我有一个 RN 代码，我想在 Android 上拥有 2 种口味。这些口味的不同之处在于：
- ic_launcher 和可绘制
- 字符串
- 应用程序 ID
我在 app/build.gradle 文件中添加了产品风格，并为它们中的每一个添加了目录 res & AndroidManifest.xml。
我专门使用了这个库这部分。并成功完成了前 2 项。至于applicationId，每当我更改 productFlavors 部分中的 applicationId 字段时，它都会给我这个错误：
`react native error: activity class {mainactivity} does not exist.`
我使用这些命令来运行应用程序：
react-native run-android --variant flavortoneDebug
react-native run-android --variant flavorttwoDebug
我试图更改每个风味清单文件中的 package="" 字段，但它给了我这个错误：
Manifest merger failed : Overlay manifest:package attribute declared at
AndroidManifest.xml:2:11-38 value=(com.examle.flavorone)
has a different value=(com.examle.flavorone) declared in main manifest at AndroidManifest.xml:2:3-24
Suggestion: remove the overlay declaration at AndroidManifest.xml and place it in the build.gradle:
flavorName {
applicationId = "com.examle.flavorone"
}
目录按以下顺序排列：
-example
-android
---
-app
---
-src
-flavorone
-res
-AndroidManifest.xml
-flavortwo
-res
-AndroidManifest.xml
-main
-java
-res
-AndroidManifest.xml
-debug
-AndroidManifest.xml
-ios
-node_modules
-src

我搜索了其他库，也搜索了 stackoverflow 和其他网站，但找不到解决方案。
我真的很感激帮助。
