Emulator uses too much ram

I've just installed the Android SDK and create my AVD, but I've got a problem. I'm on a Windows 7 x64, with an Intel i5 and 4GB RAM, so the emulator should run well.

But when I start it, on the windows task manager,开发者_JAVA技巧 I can see that it use more than 1GB of RAM! Is it possible?!

I tried to use snapshot, tried to set the device ram size to 1024 and tried to remove the SD emulation, as adviced in other question like this, but nothing changes.

Should I try to remove some SDK? Because I've installed a lot of them, for try to launch app in some different devices... but if them are going to slow me down, I'll just keep the 2.2 and 3.0 and no other else... Or maybe I shoud try to run in a x86 system?

Thanks!

Another thing that can be helpful (since I saw you were mentioning speed as well) is to lower the resolution of the emulator. At the Google IO 2011 session on the developer tools (video at http://www.google.com/events/io/2011/sessions/android-development-tools.html), they claimed that the reason the emulator is so slow is actually the graphics, not the CPU emulation, and that a lower resolution will help significantly. Hopefully things will speed up in the future, since they are working on hardware-accelerating the emulator! Obviously you're going to have to test on higher resolutions at some point, but you can try and get as much development done as possible on a lower setting.

You can assign the amount of RAM your emulator uses. Delete your current emulator and create a new one. If you're using eclipse to develop your app click on the Android button. Delete your current emulator and then create a new one. Under the heading SD Card you can set the size of your emulator.
