在Android开发中使用EventBus遇到'Subscriber class *** and its super classes have no public methods with the @Subscribe annotation'错误。本文介绍了如何通过在BaseActivity中添加公共的@Subscribe注解方法来解决这个问题。

相信很多小伙伴在安卓开发中都用到了eventbus。
有没有遇到坑呢？
Subscriber class *** and its super classes have no public methods with the @Subscribe annotation
在实际使用过程中，注册之后，会报找不到公共的注解方法，需要在注册的地方实现一个公共注解方法

EventBusTag 是自己定义的对象，里面存放了一些常用的值。
