how to create android emulator in command line with options?

Question

I want to create emulator in command line with some options, like hw.mainKeys = false. I need it to be an shell script so can run on automation test,however here I could not find a place to set those values.

android create avd 

do not have a place to specify those options.

One alternative is create a 'platform' type avd, however, the shell is a interactive shell that is great for human but hard for script

Android 4.1 is a basic Android platform.
Do you wish to create a custom hardware profile [no]yes 

Name of the AVD being run: 
avd.name [<build>]:

Are there some tools I can just pass options as parameters, like --hw.mainKeys false ?

Answer 1

You can create text file config.ini with desired parameters

hw.lcd.density=252
sdcard.size=32M
skin.name=NEXUS-ONE
skin.path=platforms/android-10/skins/NEXUS-ONE
hw.cpu.arch=arm
hw.keyboard.lid=no
abi.type=armeabi
hw.keyboard=no
vm.heapSize=24
hw.ramSize=256
image.sysdir.1=platforms/android-10/images/

See official documentation here

From android --help create avd:

   Usage:
   android [global options] create avd [action options]
   Global options:
  -s --silent     : Silent mode, shows errors only.
  -v --verbose    : Verbose mode, shows errors, warnings and all messages.
     --clear-cache: Clear the SDK Manager repository manifest cache.
  -h --help       : Help on a specific command.
