This research aims at producing an android-based as the basis for developing mathematics teaching materials in culture called ethnomathematics. The method used in this research is development research or commonly known as Research and Development using the ADDIE approach (Analysis, Design, Development, Implementation and Evaluation). This research was carried out only at the stage of development, currently the research is still on progressing to the next step which are implementation and evaluation. The research was taken place on Java Island with three major provinces, namely West Java, Central Java, and East Java using a multistage random sampling technique, representative, areas were taken as research sample. The result of this research was the development of an android-based application using ethnomathematical element of Javanese batik. The research stages have been neglected, namely needs analysis and ethnomathematical analysis of batik at the research location, and designing the screen display, material content that needed to be included in the application as the material for the application made. The next step is for the team to implement and evaluate that applications that have been made.
