The people of Indonesia have a wide range of traditions and customs, as well as religious activities. The public's interest in Indonesian religious activities has grown as a result of the diversity of religious activities carried out by Indonesians. Multimedia has an essential role in allowing individuals to obtain information fast, especially as technology advances. As a result, in order to obtain information centrally, the public must search for appropriate information, which takes time. In circumstances like these, the issue is creating and developing an android-based multimedia system application that may assist the public in learning about the Indonesian people's religious activities. This study intends to assist Indonesians in obtaining information on their religious activities, so that they may quickly obtain information and learn about and comprehend their religious activities. The Luther–Sutopo version of the Multimedia Development Life Cycle (MDLC) was utilised, including stages for idea, design, material gathering, assembly, testing, and dissemination. This study led to the development of an Android-based multimedia system for religious activities among Indonesians.
