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.

列出所有已安装的设备:emulator -list-avds

这将列出安装在Android Studio中的所有设备。

运行模拟器:emulator -avd device_name

例如，如果你在运行选项1中的命令后得到了Pixel_3a_API_30_x86，那么你运行模拟器的命令将是:emulator -avd Pixel_3a_API_30_x86

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。

亚行kill-server 亚洲开发银行启动服务器

在这里，你可以通过命令行查看执行该命令的选项:

emulator -avd avd_name [-option [value]] ... [-qemu args]

例如，我是这样使用它的:

emulator -avd ICS_ARM -wipe-data -no-boot-anim -cpu-delay 0

如果你已经有模拟器，并想使用使用命令，只需使用这一行代码

cd  C:\Users\yourUserName\AppData\Local\Android\Sdk\emulator | ./emulator -avd Pixel_5_API_32

回头谢谢我……
