Android Large Sources Mobile Phone Location Data Management System

With the popularity of Android mobile phones,the massive location data generated by mobile location services has high research value in production and life,but its storage is so complex that it is difficult to obtain and it lacks of classification.At present,the location data acquisition of Android mobile phones is mainly from the location data in the external storage and obtained by real-time.The acquisition method of location data is mainly based on the export of traditional PC software.Location data can not be acquired and transmitted in real time and it lacks a unified coordinate system classification.With the improvement of the security of the Android system,the storage of location data is gradually transfered from external storage to internal storage.The traditional acquisition methods of location data have been unable to meet the needs of comprehensive and realtime data acquisition.Based on the storage characteristics of Android mobile phones,this article uses Java language to develop a management system of mobile phone location data and uses this system to extract mobile phone location data from a national land survey and do optimal path planning,which Improve the work efficiency of field survey of surveying and mapping.The research content of this article is as follows:1.This paper analyzes the Android system architecture,explores the relationship between Android security mechanism,root permissions and data storage,clarifies the key points of location data extraction,divides the location data acquisition methods into internal storage and external storage,clarifies the access API of location data storage.2.This article uses decompilation to obtain the storage architecture of the Android mobile phone application,locate the storage path of location data and summarize the technical path of the location data acquisition,and classify the coordinate of the location data.3.This article creates a mobile terminal of Android location data acquisition,which is responsible for location data acquisition,upload and visualization;creates a server terminal of storage,which is responsible for the classification storage of the location data and the requestment of the PC terminal and mobile terminal;creates a PC terminal of management,which is responsible for data management.4.This paper extracts the location data in the photos of a survey and transforms its coordinates,and proposes the optimal path analysis based on the impedance of the survey point.
