Mobile and Smartphone ApplicationsMobile Phones

A mobile phone (also called mobile, cellular telephone, cell phone, or hand phone is an electronic device used to make

1. Calls across a wide geographic area. 2. Send Text SMS3. Can see call records4. Can capture image 5. Can run music 6. Can browse web etc.

You’ll get detailed history about how this technology evolved over the years

Mobile and Smartphone ApplicationsMobile Phone Applications: Development

1. Different Mobile phone vendor companies use different platforms for developing applications for their own platform.

2. We’ll discuss about a open “Legacy” platform as an example which is J2ME

Java Platform, Micro Edition, or Java ME: 1. It is a Java platform designed for embedded systems (mobile

Devices are one kind of such systems) . 2. Target devices range from industrial controls to mobile phones

with Java (KVM support). Formerly known as Java 2 Platform, Micro Edition (J2ME).For details:http://en.wikipedia.org/wiki/Java_Platform,_Micro_Edition

Nokia, Samsung, Sony Ericsson and many other vendors supports J2ME for applications and games development

Mobile and Smartphone ApplicationsMobile Phone Applications: Development With J2MELimitations1. Memory Issues

1. Vendor Specific Implementation2. Insufficient Memory3. Inefficient Memory Management

2. Device Compatibility Issues3. Not enough Access to Core System of the Phone4. Vendor Specific Implementation of KVM

That is why…We see sites like this:

Mobile and Smartphone ApplicationsSmart Phones1. A smartphone is a mobile phone that

offers more advanced computing ability, Features and connectivity than a contemporary mobile phones.

2. Smartphones may be thought of as handheld computers integrated with a mobile telephone.

3. They also provide their own Operating System with Application Development Framework

• Technical Advantages– Android is built upon an open-source platform, and most of the

Android code is released under the free software/open source Apache License.

– Rich and easy to integrate feature sets.– Android applications are written in the Java programming language,

which is a powerful, mature and very widely adopted language. – Easy to learn than Apple’s Objective-C– Inter-Application communication is easier.

• Business Advantages– Android Market — is much more of an open marketplace than Apple‘s

iTunes App Store. – No delay for approval of submitted application. So you can reach your

users fast.

Why Android Platform?

Why Android Platform? (Contd.)Fastest growing smartphone platform

Why Android Platform? (Contd.)Android Growth Explodes in 2010 according to Flurry AnalyticsBy Flurry’s count, devices running on Android OS now exceed 60 million. From 2009 to 2010, Android adoption increased by nearly 10 times, from 5.9 million to 53 million devices.

Why Android Platform? (Contd.)Business OpportunitiesAndroid market (https://market.android.com/)

Android Market is the online software store developed by Google for Android devices. An application program ("app") called "Market" is preinstalled on most Android devices and allows users to browse and download apps published by third-party developers, hosted on Android Market. As of December 2010 there were about 200,000 games, applications and widgets available on the Android Market, with an estimated 2.5 billion total downloads.

Android is a software stack for mobile devices that includes an

operating system, middleware and key applications. The Android SDK provides the tools and APIs necessary to begin developing applications on the Android platform using the Java programming language.

What is Android

Google describes Android as:The first truly open and comprehensive platform for mobile devices, all of the software to run a mobile phone but without the proprietary obstacles that have hindered mobile innovation.

But what’s so exciting about this???We have answered it

Android Features

Features1. Application framework2. Dalvik virtual machine 3. Integrated browser4. Optimized graphics 5. SQLite 6. Media support 7. GSM Telephony 8. Bluetooth, EDGE, 3G, and WiFi 9. Camera, GPS, compass, and accelerometer 10.Rich development environment

We’ll cover each of these features in our corresponding sessions

General Course Outline• Introduction to Android and Mobile Devices• Setting up Development Environment• Application Architecture and Lifecycle• Java Language Basics and Syntax• Object Oriented Programming in Java• Vertical and Horizontal Libraries in Java• Object Oriented Principles and Practice• Building Android Applications• Android User Interface• Common Controls• Android Application Components: Activity, BroadcastListener,

Service, Content Provider

General Course Outline• Data Storage and Relational Database: SQLite• Maps, Geocoding and Location Based Services• Communication with Internet• RESTful Web Services• Working with Multimedia• Basic Game Development Concepts• Performance Tuning• Some More about Object Oriented Programming• Debugging, Testing & Deploying Android Applications (with

Digital Signature)

1. We’ll need at least basic understanding of how to program in Java/C#. Android programming is done using Java syntax, plus a class library that resembles a subset of the Java SE library (plus Android-specific extensions).

2. We’ll need some basic OOP concept.
