Abstract:

Mobile devices, such as tablets and smartphones, have continuously modified people’s habits and relationships in various areas of their lives. Currently, the ease of access to these devices has caused a growing number of people to have one or more devices and know how to handle them. The relationship between mobile technologies and education is growing in the teaching-learning scenario. Therefore, mobile learning becomes a reality, allowing access to educational content and knowledge sharing with autonomy, regardless of economic, social and geographical factors, through mobile interaction platforms. In this context, institutions that work with Distance Education (DE) need to update and adapt their processes to these innovations. Considering this trend, Saite Group has built, in partnership with the Open University of Brazilian National Health System associated with the Federal University of Brazilian National Health System , a virtual library that enables fast and free access to its contents using mobile devices: Saite Store. This tool enables the dissemination of knowledge with quality. Its content is mostly aimed at health professionals, since the training of workers in this area imposes the need for permanent qualification and innovation of educational practices, in a dynamic and systematized way. Currently, Saite Store already has more than 200 e-books distributed in 12 thematic areas. It is used by more than 21,860 users, proving to be useful in the democratization of the knowledge offered by *blind*. With the expansion of the tool's use, the institution invested in a new version to provide a better experience to its users. A new database architecture has been implemented for the server environment and the user's mobile device. With the operation of this data structure, the use of the offline application was allowed, since a mirror of the service is provisioned at the client. In addition to the change in navigability, the new Saite Store also has a greater capacity of books storage than the previous version, mainly because of the improvement in the application's speed. The new version has optimization algorithm for data provision and only once a day a mirror of the data that the application needs is generated. Two algorithms are used on the server: one to create a file with all available information and another only for new information. Another interesting change is that the new Saite Store brings a more flexible design than the previous one and now the student has a tool more compatible and adaptable to different devices. It was sought to understand how the user uses his device and then a version that is better suited to reading was built - be it horizontal for tablets or vertical for smartphones. Specific versions were also developed for smartphones, adapted to the guidelines of each of the operating systems (iOS, Android, and Windows). According to the Google publisher (Play Store), the application's acceptance in approved devices has reached 100%. In this paper, we dealt with the details of the version for Android devices. This paper aims to perform a detailing of the Saite Store new version, showing its operation and the technological implementations carried out. Finally, the importance of performing updates in the application is highlighted, considering its great potential for use by more than twenty thousand users.
