java - "cannot be resolved or is not a field" -- android -- vogella tutorial -


i did tutorial here: http://www.vogella.com/articles/androidsqlite/article.html#todo

  @override   protected void oncreate(bundle bundle) {     super.oncreate(bundle);     setcontentview(r.layout.todo_edit);

in last line eclipse underlines todo_edit , says: todo_edit cannot resolved or not field

todo_edit in layout folder.

it not start capital letter

i have not imported android.r

i dont error might be. ( again: not own code, made professionals )

any ideas ?

you must check xml files there error

if not building r.java means there error in of xml or manifest file check wont build until

  1. check recent change did xml

  2. you can remove , re-add recent added/changed xml file
