命令行搭建flutter-android编译环境

• linux 安装

docker run -itd --name=flutter \
--network=host \
-v ($pwd):$(pwd) \
registry.cn-hangzhou.aliyuncs.com/jcleng/wrt-ubuntu:20.04

docker exec -it flutter bash

# flutter sdk
git clone -b 3.27.4 --depth=1 https://mirrors.tuna.tsinghua.edu.cn/git/flutter-sdk.git
git clone -b 3.27.4 --depth=1 https://github.akams.cn/https://github.com/flutter/flutter.git

apt-get update && apt-get install curl iputils-ping -y

# 临时使用commandlinetools获取sdkmanager https://androidsdkmanager.azurewebsites.net/cmdline-tools.html

# 使用adb进行配对
adb pair 192.168.195.198:35047
adb connect 192.168.195.198:43015


# 创建项目
flutter create fdemo
cd fdemo/android
# 换腾讯云
vi gradle/wrapper/gradle-wrapper.properties

# 使用代理, 以及修改 ~/.gradle/gradle.properties 的代理设置
export http_proxy=http://192.168.2.114:7892
export https_proxy=http://192.168.2.114:7892

touch ~/.gradle/gradle.properties

# 构建测试
flutter pub get
# 编辑环境
code android/local.properties

sdk.dir=/home/wb/g/ANDROID_HOME/
flutter.sdk=/home/wb/g/flutter-sdk/
flutter.buildMode=debug
flutter.versionName=1.0.0

# 构建测试
./gradlew assembleDebug

# 指定设备运行
flutter devices
flutter run -d 21091116C

• vscode连接进去

# 用户端vscode安装:
ms-vscode-remote.remote-ssh

# 服务端安装:
ms-vscode-remote.remote-containers
ms-azuretools.vscode-docker
# 设置扩展的 docker path

# 容器内安装
Dart-Code.flutter

# 然后打开服务端[docker]找到刚刚的容器[附加 VSCODE]

code /etc/profile
# 最前面添加

export PATH=$PATH:$work_path/cmdline-tools/bin/:$work_path/flutter-sdk/bin/:$work_path/platform-tools
export ANDROID_HOME=$work_path/ANDROID_HOME
export JAVA_HOME=$work_path/JAVA_HOME/jdk-17/

# export http_proxy=http://192.168.2.114:7892

• 或者换项目的镜像源

主要是 android/build.gradle 的 allprojects.repositories 加了之后还有加 allprojects.buildscript.repositories
# 参考:
https://framagit.org/jcleng/flutter_stp/-/blob/master/android/build.gradle?ref_type=heads#L8

# android/build.gradle
// google()
// mavenCentral()
maven { url "https://maven.aliyun.com/repository/central/" }
maven { url "https://maven.aliyun.com/repository/public/" }
maven { url "https://maven.aliyun.com/repository/google/" }
maven { url "https://maven.aliyun.com/repository/gradle-plugin/" }
mavenCentral()

# android/settings.gradle
// google()
// mavenCentral()
// gradlePluginPortal()
maven { url "https://maven.aliyun.com/repository/central/" }
maven { url "https://maven.aliyun.com/repository/public/" }
maven { url "https://maven.aliyun.com/repository/google/" }
maven { url "https://maven.aliyun.com/repository/gradle-plugin/" }
mavenCentral()

• linux使用容器开发技巧

# docker映射x11和flutter
# 再使用vscode进到容器开发

• ~/.gradle/gradle.properties

# gradle设置超时时间
# Set the socket timeout to 5 minutes (good for proxies)
systemProp.org.gradle.internal.http.socketTimeout=300000
 # the number of retries (initial included) (default 3)
systemProp.org.gradle.internal.repository.max.retries=10
 # the initial time before retrying, in milliseconds (default 125)
systemProp.org.gradle.internal.repository.initial.backoff=500
systemProp.org.gradle.internal.http.connectionTimeout=300000

• run.sh
