INTRODUCTION

Mobile phones are one of the most ubiquitous electronic devices. Mobile Devices are multi-

functional, portable, wireless connectivity, relatively limited resources and have longer power

back up. In India there are about 300 million phones available. Each phone will have many

features like calling, SMS, Bluetooth, internet, media players etc. Of all the modes of

communication SMS happens to be the most widely used because of cost and ease of

sending.SMS traffic in India is huge and considering an average user the SMS traffic will be

at least 50 messages.

1.1 Overview

There are many types of Mobile Devices and we can classify them based on the market

segment and device type. Mobile Devices based on Market Segments include devices for

Business use, Personal and consumer use, Multi-purpose. Mobile Devices based on Device

types include Smart phones, Table PC, Notebooks and single purpose devices such as mp3

players and navigation system.

1.2 Problem Statement

In todays Android Operating System based mobile phones has limited searching

functionalities in messaging inbox.

When search is made based on contact number/a persons name the search will results with

all the occurrences of input like mobile numbers or names in messages etc.. So in order to

over come the searching problems we are developing an efficient searching tool, which

searches the inbox based on Contact Name, Mobile Number etc..

1.3 Aim of the Project

MIST which stands for Mobile Inbox Search Tool is used to perform advanced searching

operations on the mobile inbox. This tool is being developed on ANDROID platform which

is an open source platform for mobile devices.

LITERATURE SURVEY

Various researchers all over the world are involved themselves in finding out various aspects

related to android. A selected bunch of references are discussed hereunder.

2.1 Android(operating system)

Android is an operating system (or, more precisely, a software stack) for mobile devices that

includes middleware and key applications, and uses a modified version of the Linux Kernel.

It was initially developed by Android Inc., a firm later purchased by Google, and lately by the

Open Handset Alliance. It allows developers to write managed code in the Java language,controlling the device via Google-developed Java libraries.

The unveiling of the Android distribution on November 5, 2007 was announced with

the founding of the Open Handset Alliance, a consortium of 80 hardware, software, and

telecom companies devoted to advancing open standards for mobile devices. Google released

most of the Android code under the Apache License, a free software and open source license.

On Feb 16, 2010 Google announced that 60,000 cell phones with Android are

shipping every day. According to a press estimate, the Android platform ranks as the fourth

most popular smart phone device-platform in the United States as of February 2010.

Google has also participated in the Android Market by offering several applications

for its services. These applications include Google Voice for the Google Voice service, Sky

Map for watching stars, Finance for their finance service, Maps Editor for their My Maps

service, Places Directory for their Local Search, Google Goggles that searches by image,

Google Translate, Listen for podcasts and My Tracks, a jogging application.

2.2 Survey of android

Google acquired Android, Inc., a small startup company based in Palo Alto, California,

USA. Android's co-founders who went to work at Google included Andy Rubin (co-founder

ofDanger), Rich Miner (co-founder of Wildfire Communications, Inc.), Nick Sears (once VP

at T-Mobile), and Chris White (headed design and interface development at WebTV). At the

time, little was known about the functions of Android, Inc. other than that they made software

for mobile phones. This began rumors that Google was planning to enter the mobile phone

market.

Figure 2.2 shows an Android at Googolplex

At Google, the team led by Rubin developed a mobile device platform powered by the

Linux kernel which they marketed to handset makers and carriers on the premise of providing

a flexible, upgradeable system. It was reported that Google had already lined up a series of

hardware component and software partners and signaled to carriers that it was open to various

degrees of cooperation on their part. More speculation that Google would be entering the

mobile-phone market came in December 2006. Reports from the BBC and The Wall Street

Journal noted that Google wanted its search and applications on mobile phones and it was

working hard to deliver that. Print and online media outlets soon reported rumors that Google

was developing a Google-branded handset. More speculation followed reporting that as

Google was defining technical specifications, it was showing prototypes to cell phone

manufacturers and network operators.

InformationWeek covered an Evalueserve study reporting that Google had filed

several patent applications in the area of mobile telephony.

Development

environment

Includes a device emulator, tools for debugging, memory and performance

profiling, and a plug-in for the Eclipse IDE.

