How to change the RAM size of the Android emulator from the command line?

Question

I want to edit or resize ram when creating android emulator from command line.

EX: when creating an emulator, it assumes the default spread size (Android SDK 4.0.3) 512 MB But I want to increase it to 768 MB or reduce it to 256 MB.

I want to change only the size of the Ram. Because it is possible to resize the frame.

Do you wish to create a custom hardware profile [no] Yes 

If you entered yes, we need to provide so many things.

Answer 1

You need to find the configuration file for the created AVD.

In my case, I run AVD on Ubuntu, so here I found the configuration file.

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

"emulator" is the name that I provided when creating the AVD, so the directory name will depend on what you provided.

The following is in 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 the heap size from 24 to 64 and added a ram size parameter.

For a list of options you can add, see Manage AVD from the command line.

To answer the question in the title,

how to resize android emulator buffer size from command line?

you need to use the -memory option:

 emulator -memory 768 -avd <AVD_NAME> 

or

 emulator -memory 256 -avd <AVD_NAME> 

Answer 3

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

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

Then you can create avd with 1024 M RAM using:

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