React Native Android app for the Avni field data collection platform.

• A Linux or macOS shell — the build is Make + bash. On Windows, use WSL2: follow the step-by-step guide in docs/dev-setup-windows-wsl2.md.
• Node 20 via nvm (version pinned in .nvmrc)
• Java 17
• Android SDK: platform 35, build-tools 35.0.0, NDK 27.1.12297006
• An Android device or emulator visible to adb
• Access to an Avni server with an implementation deployed (its URL goes in dev.json below)

git clone https://github.com/avniproject/avni-client.git
cd avni-client

nvm install     # Node version from .nvmrc
make deps       # npm install + patches + prebuild
make test       # optional: verify unit tests pass

cp packages/openchs-android/config/env/dev.json.template packages/openchs-android/config/env/dev.json
# edit dev.json and set SERVER_URL to your Avni server

Then in two terminals:

make run_packager   # terminal 1 — Metro bundler
make run-app        # terminal 2 — build, install & launch on the connected device

Sign in and press the sync button in the app to pull the forms and master data for your implementation.
