I'm either having a moment and missing something that should be obvious or there's an issue with the specific build I have that's causing an issue.

问题 The Xperia Z has a 1920x1080 screen. I need to develop an app which specifically targets this device but I currently don't have one. Thus I'd like to use an emulator with the same specifications but I can't find this screen size in the list of available devices in AVD Manager.
