Computer science and technology has become the vital role to change the geological teaching modes. The Xingcheng Geological Teaching Practice of Jilin University, as a pivotal practical component within the Earth Science Division, faces escalating demands for digital transformation in the digital era. This paper describes the educational purpose and the role played by the Xingcheng Geological Practice Platform; in order to extend the Xingcheng Geological Practice Platform, we leverages the Android Studio development framework to construct a mobile App for Xingcheng Geological Teaching Practice. The App employs a GridView widget for categorized functional panel management, integrates a ListView widget for real-time notification display, and establishes a hierarchical route navigation system using an ExpandableListView widget. To meet the requirements for real-time data synchronization, the system incorporates Long Polling technology for instantaneous password management and user status updates, while implementing a secure authentication architecture based on the OAuth protocol. The results indicate that the modularly designed App effectively delivers essential pedagogical functionalities, including route planning, geological phenomenon observation, and data collection. This App provides innovative digital tools for Xingcheng Geological Teaching Practice and offers scalable technical references for similar practical education platforms. Furthermore, we envision scenarios for integrating Xingcheng geological practice with some new technologies. © 2025 IEEE.
