ABSTRACT

The Project titled Lock Screen is an android based application that enables people to stop the

unauthorized use of their android powered smart-phone. The aim of the project was to make

user favourable method for the security of their android powered Smart-phone.

In this Project Report we have started with the introduction in which we define about the

android operating system its history then explain about the architecture which give you detail

about the frame-work on which android works

Then we write out on which software this application can be made out with the help of Android

development tools, then we point out what system need to run this application and use its full

features. Then we inserted screen shots of the application like sending pin to the mobile-phone,

security question & answer etc.

After this comes the Test Part, As we know since the application doesn’t have complex or high

end function, we does the manually testing of the application on the required device and on the

Android Virtual Device, in which application run successfully with ease.

Then we discuss the results in which we try to recall all the function we said to develop,

After wards we discuss the conclusion we get after developing this application with the future

prospects of the application in the application. Then we write out all the name of places where

we get resources, books, software to develop this application with accuracy and ease.

1. INTRODUCTION

1.1 HISTORY

Android, Inc. was founded in October 2003 California by the efforts of Andy Rubin who was

co-founder of Danger, Rich Miner who was co-founder of Wildfire Communications, Inc.,

Nick Sears was once VP at T-Mobile, and Chris White which headed design & interface

development of WebTV.

The motive of the company was to develop an advanced operating system which can be used

digital cameras, but when they realised that the market required for that was not large enough

to capture, and they diverted their efforts in producing the operating system which to rival

Symbian and others.

Despite the founders past accomplishments, Android Inc. secretly operated, revealing it was

working on mobile phones software. Google buys out Android Inc. on 17 August 2005.

Android Inc. key employees- Rubin Miner and White stayed in the company after the google

acquisition.

Many assumed that android Inc. at that time was planned to enter the market of mobile phone.

At Android team led by Rubin developed Linux kernel powered mobile phone operating

system.

Google demonstrated the operating system to handset makers and carriers with the vision of

providing a flexible & upgradable system. The Google has taken a series of h/w component

and s/w partners and signalled to carriers that they are open up more co-operation.

On 5 November 2007 Android’s powered mobile device platform built on the Linux kernel

version 2.6.25 is launched. HTC Dream was first commercially available android powered

Smartphone released on October 22, 2008.

In 2010 Google launched series of devices named-Nexus

1.3 GOAL OF PROPOSED SYSTEM

The primary goal of the project is to design, develop and test an Android Application “Lock

Screen”. The proposed system is to enables people to stop the unauthorized use of their android

powered smart-phone. The aim of the project was to make user favourable method for the

security of their android powered Smart-phone.

Our goals in developing the proposed Android Application are:

Accuracy: The level of accuracy in the proposed system will be higher. All operation would be

done correctly and it ensures that whatever information is coming from the centre is accurate.

Access: The Lock Screen has a specially designed interface that will let you do operation easily

& effectively.

Immediate retrieval of information: The main objective of proposed system is to provide for a

quick and efficient retrieval of information.

Easy to Operate: The system should be easy to operate and should be such that it can be

developed within a short period of time and fit in the limited budget of the user.

1.4 SCOPE

Big, easy to use Lock screen Interface.

Full access to all of your Lock method.

Big friendly button, great for quickly getting some operation going.

Large text, brilliant for lock in a rush.

Locking with just a touch on the screen.

Lock orientation.

Ability to lock screen easily without hurting screen lock button.

Easy to access options with just a touch on the screen.

Shiny, reflective, catchy app screen.

Horizontal mode orientation.

Provide Security to your Android Smart-Phone.

Use low battery in running since it is not using most of services.

1.5 SOFTWARE USED

1.5.1 ECLIPSE

IBM VisualAge is the initial codebase. For java developers the eclipse SDK which includes

the java development tools is really meant a lot.

Users can enhance their eclipse platform for developing in different programming language by

simply installing plug-ins in eclipse & they can also make their own plug-ins which can used

Lock Screen

12

in the eclipse SDK. Eclipse SDK is open source software although it is not compatible with

GNU General Public License. It is one who run under GNU Classpath & can be easily run

without in IcedTea.

Plug-ins which are installed in the eclipse provide more functionality to the developers with in

& on top of the runtime system vs some others whose functionality is hard coded.

Eclipse runtime system is on Equinox, which is an implementation of OSGi Framework

specification.

In Eclipse everything is a plug-in with the exception of small run time kernel which also mean

that every plug-in are integrates exactly same ways as other plug-in which is said to be created

equally in terms of the features.

Eclipse SDK offers a java developers with built in java compilers with a full java source files.

This allows advanced code analysis

1.6 TOOLS USED

1.6.1 ANDROID SDK

The android software development kit consist of many packages. It is extensively used for

development of android application. The SDK get linked with the eclipse & provide the whole

integrated development environment for the application development which will run on the

android operating system powered smartphone.

Software development kit consist of debugger, libraries, documentation, sample code,

tutorials, emulator which run similar like a handset devices & it has some default handset

devices profiles.

The project has been completed successfully which covering the maximum requirement given

by Industry Mentor. The constraints has been met and overcome with success. The system is

designed as like it was decided earlier in design phase. The project gives good idea on

developing a user-friendly application which satisfying different user.

The system is made flexible and versatile. This application has a user-friendly screen that

enables the user to use the lock screen application without any inconvenience. Validation

checks induced have greatly reduced errors in the lock screen application. Provisions have been

made to upgrade the lock screen application. The application has been tested with live user and

has provided a successful result. Hence the application has proved to work efficiently.

The system created met its objectives, by being simple to use, will be easy to download from

app store. This software is developed with scalability in mind. Additional modules can be easily

added when necessary. However there is still a lot of scope for future improvement and add on

in functionality. Some of the major ones being developing for other mobile operating system

like windows, etc.

7. FUTURE PROSPECTS

The Future Prospects are as follows:

Applications in Android platform are growing at unimaginably high pace. Android has rapidly

become the fastest-growing mobile OS with largest installed base. Every day more than

900,000 new Android devices are activated worldwide. Android’s openness has made it a

favourite for consumers and developers alike, driving strong growth in app consumption.

Android users download more than 1 billion apps and games from Google Play each month.

With its partners, Android is continuously pushing the boundaries of hardware and software

forward to bring new capabilities to users and developers. For developers, Android innovation

lets us build powerful, differentiated applications that use the latest mobile technologies.

Google Play is the premier marketplace for distributing Android apps

I propose to continue my development activities in Android, Java to be part of the ongoing

Innovations happening in the Industry.

I also would seek to found a company to slowly build on Android development leveraging

Google App Engine.

I hope to work under the guidance and facilitation of the Amity faculty to interact with the

Industry (both Developer community and Hardware manufacturers) for enabling me to

undertake live projects as per requirements of the Industry.
