To create the HTML documentation, there are two options: 1) Standard Javadoc

• execute "ant -f javadoc.xml"
• the documentation will be created in the the "doc" folder 2) "DroidDoc"
• place the androidnfc directory (the directory where this README file is stored) in the "external" directory of the Android source code tree
• execute "mm androidnfc_library-docs"
• the documentation will be created in the ../../out/target/common/docs/androidnfc_library folder

Please note that the Javadoc is limited compared to the "DroidDoc" and currently does not contain overviews and guides (e.g. the NFC intent description).
