CHAPTER ONE
INTRODUCTION
In today’s modern world coupled with the advancement in technology, we have seen a huge increase in the number of mobile users in the world, hence there is need to enable these users record notes instantly in their phone without the need for searching any extra resources like a notebook, pen etc. This is a note recording application that provides a friendly interface for instantly recording information. This will make note taking to android users as easy as storing and accessing contacts.
 Most people carry their phones and use them frequently for various tasks. The trend shows that the growth of mobile phone subscriptions has been growing rapidly. The latest statistics from The International Telecommunication Union (October 2014) shows that there will be 5.3 billion mobile subscriptions by the end of 2015. That is over 70 percent of the world population. These phones are not only used for communication. Lately there is an increasing interest in using mobile phones for interaction with people, places and real world objects. People can use their mobile phones to take pictures of visual markers such as data matrix codes. After recognizing the code, the information related to the code is displayed on the phone. GPS positioning is used for various location based services, such as “find nearest restaurants”. Other areas of mobile interaction are smart objects such as advertisement posters.
One of the building blocks for this trend in ubiquitous computing and communication is the easy and natural interaction between humans and technology. Acquiring information, initiating actions, transferring data, performing financial transactions, etc., can be done by touch-based interaction, which is a way of establishing connections and exchanging information between mobile devices just by bringing them close to each other. It is interesting to see how technology can be utilized in an academic environment.
Expert Note Recorder is the technology that satisfies the need of those who want to take fast and easy note. The Expert Note Recorder provides facilities for people to take note with their android device be it android phone or tablets. The recorded note will be stored in the phone memory which can be read later for reference purpose. This application is very useful in taking note in the class since according to the mobile world statistics, it is found that the number of android mobile users is up to 89%. The reason why an android platform was chosen for the application is due to the fact that it is cheaper when compared to other mobile devices on different operating systems.
1.2 Background of Study
Android is the most popular mobile platform in the world. Android development is becoming an increasingly popular field. For developers who want to target a huge, diverse audience, the use of computer system software has been implemented from PC, mobile and even other means of technology and Applications / Games are now invading it. In recent years, Games are also being implemented by the use of the World Wide Web. Programmers and developers continuously discover and develop new faces, styles of games or applications which most of the people were looking forward to. In line with this, several android applications are being developed running to the tablets. Most are for gaming, application system, knowledge base system and data processing.
An Android application (commonly known as an app) is a program for smartphones running the Android operating system. Writing applications for mobile devices requires some extra consideration compared to writing traditional desktop applications. A smartphone, compared to a desktop computer, has very limited resources. The processor is slow, the memory is limited and power usage should be kept as low as possible. Interruptions (phone calls, text messages, etc.) may occur at any time or the device may simply run low on resources and suspend/kill applications.
