我有一个包含以下模块的应用程序:

/app
/common
/customviews
/model

现在我想混淆我的生产代码，所以我将以下行放在所有模块的所有 build.gradle 文件中。

buildTypes {
    release {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

此文件包含以下规则:

-dontnote android.net.http.*
-dontnote org.apache.commons.codec.**
-dontnote org.apache.http.**


-dontwarn okhttp3.**
-dontwarn okio.**
-dontwarn javax.annotation.**
-dontwarn org.conscrypt.**
-dontwarn retrofit2.Platform$Java8


-keepnames class okhttp3.internal.publicsuffix.PublicSuffixDatabase

-keep class com.google.android.gms.** { *; }
-dontwarn com.google.android.gms.**

应用程序编译正常，但是在运行时出现以下异常:

顺便说一句，我正在使用 Kotlin。

最佳答案

Proguard 仅与实际版本相关。因此，不是为每个模块添加 minifyEnabled true，而是仅将其添加到应用本身的发布配置中。

所有来自库的代码(无论是来自模块还是外部依赖项)都将与应用程序代码混淆。

如果您想与您的库共享自定义规则，您可以定义要添加到 AAR 的 consumerProguardFiles 'proguard-rules.pro'文件。

关于android - 多模块应用程序上的 Proguard，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/50737180/
