Question

好的，我有这个用例：

 override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        if (loginManager.isLoggedIn()) {
            if(BuildConfig.IS_FLAVOR_A){
                ActivityA.startActivity(this)
            } else if(BuildConfig.IS_FLAVOR_B){
                ActivityB.startActivity(this)
            }
        } else {
            ActivityC.startActivity(this)
        }
        this.finish()
    }

BuildConfig.IS_FLAVOR_A

是productFlavors中的标志，用于标识风味。 ActivityB只在这里被引用，我希望Proguard能够移除ActivityB及其所有资源，但它不是。

buildTypes {
        release {
            minifyEnabled true
            shrinkResources = true
            signingConfig signingConfigs.APK_Release_Temp
            proguardFiles getDefaultProguardFile('proguard-android.txt'), '.../proguard-rules.pro'
        }

    }

缺少什么？我真的可以做到这一点吗？ Flavors编译时常量允许proguard删除未使用的代码，在这种情况下，ActivityB.startActivity(this)

您需要启用优化。为此，请改用此配置：

proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'),'.../proguard-rules.pro'
