android - Proguard 给出 "Warning: org.msgpack.*"

Question

使用 Eclipse 导出我的项目时，我收到以下警告:

[2013-08-20 10:45:24 - MyProj] Proguard returned with error code 1. See console
[2013-08-20 10:45:24 - MyProj] Note: there were 3023 duplicate class definitions.

我使用的一些第三方东西是 mixpanel.com、parse.com、ActionBarSherlock ( http://actionbarsherlock.com/ ) 和 TestFlightApp.com .

我确实尝试将以下内容放入我的 proguard-myproject.txt 中:

-dontwarn javassist.**
-dontwarn javax.tools.**
-dontwarn json.simple.parser.**

但是，如果我将它们放入我的应用程序中，我会在启动应用程序后立即崩溃，所以我猜我需要通过正确包含库来清除警告。

问题:

我想知道我需要在我的 proguard-myproject.txt 文件中包含什么来消除这些警告并能够在我的手机上启动我的应用程序而不会在我启动应用程序后立即崩溃。如果我仅在正常的 Run.. 或 Debug 选项中从 eclipse 运行该应用程序，该应用程序工作正常，所以我猜测 Proguard 以某种方式删除了我需要的一些类。

我也有 dump.txt、mapping.txt、seeds.txt 和 usage.txt，如果有人需要看的话，但它们相当长，所以我认为暂时不需要粘贴到这里。

已解决!

感谢@Eric Lafortune 并期待 proguard documentation

主要问题是添加这个:

-keep class com.myapp.** { *; }
-keep interface com.myapp.** { *; }

com.myapp.** 是我的应用程序包

Answer 1

Android SDK 中的 Ant/Eclipse/Gradle 构建过程会自动为您指定输入 jar、库 jar 和输出 jar，因此您不得在配置中再次指定它们。这就是为什么您会收到很多关于重复类的警告。

另一方面，一些 org.msgpack 类依赖于不在您的 libs 目录中的类。如果您的调试构建工作正常，您可以告诉 ProGuard 忽略它:

-dontwarn org.msgpack.**

如果您的应用程序崩溃，您应该查看 logcat 输出。您可以在 Troubleshooting 中找到建议ProGuard 手册的一部分。
