android - 无法使用proguard编译

Question

我的第一个 libgdx 游戏终于接近截止日期了。我有一个小问题。

当我编译签名的 libgdx 应用程序时，我总是会出错。 按照消息 gradle build 和 my proguard file 进行操作。

      You should check your configuration for typos.
      (http://proguard.sourceforge.net/manual/troubleshooting.html#unknownclass)
Note: there were 4 classes trying to access generic signatures using reflection.
      You should consider keeping the signature attributes
      (using '-keepattributes Signature').

Note: there were 27 unkept descriptor classes in kept class members.
      You should consider explicitly keeping the mentioned classes
      (using '-keep').
      (http://proguard.sourceforge.net/manual/troubleshooting.html#descriptorclass)
Note: there were 3 unresolved dynamic references to classes or interfaces.
      You should check if you need to specify additional program jars.
      (http://proguard.sourceforge.net/manual/troubleshooting.html#dynamicalclass)
Note: there were 3 accesses to class members by means of introspection.
      You should consider explicitly keeping the mentioned class members
      (using '-keep' or '-keepclassmembers').
      (http://proguard.sourceforge.net/manual/troubleshooting.html#dynamicalclassmember)
Warning:there were 55 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 suppress
         the warnings with '-dontwarn' options.

我的混淆文件是:

       boolean reportFixture(long);
       float   reportRayFixture(long, float, float, float, float, float);
    }

我该如何解决这个问题？

尝试在混淆文件中添加这一行:

-keep public class com.android.vending.licensing.ILicensingService

如果它不起作用，请尝试我使用的 proguard 文件 cnfig，它对我的​​ libgdx 项目运行良好
