Question: I have been working on an application, which was running absolutely fine before i switched to another application. After few days when i came to work on my previous application, I am getting this particular error while launching the emulator for it. This error is as follows:

```
[2011-08-24 11:46:06 - Emulator] invalid command-line parameter: partition-size 1024.
[2011-08-24 11:46:06 - Emulator] Hint: use '@foo' to launch a virtual device named 'foo'.
[2011-08-24 11:46:06 - Emulator] please use -help for more information

```

What could possibly be the issue..??? Any help is appreciated.

Answer: 
Spaces may be contained in the installation path of Android SDK.

You may move it under a path with no space in it.

change the path of the SDK. put SDK directly in the drive ie. **"d:\Android\android-sdk-tools"**

note: make sure that there is no space in parent path
