错误：找不到符号类ConsentInformation

Question

在将compileSdkVersion从版本25升级到28之后，我重新构建了项目 我收到这些错误：

error: cannot find symbol class ConsentInformation  
error: cannot find symbol variable ConsentInformation   
error: cannot find symbol class ConsentInfoUpdateListener   
error: cannot find symbol class URL 
error: cannot find symbol class MalformedURLException   
error: cannot find symbol class ConsentFormListener 
error: cannot find symbol variable form 

这是MainActivity.java的脚本：
