- Checkout code
- Set up JDK and Android SDK
- Decrypt keystore from secrets
- ./gradlew clean assembleRelease
- Run instrumentation/emulator tests to validate SDK behavior
- Upload artifact
iOS (Xcode) integration
Setup
- Add SecureDELTA via Swift Package Manager, CocoaPods, or manual framework embedding according to documentation.
- If the SDK requires run script phases (for symbol obfuscation, dSYM handling, or binary instrumentation), add the script to Xcode Build Phases.
- Configure Info.plist or build settings for SDK initialization flags or API keys, injected via build-time variables.
Example CocoaPods Podfile excerpt:
pod 'SecureDELTA', '~> 1.2.3' post_install do |installer| installer.pods_project.targets.each do |target| # Apply any target-level settings required by SecureDELTA end end CI pipeline steps
- Use macOS runners (GitHub Actions macOS, macOS Jenkins agents, Bitrise, etc.).
- Install CocoaPods or resolve Swift packages.
- Ensure code signing and provisioning profiles are available (stored in CI secrets or a secure store).
- Run xcodebuild with the appropriate scheme and configuration.
- If SecureDELTA requires a post-build script for symbol upload or instrumentation, run it in the pipeline.
- Run UI tests on simulators or device clouds that validate SDK features (tamper detection, jailbreak/root detection).
Cross-platform (React Native, Flutter, Xamarin)
- Add native SDKs to both Android and iOS subprojects following their respective steps.
- Add any JavaScript/Flutter plugin packages provided by SecureDELTA and ensure native linking/integration completes in the CI build.
- Confirm that packaging and build steps for the cross-platform framework will trigger native build steps that include SecureDELTA instrumentation.
Pipeline must build both platform artifacts and run platform-specific tests.
Secrets and credentials management
- Use CI provider secrets (encrypted variables) or a vault (HashiCorp Vault, AWS Secrets Manager, Azure Key Vault) to store SDK API keys and signing credentials.
- Inject secrets at build time via environment variables or files (decrypt in-memory when possible).
- Limit access: only CI jobs that need the secret should be able to access it. Use ephemeral credentials where supported.
Testing SecureDELTA integration
Testing is critical to ensure the SDK behaves as expected and does not break app functionality.
Recommended tests:
- Unit tests covering initialization and API usage.
- Integration tests verifying SecureDELTA features (tamper detection, secure storage access, debug detection).
- Instrumentation/UI tests on emulators and physical devices to confirm runtime protections (e.g., hooking attempts fail, root/jailbreak detection triggers expected behavior).
- Regression tests around performance (measure any build or runtime overhead introduced).
Automate tests in the CI pipeline with clear pass/fail criteria. Consider adding a gate that prevents promotion to production if SecureDELTA-specific tests fail.
Monitoring and release management
- Log SDK initialization and health checks to your app’s telemetry backend (respect user privacy and legal requirements).
- Use feature flags or staged rollouts to limit exposure while monitoring for issues.
- In the pipeline, tag artifacts with metadata indicating SecureDELTA version and configuration used (helpful for audits and rollbacks).
- Maintain a dependency update policy to regularly upgrade SecureDELTA to receive security patches.
Example CI snippets
Below are conceptual snippets — adapt paths and versions to your environment.
GitHub Actions (Android build step):
- name: Build Android Release uses: actions/checkout@v4 - name: Set up JDK uses: actions/setup-java@v4 with: distribution: 'temurin' java-version: '17' - name: Decrypt keystore run: gpg --quiet --batch --yes --decrypt --passphrase="$KEY_PASSWORD" --output android/app/keystore.jks keys/keystore.jks.gpg - name: Build run: ./gradlew clean assembleRelease GitHub Actions (iOS build step):
- name: Build iOS runs-on: macos-latest - uses: actions/checkout@v4 - name: Install CocoaPods run: pod install --project-directory=ios - name: Build run: xcodebuild -workspace ios/YourApp.xcworkspace -scheme YourApp -configuration Release -sdk iphoneos Troubleshooting common issues
- Missing classes after minification: add the SDK’s ProGuard/R8 rules or adjust minifier configuration.
- Code signing errors on iOS: ensure provisioning profiles match the app’s bundle ID and that CI has access to the signing identities.
- Instrumentation plugin failures: confirm Gradle/Xcode plugin versions are compatible with your build tools.
- Test flakiness on simulators/devices: pin OS and emulator versions in CI to reduce variability.
Security & compliance considerations
- Avoid hardcoding secrets in source. Use secure CI secrets or vaults.
- Ensure telemetry adheres to privacy laws and your privacy policy.
- Maintain an audit trail of which SecureDELTA configuration and SDK version were used for each build.
Rollout checklist
- Confirm SecureDELTA SDK version and changelog.
- Add SecureDELTA to build configuration and verify local builds succeed.
- Add required CI steps and secrets, run a full pipeline in staging.
- Execute automated tests that validate security features.
- Perform a staged rollout with feature flags or percentage-based releases.
- Monitor crash/error/logging systems for regressions.
- Promote to production once stable.
Conclusion
Integrating SecureDELTA APP + SDK into your CI/CD pipeline makes mobile app security repeatable, auditable, and part of normal development workflows. The core steps are: plan where the SDK fits, securely manage secrets, add build-time or runtime integration to Android/iOS builds, automate testing, and monitor post-release. With SecureDELTA embedded in CI/CD, you shift security left and reduce the risk of shipping vulnerable or unprotected binaries.
