配置记录

使用Android Studio配置安卓sdk配置

这里安装Android Studio的过程就略过了，就把配置Android sdk的步骤记录下。

AS sdk设置

安装fluter并配置相关环境变量

// 安装flutter(我的电脑是intel芯，ARM架构请下载指定版本sdk)
$ wget -c https://storage.googleapis.com/flutter_infra_release/releases/stable/macos/flutter_macos_3.3.0-stable.zip
$ unzip flutter_macos_3.3.0-stable.zip
$ sudo mv flutter /usr/local/

// Android SDK环境变量设置：
$ cat ~/.zshrc
# ...(省略其他)
# Android SDK
export ANDROID_HOME=$HOME/Library/Android/sdk
export PATH=$PATH:$ANDROID_HOME/emulator
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/tools/bin
export PATH=$PATH:$ANDROID_HOME/platform-tools
# Flutter SDK
export PATH="$PATH:/usr/local/flutter/bin"
export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn


// 接受android sdk开发协议
$ flutter doctor --android-licenses

// 检测android的开发环境是否配置完整，
// 这里xcode会抛错，
// 没有关系，我们不需要打包ios。
$ flutter doctor

$ flutter create myflutter   // 创建flutter项目
$ cd myflutter
$ flutter run       // 本地运行

执行flutter doctor访问github.com网络连接超时？

$ flutter doctor
VersionCheckError: Command exited with code 128: git fetch __flutter_version_check__ stable
Standard error: fatal: unable to access 'https://github.com/flutter/flutter.git/': Failed to connect to github.com port
443: Operation timed out

解决办法：众所周知的原因，git环境变量增加一个代理即可。

$ cat ~/.gitconfig|grep -A 2 http
[http]
    proxy = socks5://[PROXY-HOST]:[PORT]

好了，截止现在，我们的flutter软件层面就配置完成了，接下来，我们配置下安卓真机环境如何连接。

真机联调

开启安卓手机开发者模式及USB授权

红米Note10-5G

各大厂商的安卓手机系统开发者模式开启方式可能略有不同，但是大体操作思路不会变化太大。等以上操作完成，就可以使用电脑远程连接操作手机了。

顺带这里说下，之前配置开发环境的时候踩到一个很无语的坑：因为数据线的问题（可能是那种只能充电无法数据传输），变更完上面的配置，adb一直无法识别到目标手机，被坑了半个小时，最后尝试换了一个靠谱的数据线问题解决。

远程连接目标设备

$ brew install android-platform-tools
$ brew install scrcpy

$ adb devices     // 查看已挂载的设备
List of devices attached
BDDIHMDYHY9DRK95	device

$ scrcpy -s BDDIHMDYHY9DRK95 // 远程连接目标设备
scrcpy 1.24 <https://github.com/Genymobile/scrcpy>
/usr/local/Cellar/scrcpy/1.24/share/scrcpy/scrcpy-server:...file pushed, 0 skipped. 12.7 MB/s (41159 bytes in 0.003s)
[server] INFO: Device: Xiaomi 21091116AC (Android 12)
2022-09-03 13:18:08.461 scrcpy[15418:1065753] INFO: Renderer: metal
2022-09-03 13:18:08.474 scrcpy[15418:1065753] INFO: Initial texture: 1080x2400

具体效果如下：

adb远程

好了，搞定。接下来就是畅快的玩转flutter吧。

+++ 20231215 更新flutter版本遇到的问题 +++

doctor_error

解决办法：

JDK(17.0.9)、Android Studio(2022版)的SDK都更新了一遍依然没有解决，最后祀出大招搞定 –> 重新升级安装了AS 2023版本，并下载安装sdk文件即可。

update_as_sdk_100 update_as_sdk_101
