android - React Native - 如何让 productFlavors 具有不同的 applicationIds？

我有一个 RN 代码，我想在 Android 上有 2 种口味。这些口味的不同之处在于:

ic_launcher & drawable

字符串

applicationId

我在 app/build.gradle 文件中添加了 product flavors，并为它们中的每一个添加了一个目录 res & AndroidManifest.xml。

我使用了这个 Library 专门的 this 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 flavor 的 list 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

main/AndroidManifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example">

<uses-permission android:name="android.permission.INTERNET" />

<application
 android:name=".MainApplication"

android:configChanges="keyboard|keyboardHidden|orientation|screenSize"

<intent-filter>
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
 <activity android:name="com.facebook.react.devsupport.DevSettingsActivity"
 />
 </application>

  </manifest>

flavorone/AndroidManifest.xml & flavortwo/AndroidManifest.xml

 <manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.example">
 <application
    android:supportsRtl="true">
 </application>
 </manifest>

这里是 app/build.gradle 代码:

我搜索过其他库，也搜索过 stackoverflow 和其他网站，但找不到解决方案。

我真的很感激你的帮助。

最佳答案

试试 react-native run-android --variant flavortoneDebug --appIdSuffix flavorone
