问题
The problem I am having is that when I run a FWVGA or WVGA sized emulator it sometimes runs at a MDPI size instead of HDPI. Here is an example with pictures

I create the AVD with the proper hw.lcd.density setting and screen size and it randomly does this. There doesn't seem to be a pattern. I used to be able to just delete the AVD and create it over again and it would fix itself for a while but now it's getting worse.
Does anyone have any ideas cause I posted on the Android Developer forum but all I got was other people saying they get the same problem.
回答1:
I get the same problem and find that it is often only solved by a reboot - of my PC rather than of the emulator. I've not needed to edit or recreate the AVD to solve the problem.
I think it might be related to unplugging my laptop from an external monitor and so changes the Windows display resolution but I haven't been able to regularly recreate the problem.
Since the same AVD image can work one day and not the next and the start working again after a reboot means that this must be a bug in the emulator rather than a problem with the configuration of the AVD.
Unfortunately, I don't know of any workarounds for the problem and as far as I can tell this hasn't been logged as a bug. (I haven't logged it myself since, as you say, it occurs randomly which makes it hard to fill in a decent bug report.)
