Starting arm emulator gives "unknown option: - please use -help for a list of valid options"

Starting arm emulator gives "unknown option: -开发者_运维问答 please use -help for a list of valid options", but there does not seem to be anywhere to see or change the options being used. Does any-one know hows to get around this problem? Thanks.

I got the same error.

I reinstalled my SDK Manager again, same failure occurs. But there is no logging in AVD Manager so I can't trace the error.

If I start the AVD in the command line it works but the scale is not so pretty.

Also: CMD LINE START:

\tools\emulator.exe -avd HTC-TouchHD 

Works fine.

And start of SDK Manager shows

Is there any log-file in the system where I can find the executed command in SDK Manager (Win 7 Pro)?

!!! FOUND THE SOLUTION !!!

If a path is used with empty spaces the emulator couldn't start the AVD. I found the solution by copying my SDK-manager folder directly to main HDD. So my path is actually set to:

d:\sdk-manager

before:

"d:\android - tools\sdk-manager\"

How are you starting the emulator (In AVD Manager? From Eclipse?...)? Behind the scenes it's just running the command

<path-to-sdk>\tools\emulator.exe -avd emulatorname

The error you mentioned is thrown if there are invalid options. For example, the following:

<path-to-sdk>\tools\emulator.exe -avd emulatorname -wuioej

will throw the following error:

unknown option: -wuioej  
please use -help for a list of valid options

In your case it looks like there's just an extra '-' at the end for some reason, which is why I asked how you're starting the emulator.
