Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

node-avd

npm (tag) npm type definitions tested with jest styled with prettier npm collaborators

介绍

如果你想使用Android Emulator,但是不想安装庞大的Android Studio,或者觉得安装的过程太繁琐,那么这个包可以帮到你。

node-avd可以通过几个简单的命令就可以帮助你安装好avd需要的依赖环境并启动模拟器,当前也提供了一些方法来管理模拟器。

准备工作

提前准备好 java 环境,参考 oracle java

安装

npm i -g node-avd

在 linux 上要加 sudo 来执行

命令行使用简单示例

  1. 在命令行中进入一个空的文件夹,例如:cd ~/avd
  2. node-avd init -n test :初始化并创建一个名为 test 的模拟器
  3. node-avd start test : 启动模拟器 test

API 使用简单示例

import { Avd, getPlatform } from 'node-avd';

const Example = {
  exampleCmdlineToolsUri: `https://dl.google.com/android/repository/commandlinetools-${getPlatform()}-8512546_latest.zip`,
  exampleSdkHome: `${process.cwd()}`, // any empty dir
  exampleSystemImage: 'system-images;android-28;default;x86', // a system will be use to avd,can find list in node-avd -ls
  exampleAvdName: `car` //the name of avd
};


async function init() {
  /** 1. new Avd()  */
  const avd = new Avd(Example.exampleSdkHome);
  /** 2. install android commandline tools */
  await avd.installCmdlineTools(Example.exampleCmdlineToolsUri);
  /** 3. install a system image */
  await avd.installSystemImage(Example.exampleSystemImage);
  /** 4. create an avd */
  await avd.createAvd({ name: Example.exampleAvdName, system: Example.exampleSystemImage });
  /** 5. start an avd */
  avd.startAvd(Example.exampleAvdName, false /* set cold start*/);
}
init();

其他

启动模拟器时报错

若你启动时遇到如下问题: HAXM error 可以使用 node-avd HAXM命令来帮助你,然后再重新启动模拟器

设置模拟器硬件配置

若你想修改模拟器的硬件配置,例如屏幕尺寸,你可以使用node-avd -la得到模拟器的目录,打开目录找到一个 config.ini 文件,修改对应值后重启模拟器即可 例如修改模拟器的屏幕尺寸:

  1. 通过node-avd -la得到模拟器的目录 1

  2. 打开这个文件夹找到 config.ini 文件 2

  3. 使用任意文本编辑器修改其中关于屏幕尺寸的部分(搜索 lcd 字段可以快速定位屏幕尺寸部分) 3 例如修改屏幕的长和宽:

    hw.lcd.height = 720
    hw.lcd.width = 1790
