flutter开发实战-实现多渠道打包及友盟统计(亲测有效)

最近开发过程中,需要引入友盟进行统计服务。友盟统计还需要区分不同渠道的打开应用的情况,所以需要处理多渠道打包的问题。

一、引入友盟统计

在工程的pubspec.yaml中引入插件

  // 在工程 pubspec.yaml 中加入 
  dependencies:
     umeng_common_sdk: ^1.2.3
    

导入及调用初始化友盟

import 'package:umeng_common_sdk/umeng_common_sdk.dart';
    

调用友盟统计

@override
  void initState() {
    super.initState();
    initPlatformState();
    UmengCommonSdk.initCommon('5e3f96f3cb23d2a070000048', '5e3f96f3cb23d2a070000048', 'Umeng');
    UmengCommonSdk.setPageCollectionModeManual();
  }
    

这里需要填写channel渠道名后续我们需要根据打包的渠道来设置。

二、flutter代码中获取渠道

Flutter命令工具增加了自定义参数的功能 --dart-define,可以用这个命令参数在打包或运行 App 时设置参数。

如:

flutter run --dart-define=CHANNEL=YYB
    

在lib/main.dart中定义变量配置,可以方便调用

/// 定义环境变量配置
class EnvironmentConfig {
  static const CHANNEL = String.fromEnvironment('CHANNEL');
}
    

在需要的地方调用获取渠道名

  String currentChannel = "";

  @override
  void initState() {
    // TODO: implement initState
    super.initState();

    // 获取CHANNEL 参数值
    String channel = EnvironmentConfig.CHANNEL;
    print("channel:${channel}");
    currentChannel = channel;
    setState(() {});
  }
    

显示渠道名

            Container(
              height: 136,
              width: 300,
              color: Colors.lightGreen,
              alignment: Alignment.center,
              child: Text(
                '当前渠道:${currentChannel}',
                style: TextStyle(fontSize: 12, color: Colors.white),
              ),
            ),
    

最终获得渠道显示效果图如下

在这里插入图片描述

三、android中gradle配置

我们需要在android/app/build.gradle中添加一下配置


/// 获取渠道参数使用,这里设置一下默认值
def dartEnvironmentVariables = [
        CHANNEL: 'guanfang-app',
]

if (project.hasProperty('dart-defines')) {
    dartEnvironmentVariables = dartEnvironmentVariables + project.property('dart-defines')
            .split(',')
            .collectEntries { entry ->
                def pair = new String(entry.decodeBase64(), 'UTF-8').split('=')
                [(pair.first()): pair.last()]
            }
}
    

在输出的apk中,添加对应渠道名,在android一下${dartEnvironmentVariables.CHANNEL}进行区分不同渠道的apk名称。

ext {
    publishName = 'AppDemoLab'
}

android {
    android.applicationVariants.all {variant ->
        variant.outputs.all {
            def buildTime = new Date().format('yyyyMMddHHmm')
            outputFileName = "${project.publishName}_${variant.versionName}_${variant.versionCode}_${buildTime}_${variant.buildType.name}_${dartEnvironmentVariables.CHANNEL}.apk"
        }
    }
}
    

打包与测试命令

# 调试例子1:设置渠道为应用宝。
flutter run --dart-define=CHANNEL=YYB

#打包例子1:打包应用宝渠道包
flutter build apk --dart-define=CHANNEL=YYB
    

可以是多个–dart-define,如:

#打包例子2:打包应用宝渠道包,DEBUG参数是Y
flutter build apk --dart-define=CHANNEL=YYB --dart-define=DEBUG=Y
    

四、apk.sh多渠道打包脚本

在脚本中定义了渠道channels=(YYB HUAWEI MI OPPO VIVO)

在工程目录下创建shell目录,将apk.sh放到shell目录下。
在工程目录下创建prod目录,prod目录下创建apk目录,用于存放打包的渠道apk文件

apk.sh多渠道打包脚本如下

#!/bin/sh

#---------------------请修改渠道数组----------------#
channels=(YYB HUAWEI MI OPPO VIVO)

#当前工程绝对路径
project_path=$(pwd)

