从 Eclipse 到 Android Studio:为什么在不构建 Release 时使用 proguard.cfg? [英] From Eclipse to Android Studio: Why is proguard.cfg used when NOT building Release?

问题描述

因此，我一直在尝试将多项目(即 Eclipse 项目)应用程序的开发迁移到 Android Studio (v1.1).

So, I have been trying to migrate the development of a multi-project (eclipse projects that is) app to Android Studio (v1.1).

通过文件导入 > 导入项目非常简单，而且没有发生任何意外.

Importing via File > Import Project was really easy and went without incident.

然而，当我尝试 Make/Rebuild 项目时，我遇到了许多惊喜.第一个，与 Proguard 无关，与源文件编码有关(最初在 Windows-1252 中)，但我很快找到了使用这个 Windows-1252 > 重新加载 > UTF-8 > 转换 答案.

However, when I tried Make/Rebuild project I encountered numerous surprises. The first, not Proguard-related, had to do with source file encoding (originally in Windows-1252), but I quickly found a solution using this Windows-1252 > Reload > UTF-8 > Convert answer.

然后，我的 com.comp.mod.X 类的错误:找不到符号类".然后我通过转到包含该类的模块(Android Studio 模块，即以前的 Eclipse 项目)解决了这个问题，并将以下内容添加到其 proguard.cfg:

Then, "error: cannot find symbol class" for a com.comp.mod.X class of mine. I then solved it by going to the module (Android Studio module that is, previously an Eclipse project) that contains that class and added to its proguard.cfg the following:

-keep public class com.comp.mod.X

对于在上述类中定义的 const BB，这给我留下了错误:找不到符号变量".我通过向相同的 proguard.cfg 添加以下内容解决了这个问题:

Which left me with an "error: cannot find symbol variable" for a const BB defined in the aforementioned class. I solved this by adding to the same proguard.cfg the following:

-keepclassmembers class com.comp.mod.X {
    public static final boolean BB;
}

这让我只剩下一个错误:找不到符号方法 getPreferenceX()".我通过添加到相同的 -keepclassmembers 方法来解决这个问题，这样上面现在看起来:

That left me with only one "error: cannot find symbol method getPreferenceX()". I solve this by adding to the same -keepclassmembers that method, so that the above now looks:

-keepclassmembers class com.comp.mod.X {
    public static final boolean BB;
    public static java.lang.String getPreferenceX();
}

我以为我已经完成了，但令我沮丧的是，当我尝试重建项目时，我收到了来自项目中其他模块的许多额外错误，所有类型都为错误:找不到符号类/变量/方法" 并且与一些 proguard.cfg 相关.

I thought I was done, but to my dismay, when I attempted to rebuild the project, I received numerous additional errors from other modules in the project, all of the type to "error: cannot find symbol class/variable/method" and related to some proguard.cfg.

我本可以继续为每个模块删除 proguard.cfg 文件，但此时我开始怀疑我在做一些根本错误的事情，因为这些 proguard.cfg 文件在 Eclipse 下运行良好.所以，

I could have continued butchering the proguard.cfg files for each and every module but at this point I am beginning to suspect that I am doing something fundamentally wrong, because those proguard.cfg files work perfectly under Eclipse. So,

1. 为什么突然间这些对 Android Studio 不再有用?
2. 如果 ProGuard 仅在您在 发布版 模式，为什么基于 Android Studio 的构建会因为 Proguard 的混淆而抱怨找不到符号"?

我错过了什么?

注意:我未尝试生成签名的 APK".我所做的只是重建项目".

Note: I have not attempted "Generate Signed APK". All I do is "Rebuild Project".

推荐答案

目前(截至 2015-04-24)，minifyEnabled 的默认值为 false多模块项目的所有构建类型都不正确，其中一些模块(包括应用程序)依赖其他模块.这是由于 错误 #52962 导致构建类型<强>不传播到库——它们总是被构建为 RELEASE.

Currently (as of 2015-04-24), minifyEnabled's default value of false for all build types is incorrect for multi-module projects, in which some modules (app included) are dependent on other modules. This is due to bug #52962 that causes build types to not propagate to libraries -- they are always built as RELEASE.

欢迎提出解决此错误的建议或对其修复的通知.

Suggestions to work around this bug or notifications of its fix are most welcome.
