MASTG-BEST-0006 Use Up-to-Date APK Signing Schemes (Android)

Platform: Android
Knowledge: MASTG-KNOW-0003

Ensure that the app is signed with at least the v2 or v3 APK signing scheme, as these provide comprehensive integrity checks and protect the entire APK from tampering. For optimal security and compatibility, consider using v3, which also supports key rotation.

Optionally, you can add v4 signing to enable faster incremental updates in Android 11 and above, but v4 alone does not provide security protections and should be used alongside v2 or v3.

The signing configuration can be managed through Android Studio or the signingConfigs section in build.gradle or build.gradle.kts. To activate both the v3 and v4 schemes, the following values must be set:

// build.gradle
android {
  ...
  signingConfigs {
    config {
        ...
        enableV3Signing true
        enableV4Signing true
    }
  }
}
