Design And Implementation Of The Android-Based Mobile Phone Group Delete Contact Module

With the development of mobile Internet technology, mobile phones, communications equipment as the most commonly used in our daily lives, in the function and more powerful. Good convenience and openness of the Android operating system platform, making the Android operating system mobile phones getting more and more favorable. Mobile applications will also be rapid development of mobile phone users now for the operability of the application software as well as high demands on the design of the software in other aspects of humanity. This will make the user-friendly mobile phone design has become a very important part of the mobile application development. The contact phone features an indispensable module, the main record the user’s contact data, user-friendly and efficient operation and use, but also delete contacts convenient operation. The system can also be used for the user to create a new user experience. Delete a contact as a business phone, and sometimes we need to be a contact Delete, especially not deleted, but by selectively delete contacts in the phone one by one manually delete, which is too much trouble more none of the half-hour will not be completed, there is an easy way is to use the Android phone bound Gmail account will sync contacts to the phone, the contacts on the opposite Android phone can also choose to sync contacts to Gmail accounts or contact Select the function group to delete. Delete a contact group of Android-based mobile terminal, interactive sharing of resources of the two platforms, the PC side, can also import SIM card contacts group to delete a significant increase in convenience with the Gmail accounts for synchronization delete operation.Were studied and analyzed the workflow of the Android mobile phone platform, and completed in full control of the Android mobile operating system works on the basis of the delete function based on the Android Contact crowd, Design and Implementation.In this paper, the following aspects:First introduced the concept of the Android operating system, the relevant background of the entire Android platform, the development history and current situation analysis overview.Second, the architecture of the Android operating system, the study concluded, and its working process, master of the Android system works.Third, the group delete the contact module needs analysis. Delete contacts for now as a business on the phone, often need to delete contacts, especially when delete more contacts manually delete one by one, it is very inconvenient, which need to be able to have a group to remove the contact functionality for users to create a better user experience.Fourth, the group delete the contact module outline design. The emphasis is on analysis and design, to determine the overall structure is removed from the contact module contacts delete interface, contacts, delete function, the design of the database structure, and contacts related to the processing of the data flow.Fifth, the detailed design of the group to delete the contacts module. The decomposition of the outline design, do the various functions related to the contact to delete module is described in detail, such as the operation of the database, contact list, delete, synchronization operations are carried out the program code and process analysis and design.Sixth, the test group to delete the contacts module. Based on the demand test to detect whether the contact group to delete, synchronize contacts them in alphabetical order, quick swiping motion, and there are more than two thousand contacts.The group delete contacts project is designed to meet the majority of consumers, with the rapid development of mobile applications, remove the contact from the Android-based application will be more popular.
