Additional confusion in some channel settings of Android Studio

productFlavors can be set to use different obfuscation for different channels.

The requirement this time is that the default obfuscation in the original project remains unchanged, but a few additional files are kept in a certain channel. At this time, you can configure as follows:

android {
    compileSdkVersion 28

    defaultConfig {
        // xxx

        // 配置此参数，方可将混淆文件打包进aar
        consumerProguardFiles 'consumer-rules.pro'
    }

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

    // 多版本打包
    productFlavors {
        xxx1{
            // 默认
        }
        xxx2{
            // 额外混淆
            proguardFile 'keepbuildinfo.pro'
        }
    }

    lintOptions {
        abortOnError false
    }

    sourceSets {
        main {
            jniLibs.srcDirs = ['libs']
        }
    }

    repositories {
        flatDir {
            dirs 'libs'
        }
    }
}

dependencies {

    // xxx
}

Additional obfuscation file keepbuildinfo.pro:

-keep class com.xxx.xxx.BuildInfo{*;}

at this time

keepbuildinfo.pro and proguard-rules.pro will take effect in the xxx2 channel at the same time
