Flutter - 安卓一次打包不同包名的apk

demo 地址: https://github.com/iotjin/jh_flutter_demo
代码不定时更新，请前往github查看最新代码

有时为了方便测试，同一个app需要在一个手机上装两个，直接改包名的话比较麻烦，这时可以通过添加flavor进行多维度打包，同一份代码可以设置不同的包名，app应用名称和应用图标

效果图

flutter 一键打出不同包名、应用名、版本名、签名、应用图标、版本号的安装包
Android Studio 一个工程打包多个不同包名的APK
Android Gradle —— flavorDimensions 与 productFlavors

配置

需要修改的文件有两个，一个是 android/app/build.gradle ，一个是 android/app/src/main/AndroidManifest.xml

productFlavors 配置

核心代码是在 build.gradle添加 productFlavors 配置

 flavorDimensions("default") // 定义一个维度，这个维度的名字叫default，和下面的productFlavors中的dimension "default"对应
    productFlavors {
        // app1 | dev
        app1 {
            dimension "default"
            // 设置applicationId（这里很重要，两个相同applicationId的apk不能同时安装在同一台Android手机中）
            // applicationId "com.jh.demo1"
            applicationId "${defaultConfig.applicationId}.dev"
            // 自动生成@string/app_name为demo 把AndroidManifest.xml中的 android:label="demo"替换成 android:label="@string/app_name"
            // resValue "string", "app_name", "jh-demo1"
            // 定义app_icon字段，在AndroidManifest.xml文件中用到
            manifestPlaceholders = [
                    app_name: "jh-demo1",
                    app_icon: "@mipmap/ic_launcher",
            ]
        }
        // app2 | prod
        app2 {
            dimension "default"
            // applicationId "com.jh.demo2"
            applicationId "${defaultConfig.applicationId}"
            // resValue "string", "app_name", "jh-demo2"
            manifestPlaceholders = [
                    app_name: "jh-demo2",
                    app_icon: "@mipmap/ic_launcher",
            ]
        }
    }

然后需要在 AndroidManifest.xml把 android:icon和android:label换成上面配置的app_name和app_icon
替换前：

    <application
        android:name="${applicationName}"
        android:icon="@mipmap/ic_launcher"
        android:label="jh_flutter_demo">

替换后：

        <application
            android:name="${applicationName}"
            android:icon="${app_icon}"
            android:label="${app_name}">

新的编译和打包命令

加入flavor 后，按原来的方式调试运行或者打包会报错

编译：

 flutter run --flavor app1 -t lib/main.dart

打包：

flutter build apk --flavor app1

添加flavor后编译报错
     需要在 编辑器顶部 Run/Debug Configuration 里面 build flavors 设置对应的flavor 如 app1

    编译运行命令
        flutter run --flavor app1 -t lib/main.dart

    打包命令
        flutter build apk --flavor app1 --release
        flutter build apk --release --flavor app1 --target-platform=android-arm64

    清除build缓存并且打包app1和app2的debug和release包
    flutter clean; flutter build apk --flavor app1 --debug; flutter build apk --flavor app1 --release; flutter build apk --flavor app2 --debug; flutter build apk --flavor app2 --release


     查看包名
       aapt dump badging D:\apk\xxx.apk | findstr package
       package: name='com.jh.jh_flutter_demo.dev' versionCode='6' versionName='3.16.0'

       aapt dump badging D:\apk\xxx.apk

     安裝apk
       adb install -r D:\apk\xxx.apk

点击run 按钮运行需要配置下图：

打包报错 可以添加下面代码

  lintOptions {
        //在打包Release版本的时候不进行检测
        checkReleaseBuilds false
        // 有报错也不会停止打包
        abortOnError false
        // 防止报错：Error: The resource string/app_name has not been translated
        disable 'InvalidPackage'
    }
