问题：
在做一个音乐项目中，使用到了AIDL跨进程通信组件，编写一个简单的AIDL时候，编译一直无法通过，报错内容
Error:Execution failed for task ':app:compileDebugAidl'.

绞尽脑汁，又是google又是度娘，都没有合适解决办法，最终发现有两个问题:
- 实体类没有使用in 、out 、inout 中任何一种方法修饰，导致编译失败
后来为添加了in 修饰后，依然无法通过，最终发现问题所在 - 在设置方法时候， 设置了同名不同参数方法，在AIDL中不可以这样命名，导致编译无法通过，懊恼不已，浪费大量时间
后记：
开发中一定要够自信，够清醒，不然真是浪费时间
