dexguard 库无法加密类

Question

我尝试在我的 android 库项目中加密类。但我不能那样做。变量和字符串由 dexguard 更改，但 -encryptclasses 没有影响。我在构建输出中收到日志：

Warning: not encrypting kept class com.justexample.SomeClass1
Warning: not encrypting kept class com.justexample.SomeClass2
Warning: the configuration specifies to encrypt 2 classes that it keeps at the same time.
      Not encrypting those classes to avoid problems at runtime.
Note: inner class com.justexample.SomeClass1 is unencrypted, while its outer class is encrypted.
Note: inner class com.justexample.SomeClass2 is unencrypted, while its outer class is encrypted.
Note: one or more encrypted classes have unencrypted inner classes.

我的 dexguard-project.txt 是：

-verbose
-encryptstrings com.justexample.SomeClass1
-encryptclasses com.justexample.SomeClass1, com.justexample.SomeClass2

还有我的模块：

apply plugin: 'com.android.library'
apply plugin: 'dexguard'

android {
compileSdkVersion 25
defaultConfig {
    minSdkVersion 16
    targetSdkVersion 25
    versionCode 1
    versionName gitVersionName()
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFile getDefaultDexGuardFile('dexguard-library-release.pro')
        proguardFile 'dexguard-project.txt'

    }
}
sourceSets { main {
    assets.srcDirs = ['src/main/assets', 'src/androidTest/assets/']
} }
}

dependencies {
//my dependecies
}

您正在使用默认库配置：dexguard-library-release.pro，默认情况下会保留所有公共/受保护类。

您不能对保留的类进行加密。

要解决该问题，请使用激进配置：dexguard-library-release-aggressive.pro 并指定不应混淆的库的公共 API。

别忘了也使用 -repackageclasses com.mypackage.internal

将所有混淆的类移动到这个包中。