Market Like many phone-based application stores, the Android Market is a catalog

of applications that can be downloaded and installed to target hardware

over-the-air, without the use of a PC. Originally only free applications

were supported. Paid-for applications have been available on the Android

Market in the United States since 19 February 2009. The Android Market

has been expanding rapidly. As of April 30, 2010, it had over 50,000

Android applications for download.

Multi-touch Android has native support for multi-touch which was initially made

available in handsets such as the HTC Hero. The feature was initially

disabled at the kernel level (possibly to avoid infringing Apple's patents on

touch-screen technology). Google has since released an update for the

Nexus One and the Motorola Droid which enables multi-touch natively.

Bluetooth Support for sending files over Bluetooth was added in version 2.0.

Video calling Android does not support video calling. However, it is possible if thephone runs an additional UI. This is proved on the HTC Eva 4G, which

runs Sense and can support video calling.

2.4 Hardware running Android

The first phone to run the Android operating system was the HTC Dream, released on 22

October 2008.By the end of 2009 there will be at least 18 phone models using Android

worldwide, according to Google. In addition to the mobile devices that ship with Android,

some users have been able (with some amount of hacking, and with limited functionality) to

install it on mobile devices shipped with other operating systems.

2.5 Software development

The early feedback on developing applications for the Android platform was mixed. Issues

cited include bugs, lack of documentation, inadequate QA infrastructure, and no public issue-

tracking system. (Google announced an issue tracker on 18 January 2008.) In December

2007, Merge Lab mobile startup founder Adam MacBeth stated, "Functionality is not there,

is poorly documented or just doesn't work... It's clearly not ready for prime time." Despite

this, Android-targeted applications began to appear the week after the platform was

announced. The first publicly available application was the Snake game. The Android Dev

Phone is a SIM-unlocked and hardware-unlocked device that is designed for advanced

developers.

Figure 2.4 shows the Early Android device

While developers can use regular consumer devices purchased at retail to test and use

their applications, some developers may choose not to use a retail device, preferring an

unlocked or no-contract device.

2.5.1 Software development kit

The Android SDK includes a comprehensive set of development tools. These include a

debugger, libraries, a handset emulator (based on QEMU), documentation, sample code, and

tutorials. Currently supported development platforms include x86-architecture computers

running Linux (any modern desktop Linux distribution), Mac OS X 10.4.8 or later, Windows

XP or Vista. Requirements also include Java Development Kit, Apache Ant, and Python 2.2

or later. The officially supported integrated development environment (IDE) is Eclipse (3.2 or

later) using the Android Development Tools (ADT) Plug-in, though developers may use any

text editor to edit Java and XML files then use command line tools to create, build and debug

A preview release of the Android software development kit (SDK) was released on 12

November 2007. On 15 July 2008, the Android Developer Challenge Team accidentally sent

an email to all entrants in the Android Developer Challenge announcing that a new release of

the SDK was available in a "private" download area. The email was intended for winners of

the first round of the Android Developer Challenge. The revelation that Google was

supplying new SDK releases to some developers and not others (and keeping this

arrangement private) has led to widely reported frustration within the Android developer

community.

Android Applications are packaged in .apkformat and stored under /data/app folder

on the Android OS. The user can run the command adb root to access this folder as only the

root has permissions to access this folder.

2.5.2 Android Developer Challenge

The Android Developer Challenge was a competition for the most innovative application for

Android. Google offered prizes totaling 10 million US dollars, distributed between ADC I

and ADC II. ADC I accepted submissions from 2 January to 14 April 2008. The 50 mostpromising entries, announced on 12 May 2008, each received a $25,000 award to fund further

development. It ended in early September with the announcement of ten teams that received

$275,000 each, and ten teams that received $100,000 each. ADC II was announced on 27

May 2009. The first round of the ADC II closed on 6 October 2009. The first-round winners

of ADC II comprising the top 200 applications were announced on 5 November 2009.

2.5.3 Google applications

Google has also participated in the Android Market by offering several applications for its

services. These applications include Google Voice for the Google Voice service, Sky Map for

watching stars, Finance for their finance service, Maps Editor for their MyMaps service,

Places Directory for their Local Search, Google Goggles that searches by image, Google

Translate, Listen for podcasts and My Tracks, a jogging application.

