Billing Integration

Billing Integration

AdManageKit provides a comprehensive billing integration module (admanagekit-billing) that simplifies Google Play Billing Library v8 implementation.

Quick Start

1. Add Dependency

implementation 'com.github.i2hammad.AdManageKit:ad-manage-kit-billing:v2.9.0'
implementation 'com.github.i2hammad.AdManageKit:ad-manage-kit-core:v2.9.0'

2. Define Products

val products = listOf(
    // Consumable (coins, gems)
    PurchaseItem("coins_100", TYPE_IAP.PURCHASE, PurchaseCategory.CONSUMABLE),

    // Lifetime premium (disables ads)
    PurchaseItem("lifetime", TYPE_IAP.PURCHASE, PurchaseCategory.LIFETIME_PREMIUM),

    // Remove ads only
    PurchaseItem("remove_ads", TYPE_IAP.PURCHASE, PurchaseCategory.REMOVE_ADS),

    // Subscription with trial
    PurchaseItem("premium_monthly", "free_trial", TYPE_IAP.SUBSCRIPTION)
)

3. Initialize

class MyApp : Application() {
    override fun onCreate() {
        super.onCreate()
        AppPurchase.getInstance().initBilling(this, products)
    }
}

4. Make Purchases

// In-app purchase
AppPurchase.getInstance().purchase(activity, "remove_ads")

// Subscription
AppPurchase.getInstance().subscribe(activity, "premium_monthly")

5. Check Purchase Status

if (AppPurchase.getInstance().isPurchased()) {
    // User has premium (subscription, lifetime, or remove_ads)
}
