我的Thrift客户端库和我的应用程序项目中很少生成thrift java类。需要帮助弄清楚为什么未使用的Thrift客户端库和生成的类没有被Proguard剥离。
我已确认已启用代码收缩
minifyEnabled true
proguardFiles file('proguard-android.txt')
我完全注释掉了我的应用程序中的Thrift用法。[早期在我的代码中我只使用了一个带Thrifts TDeserializer和TSerializer类的生成类，并期望Proguard不保留TServer等类，因为它们没有被使用。但是我注意到它仍然存在。为了确保它不是间接保留Thrift客户端类的生成类，我没有对它进行全部评论]
即使没有人实际调用我的应用程序代码中的com.test.thrift.Task，seeds.txt仍然显示其中的com.test.thrift.Task。
我尝试调试未移除类的原因：
使用
-verbose
-whyareyoukeeping class com.offerup.android.thrift.Task { public * ; }
它唯一显示的是com.offerup.android.thrift.Task 由配置中的指令保存。
我试图删除下面的一些候选人。似乎没有任何区别。除了蛮力删除所有东西并搞清楚配置条款的方法之外，还有更好的方法来了解为什么这些类被保留了吗？

我有类似的问题，但ProGuard没有告诉你哪个指令强制保留类。但是，通过查看您的配置，我怀疑这一行可能是罪魁祸首：
-keep class !android.support.v7.view.menu.**,!android.support.design.internal.NavigationMenu,!android.support.design.internal.NavigationMenuPresenter,!android.support.design.internal.NavigationSubMenu,** {*;}
我怀疑最后**可能会强制保留所有课程，包括你的课程。
此外，您可以使用ClassyShark分析APK中的类和方法，而无需安装APK，因此您可以做的一件事是通过规则进行二元搜索以查看哪个正在制作上课。
