## 🚀 Getting Started

### Android Development

> [!NOTE]  

> We recommend using Apple silicon Macs for development (arm64), if you're using Intel Mac, you need to add `x86_64` to `targets` under `cargoNdk` in `build.gradle.kts`.

1. Download and install latest [Android Studio](https://developer.android.com/studio)

2. Install JDK 17, preferably using [SDKMAN](https://sdkman.io/)

3. Install `just` by running `brew install just` if you don't have it already.

3. Run `just bootstrap` to install all nessesary tools (Rust / NDK).

4. Generate a GitHub personal [token](https://github.com/settings/tokens) with `read:packages` permission and add it to your `local.properties` file:

```properties

gpr.username=

gpr.token=

```

Optionally, you can generate models and kotlin bindgen by running `just generate`, Gem Android consumes wallet core library as a local module, if you need to update it, ping us or create an issue on [here](https://github.com/gemwalletcom/wallet-core-release).

## 🔐 Security Scanning

We run [MobSF mobsfscan](https://github.com/MobSF/mobsfscan) to catch insecure patterns in our Kotlin/Java sources.

- **Local usage**: Install [`uv`](https://docs.astral.sh/uv/getting-started/installation/) and run `uv tool install mobsfscan` once. After that, `just mobsfscan` (internally `uv tool run mobsfscan -- --type android --config .mobsf --exit-warning`) scans the Android codebase with the repo-wide configuration and fails on `WARNING` and `ERROR` findings.

- **CI enforcement**: `.github/workflows/mobsfscan.yml` runs the same command on every push/PR to `main`, uploads a SARIF report to GitHub code scanning, and fails the workflow if issues remain.

Only suppress detections when you fully understand the risk—ideally fix the code; otherwise, add a targeted `// mobsf-ignore: rule_id` comment with context.

## ♻️ Reproducible Release Verification

See `reproducible/README.md` for the Docker-based verification workflow, prerequisites, and known gaps. You can also grab the latest CI-built APK from the Docker workflow artifact `gem-android-apk` on GitHub Actions.
