Android Studio – Correctly configure a release build – once per project or in all modules?

I’ve created my first Android project with two modules (:app and :additionalModule).

Now I want to create a release build with isMinifyEnabled = true and all these things. Do I have to configure that in each module (build.gradle.kts of each module) or only once in the project build.gradle.kts or maybe only once in my "main" (:app with MainActivity) module?

    Actual minification step is happening only in your application module.
    Library modules can provide required R8/ProGuard configuration using consumer-rules.pro file.

    You need to enable R8/ProGuard only in your :app module.
    Thus, you should keep isMinifyEnabled = true only in your :app module.

    The minifyEnabled flag is typically set in the build.gradle file of each module where you want to enable code shrinking and obfuscation (also known as minification).

    If you want to enable it for all modules in your project, you can set it in the build.gradle file of your app module (usually named app/build.gradle). This way, it will be applied to the entire project unless overridden in specific module build.gradle files.

    build.gradle.kts (:app)

    buildTypes {
    release {
        isMinifyEnabled = true
        proguardFiles(
            getDefaultProguardFile("proguard-android-optimize.txt"),
            "proguard-rules.pro"
        )
    }
}
