使用Admob中介的Adcolony在Flutter应用程序中不起作用

Question

我目前正在使用Google Admob在我的应用程序中显示广告，我想添加中介，因为我对我的填充率不满意。我按照他们在网站上的步骤，通过调解整合Adcolony。我添加了adcolony.jar文件，并使用Android Studio将其与Gradle同步。在集成过程中，我在应用程序级别的build.gradle、中添加了这些行

repositories {
    jcenter()
    maven {
      url  "https://adcolony.bintray.com/AdColony"
    }
}
...
dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'androidx.appcompat:appcompat:1.0.2'
    implementation 'com.google.android.gms:play-services-ads:19.0.0'
    implementation 'com.google.ads.mediation:adcolony:4.1.3.1'
}
...

运行应用程序后，调试控制台会抛出以下错误：

Duplicate class com.iab.omid.library.adcolony.walking.a.e found in modules jetified-adcolony.jar (adcolony.jar) and jetified-sdk-4.1.3-runtime.jar (com.adcolony:sdk:4.1.3)

我已经缩短了我的错误，但主要是因为发现了重复的类，我不知道如何在我的build.gradle中排除这么多类。请帮忙。

要集成广告中介，您需要按照网站上提到的所有步骤操作，但不是使用build.gradle，而是我从adcolony repo手动添加了适配器。Google Admob中介网站已过时，请使用此链接了解如何集成广告适配器。
