Hiển thị paywall được tạo bằng Paywall Builder ở chế độ Observer trên Android SDK

val observerModeHandler =
 AdaptyUiObserverModeHandler { product, paywall, paywallView, onStartPurchase, onFinishPurchase ->
    onStartPurchase()
    yourBillingClient.makePurchase(
        product,
        onSuccess = { purchase ->
            onFinishPurchase()
            //handle success
        },
        onError = {
            onFinishPurchase()
            //handle error
        },
        onCancel = {
            onFinishPurchase()
            //handle cancel
        }
    )
}

AdaptyUiObserverModeHandler observerModeHandler = (product, paywall, paywallView, onStartPurchase, onFinishPurchase) -> {
    onStartPurchase.invoke();
    yourBillingClient.makePurchase(
        product,
        purchase -> {
            onFinishPurchase.invoke();
            //handle success
        },
        error -> {
            onFinishPurchase.invoke();
            //handle error
        },
        () -> { //cancellation
            onFinishPurchase.invoke();
            //handle cancel
        }
    );
};

val observerModeHandler = object : AdaptyUiObserverModeHandler {
    // onPurchaseInitiated implementation (see above)

    override fun getRestoreHandler() =
        AdaptyUiObserverModeHandler.RestoreHandler { onStartRestore, onFinishRestore ->
            onStartRestore()
            yourBillingClient.restorePurchases(

                    //handle successful restore
                },
                onError = {
                    onFinishRestore()
                    //handle error
                }
            )
        }
}

AdaptyUiObserverModeHandler observerModeHandler = new AdaptyUiObserverModeHandler() {
    // onPurchaseInitiated implementation (see above)

    @Override
    public RestoreHandler getRestoreHandler() {
        return (onStartRestore, onFinishRestore) -> {
            onStartRestore.invoke();
            yourBillingClient.restorePurchases(
                restoredPurchases -> {
                    onFinishRestore.invoke();
                    //handle successful restore
                },
                error -> {
                    onFinishRestore.invoke();
                    //handle error
                }
            );
        };
    }
};

Để làm điều đó, gọi phương thức AdaptyUI.getPaywallView() hoặc tạo AdaptyPaywallView trực tiếp:

   val paywallView = AdaptyUI.getPaywallView(
       activity,
       viewConfiguration,
       products,
       eventListener,
       personalizedOfferResolver,
       tagResolver,
       timerResolver,
       observerModeHandler, 
   )

   val paywallView =
        AdaptyPaywallView(activity) // or retrieve it from xml
   ...
   with(paywallView) {
       showPaywall(
           viewConfiguration,
           products,
					 eventListener,
           personalizedOfferResolver,
           tagResolver,
           timerResolver,
					 observerModeHandler,
       )
   }

AdaptyPaywallView paywallView = AdaptyUI.getPaywallView(
        activity,
        viewConfiguration,
        products,
        eventListener,
        personalizedOfferResolver,
        tagResolver,
        timerResolver,
        observerModeHandler
);

AdaptyPaywallView paywallView =
  new AdaptyPaywallView(activity); //add to the view hierarchy if needed, or you receive it from xml
...
paywallView.showPaywall(viewConfiguration, products, eventListener, personalizedOfferResolver, tagResolver, timerResolver, observerModeHandler);

<com.adapty.ui.AdaptyPaywallView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

Sau khi view được tạo thành công, bạn có thể thêm nó vào view hierarchy và hiển thị.

Để làm điều đó, sử dụng hàm composable sau:

AdaptyPaywallScreen(
    viewConfiguration,
    products,
    eventListener,
    personalizedOfferResolver,
    tagResolver,
    timerResolver,
)

val observerModeHandler =
AdaptyUiObserverModeHandler { product, paywall, paywallView, onStartPurchase, onFinishPurchase ->
    onStartPurchase()
    yourBillingClient.makePurchase(
        product,
        onSuccess = { purchase ->
            onFinishPurchase()
            //handle success
        },
        onError = {
            onFinishPurchase()
            //handle error
        },
        onCancel = {
            onFinishPurchase()
            //handle cancel
        }
    )
}

AdaptyUiObserverModeHandler observerModeHandler = (product, paywall, paywallView, onStartPurchase, onFinishPurchase) -> {
    onStartPurchase.invoke();
    yourBillingClient.makePurchase(
        product,
        purchase -> {
            onFinishPurchase.invoke();
            //handle success
        },
        error -> {
            onFinishPurchase.invoke();
            //handle error
        },
        () -> { //cancellation
            onFinishPurchase.invoke();
            //handle cancel
        }
    );
};

val paywallView = AdaptyUI.getPaywallView(
    activity,
    viewConfiguration,
    products,
    AdaptyPaywallInsets.of(topInset, bottomInset),
    eventListener,
    personalizedOfferResolver,
    tagResolver,
    observerModeHandler,
)

//======= OR =======

val paywallView =
     AdaptyPaywallView(activity) // or retrieve it from xml
...
with(paywallView) {
    setEventListener(eventListener)
    setObserverModeHandler(observerModeHandler)
    showPaywall(
        viewConfiguration,
        products,
        AdaptyPaywallInsets.of(topInset, bottomInset),
        personalizedOfferResolver,
        tagResolver,
    )
}

AdaptyPaywallView paywallView = AdaptyUI.getPaywallView(

        viewConfiguration,
        products,
        AdaptyPaywallInsets.of(topInset, bottomInset),

        observerModeHandler
