Handle errors in Kotlin Multiplatform SDK

This page covers error handling in the Adapty Kotlin Multiplatform SDK.

Error handling basics​

All Adapty SDK methods return results that can be either success or error. Always handle both cases:

Adapty.getProfile { result ->
    when (result) {
        is AdaptyResult.Success -> {
            val profile = result.value
            // Handle success
        }
        is AdaptyResult.Error -> {
            val error = result.error
            // Handle error
            Log.e("Adapty", "Error: ${error.message}")
        }
    }
}

Common error codes​

Error CodeDescriptionSolution
1000No product IDs foundCheck product configuration in dashboard
1001Network errorCheck internet connection
1002Invalid SDK keyVerify your SDK key
1003Can't make paymentsDevice doesn't support payments
1004Product not availableProduct not configured in store

Handle specific errors​

Network errors​

Adapty.getPaywall("main") { result ->
    when (result) {
        is AdaptyResult.Success -> {
            val paywall = result.value
            // Use paywall
        }
        is AdaptyResult.Error -> {
            val error = result.error
            when (error.code) {
                1001 -> {
                    // Network error - show offline message
                    showOfflineMessage()
                }
                else -> {
                    // Other errors
                    showErrorMessage(error.message)
                }
            }
        }
    }
}

Purchase errors​

product.makePurchase { result ->
    when (result) {
        is AdaptyResult.Success -> {
            val purchase = result.value
            // Purchase successful
            showSuccessMessage()
        }
        is AdaptyResult.Error -> {
            val error = result.error
            when (error.code) {
                1003 -> {
                    // Can't make payments
                    showPaymentNotAvailableMessage()
                }
                1004 -> {
                    // Product not available
                    showProductNotAvailableMessage()
                }
                else -> {
                    // Other purchase errors
                    showPurchaseErrorMessage(error.message)
                }
            }
        }
    }
}

Error recovery strategies​

Retry on network errors​

fun getPaywallWithRetry(placementId: String, maxRetries: Int = 3) {
    var retryCount = 0
    
    fun attemptGetPaywall() {
        Adapty.getPaywall(placementId) { result ->
            when (result) {
                is AdaptyResult.Success -> {
                    val paywall = result.value
                    // Use paywall
                }
                is AdaptyResult.Error -> {
                    val error = result.error
                    if (error.code == 1001 && retryCount < maxRetries) {
                        // Network error - retry
                        retryCount++
                        Handler(Looper.getMainLooper()).postDelayed({
                            attemptGetPaywall()
                        }, 1000 * retryCount) // Exponential backoff
                    } else {
                        // Max retries reached or other error
                        showErrorMessage(error.message)
                    }
                }
            }
        }
    }
    
    attemptGetPaywall()
}

Fallback to cached data​

class PaywallManager {
    private var cachedPaywall: AdaptyPaywall? = null
    
    fun getPaywall(placementId: String) {
        Adapty.getPaywall(placementId) { result ->
            when (result) {
                is AdaptyResult.Success -> {
                    val paywall = result.value
                    cachedPaywall = paywall
                    showPaywall(paywall)
                }
                is AdaptyResult.Error -> {
                    val error = result.error
                    if (error.code == 1001 && cachedPaywall != null) {
                        // Network error - use cached paywall
                        showPaywall(cachedPaywall!!)
                        showOfflineIndicator()
                    } else {
                        // No cache available or other error
                        showErrorMessage(error.message)
                    }
                }
            }
        }
    }
}
