PairIP and Google Play Automatic Protection

What automatic protection changes

Google Play adds checks to protected builds and can prompt users to install the official app from Play. Google also documents anti-tamper features and device checks. Compare the delivered Play build with the package under analysis before drawing conclusions from a sideload failure. Google’s automatic protection documentation.

Identify the build, then trace it

Names such as PairIP and libpairipcore are useful search terms. A filename alone does not establish the active checks, exported functions or return values. We inspect package contents, the application entry point, native loading and callers in that APK.

Record the APK hash, signing certificate, version, ABI, install source and split APKs. A missing split or a different install route can change startup before any API request occurs. Compare runs using the same account and app version.

Separate local checks from server decisions

A local install prompt, process exit and HTTP 403 are different observations. A 403 alone does not identify a signing fault or prove that protection passed. Compare the response body, session, request bytes and any integrity verdict used by the server.

Play Integrity provides verdicts that a backend can use in its own decisions. Automatic protection and Play Integrity need separate analysis; one name does not establish use of the other. Play Integrity overview.

Android Keystore keys can be non-exportable and bound to secure hardware. A server that requires proof from that hardware has a runtime dependency that copied code cannot remove. We check this during the APK review and state the deployment requirements before the quote. Android Keystore documentation.

See the package inspection guide and request replay guide.

The full APK is the project

You receive Python, JavaScript/TypeScript, Postman and API documentation for the full application. The work covers endpoints, authentication, request signatures, encryption, decryption, sessions and backend workflows.

Run the complete public demonstration to inspect one matching workflow in every format.

Send the APK on WhatsApp or email. The 24–72 hour delivery window starts after we receive the APK and any account access needed to run it. The fixed quote states the deadline. Most projects finish sooner.
