System images do not show up in SDK Manager When I try to create a new AVD, I get the error that there is no system image available. A quick search on the internet tells me that I should download it via the SDK manager, but no system images are showing up in the list.

As well, I get an error that it cannot fetch information from two .xml files. Does this have anything to do with the system images?
There may be the proxy problem. Go to the option under tools and enter the Http proxy and port no.
