错误的结果

解决方法

根据关键字找到官网的建议方法。

If you don’t feel like filtering out the problematic classes, you can try your luck with the -ignorewarnings option, or even the -dontwarn option. Only use these options if you really know what you’re doing though.

只需要在ProGuard 规则文件build/core/proguard.flags末尾加上过滤信息即可。
在文件上修改，即可。重新执行。

-dontwarn android.hidl.base.**
-keep class android.hidl.base.**

修改后的结果，没有错误
