Understanding the Play Integrity API: Google’s Anti-Tampering Mechanism

The Play Integrity API is Google’s mechanism for ensuring the integrity of the Android ecosystem. It’s designed to prevent app piracy, cheating in games, and unauthorized access to sensitive data. The API checks various aspects of your device to determine if it’s a genuine, unaltered Android device running a legitimate version of the operating system.

Key Aspects the API Verifies:

• Device Attestation: Confirms the device is a genuine Android device manufactured by a recognized vendor.
• System Integrity: Checks for modifications to the system image, including rooting, custom ROMs, and other unauthorized alterations.
• Account Licensing: Verifies the user has a valid Google Play license for the app being used.

The Three Levels of Integrity:

Google’s Play Integrity API provides three different response labels, defining different states your Android device can be in. The three labels are:

• MEETS_BASIC_INTEGRITY: the device passes basic integrity tests. The device is running an official version of Android, which has been provided by the device manufacturer, and has passed Google’s integrity checks.
• MEETS_DEVICE_INTEGRITY: the device passes device integrity tests. The device is running an official version of Android, which has been provided by the device manufacturer. The device has passed Google’s integrity checks and meets Google’s device integrity requirements.
• MEETS_STRONG_INTEGRITY: the device passes strong integrity tests. The device meets all the criteria of MEETS_DEVICE_INTEGRITY, and the device has a hardware-backed key attestation.

Common Causes of Play Integrity API Failures: Why Your Device Might Be “Cooked”

Several factors can trigger Play Integrity API failures, leading to the dreaded “cooked” status. Understanding these causes is crucial for effective troubleshooting.

Rooting and Custom ROMs

The most common cause of Play Integrity API failures is rooting your device or installing a custom ROM. By their very nature, these modifications alter the system image and trip Google’s integrity checks.
