Your emulator is installed in the "Program Files" folder and eclipse is having trouble running it because of the space in the file name:
[2011-09-12 04:14:20 - Emulator] invalid command-line parameter: Files\Android\android-sdk\tools/emulator-arm.exe To fix it either re-install the SDK in a folder with no spaces in the name or use an "8.3" name for the location of the Android SDK in eclipse (I used C:\PROGRA~1\Android\android-sdk instead of C:\Program Files\Android\android-sdk) -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
