About this app

GAMA Native brings the power of the GAMA agent-based modeling platform to your Android device. Run, explore, and experiment with over 850 ready-to-use simulation models — from flocking Boids and ant foraging to flood simulation, epidemiology, and evacuation modeling.

Key Features

- 850+ Models — A built-in library of GAML models spanning biology, ecology, urban planning, logistics, education, and more. Browse, open, and run any model in seconds.
- GAML Code Editor — View and edit model source code directly on your device with syntax highlighting.
- Real-Time Simulation — Watch agent-based models come alive with 2D and 3D displays, interactive parameter tuning, and step-by-step or continuous execution.
- GIS Support — Load real-world geospatial data and run spatially-explicit simulations with built-in GeoTools integration.
- Dark Theme — Comfortable viewing with a built-in dark mode toggle.
- Batch Experiments — Run parameter sweeps and batch experiments without a display.
- Model Workspace — Point the app at any folder on your device to load your own GAML models.

What is GAMA?

GAMA (GIS Agent-based Modeling Architecture) is an open-source simulation platform used by researchers, educators, and students worldwide for building and executing agent-based models. It uses the GAML modeling language designed specifically for multi-agent simulation.

Who is this for?

- Researchers running field experiments away from a desktop
- Students learning agent-based modeling on the go
- Educators demonstrating simulations in the classroom
- Anyone curious about complex systems and emergent behavior

Open Source

GAMA Native is free and open source. Source code and model library are available on GitHub.

Permissions

- Internet: for loading models and data from URLs you specify
- Storage: for reading and writing model files in a workspace folder you choose

What’s new

Removed MANAGE_EXTERNAL_STORAGE, READ/WRITE storage permissions and legacy external storage; manifest requests INTERNET only.
Added androidx.documentfile.
FIX: R8 minify/shrink disabled for release — R8 broke the GAML resource factory at runtime ("A registered resource factory is needed"). This build has minify/shrink off.
