Project Definition:

            This is a mobile application for people who are concern with their health issues. Not only general people but also with some problem like obese, thinness, diabetic person etc, Can use this application.

Preliminary Investigation:

At this stage we had to perceive the problem and opportunities. We went to a health care center Prevention Health Care to review the existing system. We had to find out initially what the activities they are performing are, how they analyze user and how diet plans are created for particular person. we found out that, such proposed system would be possible to make within given scope and it might be a feasible solution for the users.

Selecting the project development strategy:

As we had developed android application, we had to follow object-oriented strategy for system development. As android is java based development tool which is pure object-oriented language.

Do Not Disturb Incoming Call Manager Android Application

Project Title: ‘Do Not Disturb Incoming Call Manager’

Project Technology: Android

Scopes of Project:

  • It allows user to define which calls from the contacts/numbers to be blocked, allows editing and deleting blocked contact list.
  • User can synchronize the contact list from phone.
  • Application allows the User to define Schedule in terms of date & time in a day of week.
  • It allows User to select criteria for blocking incoming calls in four ways:

1)   Block all incoming calls

2)   Block incoming calls from only blocked numbers

3)   Block incoming calls from Unknown numbers

4)   Block incoming calls from blocked numbers and Unknown numbers

  • It silent the incoming call if it falls in defined criteria.
  • Then it sends one SMS (Text Message) to the caller with the text predefined by the user.
  • By saving configuration user can anytime start or stop whole ‘Do Not Disturb’ service using a single button click. 

Do Not Disturb Incoming Call Manager

Tools and Technologies:


  • Android

Front End Tools:

  • Eclipse IDE
  • Eclipse provided Android – Device Emulator
  •   Android Software Development Kit (SDK)

Back End Tools:

  • Db4o Database Engine

(It is a database engine open source object-oriented, its acronym is Data Broil 4 (for) Objects. It is developed to work with developments in Java and .Net. Db4o runs on any operating system that supports these languages.) 


Project Definition 

It is an application for mobile phones using the operating  system  Android  whose  function is to automatically mute  calls to contacts has previously been defined as blocked in a time  frame,  both  times  as  daily.  Once  the call  has  been ended,  Do Not Disturb leave the phone in normal mode both volume and vibration.  It also provides added functionality such as send warning messages indicating that you are sleeping (or busy).

Preliminary Investigation 

The idea about the project is got from the requirement for not to be disturbed by a call from others at some specific time. The application is for android phone, so the development to be done using android technology. In order to block (mute) the incoming call, we have to get the number and check that whether it falls in Blocking criteria, if it is then change the Phone state to silent (if it is General) and on ending the call change state to General and send auto reply. 

Selecting the project development Strategy 

Since the technology used is android for this application and android uses java as base language for programs I have selected the Object Oriented System Development (OOSD) as the development strategy. Again the entities involved in this application can be considered as Objects and we can also store those Objects in the database. So I have used the Database Engine db4o.  

Buddies Hub – Keep in Touch Android Project

SMS service is provided by the Carrier and they take charges to use that service. People now a day’s paid so many charges to use this SMS service.

Simple SMS service is works as first Mobile-x sends message to mobile-y so that first of all it goes to MSC server. MSC server sends that message to centralized SMSC server. Centralized SMSC server sense the receiver phone number and forward same message to receiver i.e. mobile-y network’s MSC server. MSC server push that message to mobile-y and it gets the message which is send by the mobile-x.

Buddies Hub Android Apllication

If sometimes MSC server get too many connection at that time the delivery period of the SMS will be increased and message is delivered late to receiver.

Sometimes if carrier network is down than your important message will not deliver instantly. You send you message to your friend in the morning and it will be delivering to your friend at night or else in the evening.

Carrier charges is now a days little bit low in case of you want to sent message in the local state. But while if you want to sent message outside of your state than it will be little bit costly and if you want to sent message out side of your country then it will be more costly.

To make SMS service more cost effective and fast delivery of the message here I am going to introduced with new application named as “Buddies Hub – Keep in Touch

Buddies Hub – Keep in Touch is an application in which user can able to send message with his friend without use of the carrier Short Message Service (SMS).

BuddiesHub application is works on the device which have Android platform. Now a day’s Android is fastest growing technology in the mobile market.

This project is developed to use Android operating system. Android is an object oriented operating system to mobile devices using a modified version of the kernel Linux.

When user install apk file of my project first of all user has to register him with that application with the help of his mobile number.

Once he is successfully registered with the application then he can login in the application with provided mobile number and password to send messages to his friend.

After successful login user can able to send message to his friend and check inbox for any new message is received by him.

Main functionality of this application is that user can sent message to his friend and desired person without any cost of the carrier charges only one thing is required is that it must be connected with the internet connection.

This application basically works on the platform of Hyper Text Transfer Protocol (HTTP).

When user send message it will go to server on which database resides and when receiver opens inbox at that time it will recall its message from remote database and display in inbox. User can also reply of that message and forward it also.

  1. Planning

At present people are using carrier service to send message and they will charge from the user for that service. This application allows user to send message to another user of this application based on web.

My project planning is that I want people become aware of the free message sending facility. 

Project definition 

“Message sending Application based on Android without use of carrier SMS service” is the main goal of this system.

In this application there is a server which maintains the database of the application and stores the message of all the applicants.

Registered user can send the message to other registered user with the help of internet. 

Preliminary Investigation

  • Once I my father got a call from our relative who lives out of India asking for phone number of another relative at that time in call my father gave him phone number but because of some reason he did not note down it correctly so that after some time again he call to my father and asked for sending him text. At that time that charges to send text was too much high and also call charges to my relative was too much because of ISD call at that time I found that these problem could be resolved through available techniques known to me.

Selecting project Development Strategy

  • Buddies Hub – Keep in Touch project developed for Android device using (OOSD) Object-Oriented System Development because Android is Java based and Java is pure Object Oriented Programming Language.
