使用dns帮助从命令行启动模拟器

模拟器程序位置:/Users/{{UserName}}/Library/Android/sdk/tools

检查现有avd:- 模拟器-list-avds 启动模拟器，设置dns /Users/{{UserName}}/Library/Android/sdk/tools/emulator -avd Pixel_API_26 -dns-server 8.8.8.8

我假设你已经构建了你的项目，只需要启动它，但你没有创建任何avd，必须使用命令行进行所有操作。你必须做以下事情。

Create a new virtual device (AVD) for the platform you need. If you have to use command line for creating your AVD, you can call android create avd -n <name> -t <targetID> where targetID is the API level you need. If you can use GUI, just type in android avd and it will launch the manager, where you can do the same. You can read more about AVD management through GUI and through command line. Run the AVD either by using command emulator -avd <name> or through previously launched GUI. Wait until the emulator fully loads, it takes some time. You can read about additional options here. Now you have to install the application to your AVD. Usually during development you just use the same Ant script you used to build the project, just select install target. However, you can install the application manually using command adb install <path-to-your-APK>. Now switch to emulator and launch your application like on any normal device, through the launcher. Or, as an alternative, you can use the following command: adb shell am start -a android.intent.action.MAIN -n <package>/<activity class>. For example: adb shell am start -a android.intent.action.MAIN -n org.sample.helloworld/org.sample.helloworld.HelloWorld. As a commenter suggested, you can also replace org.sample.helloworld.HelloWorld in the line above with just .HelloWorld, and it will work too.

对于一键式(BATCH文件)启动，这是我所做的:

从Android Studio -> Tools -> AVD Manager ->点击箭头向下，选择查看详细信息(对我来说是Pixel_2_API_28，所以下面相应地更改) 创建一个start.bat文件，并将以下内容放入其中:

c: cd C:\Program Files (x86)\Android\ android-sdk\emulator\ 模拟器-avd Pixel_2_API_28

解释:

第一行:对我来说是必要的，因为我从d启动它: 第二行:对我来说，没有使用工具\模拟器 第三行: 确保你用你的名字更改了AVD的名字 Pixel_2_API_28)

使用:

从命令行启动start.bat

我认为通过终端到达的最佳方式是:

cd ~/Library/Android/sdk/emulator

或者对于Windows:

cd %userProfile%\AppData\Local\Android\sdk\emulator

直接运行某个AVD:

./emulator -avd {AVD_NAME}

列出你的avd使用:

./emulator -list-avds

上可用的avd名称列表

android - avd。 SDK_PATH/工具/ emuls / netdelay no -netspeed full -avd “AVD_NAME”

在这里补充一下，每当你得到“错误:设备离线”意味着与模拟器和adb桥接器的连接由于模拟器启动所花费的时间而中断。

而不是重新启动模拟器在这一点上，尝试以下两个命令停止&启动adb桥再次。
