Fix Android Error - Invalid Command-line Parameter: Files

Posted On Wed Jul 13, 2011 By mel In General Errors Forums And Topics Discussions You Find On The Web Forums

hi everyone, just wanted to share something or better yet a problem i had with my installation of my android sdk. when i was creating the hello world from the google website:

http://developer.android.com/resources/tutorials/hello-world.html

when i completed the 'Run the Application' step, i got this error message on the console tab.

[2011-07-13 16:22:48 - Emulator] invalid command-line parameter: Files.
[2011-07-13 16:22:48 - Emulator] Hint: use '@foo' to launch a virtual device named 'foo'.
[2011-07-13 16:22:48 - Emulator] please use -help for more information

the problem was that i have a 64bit windows 7 pc and the path for the SDK location was D:\Program Files (x86)\Android\android-sdk

so i needed to change the Program Files (x86) to D:\PROGRA~2\Android\android-sdk

if you have another OS like windows 7 32bit, you can use this website as preferences,

if you have windows XP for example:
change from:
C:\Program Files\Wallpaperama\Android\android-sdk
to
C:\PROGRA~1\Wallpaperama\Android\android-sdk

if you have something else where you installed your android SDK:
change from:
C:\Andoid Apps\Wallpaperama\Android\android-sdk
to
C:\ANDROID~1\Wallpaperama\Android\android-sdk

so basically, the problem is the spaces. there should not be any spaces in your SDK location

after i was able to fix the SDK location, i didnt get the error anymore

UPDATE: thank you for all your comments. i appreciate all the +1
i see that many of you are asking where do you make the changes... a picture is worth a thousand words, but a video is worth a million!!! so i made a short video how to make the changes

Thank u very (!) much.

PS: You dont have to rename the folder itself - just adjust the path within eclipse as shown in the picture.

Terry Sun Sep 18, 2011

The more general answer is to find the short path name in a DOS command window. Open a command prompt window (in the accessories menu), go to the root of the drive that your SDK is installed on, and type the following command.

cd /
dir /ad /x

It will show both the long name and the short name for the directories and files in that hard drive which is longer than 8 characters in length or has spaces in the name. Use the short name that represents the path to your SDK in place of the long name. If you have other subfolder names with long names in the path you may need to replace those as well.

Cheers
