Is 8gb RAM enough for android emulator?

1–1.5 gb will be consumed by most of your OS and processes running parallely. So with android studio basically you’ll see that 80–85% ram is being used if you have 4gb ram. In case of 8gb it’s more than enough. Ram is more into consideration if you want to run AVD i.e Virtual Emulator.
