Interstitial Ads

Interstitial Ads - AdManageKit v4.4.4

Overview

AdManageKit provides a complete interstitial ad stack with AdManager and the fluent InterstitialAdBuilder. Features include loading strategies, automatic retry, frequency controls, splash screen support, and Jetpack Compose utilities.

Library Version: v4.4.4

What's New

v2.8.0

• forceShowInterstitial() now respects global loading strategy
• New forceShowInterstitialAlways() for explicit force fetch
• Global interstitialAutoReload config with per-call override
• All AdManager methods use global auto-reload config as default

v2.7.0

• Smart splash screen with waitForLoading() in InterstitialAdBuilder
• New isLoading() and showOrWaitForAd() methods
• Frequency controls: everyNthTime, maxShows, minInterval

Installation

dependencies {
    implementation 'com.github.i2hammad.AdManageKit:ad-manage-kit:v4.4.4'
    implementation 'com.github.i2hammad.AdManageKit:ad-manage-kit-core:v4.4.4'
    implementation 'com.github.i2hammad.AdManageKit:ad-manage-kit-billing:v4.4.4'
    // Optional - Jetpack Compose
    implementation 'com.github.i2hammad.AdManageKit:ad-manage-kit-compose:v4.4.4'
}

Configuration

Set up in your Application.onCreate():

class MyApp : Application() {
    override fun onCreate() {
        super.onCreate()

        BillingConfig.setPurchaseProvider(BillingPurchaseProvider())

        AdManageKitConfig.apply {
            debugMode = BuildConfig.DEBUG
            defaultInterstitialInterval = 20.seconds
            autoRetryFailedAds = true
            maxRetryAttempts = 3

            // Loading strategy (v2.6.0+)
            interstitialLoadingStrategy = AdLoadingStrategy.HYBRID

            // Auto-reload after showing (v2.8.0+)
            interstitialAutoReload = true  // default: true
        }
    }
}

Since 4.2.0 you must also call MobileAds.initialize() yourself, before any ad request — the Next-Gen SDK removed the legacy SDK's silent lazy-init. This snippet covers configuration only. See Home or the sample app's MyApplication.kt for the initialization pattern.

Option 1: Direct AdManager

Basic Usage

private val adManager = AdManager.getInstance()

// Preload
fun preloadInterstitial(activity: Activity) {
    adManager.loadInterstitialAd(activity, AD_UNIT_INTERSTITIAL)
}

// Show
fun showInterstitial(activity: Activity) {
    adManager.forceShowInterstitial(activity, object : AdManagerCallback() {
        override fun onNextAction() {
            navigateNext()
        }
    })
}

Key Methods

Method	Description
loadInterstitialAd(context, adUnitId)	Preload and cache ad
loadInterstitialAdForSplash(context, unit, timeout, callback)	Splash-friendly with timeout
forceShowInterstitial(activity, callback)	Respects loading strategy (v2.8.0+)
forceShowInterstitialAlways(activity, callback)	Always force fetch (v2.8.0+)
showInterstitialIfReady(activity, callback, reloadAd)	Show only if cached
showInterstitialAdByTime(activity, callback)	Time-interval based
showInterstitialAdByCount(activity, callback, maxCount)	Count-limited
showOrWaitForAd(activity, callback, timeout, showDialog)	Smart splash (v2.7.0+)
isLoading()	Check if currently loading (v2.7.0+)
isReady()	Check if ad is cached

Loading Strategy Behavior (v2.8.0+)

forceShowInterstitial() now respects AdManageKitConfig.interstitialLoadingStrategy:

Strategy	Behavior
ON_DEMAND	Always fetch fresh ad with dialog
ONLY_CACHE	Show cached if ready, skip otherwise
HYBRID	Show cached if ready, fetch fresh otherwise
FRESH_WITH_CACHE_FALLBACK	Fetch fresh, fall back to cache if the load fails

// Set strategy
AdManageKitConfig.interstitialLoadingStrategy = AdLoadingStrategy.HYBRID

