我使用 Proguard 来混淆我的代码，并使其更小。我使用 Eclipse 进行构建，并且使用了一段时间。我最近有一个在调试版本中运行良好的构建，我正在尝试发布它。在过去一天的大部分时间里，我一直在努力完成这项工作，但当我尝试使用已发布的构建运行我的代码时，我不断收到以下错误(如果有帮助，我可以生成更多)。

02-25 16:39:58.844: E/AndroidRuntime(27593): Caused by: java.lang.ClassNotFoundException: Didn't find class "com.kd7uiy.hamfinder.MainActivity" on path: DexPathList[[zip file "/data/app/com.kd7uiy.hamfinder-2.apk"],nativeLibraryDirectories=[/data/app-lib/com.kd7uiy.hamfinder-2, /vendor/lib, /system/lib]]

真正奇怪的是，我没有更改我的proguard 文件，至少不是我第一次这样做。从那以后我就一直在玩它，看看我能不能得到任何东西让它工作，但似乎没有什么能解决问题。自此构建以来，我在我的代码库中添加了一个新库 Google Maps utility library .我的最后一次构建是在几天前。

在尝试解决此问题时，我发现路径列表中没有出现整个文件夹。我在已编译的二进制类中看到了这个文件夹，但它们无法在这个过程中存活下来。如果我停止使用 Proguard，发布版本将按预期运行。

我的代码依赖于 /src 目录中的 6 个包。我没有为这个版本显着改变这个结构，虽然我可能添加了一两个文件到不同的文件夹，并且可能移动了一两个文件夹。这 6 个包是:

com.kd7uiy.hamfinder
com.kd7uiy.hamfinder.dialogs
com.kd7uiy.hamfinder.ObserverOutPairs
com.kd7uiy.hamfinder.Subjects
com.kd7uiy.library
com.robobunny

其中，我在我的 proguard 映射文件中找不到以下包的直接证据，至少对于这个特定的试验而言

com.kd7uiy.hamfinder
com.kd7uiy.hamfinder.ObserverOutPairs
com.kd7uiy.hamfinder.Subjects

有些引用了一些变量名，但没有包含整个包的证据。我检查了 .dex 文件，它也不包含丢失的包。我应该补充一点，有时看似随机的一些其他包会出现，但永远不会出现我的 MainActivity 所在的 com.kd7uiy.hamfinder。有时它们都不出现。

这是我的 project.properties 文件:

# To enable ProGuard to shrink and obfuscate your code, uncomment this (available properties: sdk.dir, user.home):
proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt

还有我原来的 proguard-project.txt 文件，它已被证明不起作用。

我确实对其进行了更改，以便为 Proguard 添加适当的 Google map 所需的更改。都没有用。

这是我的文件的快照

这是我的构建路径

查看其他一些文件，我在 /bin/proguard.txt 文件中看到了这些文件的证据，但之后它们似乎就消失了。编译后的大小也没有明显变小，但这可能是因为我的非代码内容比代码多得多，很难检测到几个 java 文件的差异。这是整个/bin/proguard.txt 文件。

我已经尝试了很多方法来让它工作，包括升级 proguard、更新 SDK、更新 Eclipse 工具、下载新版本的 Eclipse 并从头开始，对 proguard 文件进行了大量更改，没有其中似乎有丝毫帮助。还有其他想法吗？

编辑 - 作为一种可能性，我倾向于以下几点。

1. 我注意到警告列表发生了变化，即使我只是清理项目并重新构建。
2. 错误的数量似乎随着我打开 eclipse 和构建构建的次数而增加。
3. Eclipse 似乎因堆错误而更频繁地崩溃。

不确定这些是否有帮助，但我想我会把它扔进去。

现在你有

# We want to keep methods in Activity that could be used in the XML attribute onClick
-keepclassmembers class * extends android.app.Activity {
   public void *(android.view.View);
}

您的类扩展了 v7 支持库(从您的 project.properties 判断)而不是标准的 android.app.Activity，因此您需要如下内容:

-dontwarn android.support.v7.**
-keep public class * extends android.support.v7.app.Fragment
-keep public class * extends android.support.v4.app.Activity

或者如果你想尝试保留更多(但更大的最终 apk):

-keep class android.support.v7.** { *; }

hoặc

# We want to keep methods in Activity that could be used in the XML attribute onClick
-keepclassmembers class * extends android.support.v7.app.ActionBarActivity {
   public void *(android.view.View);
}

vì Fragment 等也是如此

请注意您的日志显示无法找到 LogBookFragment$OnEditView 这是一个内部类 View 。要么将它们一一列出以由混淆器保存，要么将它们移出到它们自己的类文件中。

关于android - Proguard 似乎删除了路径中包含的整个包，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/22027219/
