Android 7.0+. Required AARs: sdk + sdk-secure. Call ResourceCollector.collect only after consent; environment/rootbeer are optional modules. RootBeer adapter needs Maven com.scottyab:rootbeer-lib:0.1.2.
Backend-only integration: copy server/businessguard into your Go backend; HashRequest generates the request binding, Authorize checks the permit before business execution. Your database must enforce unique operation IDs; payment providers must use the same idempotency key. Never expose the backend app key or permit token to an APK.
See docs/environment-0.5.md for sources, test coverage and hardware/network limitations.
