## Best practices

- **Initialize the SDK on application load**, not on the capture button click. Authentication with the backend takes a few seconds and, if done together with the camera opening, creates a perception of lag.
- **Do not use bridges** to implement the native Android SDK inside Flutter. Use the [official Flutter plugin](/developers/sdks-and-tools/flutter/requirements).
- **Keep the SDK updated.** Unico is not responsible for issues in deprecated versions.

## Sample app

Official Android applications with a complete SDK integration, demonstrating the main flows. Use them to validate your integration before going to production.

| Flow | Description | Repository |
|---|---|---|
| Liveness | PoC in Kotlin that implements biometric selfie capture | [GitHub — unico-sdk-poc-kotlin](https://github.com/unico-labs/unico-sdk-poc-kotlin) |
| User Journeys | PoC in Kotlin that implements the full user journey flow | [GitHub — unico-sdks-poc-kotlin](https://github.com/unico-labs/unico-sdks-poc-kotlin) |