2.5.4 Third party applications

With the growing number of Android handsets, there has also been a growing interest by

third party developers to port their applications to the Android operating system.Famous

applications that have been converted to the Android operating system include Shazam,

Backgrounds, and Weather Bug.

The Android operating system has also been considered important enough by a lot of

the most popular internet sites and services to create native android applications. These

include MySpace and Face book.

The release of Mozilla Firefox browser for Android is planned for late 2010.

According to an interview with Mozilla's vice president of mobile, Jay Sullivan, conductedby TechRadar on February 17, 2010, part of the delay with the porting of Firefox over to

Android has been because Firefox Mobile is built on C and C++ code, but that the new

Native Development Kit makes it easier to port Firefox Mobile.

2.5.5 Native code

Libraries written in C and other languages can be compiled to ARM native code and installed

using the Android Native Development Kit. Native classes can be called from Java code

running under the Dalvik VM using the System.loadLibrary call, which is part of the standard

Android Java classes. Complete applications can be compiled and installed using traditional

development tools. The ADB debugger gives a root shell under the Android Emulator which

allows native ARM code to be uploaded and executed. ARM code can be compiled using

GCC on a standard PC. Running native code is complicated by the fact that Android uses a

non-standard C library (known as Bionic). The underlying graphics device is available as a

framebuffer at /dev/graphics/fb0. The graphics library that Android uses to arbitrate and

control access to this device is called the Skia Graphics Library (SGL), and it has been

released under an open source license. Skia has backends for both win32 and Cairo, allowing

the development of cross-platform applications, and it is the graphics engine underlying the

Google Chrome web browser.

2.5.6 Community-based firmware

There is a community of open-source enthusiasts that build and share Android-based

firmware with a number of customizations and additional features, such as FLAC lossless

audio support and the ability to store downloaded applications on the microSD card. This

usually involves rooting the device. Rooting lets users load modified firmwares allowing

users of older phones to use applications available only on newer releases.

Those firmware packages are updated frequently, incorporate elements of Android

functionality that haven't yet been officially released within a carrier-sanctioned firmware,

and tend to have fewer limitations. CyanogenMod is one such firmware.

On 24 September 2009, Google issued a cease and desist letter to the modder

Cyanogen, citing issues with the re-distribution of Google's closed-source applications within

the custom firmware. Even though Android OS is open source, phones come packaged with

closed-source Google applications for functionality such as the application store and GPS

navigation. Google has asserted that these applications can only be provided through

approved distribution channels by licensed distributors. Cyanogen has complied with

Google's wishes and is continuing to distribute this mod without the proprietary software. He

has provided a method to back up licensed Google applications during the mod's install

process and restore them when it is complete.

Research company Canalys estimated in Q2 2009 that Android had a 2.8% share of

worldwide smart phone shipments. By Q4 2010 this had grown to 33% of the market,

becoming the top-selling smart phone platform. This estimate includes the Tapas and OMS

variants of Android.

In February 2010 ComScore said the Android platform had 9.0% of the U.S.

smartphone market, as measured by current mobile subscribers. This figure was up from an

earlier estimate of 5.2% in November 2009. By the end of Q3 2010 Android's U.S. market

share had grown to 21.4 percent.

In May 2010, Android's first quarter U.S. sales surpassed that of the rival iPhone

platform. According to a report by the NPD group, Android achieved 25% smartphone sales

in the US market, up 8% from the December quarter. In the second quarter, Apple's iOS was

up by 11%, indicating that Android is taking market share mainly from RIM, and still has to

compete with heavy consumer demand for new competitor offerings. Furthermore, analysts

pointed to advantages that Android has as a multi-channel, multi-carrier OS, which allowed it

to duplicate the quick success of Microsoft's Windows Mobile.

In early October 2010, Google added 20 countries to its list of approved submitters.

By mid-October, purchasing apps will be available in a total of 32 countries. For a complete

list of countries that are allowed to sell apps and those able to buy them see Android Market.

