我在android上使用proguard，我注意到它保留了我的单例类名称。 任何人都可以告诉我为什么或如何告诉它混淆它们？

答案 0 :(得分：0)
确保您已禁用或删除了以下行，因为这可能会导致您的类无法重命名，
#pragma omp parallel for虽然您已在Proguard文件中注释了这些行，但您只是验证它是否未启用。
如果您的Proguard有-keep public class * {
public protected *;
}
wihch保留类名，并且任何具有静态字段的类都不会更改其名称。将其更改为'-keepclasseswithmembers'将模糊类名称。
希望它有所帮助！
