Load and Show Plan

This section explains how to load and display a plan using the SDK.

Overview

• A plan is managed by a presenter created with ExpoFpPlan.createPlanPresenter(...).
• The presenter provides a WebView via getView().
  • In a View-based UI, you add this WebView into your layout.
  • In Jetpack Compose, you use AndroidView to host the WebView.
• You can optionally provide additional parameters, a location provider, and a message listener.

Step 1. Initialize the SDK

Call ExpoFpPlan.initialize(context) once, usually in Application or the first Activity.

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    ExpoFpPlan.initialize(this)
}

Step 2. Minimal Example (View-based)

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        ExpoFpPlan.initialize(this)

        val presenter = ExpoFpPlan.createPlanPresenter(
            planLink = ExpoFpLinkType.RawLink("https://demo.expofp.com")
        )

        val expoView = ExpoFpView(this).apply {
            attachPresenter(presenter)
        }

        setContentView(expoView)
    }
}

Step 3. Minimal Example (Jetpack Compose)

class MainActivity : ComponentActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        ExpoFpPlan.initialize(this)

        val presenter = ExpoFpPlan.createPlanPresenter(
            planLink = ExpoFpLinkType.RawLink("https://demo.expofp.com")
        )

        setContent {
            AndroidView(factory = { presenter.getView() })
        }
    }
}

Step 4. Advanced Initialization

You can customize the presenter by passing additional parameters, a location provider, and a message listener.

val expoKey = "YourExpoKey"
val additionalParams = listOf(URLQueryItem("noOverlay", "true"))
val locationProvider: IExpoFpLocationProvider = YourLocationProvider()
val messageListener: IExpoFpPlanMessageListener = YourMessageListener()

val presenter = ExpoFpPlan.createPlanPresenter(
    planLink = ExpoFpLinkType.ExpoKey(expoKey),
    additionalParams = additionalParams,
    locationProvider = locationProvider,
    messageListener = messageListener
)
