Google Play Games on PC supports integrity protection through the Play Integrity API and several other Google Play features to help ensure that your game hasn't been tampered with or installed from an untrustworthy source.
Play Integrity API
The Play Integrity API helps protect your games from potentially risky and fraudulent interactions. The API enables you to reduce attacks and abuse such as fraud, cheating, and unauthorized access. The Play Integrity API replaces the SafetyNet Attestation API (SNAA) and Play App Licencing API. SNAA does not work with Google Play Games on PC.
Device Integrity Field
The
deviceRecognitionVerdict
field contains a single value, deviceRecognitionVerdict,
that represents how well a device can enforce app integrity. By default,
deviceRecognitionVerdict can have one of these values:
MEETS_DEVICE_INTEGRITY: The app is running on an Android-powered device with Google Play services. The device passes system integrity checks and meets Android compatibility requirements.MEETS_VIRTUAL_INTEGRITY: The app is running in a virtual Android environment with Google Play services, currently limited to Google Play Games on PC. The environment meets core Android compatibility requirements and passes Google Play integrity checks.- None (a blank value): The app is running on a device that has signs of attack (such as API hooking) or system compromise (such as being rooted), or the app is running on a non-physical device (such as an emulator) that does not pass Google Play integrity checks.
The Play Integrity API uses the deviceRecognitionVerdict value
MEETS_VIRTUAL_INTEGRITY to indicate that the game is running on Google Play Games on PC. Here's an example of a passing response from
the Play Integrity API:
deviceIntegrity: {
// "MEETS_VIRTUAL_INTEGRITY" indicates the game is running on Google Play Games on PC
deviceRecognitionVerdict: ["MEETS_VIRTUAL_INTEGRITY"]
}
If you have a cross-platform game available on both mobile and
Google Play Games on PC, make sure your
validation logic checks for both MEETS_VIRTUAL_INTEGRITY and
MEETS_DEVICE_INTEGRITY.
Automatic protection
Google Play's automatic protection is a service that helps you protect your game against unauthorized redistribution and piracy. When users get your protected app from an unknown distribution channel, they'll be prompted to get your official app from Google Play. Automatic protection works in your app without a data connection. It can be turned on with one click in the Play Console, and requires no developer work before testing and no backend server integration. Automatic protection can add the following features to your game:
- Installer checks: Automatic protection can add Google Play installer checks to your app's code that happen at runtime when your app is opened. If the installer checks fail, users will be prompted to get your app on Google Play.
- Anti-tamper protection (this feature is only available to selected Play partners): Automatic protection can add runtime checks to your app's code to detect modification and use advanced obfuscation techniques to prevent the checks from being removed or reverse engineered. If the checks fail, the user will be prompted to get your app on Google Play or the app will not run.
Automatic protection requires no code changes or developer work before testing. Learn more about automatic protection in the Play Console help center.
