I am a newbie and like to do development on android. I have just downloaded, unzipped the SDK and installed it. When i type emulator on the command prompt i recieve the following error:

emaulator: ERROR: You did not provide the name of Android Virtual Device with the '-avd <name>' option. Read -help-avd for more information.

Please resolve and let me know what to do about it.

How do we create these AVDs and why do we need them?

Your help and guidelines would be appreciated.

I have read the tutorial and followed it. When i run the command: android create avd -n maxood -t 1
I get strange message for java usage like:

Usage: java [options] class [args...]
<to execute a class>.....
...................................................
..................................................
..................................................


Please help me out , why is that happening with me. Whats really wrong?

You get this error for every command?
So (for example) "android list targets" fail with the same (or a similar) error?

Anyway, looks like something is wrong with your java installation, so i would recommend to reinstall the latest java version as well as the android sdk.

Yes.I am getting this error for all the commands i am running from the command prompt. Please provide link of the latest version of JDK i need to install. I am going to reinstall the JDK and also the SDK as well.

I have the following on my system:

Operating System: Windows XP Service Pack 2
Processor: AMD Athlon(tm) 64x 2 Dual Core Processor
Memory: 1.87 GHz of RAM


Please let me know if any other pre-requisites i have to fulfill.

Thank you,
