Research And Implementation Of Address Book Technology Based On Attenuation Window

With the popularity of the continuous development of the mobile communications industryand the Internet used in mobile devices, networks and users have become increasinglydemanding of mobile terminals. Android is an open mobile device platform, including operatingsystem, middleware and key platform application. The opening platform features of skills inAndroid could promote technological innovation, but also helps to reduce development costs,and also allows operators to easily develop their own characteristics of the product. In recentyears, address book and notepad record number of entries rapid growth, seeking a fast andefficient search technology is highly concerned about. A contact which has a good interfaceand a fast and efficient search technology that could expand to various mobile operatingsystem or even enterprise-class address book applications has a good application prospect.This paper designs and develops a fast and efficient contacts search technology. In thispaper, first of all, a systematic study of the background on the current mobile operatingsystems is introduced. Then the states of mobile operating system and the mechanism of thecontacts commonly used are simply described. Furthermore, the characteristics, architecture,composition and working mechanism of Android are analyzed in detail, SQLite database isalso introduced in detail.This paper proposes the working mechanism of the address book software and introducesthe software interface design principles. In accordance with these principles, the interface ofthe address book was designed. The design principles and process of the contacts searchingmodule were described in the system design, the database design was also made a detailedintroduction. This address book software completed traditionally adding contacts, del etingcontacts, modifying and viewing contacts’ information in the development andimplementation of the software, also advanced searching candidate contacts that searchingcontacts basing on name spelling and full name initials and simulating the thinking style ofthe owners of mobile with Attenuation Window method. Sort the search results by ContactCommunications Tightness to achieve the target which is that we can enter less but get thewanted contact much quicker. Through the application of contrast, the operation of theaddress book based on the attenuation window is more convenient and efficiency that enhancethe practical degree.
