【问题描述】：

minifyEnabled - true 在调试模式下不适用于 android。我必须混淆我的 Android 项目。我尝试了以下链接，但没有一个对我有用。

1.proguardRelease FAILED when compiling apk with assembleRelease in Android Studio

2.Proguard minifyEnabled true for debug build, not working on pre-Lollipop

以下是我的应用程序构建 gradle 文件

【解决方案1】：

请尝试一下，并为您正在使用的库使用适当的 proguard 规则。 Proguard 会混淆甚至来自第三方库的每个类，除非您为这些类设置特定规则。 

debug {
        minifyEnabled true
        debuggable false
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
    }

常用proguard sn-ps： https://github.com/krschultz/android-proguard-snippets

【讨论】：

  • 感谢您的回复。我应该在应用程序 build.gradle 中使用“proGuard false”还是“debuggable false”？
  • minifyEnabled true debuggable false - 不工作
【解决方案2】：

你说你得到了以下异常：

错误：任务“:app:transformClassesAndResourcesWithProguardForDebug”执行失败。 > java.io.IOException: 请先更正上述警告。

Proguard 和 Dexguard 会混淆代码并显示大量警告，但这并不意味着您的应用无法运行。问题在于，使用默认配置，编译将在每次警告时停止。然而，大多数时候忽略这些警告是一个合理的选择。要尝试此操作，请使用以下命令：

-ignorewarnings 指定打印有关未解决的引用和其他重要问题的任何警告，但继续处理 任何情况。忽视警告可能很危险。例如，如果 确实需要未解析的类或类成员 处理，处理后的代码将无法正常运行。只使用 如果您知道自己在做什么，请选择此选项！

或者如果你想单独指定类或包（更好的选择）：

-dontwarn [class_filter] 指定根本不警告未解决的引用和其他重要问题。可选过滤器是一个正则表达式； DexGuard 不会打印有关名称匹配的类的警告。忽视警告可能很危险。例如，如果确实需要处理未解析的类或类成员，则处理后的代码将无法正常运行。仅当您知道自己在做什么时才使用此选项！

这不是最佳和/或最终解决方案。警告可能意味着您的应用正在混淆应该保留的类，但至少这样您可以运行并稍后查看错误（例如 ClassNotFoundException）。

如果这不能解决您的问题，请尝试通过添加以下命令来获取错误的堆栈跟踪：

-详细 指定在处理期间写出更多信息。如果程序因异常而终止，此选项将打印出整个堆栈跟踪，而不仅仅是异常消息。

【讨论】：

  • 嗨 Styehard，感谢您的回复，当我在 Debug 或 Release 中构建项目时，它无法正常工作，给出我在 Exception 中提到的上述错误。请您查看 Exception 并提供帮助请告诉我。在此先感谢
  • 添加行 -ignorewarnings 并告诉我你是否仍然得到异常。您在示例中添加的“异常”实际上并没有显示错误，只是像我之前解释的那样在 proguard 应用程序中正常显示的警告。
  • 是的，仍然出现异常。
  • 请添加 -verbose 并尝试获取确切的错误消息。使用 -ignorewarnings 它应该让你运行你的应用程序，然后在运行时得到错误
  • 添加 -igonrewarnings, -verbose 后出现问题 -----Error:warning: Ignoring InnerClasses attribute for an anonymous inner class Error:(android.support.design.widget.ai) that doesn't带有一个错误：关联的 EnclosureMethod 属性。这个类可能是由不针对现代 .class 文件格式的错误：编译器生成的。推荐的错误：解决方案是从源代码重新编译类，使用最新的编译器错误：并且不指定任何“-target”类型选项。忽视的后果
【解决方案3】：

将此添加到您的proguard-rules.pro

-dontwarn javax.naming.**
-dontwarn javax.servlet.**
-dontwarn org.slf4j.**
