Introducing Android Development with NetBeans
This wiki page described an old version of Android plugin and that's why I deleted the content here to avoid confussion. Read about current version at NBAndroid website.
If you really need to access old version of this document contributed by Amit Kumar Saha you can find it in history. Current maintainers of the plugin would be curious why you do this and you can contact them using one of the means described at contacts page.
if you need make some preprocessing of your code and text resources in android project then you can try to use the JCPreprocessor, it can be connected to NBAndroid project through ANT tasks.
