2. Introduction to mobile device
• A mobile device is small packet sized handheld and extremely portable computing
device having display screen with touch input or miniature keyboard.

6. Model and Platform of Mobile device
• Mobile operating system also known as mobile platform or a handheld
operating system is the operating system that controls a mobile device or
information appliance.
• The most used mobile operating system are:
• Android
• iOS
• Windows phone
• BlackBerry
• Symbian
• Tizen
• Ubuntu touch
• FireFox os

7. Android
• Android is an open source Linux-derived platform backed by google
Inc. Along with major hardware and software developers
• It is largest installed base worldwide on smart phones
• Android application can be downloaded from google play store
• Currently android 11 is available.

8. iOS
• It is closed source platform built on open source Darwin core
operating system
• Earlier called iPhone OS is created and developed by Apple Inc.
• Distributed extremely for apple hardware such as iPhone, iPad, iPod
touch and second-generation apple TV.
• It is available in 34 different language worldwide.
• Hybrid type kernel based.

9. Windows Phone
• The third largest installed based on smartphones behind Android and iOS
• It is closed source and proprietary platform.
• It was developed by Microsoft for smartphones as replacement to successor
to windows phone.
• It was available in130 different languages.
• Hybrid type kernel based

10. • BlackBerry
• It is closed source and proprietary mobile operating system developed by Canadian
company BlackBerry limited for its BlackBerry lie of Smartphone handheld devices.
• It is originally designed for business.
• Its kernel use JVM
Symbian
• It is open source operating system and software platform designed for smartphones.
• The Symbian platform was created by merging and integrating software asset contributed
by Nokia, NTT, Sony Ericson and Symbian Ltd.
• It was available in multi-lingual

11. Tizen
• It is a new free and open source Linux- based operating system.
• It works on smartphones, tablet and smart television etc.
• Its kernel type is monolithic kernel.
Ubuntu Touch
• It is open source mobile version of ubuntu operating system being
developed by UBports community.
• It was designed primarily for touch screen mobile devices.

12. FireFox OS
• It is open source operating system designed by Mozilla and external
contributors.
• Made for smartphones, tablet, computer and smart TV.

13. Why Mobile programming
• 7 Billion+ mobile phone user in the world.
• A mobile phone (also called Smartphone, cellular telephone , cell phone and hand
phone) is an electronic device used to make
• Call across a wide geographic area.
• Send text sms
• Can see call records
• Can capture image
• Can run music
• Can browse web etc.
• Human interaction with mobile phone device is more than any other device.

14. Mobile Programming
• Mobile programming provides custom application development services.
• It has served its customer in different areas such as retail, entertainment, gaming,
healthcare, insurance, banking and have implementation across various platform
like windows phone, iPhone, Android, Symbian and BlackBerry etc.
• Mobile programming is a way to develop mobile application.
• Mobile application development is process of writing software for small portable
devices such as PDA, Smartphone, or tablet etc.
• Different mobile vendor companies use different platforms for developing
application for their own platform.

15. • Initially there are two way to build mobile to built mobile app- one for iOS
and one for Android.
• But today there is wide array of language, framework, SDKs and tools that
can be used to build App.
• Mobile app developers can build an app in one of the three categories.
• Native Application
• Progressive Web Application
• Hybrid Application

16. Native Application
• Native application coded in a language that is supported natively by specific device
operating system.
• Example: native iOS App and native Android App
Progressive web application
• Web applications, downloaded to a mobile web browser, differ from native ones in their
code.
• it is written using web technologies (HTML, JavaScript, and CSS) that are independent of
the operating system.
• It looks and feels like mobile app but not delivered natively on device

17. Hybrid Application
• Cross platform development
• Application are coded in one programming language that can run on multiple platforms.
• Hybrid applications, like web apps, are programmed using web technologies, but are
packaged as native ones.
• A hybrid app can be written for several mobile operating systems using a programming
language familiar to many developers.
• Hybrid programs can be distributed and installed through app stores, like native software.

18. Programming language for iOS Application
• The iOS platform was created by Apple Inc.
• If we develop an iOS app, it will work across Apple devices like iPhone,
iPads etc.
• Apps build by using iOS programming language can be made avilable on
the Apple App store for user to download.
• There are two native programming language for iOS app development
• Objective c
• Swift

19. Programming language for Android Application
• Android is an open source software development platform run by Google.
• To built an android app, we need to get the android development toolkit that has
debuggers, emulator and required SDKs
• Apps building by android programming language can be made available in Google
play store for user to download.
• The best integrated development environment for android app is a Android Studio.
• The two android programming languages are :
• Java
• Kotlin

20. Programming language for Hybrid App
• Hybrid application are developed once, but written with programming language that works for
multiple platforms.
• Most commonly, a single development will work for both iOS and Android.
• To built hybrid application , we are generally dealing with some sort of javaseript –based
language, framework or toolkit.
Xamarin and C#
• icrosoft eventually acquired the Xamarin framework, which allows app developers to program
using C# against other frameworks.
• Using an IDE for hybrid development, the C# code is cross-compiled to run natively on iOS and
Android devices.

21. JavaScript Languages
• he most popular hybrid languages use JavaScript frameworks.
• It’s kind of a general-purpose programming language for multiple use
cases.
• React Native
• Appcelerator
• Cordova/PhoneGap
• These are just a few of the top options. Google even has some niche
builders called Dart and Flutter.
