Question

我是android studio的初学者，我得到了运行时错误

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

我搜查了一下，找不到任何东西，我认为它可能与我的清单文件有关。这是我的清单。

继承我的依赖。这个错误可能就好了。

当我同步我的gradle时，我没有收到错误，但为了以防万一。

程序类型已存在意味着什么？
