12. CATEGORIZATION OF MOBILE APP
DEVELOPMENT

13. Categorization of Mobile App
Development
• Web–based and related Frameworks
• Native platforms
• Hybrid WebKit/Native
• Proprietary middleware and clients

15. Technologies used for
Web based App Development
• Javascript libraries
– jQTouch
– Sencha Touch
– jQuery Mobile
• Web2.0
– AJAX
– JSON

16. Technologies used for Web based App
Development(Contd..)
• HTML 5
– Multimedia
– Geo-Location
– Offline storage
– MVC Client & Data Server
– Native APIs access

17. Technologies used for Native App
Development
• Android
• IOS
• Symbian
• BADA
• BLACK Berry
• Windows mobile
• Etc……

18. Native Mobile APP Dev (Contd..)
SDK Technologies based on SDK
Android Applications are written using the Java programming
language and run on Dalvik, a custom virtual machine
designed for embedded use which runs on top of a Linux
kernel.
IOS Applications are written using C, C++ and Objective-C
languages and run on XNU kernel on top of a X OS and Unix.
BADA Applications are written using C, C++ and Java
languages and run on Linux kernel. The source model is open
source and proprietary
Symbian Applications are written using C, C++ and Java
languages and run on Microkernel kernel. The source model
is proprietary
Windows Applications are written using VisualC++ and run on
Windows (Compact Edition) mobile OS

19. Technologies used for Hybrid App
Development
• Phone gap
• Appcelerator (formally titanium )
• APPi Mobi
• Rhodes
• TapLynx

24. PROS AND CONS OF MOBILE APP
DEV METHODOLOGIES

25. Pros and Cons -Web based Framework
Built with web based frameworks etc.
+ Single codebase
+ Easy to Learn
+ Best for frequently updated content
+ No Approvals needed
+No need to install/upgrade
- Web apps being slower than native apps
- Can’t be found on App store
- Don’t have access to all the methods exposed by the device OS

26. Pros and Cons - Native Apps
Built with Objective-C for iOS, Java for Android,
Visual C++ for Windows etc..
+ Best in class Performance
+ Great for graphics
+ Will work offline
+ Native Look and Feel
+ Leverage the full platform API
- New languages / API to learn
- Larger Teams / Longer Shipping time
- Multiple codebases to maintain
- Need to install
- Approval process needed
26

27. Pros and Cons - Hybrid Apps
Built with a framework that Works on most
popular devices with a single codebase
+ Quick Development
+ Can use some device hardware capabilities (depends on
framework)
+ Decent performance (depends on framework)
+ Customizable Look and Feel
- Doesn't perform as well as Native apps
- Good for form based / simple UI apps mostly
- Dependency on frameworks and their stability

28. DEMO

30. Android Demo
• Install Android SDK
• Install ADT Eclipse plugin
• Create an Android Virtual Device (AVD)
• Create Android Project with Eclipse (Wizard)
• Code it…
• Start it in Android Virtual Device (AVD)
