Proguard on multimodule app

时间：2018-06-07 09:02:53

标签： android proguard

我有一个由以下模块组成的应用程序：

/app
/common
/customviews
/model

现在我想混淆我的代码用于生产，所以我在所有模块的所有build.gradle文件上添加以下行。

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.**

该应用程序编译正常，但运行时我得到以下异常：

我顺便使用Kotlin。

3 个答案:

答案 0 :(得分：5)

Proguard 仅与实际版本相关。因此，不要为每个模块添加minifyEnabled true，只需将其添加到应用程序本身的发布配置中。

来自库的所有代码（无论是来自模块还是外部依赖项）都将使用应用程序的代码进行模糊处理。

如果您要与图书馆共享自定义规则，则可以定义要添加到consumerProguardFiles 'proguard-rules.pro'文件的AAR。

答案 1 :(得分：0)

如果要将Proguard文件添加到库模块，则应在库的构建的defaultConfig块中将其添加到consumerProguardFiles而不是proguardFiles的正确属性中。 gradle文件。 E.g。

android {
    defaultConfig {
        minifyEnabled true
        consumerProguardFiles 'proguard-rules.pro'
    }
    ...
}

proguardFiles适用于应用程序模块，而不适用于库模块。

答案 2 :(得分：0)

您获得的初始错误类似于KotlinReflectionInternalError when attempting to create an adapter for a data class中描述的错误，可以通过在ProGuard规则中添加以下内容来解决：

-keepclassmembers class kotlin.Metadata {
   public <methods>;
}

对于第二个错误，请将此规则添加到ProGuard：

-keep class kotlin.reflect.jvm.internal.** { *; }