As of December 2010 Google said over 300,000 Android phones were being activated

daily, up from 100,000 per day in May 2010.In February 2011, during the 2011 Mobile

World Congress, Eric Schmidt announced that Android has reached 350,000 activations per

day.At Google I/O, May 10, 2011, Google announced that 400,000 new Android devices are

activated every day and more than 100 million have been activate.

2.7 Restrictions and Issues

2.7.1 Kernel-related

Android uses a version ofLinux as its kernel (albeit tweaked by Google to fit Android

needs and separated from the main Linux kernel tree), but it is not a conventional Linux

distribution; it does not have a native X Window System, neither does it support the full

set of standard GNU libraries like its system libraries (GNU C Library). This makes it

difficult to reuse existing Linux applications or libraries on Android.
http://en.wikipedia.org/wiki/Linuxhttp://en.wikipedia.org/wiki/Linux_kernelhttp://en.wikipedia.org/wiki/X_Window_Systemhttp://en.wikipedia.org/wiki/GNUhttp://en.wikipedia.org/wiki/GNU_C_Libraryhttp://en.wikipedia.org/wiki/GNU_C_Libraryhttp://en.wikipedia.org/wiki/GNUhttp://en.wikipedia.org/wiki/X_Window_Systemhttp://en.wikipedia.org/wiki/Linux_kernelhttp://en.wikipedia.org/wiki/Linux


14/73



Google no longer maintains the Android code they previously contributed to the Linux

kernel, effectively branching kernel code in their own tree, separating their code from

Linux. The code which is no longer maintained was deleted in January 2010 from the

Linux codebase. However, Google announced in April 2010, that they will hire two

coders to work with kernel.org.

2.7.2 Issues concerning application development

Android does not use established Java standards, i.e. Java SE and ME. This prevents

compatibility among Java applications written for those platforms and those for the

Android platform. Android only reuses the Java language syntax, but does not provide the

full-class libraries and APIs bundled with Java SE or ME. However, Myriad's J2Android,launched on 19th March, 2010, allows seamless conversion of Java MIDlets into Android

applications.

Developers have reported that it is difficult to maintain applications working on different

versions of Android, because of various compatibility issues between versions 1.5 and

1.6, specifically concerning the different resolution ratios of the various Android phones.

Such problems were specifically encountered during the ADC2 contest.

Garbage collection will slow down programs that make too many memory allocations

allowing Dalvik to keep a pool of free memory. This may noticeably affect

responsiveness.

Android does not readily support Bluetooth file exchange, video call or native Java ME,

as do other mobile operating systems, such as Symbian OS and Windows Mobile,

however some of this is still possible: Bluetooth file exchange is possible on rooted

devices. Apps like Qik allow live broadcasting (but not receiving) and

KnockingLiveVideo for the iPhone is set to make an Android appearance. Third-party

XMPP clients such as BEEM could support the Jingle protocol soon. Java ME apps can

be converted with a MIDP runner that converts them to android apk's to be installed like

normal apps.

2.7.3 Issues for specific applications

Unlike other mobile closed platforms like Apple's phone OS, Google tracks issues and

feature requests at Google Code's site. The following outstanding issues have been highly

debated or voted for by the user community:

15/73



A source of criticism has been the lack of standards-based iCalendar/CalDAV

functionality in the Android calendar client. Currently, the Android calendar is restricted

to synchronization with Google Calendar service.

As of January 2010, the most requested ("starred") feature is the support for Bi-

directional text (right-to-left) such as Arabic, Persian and Hebrew.

Bluetooth voice dialing is also not supported. This feature in particular has caused some

surprise; many older phones have had this feature for several years.

Android does not support animated GIF files. It only shows the first frame.

Android does not support encrypted sending (SMTP+TLS) and receiving (IMAP+SSL) of

e-mail over self-signed certificates.

Because of potential security issues, Android does not officially allow applications to be

installed on, nor run from, an SD card. Current Android products such as the HTC Dream

and Magic have limited onboard memory and many users feel restricted by this lack of

functionality. However, several unsupported modifications exist to give the user this

capability.

