这篇博客讨论了Android开发中遇到的依赖冲突问题，特别是Duplicate Class错误。错误日志显示多个库中存在重复的类，如android.support.v4包下的多个类。解决方法是通过排除特定模块，例如使用`exclude group`来避免冲突。博客提醒开发者检查并调整Gradle配置，以确保只保留必要的依赖，从而解决冲突。

先看看网上的方法是怎么样的：

 implementation ('com.android.support:support-fragment:28.0.0'){
        exclude group: "com.android.support",module: 'versionedparcelable'
    }

是我盲区，上述对我无效，没能解决，~~当场哭了~~

`我们来看看错误日志长啥样`
