You need to find the config file for the AVD that you have created.

In my case, I'm running the AVD on Ubuntu, so this is where I found the config file.

~/.android/avd/emulator.avd/config.ini

"emulator" was the name I provided when I created the AVD, so the directory name will depend on what you provided.

The following is what is inside the config.ini file:

hw.lcd.density=240
skin.name=WVGA800
skin.path=platforms/android-8/skins/WVGA800
hw.cpu.arch=arm
abi.type=armeabi
vm.heapSize=64
hw.ramSize=1024
image.sysdir.1=platforms/android-8/images/

I increased my heap size from 24 to 64, and added the ram size parameter.

For the list of parameters you can add, refer to: Managing AVDs from the Command-line

You can change the default value of hw.ramSize in hardware.ini which you uses. For example, if you change the platforms/android-15/skins/**WVGA800**/hardware.ini to

hw.lcd.density=240
vm.heapSize=48
hw.ramSize=1024

Then you can create an avd that has 1024M of ram by using:

android create avd -f -t <target> -s **WVGA800** -n test_avd