#安卓包product文件夹路径
prod_path=${project_path}/prod/apk/
#Flutter打包生成的最初地址
release_path=${project_path}/build/app/outputs/apk/release/

clean_tips="执行flutter clean(默认:n) [ y/n ]"
echo $clean_tips
read  -t 5 is_clean
if [  ! -n "${is_clean}" ];then
	is_clean="n"
fi
while([[ $is_clean != "y" ]] && [[ $is_clean != "n" ]])
do
  echo "错误!只能输入[ y/n ] !!!"
  echo $clean_tips
  read is_clean
done

tips="请输入选择渠道(默认:0) [ ALL: 0 "
c_length=${#channels[@]};
for(( i=0; i<$c_length; i++)) do
  if (($i < $c_length-1 )); then
    tips="${tips}${channels[i]}: $((i+1)) "
  else
    tips="${tips}${channels[i]}: $((i+1)) ]"
  fi
done;

echo $tips
read  -t 5 number
if [  ! -n "${number}" ];then
	number=0
fi
while(( $number < "0" || $number > $c_length ))
do
  echo "错误!只能输入0到${c_length} !!!"
  echo $tips
  read number
done

#如果有product/apk文件夹则删除,然后再创建一个空文件夹
if [ -d ${prod_path} ]; then
  rm -rf ${prod_path}
fi
#创建目录
mkdir -p ${prod_path}

if [ ${is_clean} = "y" ];then
  echo "=============== 开始清理 ==============="
	flutter clean
fi

if (($number == 0 )); then
  echo "=============== 开始构建:全部渠道包 ==============="
  for(( i=0;i<${c_length};i++)) do
    echo "正在构建:${channels[$i]} 渠道包"
    flutter build apk --no-shrink --dart-define=CHANNEL=${channels[$i]}
    cp -R ${release_path}*.apk ${prod_path}
  done;
else
  echo "=============== 正在构建:${channels[$((number-1))]} 渠道包 ==============="
  flutter build apk --no-shrink --dart-define=CHANNEL=${channels[$((number-1))]}
  cp -R ${release_path}*.apk ${prod_path}
fi

#判断apk目录下是否有文件
if [ "$(ls -A $prod_path)" ]; then
  echo "=============== APK包已导出:$prod_path ==============="
  open $prod_path
else
  echo '=============== APK包导出失败 ==============='
  exit 1
fi
exit 0
    

查看脚本可以看出

控制是否执行flutter clean
输入是全部渠道打包
打包后的apk拷贝到prod/apk文件夹下。

通过cd切换到shell目录下,执行apk.sh脚本进行多渠道打包

./shell/papk.sh
    

在prod/apk目录下,可以看到打包的apk

五、更改友盟渠道

在文中,使用友盟时候,需要传递渠道名,我们通过EnvironmentConfig.CHANNEL拿到渠道名后作为参数传给友盟。
友盟即可根据渠道进行统计。

六、附录(完整的gradle配置)

android/build.gradle配置如下

buildscript {
    ext.kotlin_version = '1.7.10'
    repositories {
        maven { url "https://maven.aliyun.com/repository/google" }
        maven { url "https://maven.aliyun.com/repository/central" }
        maven { url "https://maven.aliyun.com/repository/jcenter" }
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:7.2.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

allprojects {
    repositories {
        maven { url "https://maven.aliyun.com/repository/google" }
        maven { url "https://maven.aliyun.com/repository/central" }
        maven { url "https://maven.aliyun.com/repository/jcenter" }
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

    

android/app/build.gradle配置如下

def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
    flutterVersionCode = '1'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    flutterVersionName = '1.0'
}

def keystoreProperties = new Properties()
def keystorePropertiesFile = rootProject.file('key.properties')
if (keystorePropertiesFile.exists()) {
    keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
}

/// 获取渠道参数使用,这里设置一下默认值
def dartEnvironmentVariables = [
        CHANNEL: 'GuanFang',
]

if (project.hasProperty('dart-defines')) {
    dartEnvironmentVariables = dartEnvironmentVariables + project.property('dart-defines')
            .split(',')
            .collectEntries { entry ->
                def pair = new String(entry.decodeBase64(), 'UTF-8').split('=')
                [(pair.first()): pair.last()]
            }
}

ext {
    publishName = 'AppDemoLab'
}

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

android {
    compileSdkVersion 34
    ndkVersion flutter.ndkVersion

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.example.flutter_app_demolab"
        // You can update the following values to match your application needs.
        // For more information, see: https://docs.flutter.dev/deployment/android#reviewing-the-gradle-build-configuration.
        minSdkVersion 21
        targetSdkVersion flutter.targetSdkVersion
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName

        ndk {
            abiFilters "armeabi-v7a", "arm64-v8a"
        }
    }

    buildTypes {
        release {
            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.debug
        }
    }

    android.applicationVariants.all {variant ->
        variant.outputs.all {
            def buildTime = new Date().format('yyyyMMddHHmm')
            outputFileName = "${project.publishName}_${variant.versionName}_${variant.versionCode}_${buildTime}_${variant.buildType.name}_${dartEnvironmentVariables.CHANNEL}.apk"
        }
    }
}

flutter {
    source '../..'
}
