Class Index com.ikame.android.sdk.billing.IKBilling

Verify Google Play Services for In-App Purchases

This function determines if the Google Play Billing (In-App Billing) service is available on the device. It is essential for ensuring that the device can handle in-app purchases before attempting any IAP operations.

  fun isIabServiceAvailable(context: Context?): Boolean
Example 
  if (!ikBilling.isIabServiceAvailable(this)) {
    // Google Play Services is not available
}
  
  if (!ikBilling.isIabServiceAvailable(this)) {
    // Google Play Services is not available
}

Verify Previous User Purchases

Used in cases where the user changes phones or has made a purchase before.

  fun reCheckIAP(
  listener: IKBillingListener?,
  hasDelay: Boolean = false
)

Parameters:

  • listener: The IKBillingListener interface is designed to handle the billing process callbacks within an application. It provides methods for responding to the outcomes of billing actions.

    • onBillingSuccess(): Called when the billing process completes successfully.

    • onBillingFail(): Called when the billing process fails.

  • hasDelay: This optional parameter determines whether the re-check process should be delayed. If set to true, the function will wait a specified time before starting the re-check (useful in some UI or background task scenarios). The default value is false, meaning no delay.

Example 
  ikBilling.reCheckIAP(object : IKBillingListener {
    override fun onBillingSuccess() {
    }

    override fun onBillingFail() {
    }
}, false)
  
  ikBilling.reCheckIAP(new IKBillingListener() {
    @Override
    public void onBillingSuccess() {

    }

    @Override
    public void onBillingFail() {

    }
}, false);

Verify User’s In-App and Subscription Purchases 

  fun isUserIAPAvailableAsync(): Boolean
Example 
  suspend fun isUserIAPAvailableAsync() {
    val hasPurchased = IKUtils.isUserIAPAvailableAsync()

    if (hasPurchased) {
        // User has purchased at least one package
    } else {
        // No purchases found for the user
    }
}
  
  //Kotlin wrapper:
import kotlinx.coroutines.runBlocking;

public fun isUserIAPAvailableBlocking(): Boolean = runBlocking {
    IKUtils.isUserIAPAvailableAsync()
}
//Java call:
boolean isAvailable = YourKotlinClass.INSTANCE.isUserIAPAvailableBlocking();

Verify User’s Purchase of a Specific Package

To check if the user has purchased a specific in-app purchase or subscription package, use the isProductIAPAsync() method, which takes a product (of type SdkIapPackageDto) as an argument.

  fun isProductIAPAsync(product: SdkIapPackageDto): Boolean
Example 
  suspend fun isProductIAPAsync() {
    val specificProduct = SdkIapPackageDto("android.test.purchased", IKProductType.SUBS.value)
    val isPurchased = IKUtils.isProductIAPAsync(specificProduct)

    if (isPurchased) {
        // The specific product has been purchased
    } else {
        // The product has not been purchased
    }
}
  
  //Kotlin wrapper:
import kotlinx.coroutines.runBlocking;

public fun isProductIAPAsync(specificProduct : SdkIapPackageDto): Boolean = runBlocking {
        IKUtils.isProductIAPAsync(specificProduct)
    }
//Java call:
SdkIapPackageDto specificProduct = new SdkIapPackageDto("android.test.purchased", IKProductType.SUBS.getValue());
boolean isAvailable = YourKotlinClass.INSTANCE.isProductIAPAsync(specificProduct);
