InterstitialAd and java.lang.RuntimeException: android.os.TransactionTooLargeException: data parcel size 534336 bytes

Question

I am trying to implement InterstitialAd in Jetpack Compose. This is my AdsHelpder.kt class:

class AdsHelper(private val context: Context) : FullScreenContentCallback() {

    private var onAdDismissed: (() -> Unit)? = null
    private var interstitialAd: InterstitialAd? = null
    private val adRequest = AdRequest.Builder().build()

    fun onDestroy() {
        interstitialAd?.fullScreenContentCallback = null
        interstitialAd = null
    }

    
    fun onLoadInterstitialAd(canLoad: Boolean) {
        val id = context.onString(R.string.interstitial_ad_id)
        if (canLoad) {
            InterstitialAd.load(context, id, adRequest, object : InterstitialAdLoadCallback() {
                override fun onAdLoaded(p0: InterstitialAd) {
                    interstitialAd = p0
                }

                override fun onAdFailedToLoad(p0: LoadAdError) {
                    interstitialAd = null
                }
            })
        }
    }

    override fun onAdDismissedFullScreenContent() {
        interstitialAd = null
        onAdDismissed?.invoke()
    }

    fun onShowInterstitialAd(onAdDismissed: () -> Unit) {
        interstitialAd?.apply {
            show(context.onMainActivity())
            fullScreenContentCallback = this@AdsHelper
        }
        this.onAdDismissed = onAdDismissed
    }

    override fun onAdFailedToShowFullScreenContent(e: AdError) {
        interstitialAd = null
    }
}

Since I need to show the InterstitialAd in several screens, I think this implementation way looks optimal for MainActivity.kt:

class MainActivity : ComponentActivity() {

    private lateinit var data: Data
    private var adsHelper: AdsHelper? = null

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        data = ViewModelProvider(this)[Data::class.java]

        adsHelper = AdsHelper(this)

        setContent {
            AppTheme {

                val controller = rememberAnimatedNavController()

                controller.addOnDestinationChangedListener { _, route, _ ->
                   adsHelper?.onLoadInterstitialAd(route != HOME)
                }

                LaunchedEffect(data.interstitial) {
                    when {
                        data.interstitial -> adsHelper?.onShowInterstitialAd {
                            data.interstitial = false
                        }
                    }
                }

                Column {
                    Scaffold(
                        Modifier.weight(1f)
                    ) { 
                       NavGraph(controller, data)
                    }                
                }
            }
        }
    }

    override fun onDestroy() {
        adsHelper?.onDestroy()
        super.onDestroy()
    }
}

Here the Data.kt:

class Data(app: Application) : AndroidViewModel(app) {
    var interstitial by mutableStateOf(false)
}

I could avoide these lines in the MainActivity.kt

...
controller.addOnDestinationChangedListener { _, route, _ ->
    adsHelper?.onLoadInterstitialAd(route != HOME)
}
...

and directly call adsHelper?.onLoadInterstitialAd(true), but it causes endless logs:

...

furthermore, while generating those logs and especially showing up a InterstitialAd (when data.interstitial = true), the the app slows down/freezes.

That's why I decided to load the InterstitialAd only in target screens, in this case all screens beside the HOME. But this does not solve the problem and the logs are kept loading endless.

Moreover, according to Crashlytics and App Quality Insights there occurs a TransactionTooLargeException.

But the app does not crash, only freezes until data.interstitial = false. After that the app runs ok.

Obviously, loading and showing up the InterstitialAd consumes a lot of resources/memory, especially, if there is a video ad.

I recently started working with Jetpack Compose and many things are new to me. Therefore, my implementation could be wrong and not really optimal. What might be wrong here?

Answer 1

Firstly, I would recommend that you consider separating your concerns in your classes.

---

AdComponents.kt

class holding your InterstitialAd and AdaptiveBannerAd implementation.

