How Do I?
This page is meant to answer quick questions on how to do many small things in Codename One by example, please use the discussion forum to ask for a particular sample although we will generally only post relatively simple stuff that can be covered briefly. For a complete training solution check out our training section.
Create a Basic Hello World Application & Send It To My Device Using NetBeans
Note: There is a NetBeans bug that occurs in all versions where sometimes a file that was correctly created into the src directory just refuses to appear in the netbeans file explorer so you won't see the theme.res even though it is there. Restarting NetBeans solves the issue, its generally hard to reproduce consistently so we weren't able to nail down a workaround for this.
