程序类型已存在：android.support.v7.util.AsyncListUtil $ 1

Question

我已经认识到已经存在一些“程序类型已经存在”的问题，但似乎没有人完全解决（或帮助）我的情况：我得到“程序类型已存在：android.support.v7.util.AsyncListUtil $ 1 “ - 我认为这是从我从exoplayer 2.7更新时开始的。 exoplayer 2.8

Program type already present: android.support.v7.util.AsyncListUtil$1
Message{kind=ERROR, text=Program type already present: android.support.v7.util.AsyncListUtil$1, sources=[Unknown source file], tool name=Optional.of(D8)}

有一次，Android Studio停止抱怨AsynListUtil，但开始对Annotations.AnyRef说同样的话。

build.gradle粘贴在下面。任何帮助，将不胜感激。我已经解决了Android Studio标记的任何依赖/库冲突，并完成了“工具>清理项目”，“工具>重建项目”和“文件>无效缓存/重新启动”

}

更新：

我开始认为它可能与Firebase相关，如：Android Studio- Program type already present: com.google.android.gms.internal.measurement.zzwp

因此删除了我的代码中的Firebase依赖项和引用，但仍然得到：

Program type already present: android.support.annotation.AnyRes
Message{kind=ERROR, text=Program type already present: android.support.annotation.AnyRes, sources=[Unknown source file], tool name=Optional.of(D8)}

Answer 1

解决了。在我的例子中，我在/ libs文件夹中找到了android-support-v4-23.1.1和android-support-v7-recyclerview-23.1.1。在更新exoplayer和Firebase之前，他们没有给我带来任何问题。删除那些允许我再次编译和部署没有错误。不完全确定他们是如何在那里获得的，但我认为他们是从广告中介网络的图书馆软件包安装中留下的。
