I want to edit or change the ram size while creating the android emulator from command line.
EX: While creating the emulator it's taking default ram size(Android SDK 4.0.3) 512 MB But I want to increase it to 768MB or decrease it to 256MB.
I want to change only Ram size. Because there is an option to change the Ram size.
Do you wish to create a custom hardware profile [no] Yes
If you entered yes, we need to provide so many things.
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
To answer the question in the title,
how to change the android emulator ram size from command line?
one has to use -memory option:
emulator -memory 768 -avd <AVD_NAME>
or
emulator -memory 256 -avd <AVD_NAME>
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
