根据我发现与类名冲突有关的那些问题?如果我错了,请纠正我.
As per I'd found those issues related to class name conflict? Correct me if I'm wrong.
下面是我的build.gradle

推荐答案
当build.gradle文件中存在不同类型的依赖项时喜欢
When different types of dependency present in build.gradle filelike
implementation 'com.android.support:appcompat-v7:27.1.0'
和
implementation 'com.android.support:design:28.0.0'
或版本冲突.
为避免这种情况,您需要维护依赖项的版本 像这样
to avoid this you need to maintain the version of your dependency like this
implementation 'com.android.support:appcompat-v7:27.1.0'
implementation 'com.android.support:design:28.0.0'
