我尝试在Android Studio中构建一个模块.它似乎在设备上运行但是当我尝试构建APK时,我收到了一个错误：

Program type already present: com.facebook.ads.Ad

这是完整的日志：

基于我在其他问题中找到的答案,到目前为止我尝试的是：

>清洁&重建.
>清洁&制作项目.
>重启Android Studio.
>确保multiDexEnabled设置为true.
>更改JDK版本.
>更改Gradle版本.

这些都不适合我.此外,当我尝试通过./gradle app：dependencies在树中查找依赖项时,我找不到任何类型：com.facebook.ads.Ad.我该如何解决这个问题？

解决方法:

首先检查您是否已在gradle文件中实现

实现facebook_ads_from_jcenter’和inlibs`文件夹…

应该只有一种方法来实现sdk.

如果你仍然有问题尝试使用resolutionstrategy强制Facebook广告.

例如：

configurations.all {
    resolutionStrategy.force "`(facebook_sdk)`"
}
