RxAds

RxJava wrapper for Play Services Ads. The library currently supports loading Native Ads (Native Content, Native Install, Native Custom Template) and Interstitial Ads.

Philosophy

RxAds' only aim is to make ad loading reactive. The library does not provide ways to convert clicks to ads as streams or to provide various streams for it's varied callback.

However, Play Services Ads is a big SDK and it's not the aim of this library to replicate all functionality. Hence, RxAds builds on existing functionality and allows you to load ads using reactive streams.

For example:

AdLoader adLoader = new AdLoader.Builder(context, "ca-app-pub-3940256099942544/2247696110")
    .forContentAd(new OnContentAdLoadedListener() {
        @Override
        public void onContentAdLoaded(NativeContentAd contentAd) {
            // Show the content ad.
        }
    })
    .withAdListener(new AdListener() {
        @Override
        public void onAdFailedToLoad(int errorCode) {
            // Handle the failure by logging, altering the UI, and so on.
        }
    })
    .withNativeAdOptions(new NativeAdOptions.Builder()
            // Methods in the NativeAdOptions.Builder class can be
            // used here to specify individual options settings.
            .build())
    .build();

adLoader.loadAd(new PublisherAdRequest.Builder().build());

can easily become

Disposable disposable = new RxAdLoader(context, "ad_unit_id") // Initialize same as AdLoader.Builder
                // Chain any other options from Play Services Ads
                .withNativeAdOptions(new NativeAdOptions.Builder().build())
                .loadNativeContentAd(new AdRequest.Builder().build()) // Load ad
                .subscribe(...); 

You can keep chaining your custom listeners and just call loadAd(args...) when you're done.

Usage

Native Install Ad

RxAdLoader adLoader = new RxAdLoader(this, "ad_unit_id");
adLoader.loadInstallAd(new AdRequest.Builder().build())
        .subscribeWith(new DisposableSingleObserver<NativeAppInstallAd>() {
            @Override
            public void onSuccess(NativeAppInstallAd nativeAppInstallAd) {
                // Set to view
            }

            @Override
            public void onError(Throwable e) {
                // Handle error
            }
         });

Native Content Ad

RxAdLoader adLoader = new RxAdLoader(this, "ad_unit_id");
adLoader.loadNativeContentAd(new AdRequest.Builder().build())
        .subscribeWith(new DisposableSingleObserver<NativeContentAd>() {
            @Override
            public void onSuccess(NativeContentAd nativeContentAd) {
                // Set to view                
            }

            @Override
            public void onError(Throwable e) {
                // Handle error
            }
        });

Interstitial Ad

Java

RxInterstitialAd ad = new RxInterstitialAd(this);
ad.loadAd("ad_unit_id", new AdRequest.Builder().build())
        .subscribeWith(new DisposableSingleObserver<InterstitialAd>() {
            @Override
            public void onSuccess(InterstitialAd interstitialAd) {
                interstitialAd.show();
            }

            @Override
            public void onError(Throwable e) {

            }
        });

Kotlin Extensions

The library is written in Kotlin and it has Kotlin extensions for most APIs

Interstitial Ad

val ad = InterstitialAd(this)
ad.adUnitId = "ad_unit_id"
ad.asSingle(AdRequest.Builder().build())
        .subscribe({ interstitialAd -> 
            interstitialAd.show()
        }, { throwable -> 
            // Handle error
        })

Native Install Ad

AdLoader.Builder(this, "ad_unit_id")
                .loadInstallAd(AdRequest.Builder().build())
                .subscribe({ installAd ->
                    // Set to view
                    }, { e ->
                    // Handle error
                })

Error Handling

If you've used the Play Services Ads SDK, the error handling leaves much to be desired. It returns an error code, which you must then search for. RxAds makes it easy and generates a human readable error message actually telling you what happened.

Download

implementation 'com.shaishavgandhi.rxads:rxads:x.y.z'

Before Play Services 15.0, projects importing multiple Play Services library had to have the same version number to avoid runtime crashes. If you haven't yet migrated to 15.0 or above, you can compile your project by excluding com.google.android.gmsfrom this library as such:

implementation ('com.shaishavgandhi.rxads:rxads:x.y.z') {
    exclude group: 'com.google.android.gms'
}

After the Play Services 15 release, this is not a problem. RxAds will have a corresponding release for every Play Services Ads release to give you the latest functionality.

Snapshots of the development version are available in Sonatype's snapshots repository.
