digital distribution platform for computer software, often in a mobile context. Much like the online store, but the products are the apps Major ones Google Play Apple App Store Other notables Amazon Appstore _distribution_platforms 23 App Development Platform Platform A platform defines and supports all major app features and activities Usually includes hardware and operating systems Sometimes also includes application development and management frameworks Major mobile platforms: Android, Apple (iOS), Windows (mainly laptops) Development tools and frameworks. These include: Programming language SDK (run time, compilers, etc.) Code editor or IDE App frameworks Libraries and services App distribution/update methods App store: including official app store and third party app store Direct internet access or download 24 App Development Choices Platform native app These apps can only run on its target platform. The development tools and frameworks for each platform is different and no compatible. Major development platforms: Android, Apple iOS, Windows Cross platform Cross platform apps can run on multiple platforms using one set of development tools and frameworks. Further categorized as Cross platform native app Hybrid web app Web app (app like website) or mobile friendly website 25 Mobile App Development Options 26,_HTML5,_or_Hybrid: _Understanding_Your_Mobile_Application_Development_Options A program designed to run directly on a specific mobile operating system. A web based application that runs in any web browser especially that designed for mobile devices. Applications developed using Web development technologies and wrapped in a mobile app container * New to the diagram: cross- platform native app (Xamarin) * New to the diagram: app like web site,_HTML5,_or_Hybrid:_Understanding_Your_Mobile_Application_Development_Options Comparison of the Three Development Options Native Apps Mobile Web Hybrid Device features Can fully utilize platform/OS features if allowed, such as camera, location, sensors, and interactions with file systems and other apps. Access to devices features are limited to the browser environment. Can utilize platform/OS features if provided by the SDK, which are usually provided as JavaScript APIs. UX/UI Best; smooth interaction as UI is very responsive. Not as good as native app; may have delays. Looks like an app, but may have performance issues. Development Platform Applications are platform dependent. They have to be written and/or compiled to a specific OS*. Example: - Andriod (Java) ( Android ) - iOS (Objective C, Swift) - Windows (.Net, C#) - * Xamarin (all) Web applications are cross platform and can use standard languages such as HTML/CSS/JavaScript. Programs runs in browsers, although they may have slightly differences in different browsers. Hybrid applications are developed using standard web technologies, but complied to each specific platform. Distribution / Installation App Store, or direct downloaded; need installation Web; no installation App Store, or direct downloaded; need installation Cross-Platform Native App This solution uses a common development environment for all platforms, but wraps (compiles) them to a target platform. Wrapping all native OS libraries Similar to hybrid, but the apps are native apps, not relying on browser engines. Example development framework Xamarin: Using C# and .Net for development React Native platform-mobile-frameworks-comparison/ Is Xamarin hybrid? The short answer is no. platform-should-you-choose Others 28 Application Framework The main aim of frameworks is to increase productivity by reducing efforts which eventually saves lot of time for developers to resolve any other important issues in the app or game. These frameworks provides inbuilt tools for developers to work instantly on difficult and lengthy part of coding. Vendor frameworks Android SDK Cocoa Touch Major third party frameworks Ionic jQuery mobile: Sencha Touch Titanium Appcelerator Framework7 More: 29 Services and Service Providers Mobile backend as a service (MBaaS), also known as "backend as a service" (BaaS) is a model for providing web app and mobile app developers with a way to link their applications to backend cloud storage and APIs exposed by back end applications while also providing features such as user management, push notifications, and integration with social networking services. Top providers Kinvey Sencha Parse Azure service-mobile/ 30 Mobile User Experience User experience a person's perceptions and responses that result from the use or anticipated use of a product, system or service encompasses all aspects of the end-user's interaction with the company, its services, and its products. Mobile user experience User experience toward mobile devices Use of mobile devices and wearables, and applications or services running on such devices. Key differences Portable Screen Screen size is generally smaller Screen resolution is lower and density is higher Fragmented market: properties vary a lot among devices Orientation: vertical screens accounts for 29% of usage Interaction method: touch is different form pointing device Connection and speed Mobile device connection is less stable, inconsistent, and slower Variable connectivity Device capability Mobile devices have much more functionality integrated: cam, mic, sensors, GPS, etc. Computing limited 31 Good Resources Community resources https://mobileecosystemfor m/pubs/ ml ournals/misy/ Influencers fling News m/topic/cellphones/ m/topic/tablets/ http://mobileecosystemfor 32 Data, Stats, and Reports Organizational reports Cisco Visual Networking Index provider/visual-networking-index-vni/index.html KPCB Internet Trends General stats Browser: Other Reports Android devices: 33 KSU Courses The BSIT "Mobile and Web" elective track This program is rated #3 in The 10 Best Online Mobile App Development Degrees mobile-computing-degrees-bachelors/ CSE 3203 Mobile System Overview IT 4213 Mobile Web Development 34
