集成Meta Audience Network到AdMob中介时出现NoSuchMethodError崩溃问题

问题详情 #

将Meta Audience Network集成到AdMob中介后，直接用AdMob加载广告正常，但通过Mediation Test Suite启动广告时应用崩溃，报错信息如下：

java.lang.NoSuchMethodError: No virtual method addNetworkExtrasBundle(Ljava/lang/Class;Landroid/os/Bundle;)Lcom/google/android/gms/ads/AdRequest$Builder; in class Lcom/google/android/gms/ads/AdRequest$Builder; or its super classes (declaration of 'com.google.android.gms.ads.AdRequest$Builder' appears in /data/app/~~oKlg38Jc4VCuldv5j8yjbw==/in.animall.android-j-38kGYKedQ-_97P08tWkw==/base.apk!classes19.dex)

当前使用的依赖版本：

facebook-mediation = "6.18.0.0"
playServicesAds = "23.4.0"
mediationTestSuite = "3.0.0"
play-services-ads = { group = "com.google.android.gms", name = "play-services-ads", version.ref = "playServicesAds" }
google-ads-facebook = { group = "com.google.ads.mediation", name = "facebook", version.ref = "facebook-mediation"}
mediation-test-suite = { group = "com.google.android.ads", name = "mediation-test-suite", version.ref = "mediationTestSuite" }

问题原因 #

这个NoSuchMethodError是依赖版本不兼容导致的：Mediation Test Suite 3.0.0要求Google Ads SDK最低版本为24.0.0，但你使用的play-services-ads版本是23.4.0，低于要求版本，导致Test Suite调用了该版本SDK中不存在的addNetworkExtrasBundle方法。

解决方案 #

1. 升级Google Ads SDK版本 #

将playServicesAds版本升级到24.0.0或更高，确保与Mediation Test Suite 3.0.0兼容。修改后的依赖配置示例：

facebook-mediation = "6.18.0.0"
playServicesAds = "24.0.0"
mediationTestSuite = "3.0.0"
play-services-ads = { group = "com.google.android.gms", name = "play-services-ads", version.ref = "playServicesAds" }
google-ads-facebook = { group = "com.google.ads.mediation", name = "facebook", version.ref = "facebook-mediation"}
mediation-test-suite = { group = "com.google.android.ads", name = "mediation-test-suite", version.ref = "mediationTestSuite" }

2. 验证适配器兼容性 #

当前使用的facebook-mediation:6.18.0.0适配Google Ads SDK 23.3.0及以上版本，升级到24.x版本无需更换适配器版本，可直接兼容。

3. 清理并重构项目 #

同步项目依赖后，执行清理（Clean Project）和重新构建（Rebuild Project）操作，确保新依赖生效。

备选方案（不推荐） #

如果暂时无法升级Google Ads SDK，可以降级Mediation Test Suite到兼容23.4.0的版本（如2.0.0），但推荐优先升级SDK到最新稳定版，以获得更好的兼容性和功能支持。
