Expo裸项目配置Android Flavor后安装dev版本报错求助

问题现象 #

配置Expo项目在Android上使用com.myapp（生产）和com.myapp.dev（开发）两个包名，执行构建命令后设备上成功安装了myapp-dev，但出现报错：

BUILD SUCCESSFUL in 4s
367 actionable tasks: 28 executed, 339 up-to-date
CommandError: No development build (com.myapp) for this project is installed. Please make and install a development build on the device first.

已做配置 #

1. android/app/build.gradle 配置 #

flavorDimensions "env"
productFlavors {
    development {
        dimension "env"
        applicationId "com.myapp.dev"
    }
    production {
        dimension "env"
        applicationId "com.myapp"
    }
}

2. android/app/src/development/AndroidManifest.xml #

<manifest xmlns:android="http://schemas.android.com/apk/res/android">
  <uses-permission android:name="android.permission.INTERNET"/>
  <!-- OPTIONAL PERMISSIONS, REMOVE WHATEVER YOU DO NOT NEED -->
  <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>
  <uses-permission android:name="android.permission.VIBRATE"/>
  <!-- These require runtime permissions on M -->
  <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
  <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
  <!-- END OPTIONAL PERMISSIONS -->

      </intent-filter>
    </activity>
    <activity android:name="com.facebook.react.devsupport.DevSettingsActivity" android:exported="false"/>
  </application>
</manifest>

3. android/app/src/development/res/values/strings.xml #

<resources>
    <string name="app_name">MyApp-Dev</string>
</resources>

4. app.config.js 配置 #

const isDev = process.env.APP_ENV === "development";

console.log(`Running in ${isDev ? "development" : "production"} env`);

export default {
  name: isDev ? "MyApp (Dev)" : "MyApp",
  slug: isDev ? "myapp-dev" : "myapp",
  version: "0.0.1",
  ios: {
    bundleIdentifier: isDev ? "com.myapp.dev" : "com.myapp",
  },
  android: {
    package: isDev ? "com.myapp.dev" : "com.myapp",
  },
  extra: {
    env: isDev ? "development" : "production",
  },
};

构建命令 #

"android:dev": "APP_ENV=development expo run:android --variant developmentRelease --no-build-cache"

问题原因及解决方案 #

1. 变体类型错误：Release构建不是开发构建 #

报错提示需要development build（开发构建），但你使用的是developmentRelease变体——这是生产环境的Release构建，不包含开发服务器连接所需的调试组件。

解决方法：将构建命令中的变体改为developmentDebug：

"android:dev": "APP_ENV=development expo run:android --variant developmentDebug --no-build-cache"

2. Expo未匹配到正确的包名 #

即使安装了com.myapp.dev的构建，Expo可能仍在尝试寻找默认的com.myapp包名。可以通过以下两种方式解决：

• 方式一：命令行指定包名
  在构建命令中添加--package com.myapp.dev参数，明确告诉Expo要连接的包：

  "android:dev": "APP_ENV=development expo run:android --variant developmentDebug --package com.myapp.dev --no-build-cache"
  

• 方式二：确保环境变量正确传递
  确保构建时APP_ENV=development环境变量正确生效，让Expo读取到并生成对应包名的配置：

  "android:dev": "export APP_ENV=development && expo run:android --variant developmentDebug --no-build-cache"
  

3. 验证gradle配置 #

确保productFlavors中的applicationId与app.config.js的android.package完全对应，避免拼写错误。同时确认flavorDimensions设置正确，没有其他冲突的gradle配置。
