Initialization of the IdpSdk

The IdpSdk initialization process involves setting up the necessary configurations and initializing the IdpSdkNativeInterface.

Dependency​

Add the IdpSdk AAR to your build.gradle:

debugImplementation(
    name = "idpsdk-debug", ext = "aar",
    group = "com.kobil", version = "0.7.2973720"
)
releaseImplementation(
    name = "idpsdk-release", ext = "aar",
    group = "com.kobil", version = "0.7.2973720"
)

Prerequisites​

Ensure you have the following available before initializing:

  • tenantId: The identifier for your IDP tenant.
  • idpUrl: The base URL of the IDP server.
  • certificateChain: The trusted SSL certificate as a byte array, loaded from your assets.

Android/Kotlin​

Initializing IdpSdk (Android/Kotlin)
class IdpSdkApp : Application() {

    companion object {
        const val TENANT_ID = "your-tenant-id"
        const val IDP_URL   = "https://your-idp-server.example.com"
        const val CERT_FILE = "your-certificate.crt"
    }

    override fun onCreate() {
        super.onCreate()

        val certificateChain = assets.open(CERT_FILE).use { it.readBytes() }

        // initIdpSdk(tenantId, idpUrl, certificateChain, shouldHashPin)
        IdpSdkNativeInterface.initIdpSdk(TENANT_ID, IDP_URL, certificateChain, false)
    }
}

NOTE: The IdpSdk must be initialized via initIdpSdk before calling any other IdpSdk method.

Master Controller Setup​

The IdpSdk relies on the MC-SDK to exchange events with the server. Before using any IdpSdk flow you must:

  1. Set up a SynchronousEventHandler — this is your communication channel with the Master Controller. See Communication with the MasterController for implementation details.
  2. Trigger a StartEvent — this initialises the MC-SDK session and returns a StartResultEvent containing the sdkState that tells you whether activation or login is required. See Start/Restart Event for details.

NOTE: MC-SDK events such as GetAstClientDataEvent and SetAuthorisationCodeEvent will fail if a StartEvent has not been successfully completed first.

Authorization Flow​

After both the IdpSdk and MC-SDK are initialised, all IdpSdk operations (activation, login, change PIN, forgot PIN) share the same three-step flow with the MC-SDK:

  1. Get AST client data — post a GetAstClientDataEvent to the MC-SDK and receive a GetAstClientDataResultEvent. Use the result to construct an AstClientDataInfo object.
  2. Get authorization code — call the relevant IdpSdkNativeInterface method (e.g. getAuthorizationCode). The SDK calls back your IdpSdkInteractionInterface.provideCredentials implementation to collect user credentials.
  3. Set authorization code — post a SetAuthorisationCodeEvent to the MC-SDK with the received authorization code (not required for changePin / forgotPin).

See the individual flow pages for full implementation details:
