How to include a proguard configuration in my Android library (AAR)

Question

Android libraries, per the AAR file spec, includes a \'proguard.txt\' file. My understanding is that this file declares how the library correctly can be obfuscated and mini

Answer 1

In your Gradle file's default configuration closure, specify your Proguard file with consumerProguardFiles instead of proguardFiles. For example:

defaultConfig {
    consumerProguardFiles 'proguard.txt'
}

Answer 2

If you create library you can disable proguard and provide a consumerProguardFiles in you build.gradle which will be used by consumer project which resolve it

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

    buildTypes {
        release {
            minifyEnabled false
        }
    }
    //...
}

But if you should enable proguard, for example, because you want distribute your library as archive - you are able to use the next possibility:

android {

    buildTypes {
        release {
            minifyEnabled true
            proguardFiles 'proguard-rules.pro'
        }
    }
    //...
}
