To seamlessly integrate AdMob into your Jetpack Compose Android app, you need to include the necessary dependencies in your project. Below are the code examples that illustrate how to add these dependencies to your AndroidManifest.xml and build.gradle files.

AndroidManifest.xml

<manifest xmlns:android="https://schemas.android.com/apk/res/android"
    package="your.package.name">

    <!-- Add the following permission for AdMob -->
    <uses-permission android:name="com.google.android.gms.permission.AD_ID"/>

    <application>
        <!-- Add your AdMob application ID as a meta-data tag -->
        <meta-data
            android:name="com.google.android.gms.ads.APPLICATION_ID"
            android:value="@string/ADMOB_ID"/>
    </application>
</manifest>        

Make sure to replace "your.package.name" with the actual package name of your Android app.

build.gradle (app-level)

android {
    // ... (other configurations)
    buildTypes {
        debug {
            // Set default AdMob ID and ad unit IDs for the debug build
            resValue("string", "ADMOB_ID", "\"ca-app-pub-3940256099942544~3347511713\"")
            buildConfigField("String", "BANNER_AD", "\"ca-app-pub-3940256099942544/6300978111\"")
            buildConfigField("String", "REWARD_AD", "\"ca-app-pub-3940256099942544/5224354917\"")
        }

        release {
            // Use AdMob ID and ad unit IDs from gradle.properties for the release build
            resValue("string", "ADMOB_ID", gradleLocalProperties(rootDir).getProperty("ADMOB_ID"))
            buildConfigField("String", "BANNER_AD", gradleLocalProperties(rootDir).getProperty("BANNER_AD"))
            buildConfigField("String", "REWARD_AD", gradleLocalProperties(rootDir).getProperty("REWARD_AD"))

        }
    }
}

dependencies {
    // Add the AdMob SDK dependency
    implementation "com.google.android.gms:play-services-ads:22.5.0"
}        

In the above code, ensure that you replace the default AdMob IDs in the debug build with your actual AdMob application ID, banner ad unit ID, and reward ad unit ID. The release build will automatically fetch these values from the gradle.properties file.

By including these dependencies in your project, you pave the way for AdMob integration in your Jetpack Compose Android app. The AdMob SDK version used in this example is 22.5.0, but you may want to check for the latest version available on the official Google Maven Repository

Banner Ads in Jetpack Compose: Navigating Adaptive Banner Challenges

Banner ads serve as a fundamental component in the monetization strategy of many Android applications. However, as of the latest information available, AdMob's full support for Jetpack Compose, particularly in the context of adaptive banners, remains a work in progress. Nonetheless, developers can still integrate banner ads seamlessly into their Jetpack Compose applications using traditional methods.

Jetpack Compose Implementation

Here is an example of integrating a banner ad in Jetpack Compose:

@Composable
fun AdmobBanner(modifier: Modifier = Modifier) {
    AndroidView(
        modifier = modifier,
        factory = { context ->
            AdView(context).apply {
                setAdSize(AdSize.BANNER)
                adUnitId = BuildConfig.BANNER_AD
                loadAd(AdRequest.Builder().build())
            }
        }
    )
}        

In this Composable function, an AdView is created with a fixed AdSize.BANNER and loaded with the ad unit ID specified in the BuildConfig.

Adaptive Banner Challenges:

Unfortunately, when it comes to adaptive banners—dynamic banners that adjust their size based on the available screen space—AdMob's full compatibility with Jetpack Compose faces limitations. The code example you provided for adaptive banners using data binding is not directly applicable to Jetpack Compose.

<FrameLayout
    android:id="@+id/adViewContainer"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"/>        

    fun setupBanner(adContainerView: FrameLayout) {
        adView = AdView(requireContext())
        adContainerView.addView(adView)
        adContainerView.viewTreeObserver.addOnGlobalLayoutListener {
            if (!initialLayoutComplete) {
                initialLayoutComplete = true
                loadBanner(adContainerView)
            }
        }
    }

    private fun loadBanner(adContainerView: FrameLayout) {
        adView.adUnitId = BuildConfig.AD_MOB_BANNER
        adView.setAdSize(getAdSize(adContainerView))
        adView.loadAd(AdRequest.Builder().build())
    }

    private fun getAdSize(adContainerView: FrameLayout): AdSize {
        val width = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
            val windowMetrics = requireActivity().windowManager.currentWindowMetrics
            windowMetrics.bounds.width().toFloat()
        } else {
            val displayMetrics = DisplayMetrics()
            requireActivity().windowManager.defaultDisplay.getMetrics(displayMetrics)
            displayMetrics.widthPixels.toFloat()
        }

        var adWidthPixels = adContainerView.width.toFloat()

        if (adWidthPixels == 0f) {
            adWidthPixels = width
        }

        val density = resources.displayMetrics.density
        val adWidth = (adWidthPixels / density).toInt()

        return AdSize.getCurrentOrientationAnchoredAdaptiveBannerAdSize(requireContext(), adWidth)
    }        

The adaptive banner example involves calculating the available width dynamically, which can be challenging to replicate directly in Jetpack Compose.

Recommendations

While waiting for official support, consider using fixed-size banners or alternative ad formats that align with your app's design. Stay informed about updates from both the Jetpack Compose and AdMob communities, as improvements and compatibility enhancements are likely to be introduced over time.

As of now, leveraging traditional banner ad integration, as demonstrated in the Jetpack Compose example, remains a practical approach until full support for adaptive banners is realized. Keep an eye on official documentation and release notes for any advancements in Jetpack Compose and AdMob integration.

Conclusion

Despite the great promise, it is critical to recognize the existing limits, especially in the field of adaptable banners. AdMob's full support for Jetpack Compose, particularly with dynamically modifying ad sizes, is still in the works. Developers that want to create adaptive ad experiences may face difficulties, but they may still employ classic banner ad systems to strike a compromise between user experience and profitability.

As you begin your quest to monetize your Jetpack Compose Android app, keep in mind that effective integration requires more than simply displaying advertising; it also requires carefully arranging them to enhance rather than interrupt the user experience. Experiment with various ad unit kinds, positions, and frequency to discover the sweet spot that corresponds to your app's content and user engagement plan.

Keep an eye out for updates from the Jetpack Compose and AdMob ecosystems, as continuing improvements and optimizations are likely to improve the integration experience. Collaborate with the dynamic developer communities, exchange insights, and help shape the future of Android app development.
