My apologies if this is a stupid newbie question...
I'm using Eclipse (Helios release) and have the Android SDK all configured as per the developer.android.com recommendations. I can create and run new projects without any problem but I can't import archived project code samples (found on the web etc.) using Import > Existing Projects Into Workspace.
Importing a zip creates a project but it doesn't create it as an Android project and the console displays the error: "Project has no default.properties file! Edit the project properties to set one."
I've tried going into the project Properties but as soon as I click on 'Android' in the properties tree a pop-up appears saying "Could Not Accept Changes: The currently displayed page contains invalid values"
But if I do this on one of my own projects I have no such error, and I'm able to change things such as the Android Platform/API level. I'm also able to archive my own projects (using export) and import them again without any problems... nut not other people's archives! Am I being really stupid?
Any help would be really appreciated!
