Play store warning to migrate to Play Integrity API: Critical issues for com.google.android.gms:play-services-safetynet:18.0.1

Play Store Warning: Migrate to Play Integrity API

Background

The Google Play Store has issued a warning to developers using the com.google.android.gms:play-services-safetynet:18.0.1 library. This warning indicates that this library is approaching its end of life and developers need to migrate to the Play Integrity API. Failure to do so could result in app functionality issues and potential removal from the Play Store.

Understanding the Issue

The SafetyNet API, previously used for various security checks and verification purposes, is being replaced by the Play Integrity API. The Play Integrity API offers enhanced security features, including:

• Improved protection against app tampering and spoofing.
• Enhanced device attestation and integrity checks.
• Support for more robust security measures.

Critical Issues with com.google.android.gms:play-services-safetynet:18.0.1

Using the deprecated SafetyNet library presents several critical issues for developers:

• Limited Functionality: New features and improvements will only be available in the Play Integrity API.
• Security Vulnerabilities: The SafetyNet API might be vulnerable to exploits that have been addressed in the Play Integrity API.
• App Store Removal: Applications relying on the deprecated library may face rejection or removal from the Play Store.

Migrating to Play Integrity API

The migration process involves updating your app to use the Play Integrity API. Here’s a simplified overview:

1. Project Setup

Add the Play Integrity dependency to your project’s build.gradle file:

dependencies {
  implementation 'com.google.android.gms:play-services-integrity:17.0.0' // Replace with latest version
  // Other dependencies
}

2. API Implementation

The Play Integrity API utilizes a different structure compared to SafetyNet. You’ll need to adapt your existing code accordingly. Below is a basic example for device attestation:

// Replace with your actual code
PlayIntegrity.getInstance(this).attest(
  context,
  PlayIntegrity.AttestationRequest.builder()
    .setNonce(nonce) // Nonce generated by your app
    .build(),
  new PlayIntegrity.AttestationResultCallback() {
    @Override
    public void onResult(AttestationResult attestationResult) {
      if (attestationResult.getStatus() == AttestationResult.STATUS_OK) {
        // Success!
        // Process attestationResult.getAttestationToken()
      } else {
        // Handle error (e.g., STATUS_ERROR)
      }
    }
  });

3. Code Testing and Deployment

Thoroughly test your updated app to ensure seamless integration with the Play Integrity API. After successful testing, deploy your app to the Play Store.

Comparison of SafetyNet and Play Integrity API

Conclusion

Migrating from the SafetyNet API to the Play Integrity API is crucial for developers. It ensures the security and functionality of their applications while complying with Play Store guidelines. By updating your app and adopting the new API, you’ll enhance your app’s security posture and ensure long-term compatibility within the Play Store ecosystem.
