What is it?Let's lay (or re-lay) a foundation

What is a platform?A platform: hardware architecture and a software framework

Hardware:

Types of Applications(Platform-Wise)Native | Non-Native

NativeApplications

What are they ?

Native ApplicationsApplications coded in a specific programming language

Programming LanguageLanguage designed for programming computers

Programming LanguageThousands of themExamples, anyone ?

Programming LanguageThousands of them

Examples : PHP, C++, Java, VisualBasic, C#, Python, Perl, Fortran,QBasic

Native ApplicationsA native app is an application written purely in platform-specific

programming language

Non-Native

Non-Native!='Native Application'

i.e Not Platform Specific Programming

Non-Native AppBetter called "Cross Platform App"

Cross Platform Apps

One Code Base.Multiple Platforms

Well, mostly from one code base

Cross Platform AppsA cross platform app is an application written or compiled in a way

that allows it to run on multiple platforms.

With or Without Special Preparation

Cross Platform AppsTools & IDEs

* - HTML & Javascript based

Space for Examples

- Faster Deployment- Lower Dev & Maintenance Cost

- Easier Learning Curve- Easier Integration

Pros of CPD

- Non-Native Look- Limited Feature Support

IntroducingPlayer 3!{ Hybrid Apps }

This type of application has cross-platform compatibility but can stillaccess a phone's hardware.

Hybrid AppsThe best of both worlds

Hybrid AppsBuilt by combining a Cross Platform Language (e.g HTML5) and

the Platform-Specific Language (Android Java)

Hybrid AppsUse a regular IDE for HTML5 and Use the Platform SDK/IDE to

build the rest
