Setup Android Emulator

[cvarjao]

Starting the Android Emulator from a command line

1. Create an Emulator/AVD (Android Virtual Device)
   See official docs on how to create an AVD
2. From the command prompt, find the Emulator/AVD you want to start

   $ emulator -list-avds 
      Pixel_4_API_29_-_gplay
      Pixel_4_API_29_2
      Pixel_4_API_30_-_gplay4demo
   

3. Start the emulator. Base on the command line above, let's start an emulator called "Pixel_4_API_30_-_gplay4demo"

   $ emulator -avd Pixel_4_API_30_-_gplay4demo -netdelay none -netspeed full
   

If you are running on Windows, you may need to provide a few extra parameters:

$ emulator -avd Pixel_4_API_30_-_gplay4demo -netdelay none -netspeed full -feature WindowsHypervisorPlatform -gpu host
