With the advent of technology, smartphones have taken over our lives in more ways than we can imagine. In the past few years, adoption to smartphones has increased nationwide and across the world. According to the Pew Research Center it has been noted that almost two-thirds of Americans own a smartphone, and 19% of Americans rely to some degree on a smartphone for accessing online services and information and for staying connected to the world. In this era of technology and smartphones, the easiest way to make any information available to a large set of users is through a smartphone application. These applications are absolutely user friendly and present information in the most readable way. As a student in San Diego State University, long hours of studying during finals week in the library made me realize that an application about information related to the SDSU library would come in very handy to a large number of students at SDSU. Imagine not having to run to the library to check if the text book that you want to make notes from is available or not. All of this by clicking on your smartphone application to get all the relevant information. This thesis implements an Android smartphone application with features to get information about the SDSU library. The user of this application can view all the books, media, ecopies of all the available resources in the San Diego State University Library. The application should have the capability for searching catalogues in the library when a user types in a keyword related to the books and media that the user wants to search. There are additional features where the user can view all the planned events and news pertaining to the library. Information about hours of operation, library staff is also provided. The application also has a feature called campus finder which provides the user with the map to the library and information about various departments.
