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

请添加图片描述

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

在这里插入图片描述

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 | devapp1 {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 "${defaultConfig.applicationId}.dev"// 自动生成@string/app_name为demo 把AndroidManifest.xml中的 android:label="demo"替换成 android:label="@string/app_name"// resValue "string", "app_name", "jh-demo1"// 定义app_icon字段，在AndroidManifest.xml文件中用到manifestPlaceholders = [app_name: "jh-demo1",app_icon: "@mipmap/ic_launcher",]}// app2 | prodapp2 {dimension "default"// applicationId "com.jh.demo2"applicationId "${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：

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

替换后：

        <applicationandroid: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 --releaseflutter 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 packagepackage: name='com.jh.jh_flutter_demo.dev' versionCode='6' versionName='3.16.0'aapt dump badging D:\apk\xxx.apk安裝apkadb 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

请添加图片描述

  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 translateddisable 'InvalidPackage'}
