使用VS code 和WSL开发android

kiah Android开发, C/C++技巧, Linux技巧 九月 24, 2020

目前开发主要时在Windows+AS开发不过有些部署相关的工作还是需要linux环境，所以重复之前wsl的挫折，又开始折腾wsl2.之前使用wsl 有报出比较多的问题，比如memory容易爆掉， 文件file mode在挂在盘上会发生变化导致git使用不方便等。建议可以使用下wsl2或者是使用无界面virtualbox， 透过ssh链接

vs in virtual box

https://code.visualstudio.com/docs/remote/ssh

remote ssh

设置ssh 的pub key，可以免掉输入密码的麻烦

其它参考wsl

WSL

install wsl

Enable the WSL subsystem

  • Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux

download the release archive and run command with install
refer to https://damsteen.nl/blog/2018/08/29/installing-wsl-manually-on-non-system-drive
download the ubuntu release archive https://aka.ms/wsl-ubuntu-1804
query the registered ubuntu release
wslconfig.exe /l all
uninstall wsl
wsconfig.exe
wslconfig.exe /l all

C:\Users\users>wslconfig.exe /l /all
适用于 Linux 的 Windows 子系统:
Ubuntu-18.04 (默认)`
wslconfig.exe /u Ubuntu-18.04

install visual code

visual code with wsl

visual code with cmake

sudo apt install cmake
install plugin(you can refer to the article in step 1)

Android KIT

https://developer.android.com/studio/projects/install-ndk

install Android SDK

cd /home/<user>/
sudo apt-get install unzip
wget https://dl.google.com/android/repository/sdk-tools-linux-4333796.zip
unzip sdk-tools-linux-4333796.zip -d Android
rm sdk-tools-linux-4333796.zip
sudo apt-get install -y lib32z1 openjdk-8-jdk
export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
export PATH=$PATH:$JAVA_HOME/bin
printf "\n\nexport JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64\nexport PATH=\$PATH:\$JAVA_HOME/bin" >> ~/.bashrc
cd Android/tools/bin
./sdkmanager "platform-tools" "platforms;android-27" "build-tools;30.0.0-rc2"
export ANDROID_HOME=/home/<user>/Android
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/platform-tools
printf "\n\nexport ANDROID_HOME=/home/<user>/Android\nexport PATH=\$PATH:\$ANDROID_HOME/tools\nexport PATH=\$PATH:\$ANDROID_HOME/platform-tools" >> ~/.bashrc
android update sdk --no-ui
sudo apt-get install gradle
gradle -v
adb start-server
install ndk
kiah@CD-DZ0200879:~/android/tools/bin$ ./sdkmanager ndk;17.2.4988734
install cmake

verify your IDE and wsl

    ]
}

限制WSL 内存使用

vmmem 爆host 内存解法
在C:\Users\%Username% 下面，创建一个.wslconfig 文件，文件中写以下内容

[wsl2]
memory=4GB # Limits VM memory in WSL 2 to 4 GB
swap=0
localhostForwarding=true

其它
