    ... keeps going till 743 errors (warnings)

我已经尝试了几种方法来防止这种情况发生(-dontskipnonpubliclibraryclassmembers,-keep,-dontwarn,-ignorewarnings)但没有成功.也许我没有正确使用这些选项.我正在使用IntelliJ并针对android-19(Android 4.4.2).

该应用程序使用一些第三方库构建:一些包含在libs文件夹中,另一些则包含在Maven pom.xml中.我怀疑通过pom.xml包含的库未包含在-libraryjars选项中.

我的project.properties看起来像这样:

# 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-optimize.txt:proguard-project.txt

# Project target.
target=android-19

我的proguard-project.txt看起来像这样:

-dontskipnonpubliclibraryclassmembers

# Libraries
-dontwarn org.apache.**

-keep class android.support.v4.app.** { *; }
-keep interface android.support.v4.app.** { *; }

# WebView with JS: specify the fully qualified class name to the JavaScript interface class:
-keepclassmembers class fqcn.of.javascript.interface.for.webview {
   public *;
}

# Database model
-keep class com.mycompany.model.db.**
-keepclassmembers class com.mycompany.model.db.** { *; }

# Project target.
target=android-19

任何想法为什么会这样？

Answer 1

我解决了这个问题。这是由我的 IntelliJ 安装中的配置问题引起的：

项目右键 -> 打开模块设置 -> Facets 选项 -> Compiler 选项卡：

1. 确保 Proguard 已启用
2. 确保配置文件路径应显示：
   • 我们项目中的 proguard-project.txt 文件
   • SDK 中的 proguard-android.txt。

就我而言，它仅显示 SDK 中的文件，因此我对项目中的文件所做的更改不会被考虑在内。

进行此更改后，我可以使用 Proguard 文档中显示的 Proguard 选项并修复这些警告。

文件project.properties由IntelliJ自动生成，不应手动修改。即使此文件显示它正在使用这两个文件进行配置，但这也不一定正确，请查看“设置”对话框。
