Protection coverage in split APK distribution

Signing, migrations, supply-chain integrity and store delivery.

Build and distribution1 min readEditorial methods

An Android installation may contain several splits. Testing one local APK may miss parts of actual distribution.

Evaluation approach

Review language, architecture and feature splits. Test device-specific packages generated by the distribution tools.

Application example

Verify the ABI split containing a sensitive native library separately.

Limits and considerations

A working universal test package does not prove equivalent behavior for every store variant.

Does every device receive the same code?

Architecture, language and features can change contents. Demonstrate that required protection libraries exist in every relevant installation, not only the development device.

Checks and decisions

  • Inventory splits
  • Install device packages
  • Verify critical components
