本文主要是介绍给Android.mk添加 '-dontwarn' 属性，避开第三方jar包错误，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

平台 引用第三方jar包 报错， 而报错内容不影响使用，可以使用 '-dontwarn'

Warning: there were 14 unresolved references to classes or interfaces.You may need to add missing library jars or update their versions.If your code works fine without the missing classes, you can suppressthe warnings with '-dontwarn' options.(http://proguard.sourceforge.net/manual/troubleshooting.html#unresolvedclass)
Error: Please correct the above warnings first.

解决方案：

1. android.mk添加命令

   LOCAL_PROGUARD_FLAG_FILES := proguard.cfg

   
   
2. 和android.mk同目录下，添加文件proguard.cfg，文件内容：（即后面跟随包名，是的只有一行）

   -dontwarn okio.**