Chapter 3

SOFTWARE REQUIREMENTS SPECIFICATION

A software requirements specification (SRS) is a comprehensive description of the intended

purpose and environment for software under development i.e., listing the functional and non-

functional requirements and language requirements for the project.

3.1 Functionality of the software

The functional Requirements are organized by features. Separate functionalities are provided

for each stated feature.

Search by Sender

In this feature the tool filters out messages from a particular sender. Once the user inputs few

characters, a search is performed to filter out the messages from the senders whose name

starts with these characters. Each time a character is entered or cleared, the existing character

string is taken as input, the search is performed and the results are displayed immediately. To

display the results no specific button such as search has to be pressed separately, meaning

as the user changes the input character string, the results displayed also change automatically

based on current input.

For example, if the user types letters Ab, the messages from senders whose name

starts with letters Ab such as Abhay, Abhi etc. gets filtered and are displayed.

Search by Number

In this feature searching is performed on the basis of senders number. The input to the search

application will be a integer. After the search is performed, the messages sent by that

particular number get displayed.

For example, if we search for 9449762999, then all the messages sent by

9449762999will get displayed.


17/73



Search by Date

This feature allows us to search and display messages which have arrived on a particular day

or until a particular time. When Search by date is chosen, the user is allowed to enter a date

and all the messages that have arrived on that day are displayed.

Unread Messages

This feature will display all the unread messages.

3.2 Software Requirements

The software requirements such as operating system, type of language and front end to usefor designing of graphical user interface are described here.

Eclipse 3.2 or higher versions

JDK 5 or JDK 6

Android Development Tools plug-in

Android SDK for windows is 2.2 Windows operating system.

SYSTEM ANALYSIS

After exploring existing mobile city guides and scenarios, I list the functionalities in different

priorities. The priorities are given according to the importance of functions for a city guide.

For example, the function of showing map is very important for a city guide. The priorities

are divided into three different levels: High (H), Medium (M), and Low (L). H is considered

the most important for a city guide and implemented firstly, M is less important and

implemented after H, L is the least important and considered to implement after the high and

medium. Normally, city guide should have basic functions: showing map and showing points

of interest (POIs) on map, providing some information about sights or events (e.g. when the

museum is open). In addition to them, we can add telephone function, the function of adding

review, the function of making tour plan, the function of event reminder and so on. As well, I

explore implementation of functionalities as many as possible based on the features of

powerful Android platform since investigating realization of a tailorable City Guide

application on the Android platform is the main purpose in the project.

Chapter 5

SYSTEM DESIGN

5.1 Development Methods

1. The development method that we are using for the development of our application is the

Evolutionary Development Model also known as Iterative Development Model.

2. This approach interleaves the activities of specification, development and validation. An

initial system is rapidly developed from the abstract specifications. This is then refined

with customer input to produce the system that satisfies the customers needs.

3. We chose this method to develop our application because this is a utility based

application .In this we have a initial set of requirements which is going to aid the user.

4. Once each of these utilities are developed it is going to be validated to see if it is fulfilling

the customer requirements and in case it is not it is modified to work as intended.

5.2 Architectural Strategies

This section contains any design decisions and/or strategies that affect the overall

organization of the system and its higher-level structures. These strategies provide insight

into the key abstractions and mechanisms used in the system architecture.

It also contains the reasoning employed for each decision and/or strategy (possibly

referring to previously stated design goals and principles) and how any design goals or

priorities were balanced or traded-off.

Few of the decisions are as follows

Use of a particular type of product

We are making use of Android Development framework because its open source, it provides

excellent development environment to develop the user interface and applications. It also

provides several native libraries like surface manager,SQLite,media framework etc.


23/73



Future plans for extending or enhancing the software

We are currently developing this as an independent application and hope to integrate it

into the default message inbox provided by android. We are developing this on Android

and in future hope to extend this to other platforms like Symbian (used by Nokia).

User interface paradigms

In Android user interfaces can be designed using one of the two methods Procedural and

Declarative.Procedural involves writing code in java to create and manipulate user interface

objects.Declarative design doesnt involve any code. This makes use of Markup language

based on XML. In our project we make use of both of the methods as and when required.

