Firebase Integration

1. Prerequisites

• Ensure that both the TradPlus SDK and Firebase SDK are correctly integrated into your project.
• Initialize the SDKs and integrate at least one type of advertisement.
• The TradPlus SDK supports real-time retrieval of ad revenue. Developers can log the Google Analytics ad_impression event by listening to the impression callback to obtain the eCPM value of the currently displayed ad.

2. Code Implementation

Version Information:

Version	Description
V9.5.0.1+	Optimized; can be called directly without synchronously setting setAdListener
V8.8.0.1+	Provides a global impression callback API. Synchronous execution requires calling setAdListener of the corresponding ad type to receive GlobalImpressionListener monitoring.
V8.8.0.1 and below	Get ad revenue through the ad type's onAdImpression

Implementation Example:

TradPlusSdk.setGlobalImpressionListener(new GlobalImpressionManager.GlobalImpressionListener() {
    @Override
    public void onImpressionSuccess(TPAdInfo tpAdInfo) {
        FirebaseAnalytics mFirebaseAnalytics = FirebaseAnalytics.getInstance(this);
        if (tpAdInfo != null) {
            Bundle bundle = new Bundle();
            bundle.putString(FirebaseAnalytics.Param.AD_PLATFORM, "TradPlus");
            bundle.putString(FirebaseAnalytics.Param.AD_SOURCE, tpAdInfo.adSourceName);
            bundle.putString(FirebaseAnalytics.Param.CURRENCY, "USD");
            bundle.putDouble(FirebaseAnalytics.Param.VALUE, tpAdInfo.ecpm / 1000.0);
            mFirebaseAnalytics.logEvent(FirebaseAnalytics.Event.AD_IMPRESSION, bundle);
        }
    }
});

3. Additional Information

When integrating both Firebase and Google AdMob, you may encounter the following error:

java.lang.NoClassDefFoundError: Failed resolution of: Lcom/google/android/gms/ads/rewarded/RewardedAd

This issue arises due to conflicts between the Firebase and Google AdMob SDKs.

Solution: Use the Firebase Ads SDK version that matches the Google AdMob version, and comment out the original play-services-ads dependency.

// Example version; ensure the Firebase version matches the one recommended by TradPlus
// implementation 'com.google.android.gms:play-services-ads:22.0.0'
implementation 'com.google.firebase:firebase-ads:22.0.0'
