混淆工具Proguard出现“警告：org.msgpack.*”

androidproguard

使用Eclipse导出我的项目时，我收到了以下警告：
[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.

我正在使用一些第三方工具，包括mixpanel.com、parse.com、ActionBarSherlock（http://actionbarsherlock.com/）和TestFlightApp.com。

我尝试将以下内容添加到我的proguard-myproject.txt文件中：

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

然而，如果我将它们放在我的应用中，启动应用后立即崩溃，所以我猜想我需要通过正确包含库来清理警告。

问题:

我想知道我需要在我的proguard-myproject.txt文件中包含什么内容才能消除这些警告并能够在我的手机上启动应用程序，而不会在启动应用程序后立即崩溃。如果我只是从eclipse中运行应用程序，使用普通的Run..或Debug选项，应用程序可以正常工作，因此我猜想Proguard可能会删除我需要的某些类。

如果有人需要查看dump.txt、mapping.txt、seeds.txt和usage.txt，我也有这些文件，但它们相当长，所以我认为现在不需要粘贴在这里。

已解决！

感谢@Eric Lafortune和proguard文档的帮助。

主要问题就是添加以下内容：

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

com.myapp.** 是我的应用程序的包

@TheTerribleSwiftTomato，不知道该如何回复你，只能在评论中留言。无论如何，感谢你提供的信息！希望我能有时间进一步研究这个问题。 - nommer

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，因此您不必在配置中再次指定它们。这就是为什么您会收到许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。如果您的调试构建正常工作，则可以使用以下命令告诉ProGuard忽略它：

-dontwarn org.msgpack.**

如果你的应用程序崩溃了，你应该查看logcat输出。你可以在ProGuard手册的Troubleshooting部分中找到建议。

谢谢！看起来除了我编辑的部分之外，这个问题已经解决了！ - nommer
以管理员身份运行SDK和Eclipse，并将以下代码添加到您的清单文件中：<meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" /> </application> - Chris Sim
