NoClassDefFoundError: Could not initialize class org.xnio.channels.Channels

NoClassDefFoundError这个错误一般就两种情况，
1、没有引入相应的jar包
2、两个jar包中都有这个class，无法确认是引用的哪一个，就是jar冲突

jar包依赖 出现java.lang.NoClassDefFoundError异常
场景一：A.jar和B.jar两个文件(非原生)，其中B.jar是依赖A.jar生成。B.jar生成后将其导入android工程内(不进行A.jar导入)，操作B.jar中的私有接口正常运行，但操作A.jar实现接口时会<em>报</em><em>NoClassDefFoundError</em>异常；A.jar同B.jar一并导入工程异常消失。 场景二：B.jar依赖apache HttpClient.jar包生成时，仅将B.jar导入工程时，调用HttpClient.jar内接口不会出现<em>NoClassDefFoundError</em>异常。 不知场景一、二的区别是什么？

Java学习的正确打开方式
在博主认为，对于入门级学习<em>java</em>的最佳学习方法莫过于视频+博客+书籍+总结，前三者博主将淋漓尽致地挥毫于这篇博客文章中，至于总结在于个人，实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍，博客次之，这又是一个层次了，这里暂时不提后面再谈。博主将为各位入门<em>java</em>保驾护航，各位只管冲鸭！！！上天是公平的，只要不辜负时间，时间自然不会辜负你。 何谓学习？博主所理解的学习，它是一个过程，是一个不断累积、不断沉淀、不断总结、善于传达自己的个人见解以及乐于分享的过程。
