When we upgraded to 2.11 emulators stopped working. Projects are configured to run an emulator with defined properties. Builds fail with the following:

emulator: ERROR: unknown skin name 'wvga800'

or whatever skin is selected in the project configuration. After poking around it seems the generated AVD's config.ini is the culprit:

skin.name=wvga800
skin.path=platformsandroid-15skinsWVGA800

compared to a similar AVD created manually:

skin.name=WVGA800
skin.path=platforms\android-15\skins\WVGA800

I can manually repair and correct the config, then launch the AVD, but Jenkins will overwrite the config with the next build and break it again. So the "Run emulator with properties" feature is useless.
