Please read through all of the following tutorials, while I have endeavoured to make CAMdroid 2D simple and straight forward to use as possible, the small size of a phones screen (the target device) has made some features more cryptic than I would like, many buttons have dual use and some standard Android interface features have been coerced into doing something else!
