您可以使用构建变体来达到您的目的：

• 构建分级 *

android{

    defaultConfig {
        applicationId "com.example.test"
      //...
    }
    flavorDimensions "mode"
    productFlavors {

        paid {
            applicationIdSuffix ".paid"
            flavorDimensions "mode"
        }

        free {
            applicationIdSuffix ".free"
            flavorDimensions "mode"
        }
    }
}

• 机器人清单.xml：*

<manifest 

    ...
        <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">

    ...

    </application>

</manifest>

这样，您就可以在项目中创建两种类型的sourceSet，如下所示：例如，您可以在string.xml中创建应用名称字符串，并在自定义免费sourceSet的mipmap中添加新的应用图标

除了创建两个sourceSet（如下图所示）之外，您还可以使用manifestPlaceholders，并且不需要创建任何其他sourceSet：

• 构建分级 *

android{
    defaultConfig {
        applicationId "com.example.test"
      //...
    }
    flavorDimensions "mode"
    productFlavors {

        paid {
            applicationIdSuffix ".paid"
            flavorDimensions "mode"
            manifestPlaceholders = [
                 "app_icon": "@mipmap/icon_paid",
                 "app_name": "paid~~~",
            ]
        }

        free {
            applicationIdSuffix ".free"
            flavorDimensions "mode"
            manifestPlaceholders = [
                 "app_icon": "@mipmap/icon_free",
                 "app_name": "free~~~",
            ]
        }
    }
}

• 机器人清单.xml*

<manifest 

    ...
        <application
        android:allowBackup="true"
        android:icon="${app_icon}"
        android:label="${app_name}"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">

    ...

    </application>

</manifest>