// Now respects strategy
AdManager.getInstance().forceShowInterstitial(activity, callback)

// Always force fetch (bypasses strategy)
AdManager.getInstance().forceShowInterstitialAlways(activity, callback)

Splash Screen Example

// In Application.onCreate() - start loading early
AdManager.getInstance().loadInterstitialAd(this, adUnitId)

// In SplashActivity - smart wait
AdManager.getInstance().showOrWaitForAd(
    activity = this,
    callback = object : AdManagerCallback() {
        override fun onNextAction() { startMainActivity() }
    },
    timeoutMillis = 5000,
    showDialogIfLoading = true
)

Option 2: InterstitialAdBuilder

The builder provides a fluent API with frequency controls and loading strategies.

Basic Usage

InterstitialAdBuilder.with(this)
    .adUnit("ca-app-pub-xxx/yyy")
    .show { navigateNext() }

Full Configuration

InterstitialAdBuilder.with(this)
    .adUnit("primary-unit")
    .fallback("backup-unit")
    .loadingStrategy(AdLoadingStrategy.HYBRID)
    .everyNthTime(3)           // Show every 3rd call
    .maxShows(10)              // Maximum 10 shows total
    .minIntervalSeconds(30)    // Minimum 30 seconds between
    .timeout(5000)             // 5 second timeout
    .autoReload(true)          // Auto-reload after showing
    .onAdShown { /* analytics */ }
    .onAdDismissed { /* cleanup */ }
    .onFailed { error -> /* handle */ }
    .show { navigateNext() }

Smart Splash Screen (v2.7.0+)

// In Application.onCreate()
AdManager.getInstance().loadInterstitialAd(this, adUnitId)

// In SplashActivity
InterstitialAdBuilder.with(this)
    .adUnit(adUnitId)
    .waitForLoading()     // Smart: shows cached, waits for loading, or force fetches
    .timeout(5000)        // 5 second max wait
    .show { startMainActivity() }

Behavior:

Ad State	Action
READY	Shows immediately
LOADING	Waits with timeout, shows when ready
NOT STARTED	Force fetches with dialog

Frequency Controls

// Show every 3rd time
.everyNthTime(3)

// Maximum 5 shows total
.maxShows(5)

// Minimum 30 seconds between shows
.minIntervalSeconds(30)

// Force show (bypass interval)
.force()

Auto-Reload Configuration (v2.8.0+)

// Global config
AdManageKitConfig.interstitialAutoReload = false  // Disable globally

// Per-call override
InterstitialAdBuilder.with(activity)
    .adUnit(adUnitId)
    .autoReload(true)  // Override global
    .show { next() }

Priority: Builder .autoReload() > AdManageKitConfig.interstitialAutoReload

Option 3: Jetpack Compose

@Composable
fun ContentWithInterstitial() {
    val showAd = rememberInterstitialAd(
        adUnitId = stringResource(R.string.interstitial_feed),
        preloadAd = true,
        onAdShown = { /* analytics */ },
        onAdDismissed = { navigateNext() },
        onAdFailedToLoad = { /* handle */ }
    )

    Button(onClick = showAd) {
        Text("Show Ad")
    }
}

Compose Helpers

Helper	Purpose
rememberInterstitialAd(...)	Returns lambda to show ad
InterstitialAdEffect(...)	Declarative effect with TIME/COUNT/FORCE modes
rememberInterstitialAdState(...)	Mutable state with isLoaded, loadAd(), showAd()

Best Practices

1. Configure once in Application.onCreate()
2. Use HYBRID strategy for balanced UX and coverage
3. Preload on previous screen for better fill rate
4. Use frequency controls to protect UX
5. Wire billing to skip ads for premium users
6. Enable debug mode during development

Troubleshooting

• Ad Not Loading: Check adUnitId, network, and AdMob config
• Ad Not Showing: Verify isReady() and purchase status
• Strategy Not Working: Ensure v2.8.0+ and check interstitialLoadingStrategy
