android studio Error while waiting for device: The emulator process for AVD was killed

网上找了好多解决方案，最后发现是磁盘空间不足...
移动avd到其他盘，搞定。

Avalonia UI是一个.Net Core跨平台UI框架，支持多种操作系统：Windows、Linux、MacOS等。

一、跑个Hello World
1、安装Avalonia扩展
VS安装此扩展

https://marketplace.visualstudio.com/items?itemName=AvaloniaTeam.AvaloniaforVisualStudio

安装完后打开VS，创建一个Avalonia项目

创建完项目后生成一下即可在VS中实时预览

二、跑在Linux上试试

既然Avalonia支持跨平台，那在Windows上运行没问题后，把文件打包一下，发到Linux上试试能不能跑起来，我这里用得统信UOS

右击项目选择发布，设置一下发布文件

将发布文件复制到UOS中，双击HelloAvalonia文件添加权限即可直接打开，也可以终端中输入命令./HelloAvalonia打开
(UOS需要打开开发者权限)

调试时出现以下问题：

Error connecting to the service protocol: failed to connect to
http://127.0.0.1:56341/vQjFLT5wAX0=/

出现此问题是因为开启了代理，解决方法：

环境中配置本地地址不通过代理

export NO_PROXY=localhost,127.0.0.1

1、修改 $HOME/.zshrc文件

vim $HOME/.zshrc

2、添加以下内容

# Flutter路径
export PATH="$PATH:[Flutter路径]/flutter/bin"
# 国内镜像
export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
# 代理
export HTTP_PROXY=http://127.0.0.1:1080
export HTTPS_PROXY=http://127.0.0.1:1080

3、刷新

source $HOME/.zshrc

4、检查Flutter信息

flutter doctor

今天重装完Android Studio，启动模拟器时出现了以下问题

Emulator: dsound: Could not initialize DirectSoundCapture 15:37 Emulator: dsound: Reason: No sound driver is available for use, or the given GUID is not a valid DirectSound device ID 15:37 Emulator: dsound: Attempt to initialize voice without DirectSoundCapture object 15:37 Emulator: dsound: Attempt to initialize voice without DirectSoundCapture object 15:37 Emulator: audio: Failed to create voice goldfish_audio_in‘ 15:37 Emulator: D:\buildSoft\android-studio\sdk\emulator\qemu\windows-x86_64\qemu-system-i386.exe: warning: opening audio input failed 15:37 Emulator: dsound: Attempt to initialize voice without DirectSoundCapture object 15:37 Emulator: dsound: Attempt to initialize voice without DirectSoundCapture object 15:37 Emulator: audio: Failed to create voice adc’

找了好久终于找到了解决方法：

1、打开系统声音设置，打开声音控制面板

2、将录制里的立体声混音打开

3、重启模拟器，OK
