具有混淆和优化功能的番石榴ProGuard配置

Question

寻找一个用于Guava的ProGuard配置，该配置将混淆和优化，因为网站上提供的默认配置不会。

不仅我无法让它导出我的apk，我还不断得到：

Warning: com.google.common.collect.MinMaxPriorityQueue: 
    can't find referenced field 'int UNSET_EXPECTED_SIZE' in class  
    com.google.common.collect.MinMaxPriorityQueue$Builder
You should check if you need to specify additional program jars.

Answer 1

从 Guava 17.0 开始，这是我在 ProGuard 配置中需要的：

-dontwarn javax.annotation.**
-dontwarn javax.inject.**
-dontwarn sun.misc.Unsafe

否则，生成将失败，并显示如下警告：

Warning: com.google.common.base.Absent: 
   can't find referenced class javax.annotation.Nullable

(这是因为 Guava 使用的注释不属于 Android 运行时 (android.jar(。在这种情况下，只需将警告静音即可。

如果您使用 Gradle 作为构建工具，则在使用 Guava 时，上述proguard-project.txt和build.gradle中的以下内容会生成经过优化和混淆的 APK。

buildTypes {
    release {
        minifyEnabled true
        proguardFile file('proguard-project.txt')
        proguardFile getDefaultProguardFile('proguard-android-optimize.txt')
    }
}

---

或者，您可以在build.gradle依赖项中包含 jsr305.jar 的依赖项：

compile 'com.google.code.findbugs:jsr305:2.0.2'

。ProGuard 配置中只有-dontwarn sun.misc.Unsafe，但我更喜欢将-dontwarn也用于javax的东西。

Answer 2

从 23.4-android 升级到 23.5-android 时，我必须将以下行添加到我的 proguard 规则文件中：

-dontwarn afu.org.checkerframework.**
-dontwarn org.checkerframework.**

下面列出了我从更新中看到的 proguard 警告(在添加新规则之前(以供参考：

Answer 3

构建R8的工程师之一(Stephan Herhut(在Google I/O 2018的此会话中列出了最新番石榴(25.0-android(的以下规则：

-dontwarn afu.org.checkerframework.**
-dontwarn org.checkerframework.**
-dontwarn com.google.errorprone.**
-dontwarn sun.misc.Unsafe
-dontwarn java.lang.ClassValue

该视频还包括对规则的简短解释(前 3 个是静态分析注释框架，后 2 个是 Android 上不可用的类，这些类受 Guava 中的运行时检查保护(。

会议结束后，我与斯蒂芬进行了交谈，他说这些有望在未来包含在番石榴文档中，或者更好地包含在未来番石榴版本的consumerProguardFiles中。这是希望！

Answer 4

现在 Guava 19.0 发布，我发现我必须添加这些规则。

-keep class com.google.j2objc.annotations.** { *; }
-dontwarn   com.google.j2objc.annotations.**
-keep class java.lang.ClassValue { *; }
-dontwarn   java.lang.ClassValue
-keep class org.codehaus.mojo.animal_sniffer.IgnoreJRERequirement { *; }
-dontwarn   org.codehaus.mojo.animal_sniffer.IgnoreJRERequirement

Answer 5

对于番石榴 20.0，您还需要添加：

# Guava 20.0
-dontwarn com.google.errorprone.annotations.CanIgnoreReturnValue
-dontwarn com.google.errorprone.annotations.concurrent.LazyInit
-dontwarn com.google.errorprone.annotations.ForOverride

Answer 6

此消息建议以下解决方法：

-dontwarn com.google.common.collect.MinMaxPriorityQueue 

我想可以改变Proguard以使其变得不必要，但我们尚未与其所有者核实。

Answer 7

番

石榴 20.0 的总保护规则。目前，最新的番石榴21不支持Android。

-dontwarn com.google.common.base.**

-dontwarn com.google.errorprone.annotations.**
-keep class com.google.errorprone.annotations.** {*;}
-dontwarn   com.google.j2objc.annotations.**

-dontwarn   org.codehaus.mojo.animal_sniffer.IgnoreJRERequirement

Answer 8

我只想在build.gradle中与以下内容分享现在对我的应用程序实际有用的内容：

编译 'com.google.guava：guava：23.5-android'

以下是在Proguard项目中.txt处理番石榴。 它本质上是TimTron的答案和develper_7提示的结合：

-dontwarn sun.misc.Unsafe
-dontwarn com.google.common.collect.MinMaxPriorityQueue
-dontwarn com.google.common.util.concurrent.FuturesGetChecked**
-dontwarn javax.lang.model.element.Modifier
-dontwarn afu.org.checkerframework.**
-dontwarn org.checkerframework.**

Answer 9

guava 的 jar 文件是由一个 Java 编译器生成的，该编译器(与 javac 不同(在同一源文件中的引用类常量池中保留了对私有内联常量的额外引用，这仅在 ProGuard 4.7 中失败，这似乎优化了私有常量定义，而没有优化引用。 未来的番石榴罐文件将没有如此恒定的池引用，但 Proguard 4.7 中可能存在一个错误，该错误不会在标准 javac 生成的 jar 文件中表现出来。

Answer 10

这些保护规则对我有用：番石榴23.3-android

-dontwarn sun.misc.Unsafe
-dontwarn com.google.common.collect.MinMaxPriorityQueue
-dontwarn com.google.common.util.concurrent.FuturesGetChecked**
-dontwarn javax.lang.model.element.Modifier