@Composable
fun AdMobBanner() {
    val currentWidth = LocalConfiguration.current.screenWidthDp
    AndroidView(factory = { context ->
        AdView(context).apply {
            setAdSize(AdSize.getCurrentOrientationAnchoredAdaptiveBannerAdSize(context, currentWidth))
            adUnitId = context.getString(R.string.test_app_banner_id)
            loadAd(AdRequest.Builder().build())
        }
    })
}

// Remove @Inject annotation if you're not using Hilt
class AdMobInterstitial @Inject constructor(
    private val context : Context
){
    var mInterstitialAd : InterstitialAd? = null

    fun loadAd() {
        val adUnitId = context.getString(R.string.test_app_interstitial_id)
        val adRequest = AdRequest.Builder().build()

        InterstitialAd.load(
            context, adUnitId, adRequest,
            object : InterstitialAdLoadCallback() {
                override fun onAdLoaded(ad: InterstitialAd) {
                    mInterstitialAd = ad
                }

                override fun onAdFailedToLoad(error: LoadAdError) {
                    mInterstitialAd = null
                }
            }
        )
    }

    fun showAd(activity: Activity) {
        mInterstitialAd?.let {
            it.fullScreenContentCallback = object : FullScreenContentCallback() {
                override fun onAdDismissedFullScreenContent() {
                    super.onAdDismissedFullScreenContent()
                    mInterstitialAd = null
                    loadAd()
                    logger("Ad Dismissed")
                }

                override fun onAdShowedFullScreenContent() {
                    super.onAdShowedFullScreenContent()
                    logger("Ad Showed Full Screen Content")
                }

                override fun onAdFailedToShowFullScreenContent(p0: AdError) {
                    super.onAdFailedToShowFullScreenContent(p0)
                    mInterstitialAd = null
                    logger("Ad failed to show fullScreenContent")
                }
            }
            it.show(activity)
        } ?: loadAd()
    }

    private fun logger(msg : String) {
        Log.e("AdComponents",msg)
    }
}

Feel free to change the above Interstitial class according to your need.

I suggest creating a separate NavGraph class to contain your composable.

AppNavGraph

@OptIn(ExperimentalAnimationApi::class)
@Composable
fun AppNavGraph(showAd: () -> Unit) {
    val navController = rememberAnimatedNavController()
    
    AnimatedNavHost(
        navController = navController,
        startDestination = Screens.HomeScreen.name
    ) {
        composable(
            route = "Your screen name",
            enterTransition = { slideInHorizontally (tween(400)) { 1000 } },
            exitTransition = { slideOutHorizontally (tween(400)) { -1000 } },
            popEnterTransition = { slideInHorizontally (tween(400)) { -1000 } },
            popExitTransition = { slideOutHorizontally (tween(400)) { 1000 } },
        ) {
            LaunchedEffect(key1 = Unit) {
                it.whenCreated { showAd() }
            }
            // call your screen composable here
        }
    }
}

MainActivity

with Hilt Dependency Injection.

@AndroidEntryPoint
class MainActivity : ComponentActivity() {

    @Inject lateinit var adMobInterstitial : AdMobInterstitial
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        adMobInterstitial.loadAd()
        setContent {
            AppTheme {
                // A surface container using the 'background' color from the theme
                Surface(
                    modifier = Modifier.fillMaxSize(),
                    color = MaterialTheme.colorScheme.background
                ) {
                    AppNavigation {
                        adMobInterstitial.showAd(this)
                    }
                }
            }
        }
    }
}

MainActivity

Without Dependency Injection.

class MainActivity : ComponentActivity() {

    private lateinit var adMobInterstitial : AdMobInterstitial
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        adMobInterstitial = AdMobInterstitial(context = this)
        adMobInterstitial.loadAd()
        setContent {
            AppTheme {
                // A surface container using the 'background' color from the theme
                Surface(
                    modifier = Modifier.fillMaxSize(),
                    color = MaterialTheme.colorScheme.background
                ) {
                    AppNavigation {
                        adMobInterstitial.showAd(this)
                    }
                }
            }
        }
    }
}