Hardware and/or software interface paradigms

Eclipse with ADT Plug-in and android SDK provides us with the emulators and interfaces

required for development.

Management of resources

Android uses Linux for its Memory management, networking, process management and

other operating system services.

External databases and/or data storage management and persistence

Android framework provides SQLite libraries for data storage management.

Communication mechanisms

Intents are system messages, running around the inside of the device, notifying applications

of various events, from hardware state changes (e.g., an SD card was inserted), to incoming

data (e.g., an SMS message arrived), to application events (e.g., your activity was launched

from the devices main menu).

5.3 System Architecture

The system architecture provides a high level overview of how the functionalities and

responsibilities of the system were distributed or assigned to various subsystems or

components.

The main purpose here is to gain a general understanding of how and why the system

was decomposed and how the individual parts work together to provide the desired

functionality.


24/73



Figure 5.1 Android System Architecture

Android system architecture consists of four layers and their functionalities are as

follows:

1. Linux Kernel

Linux provides the hardware abstraction layer for Android, allowing Android to be ported

to a wide variety of platforms in future. And it is also responsible for memory

management,process management and other operating system services.

2. Native Libraries

These libraries are all written in C or C++,compiled for particular hardware architecture

used by phones, and preinstalled by the phone vendor. Some of the most important native

libraries are surface manager, SQL database, browser engine etc.

3. Application Framework

This layer provides the high-level building blocks we use to create our applications. Most

important parts of framework are activity manager, content providers, resource manager,location manager etc.

4. Applications And Widgets

Applications are programs that can take over the whole screen and interact with the user.

On the other hand, Widgets also called gadgets only operate in a small rectangle of the

Home screen application. Some of the standard system applications which come

prepackaged with the android phone arePhone dialer,email,contacts,web browser,android

market etc.

the search .It comprises of 3 units namely Query Handler, SQLite database and Cursor

Management.

The query handler converts the search criteria into a SQLite query to perform the

search.The query generated is run on the database to obtain the results and these results are

managed by a Cursor Object.The cursor manager helps us to access the data within a cursor

like moving to next row etc. The View Management is responsible taking the search results

and displaying it to the user in the required format.The various components which help us do

this are shown in the figure below.

Finally the Cursor containing the search results is obtained and the data in it is

accessed and the required data is put into an array adapter and this data is displayed into theListView view.In this section, we have identified the individual modules that comprise the

building blocks of our system and have presented a complete design for them. The details of

the design process for each module contains of the following elements:

The purpose of the module:

A description of its functionality using an algorithm.

A description of the types and number of inputs it accepts.

A description of the types and number of outputs it generates.

A discussion of the relationship it shares with any other components.

An overall view of the structure of the system is presented below it shows the interactions

IMPLEMENTATION

The project we have undertaken involves searching mechanism which is used to solve

searching problems in Message Inbox. It involves search by sender, search by number, search

by date and time, display unread messages.

6.1 Details of language used

We have used JAVA language in our project, and Android uses standard JAVA compiler to

compile the source code.

You get a commonly-used programming language (Java) with some commonly used

libraries (e.g., some Apache Commons APIs) along with support for tools you may

beused to (Eclipse).

Android programs are written in JAVA languages and they use JAVA STANDARD

EDITION(SE) libraries APIs.

Android uses a standard Java compiler to compile your source code into regular byte-

codes and then translates those byte-codes into Dalvik instructions.Therefore, the entire

JAVA language is supported, not just the subset.

Compare this to the Google Web Toolkit (GWT), which has its own Java to JavaScript

translator. By using the stock compiler and byte-codes, you dont even need to have the

source code for libraries that you want to use in your applications.

Android supports a relatively large subset of the Java Standard Edition 5.0 library. Some

things were left out because they simply didnt make sense (such as printing), and others

were omitted because better APIs are available that are specific to Android (such as user

interfaces).

Supported Packages

The following standard packages are supported in Android. Consult the Java 2 Platform

Standard Edition 5.0 API documentation for information on how to use them:

java.awt.font: A few constants for Unicode and fonts


44/73



java.beans: A few classes and interfaces for JavaBeans property changes

java.io: File and stream I/O and etc.

