Hi
can anyone tell me how to use activitycreator in window to generate android project structure.

Google's own webpage

c:\AndroidSDK\Tools\> activitycreator --out myProject your.package.name.ActivityName


--out myProject will create the project in that folder (myProject for my example).
your.package.name.ActivityName will result in an activity called 'ActivityName' under a package called 'your.package.name'
