Proguard：找不到引用字段＆＃39; java.lang.Boolean default＆＃39;在课堂上FooImpl。怎么了？

Answer 1

确保使用像这样的proguard属性文件

-injars in_name_of_ajr.jar
-outjars out_jar.jar
-printmapping mappingfile_name.map
**-libraryjars  <java.home>/lib/rt.jar**  // this is solution for ur question 
-libraryjars  .. any other jar location if you user them as libs in your project

-target 1.7 // java version
-keep public class your_package_name.MainClass { 
      public static void main(java.lang.String[]); 
}
