Android apps today run in hostile environments — cloned APKs, rooted devices, emulators, runtime instrumentation, token farming, and automated abuse are no longer edge cases. Client-side checks alone are not enough.
Play Integrity Attestation provides server-verifiable signals that help you assess:
- Whether the app binary is recognized and untampered
- Whether the device meets integrity expectations
- Whether a request is fresh and bound to a specific action
But Play Integrity is not a verdict engine. It’s a signal source that must be verified and enforced server-side, combined with other controls, and applied using risk-based decisioning — not binary allow/deny logic.
In the full guide, I cover:
- Standard vs Classic Play Integrity API (and when to use which)
- Correct request binding using
requestHash - Kotlin client implementation
- Mandatory backend decoding and verification
- A production-ready enforcement model (GREEN / YELLOW / ORANGE / RED)
- Common anti-patterns that break real users
