Update to RuStore SDK 2.2.0: Purchase models, dependencies and migration

In version 2.2.0 the PaymentResult models were significantly changed.

Use this manual to switch to new SDK version.

Dependency update

Kotlin

To update the dependency, increase the billingclient version in the dependencies block of your build.gradle.

dependencies {
    implementation( "ru.rustore.sdk:billingclient:2.2.0" )
}

Java

To update the dependency, increase the billingclient version in the dependencies block of your build.gradle.

dependencies {
    implementation( "ru.rustore.sdk:billingclient:2.2.0" )
}

Retrieving products list

Kotlin

The model of the receiving products list result has changed. Now the getProducts() method instantly returns the products list.

val productsUseCase: ProductsUseCase = billingClient.products
productsUseCase.getProducts(productIds = listOf("id1", "id2"))
    .addOnSuccessListener { products: List<Product> ->
        // Process success
    }
    .addOnFailureListener { throwable: Throwable ->
        // Process error
    }

Java

The model of the receiving products list result has changed. Now the getProducts() method instantly returns the products list.

ProductsUseCase productsUseCase = billingClient.getProducts();
productsUseCase.getProducts(Arrays.asList("id1" , "id2")).addOnCompleteListener( new OnCompleteListener<List<Product>>() {
    @Override
    public void onFailure( @NonNull Throwable throwable) {
        // Process error
    }
    @Override
    public void onSuccess(List<Product> products) {
        // Process success
    }
});

Purchasing product

Kotlin

The model of the purchase result has changed. Below is the updated model.

public sealed interface PaymentResult {      
    public data  class Success(
        val orderId: String?,
        val purchaseId: String,
        val productId: String,
        val invoiceId: String,
        val subscriptionToken: String? =  null ,
    ) : PaymentResult
    public data  class Cancelled(
        val purchaseId: String,
    ) : PaymentResult
    public data  class Failure(
        val purchaseId: String?,
        val invoiceId: String?,
        val orderId: String?,
        val quantity: Int?,
        val productId: String?,
        val errorCode: Int?,
    ) : PaymentResult
    public object InvalidPaymentState : PaymentResult()
}

• Success - successful purchase result.
• Failure - there was a problem during sending payment request or receiving payment status, purchase status unknown.
• Cancelled — payment request sent, although, the user closed the payment screen on their app, thus, the payment result is unknown.
• InvalidPaymentState — SDK payments error. May occur due to an incorrect return deeplink.

info

Please, note the purchase confirmation and cancellation scenarios.

Java

The model of the purchase result has changed. Below is the updated model.

interface PaymentResult {
    
    interface Success  extends PaymentResult {
        @Nullable
        public String getOrderId();
        
        public String getPurchaseId();
        
        public String getProductId();
        public String getinvoiceId();
        
        @Nullable
        public String getSubscriptionToken(); 
    }
    
    interface Failure  extends PaymentResult {
        @Nullable
        public String getPurchaseId();
        
        @Nullable
        public String getinvoiceId();
        
        @Nullable
        public String getOrderId();
        
        @Nullable
        public Integer getQuantity();
        
        @Nullable
        public String getProductId();
        @Nullable
        public Integer getErrorCode();
    }
    interface Cancelled  extends PaymentResult {
        public String getPurchaseId();
    }          
    interface InvalidPaymentState  extends PaymentResult {}
}

• Success - successful purchase result.
• Failure - there was a problem during sending payment request or receiving payment status, purchase status unknown.
• Cancelled — payment request sent, although, the user closed the payment screen on their app, thus, the payment result is unknown.
• InvalidPaymentState — SDK payments error. May occur due to an incorrect return deeplink.

Please, note the purchase confirmation and cancellation scenarios.

### Confirm (consume) purchase

Kotlin

The state model of the purchase confirmation result has changed. Now confirmation may complete either successfully or with an error.

val purchasesUseCase: PurchasesUseCase = billingClient.purchases
purchasesUseCase.confirmPurchase(purchaseId =  "purchaseId" , developerPayload =  null )
    .addOnSuccessListener {
        // Process success
    }.addOnFailureListener { throwable: Throwable ->
        // Process error
    }

Java

The state model of the purchase confirmation result has changed. Now confirmation may complete either successfully or with an error.

PurchasesUseCase purchasesUseCase = billingClient.getPurchases();
purchasesUseCase.confirmPurchase("purchaseId", "developerPayload").addOnCompleteListener( new OnCompleteListener<Unit>() {
    @Override
    public void onFailure( @NonNull Throwable throwable) {
        // Process error
    }
    @Override
    public void onSuccess(Unit result) {
        // Process success
    }
});

Purchase cancellation

Kotlin

The model of the purchase cancellation result has changed. Now cancellation may end either successfully or with an error.

val purchasesUseCase: PurchasesUseCase = billingClient.purchases
purchasesUseCase.deletePurchase(purchaseId =  "purchaseId" )
    .addOnSuccessListener {
        // Process success
    }.addOnFailureListener { throwable: Throwable ->
        // Process error
    }

Java

The model of the purchase cancellation result has changed. Now cancellation may end either successfully or with an error.

PurchasesUseCase purchasesUseCase = billingClient.getPurchases();
purchasesUseCase.deletePurchase("purchaseId").addOnCompleteListener( new OnCompleteListener<Unit>() {
    @Override
    public void onFailure( @NonNull Throwable throwable) {
        // Process error
    }
    @Override
    public void onSuccess(Unit result) {
        // Process success
    }
});

Purchase confirmation and cancellation scenario

Due to the change of the product purchase model result, the business logic of the purchase confirmation and cancellation was also changed.

Use the deletePurchase method in the following cases:

• the getPurchases method returned a purchase with one of the following statuses:

  • PurchaseState.CREATED;
  • PurchaseState.INVOICE_CREATED;

• the purchaseProduct method returned:

  • PaymentResult.Cancelled;
  • PaymentResult.Failure.

Use the (confirmPurchase) method if the (getPurchases) method returned a CONSUMABLE purchase with the PurchaseState.PAID status.
