Analytics Integration Patterns

Architecture

AnalyticsProvider Interface (Kotlin)

interface AnalyticsProvider {
    fun logEvent(name: String, params: Map<String, Any> = emptyMap())
    fun setUserProperty(name: String, value: String)
    fun setUserId(userId: String?)
    fun logScreenView(screenName: String, screenClass: String? = null)
}

AnalyticsProvider Protocol (Swift)

protocol AnalyticsProvider {
    func logEvent(_ name: String, parameters: [String: Any])
    func setUserProperty(_ value: String?, forName name: String)
    func setUserId(_ userId: String?)
    func logScreenView(screenName: String, screenClass: String?)
}

Multi-Provider Analytics Manager

class AnalyticsManager(
    private val providers: List<AnalyticsProvider>,
    private val consentManager: ConsentManager
) {
    fun logEvent(name: String, params: Map<String, Any> = emptyMap()) {
        if (!consentManager.hasAnalyticsConsent()) return
        providers.forEach { it.logEvent(name, params) }
    }

    fun setUserProperty(name: String, value: String) {
        if (!consentManager.hasAnalyticsConsent()) return
        providers.forEach { it.setUserProperty(name, value) }
    }

    fun setUserId(userId: String?) {
        providers.forEach { it.setUserId(userId) }
    }

    fun logScreenView(screenName: String, screenClass: String? = null) {
        if (!consentManager.hasAnalyticsConsent()) return
        providers.forEach { it.logScreenView(screenName, screenClass) }
    }
}

Event Data Classes

sealed class AnalyticsEvent(
    val name: String,
    val params: Map<String, Any> = emptyMap()
) {
    // E-commerce
    class ViewProduct(productId: String, category: String) : AnalyticsEvent(
        name = "view_product",
        params = mapOf("product_id" to productId, "category" to category)
    )

    class AddToCart(productId: String, price: Double, quantity: Int) : AnalyticsEvent(
        name = "add_to_cart",
        params = mapOf("product_id" to productId, "price" to price, "quantity" to quantity)
    )

    class Purchase(orderId: String, total: Double, currency: String) : AnalyticsEvent(
        name = "purchase",
        params = mapOf("order_id" to orderId, "total" to total, "currency" to currency)
    )

    // Engagement
    class Search(query: String, resultCount: Int) : AnalyticsEvent(
        name = "search",
        params = mapOf("query" to query, "result_count" to resultCount)
    )

    class ShareContent(contentType: String, itemId: String) : AnalyticsEvent(
        name = "share_content",
        params = mapOf("content_type" to contentType, "item_id" to itemId)
    )
}

// Usage
analytics.logEvent(AnalyticsEvent.ViewProduct("sku-123", "electronics"))
