CSLA – An application using Android Capstone Project
This paper presents the class and staff Locator Application (CSLA) using Android Capstone Project. Locating staff and class room for the students in school, colleges or universities is a challenging task. CSLA helps to locates staff and class room based on the time table data provided to the application. As such, the application will save time of students during the study hours. Currently, this locator application is being tested at Guru Nanak Dev Engineering College (GNDEC), Ludhiana for use in future.
SQLite is the database system used in this capstone project application for storing data. Output generated by the application is retrieved from SQLite. Location based services are used to pin point the user location and show the route to be followed from the source to destination point. Java is used to program the application and the user interface is created using Extensible Markup Language. The android providesstructured data persistence through a combination of SQLite databases and content providers. A.Sqlite Database: SQLite is an open-source, light-weight and relational database management system. In android software stack it is included as compact C library. Each android application separately includes sqlite database which reduces external dependencies, minimizes latency and simplifies transaction locking and synchronisation of application. It is stored in databases folders on android devices or emulators [8]. Codeshoppy
Content values are used to store values that content resolver can process. Put method is used to store data using content value. Cursor represents the results returned by the database query. It points to first row of the query result [8]. Move to First method is used for moving cursor to first result returned by query. MovetoNext and MovetoPrevious methods are used to move cursor to next row and previous row. GetCount method is used for returning total number of rows. GetColumnName method is used for returning name of the specified column index.Location based services enable user to find the current location of the device. These services use longitude and latitude for the precise geographic location of device. The map library is used to convert the longitude and latitude values into street address which users can understand easily. Location based services include Maps, MapActivity and Location based API which are used to show the location on the map. Map View is used to display a view of map. MapActivity is used for controlling MapView. Location based API is used to get user’s current position and display that location on map. Location Manager class is used to get the coordinate values
