我创建一个免费和付费版本，一个非常简单的应用程序，对于这个我使用的伟大productFlavors在Android摇篮插件功能。我理解的build.gradle文件应该如何进行配置，写它，所以我的构建选项;

I'm creating a very simple app with a free and paid version, for this I'm using the great productFlavors feature in the Android Gradle plugin. I understand how the build.gradle file should be configured and have written it so my build options are;

（如下所示）

buildTypes {
    release {
        runProguard false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        signingConfig signingConfigs.someconfig
    }
}
productFlavors {
    free {
        packageName "com.somepackagename.appfree"
    }
    paid {
        packageName "com.somepackagename.appPaid"
    }
}

基本上，所有我想要做的就是限制了一些功能，并添加AdMod的免费版本，我将如何做呢？难道我添加if-else语句在检查，看它是否是免费或付费的我主要的java类？或者我可以覆盖在免费的目录中的java类？我应该如何去这样做呢？

Basically, all I'm trying to do is restrict a few features and add AdMod to the free version, how would I do that? Do I add if-else statements in my main java classes that check to see if it's free or paid? or can I overwrite java classes in the free directory? How should I go about doing this?

推荐答案

可以连接在目录结构code的东西，例如：

You can encode things in the directory structure, e.g.:

src/
  main/                    # Common source and assets
    java/
    res/
    AndroidManifest.xml
  free/                    # Source and assets for the free flavour
    java/
    res/
    AndroidManifest.xml
  paid/                    # Source and assets for the paid flavour
    java/
    res/
    AndroidManifest.xml

的code和特定于一个版本或其他资产进入特定的目录。该清单被合并。您可以使用字段生成到 BuildConfig.java 的风味基地的if-else语句。
