android - java.lang.RuntimeException : stub only when proguard enabled true 错误

Question

我编写了一个示例应用程序，其中我从本地主机获取数据...一年前创建了这个应用程序，最后一次使用是在上周或最多到最多 2 周前，应用程序运行良好，一切如符合我的预期

更新

Resolved this issue by disabling proguard, but I want to enable like, I've enabled earlier

突然，应用程序停止从本地主机获取数据，看不到更多，但这是我在日志中发现的:

所以基本上，您的类、字段在混淆过程中被重命名，因此导致此错误。解决这个问题的最简单方法是在 pro guard 规则文件中添加你不希望被混淆的类的完整类名。引用:ProGuard - Obfuscating apk causing error
