这里，如果我使 minify enabled = false 代码运行正常，而如果我使用 true，则代码显示

Answer 1

如果启用缩小，构建将调用 Proguard 去除所有不必要的类、成员和方法。为此，您需要一个 proguard 配置文件，该文件将告诉 Proguard 哪些类是您的类的入口点以及应该保留哪些成员和方法。您看到的错误是不匹配方法调用的常见错误。

错误包括指向 Proguard 的链接手册，对错误进行更多描述:您必须确保您使用的是正确的 Android Build Target，并且您保留了所有必要的库及其方法。

尝试在您的属性中调整 Android Build Target。如果这不起作用，您将必须检查您的混淆器配置中是否需要更多条目。
