Initialize the REL-ID SDK

⚙️ Overview: REL-ID SDK Initialization

The REL-ID SDK initialization is the first and essential step before any authentication or activation flow. It sets up a secure environment, validates device integrity, and connects to the REL-ID backend infrastructure.

🧩 Purpose

• Establish a secure communication session with the REL-ID server.
• Perform local and remote security checks (e.g., emulator detection, root/jailbreak status).
• Load configuration and prepare the SDK for further operations like login or activation.

🔄 Initialization Sequence

1. **App Calls initialize() **

   • The SDK initialization begins when the app explicitly calls the initialize() method.

2. **Progress Feedback via onInitializeProgress() **

   • This callback is invoked multiple times to notify the app of the current progress (e.g., STARTED, IN_PROGRESS, COMPLETED, INIT_FAILED).

3. Threat Detection

   • The SDK performs both local and server-side threat evaluations.
   • If non-terminating threats are detected:
     • onUserConsentThreats() is triggered, and the app must respond via takeActionOnThreats() to continue or terminate.
   • If terminating threats are found:
     • The SDK emits onTerminateWithThreats() and halts further execution.

4. Error Handling viaonInitializeError()

   • If any issue arises during setup (e.g., misconfiguration, network failure), onInitializeError this event is emitted with error details.

5. Successful Completion

   • Upon passing all checks, onInitialized() is emitted, confirming that the SDK is now ready for user-related operations.

6. Post-Initialization:getUser()

   • The SDK automatically calls getUser() to indicate it’s ready to accept a user ID for login or activation.
     • The app must respond using setUser() .

✅ Best Practices

• Always ensure the SDK is fully initialized before triggering login or activation flows.
• Properly handle onUserConsentThreats() to provide a seamless UX in case of non-critical threats.
• Log or report errors from onInitializeError() for debugging and support.
