Aplicativo android para gestão de custos, manejo e resultados em lavouras

Abstract

Mobile devices are becoming increasingly important as facilitators of access to information and services in the agricultural sector, especially in developing countries. However, challenges such as limited digital literacy and low connectivity in rural areas still hinder the adoption of more advanced technologies. This work aims to develop an Android mobile application for managing costs, management and results in crops, aimed at small and medium-sized farmers. With an intuitive and accessible interface, the system allows detailed recording of each stage of cultivation from soil preparation to harvest and generates consolidated financial reports in Portable Document Format format, as well as financial dashboards for Productivity, Cost Distribution, Profit × Loss and Profit Margin. The app also offers a notification system, area demarcation tools based on the Google Maps Application Programming Interface and Global Position System, as well as queries to APIs for foreign currency quotes and weather data. The application is also designed to operate offline, allowing the main functions to be used even in areas with poor connectivity. Developed in Kotlin with SQLite, modular architecture and Android Studio as the development environment, the app has had its main screens validated by real users, proving its adherence to the agricultural context and effectiveness in supporting planning and decision-making in the field. The combination of an intuitive interface that is extremely aligned with the producer's needs guarantees easy adoption, efficient control of crop costs and daily support for activities in the field.
