Can't change the Ram size in AVD manager android studio

If you create an AVD with "Recommended" system image then you can't change the "Memory and Storage" parameters neither when you create AVD nor when you edit your AVD.

Solution:

Look for your avd folder, then look for the folder of the image you want to change and edit the config.ini. change the value of