Not Supported PackagesThese packages, normally part of the Java 2 Platform Standard Edition,are not supported by

Android:

java.applet

java.awt

java.lang.management

java.rmiand etc.

Additional Packages

In addition to the standard libraries listed earlier, the Android SDKcomes with a number of

third-party libraries for your convenience:

org.apache.http: HTTP authentication, cookies, methods, andprotocol

org.json: JavaScript Object Notation

org.xml.sax: XML parsing

org.xmlpull.v1: XML parsing

6.2 Details of platform used

Android is the first free, open source, and fully customizable mobile platform. Android offers

a full stack: an operating system, middleware, and key mobile applications. It also contains a

rich set of APIs that allows third-party developers to develop great applications.

Android is a new open source software toolkit for mobile phones thatwas created by Google

and the Open Handset Alliance.

Android is the first environment that combines the following:

A truly open, free development platform based on Linux and open source:

Handset makers like it because they can use and customizethe platform without paying a

royalty.Developers like itbecause they know that the platform has legs and is not locked

into any one vendor that may go under or be acquired.


45/73



A component-based architecture inspired by Internet mashups:

Parts of one application can be used in another in ways not originally envisioned by the

developer. You can even replace built-in components with your own improved versions.

This will unleash new round of creativity in the mobile space.

Tons of built-in services out of the box:

Location-based services useGPS or cell tower triangulation to let you customize the user

experience depending on where you are. A full-powered SQL database lets you harness

the power of local storage for occasionally connected computing and synchronization.

Automatic management of the application life cycle:

Programs are isolated from each other by multiple layers of security, which willprovide a

level of system stability not seen before in smart phones.The end user will no longer have

to worry about what applicationsare active or close some programs so that others can run.

Androidis optimized for low-power, low-memory devices in a fundamentalway that no

previous platform has attempted.

High-quality graphics and sound:

Smooth, antialiased 2D vectorgraphics and animation inspired by Flash are melded with

3Daccelerated OpenGL graphics to enable new kinds of games andbusiness applications.

Codecs for the most common industrystandard audio and video formats are built right in,

includingH.264 (AVC), MP3, and AAC.

Portability across a wide range of current and future hardware:

All your programs are written in Java and executed by Androids Dalvik virtual machine,so your code will be portable acrossARM, x86, and other architectures. Support for a

variety of inputmethods is included such as keyboard, touch, and trackball.User interfaces

can be customized for any screen resolution and orientation.

Android offers a fresh take on the way mobile applications interact withusers, along with the

technical underpinnings to make it possible.


46/73



6.3 Details of the Interface

We have implemented the user interface using Activities.

An activity is a user interface screen. Applications can define one or more activities to

handle different phases of the program. each activity is responsible for saving its own

state so that it can be restored later as part of theapplication life cycle

The building block of the user interface is the activity. While it is possible for activities

to not have a user interface, most likely your headless code will be packaged in the

form of content providers or services

Your projects src/directory contains the standard Java-style tree of directories based

uponthe Java package you used when you created the project. Inside the innermost

directory you should find a pre-generated source file named Now.java, which is where

your first activity will go.

TESTING AND RESULTS

The purpose of this section is to ensure that the resulting system meets the system

requirements and there is a seamless transition of data flowing through each of the systems as

well as in between one another.

In our application there are mainly 4 modules which provide the 4 promised features. Each

module has its own user interface. There is an interface which brings together all the 4

features.

We perform three types of testing namely

1. Unit testing

2. Integration testing

3. User Interface testing

7.1 Unit Testing

The first level of testing is called unit testing. Unit testing focuses verification effort on the

smallest unit of software design- the module. In this, different modules are tested against the

specifications produced during design for the modules. Unit testing is essentially for

verification of the code produced during the coding phase and hence the goal is to test the

internal logic of the modules. It is typically done by the programmer of the module. A

module is considered for integration only after it has been unit tested satisfactorily. Due to its

close association with coding, the coding phase is frequently called coding and unit testing.

The unit test can be conducted in parallel for multiple modules.
