Migrating Your Project to Maven
As you may know, we are moving to Maven for our build tool. As part of this transition, we are moving towards a single Maven project structure, and away from separate structures for each IDE. This will be easier to maintain, and will also make it easier to collaborate on projects with other developers who use a different IDE (or no IDE at all). We have also introduced a online new tool for creating new app projects called Codename One initializr. Alternatively, you can create new projects using the cn1app-archetype (for App projects), and cn1lib-archetype for library projects. ...
Maven Project Structure
As a follow-up to our recent announcement about transitioning to Maven, this post provides an overview of the new project structure. Tip If you want to follow along with this tutorial, you can quickly generate a new project using Codename One intializr. The new project structure is based on the cn1app-archetype. You can see the basic file layout by looking at the archetype-resources directory of that project. Some Highlights: 1. This is a multi-module project with sub modules for each target platform. ...
You Can Now Build Android & iOS Apps Locally
Due to popular demand, we are officially providing local build support for iOS, Android and cross-platform JavaSE Desktop apps. No build server or Codename One account required. The Build Server has been a fundamental building block of Codename One from the very beginning. In the fractured world of mobile development where you need the latest Mac running the Latest Xcode to build for iOS, and the latest Windows running the latest Visual Studio to build for Windows, the build server reduced your system requirements to JDK 8 and an IDE. In general, this was a big win, and it makes mobile app development much more pleasant. ...
Moving to Maven
Codename One is migrating to Maven. This will simplify some aspects of our build process and update/dependency management. As the headline states, we’re moving to Maven, and leaving the ant-infested old build system behind. To be honest, I love using Ant. It is quick and dirty, and let’s me assemble ad-hoc build workflows with little effort. Migrating to Maven, at times, felt like strapping on a pair of cement boots. It is much more rigid than Ant, and much more opinionated. It’s the “Maven” way, or you’re in for a world of pain. ...
Data Processing in Codename One apps
The following recipes relate to data processing and conversion in Codename One apps. This includes parsing data like JSON, HTML and XML. Parsing HTML Problem You want to parse some HTML content into a data structure. You can’t simply use the XMLParser class because the content is not well-formed XML, but you would like to be able to work with the parsed document using the same tools (e.g. Result and Element.) Solution Use the HTMLParser class from the CN1HTMLParser cn1lib. It contains a simple API for parsing an HTML string into an Element, the same type of element that XMLParser returns. ...

Code Freeze for Codename One 7.0
At long last we’re entering code freeze for Codename One 7.0. This release cycle has been longer than it should have been because of many detours along the way. But finally if all goes according to plan, version 7.0 should be out next Friday. The code freeze won’t impact most of you as it’s mostly an artifact of our release cycle. We will have the regular Friday release but will only have critical reviewed commits during this week. Archived Comments This post was automatically migrated from the legacy Codename One blog. The original comments are preserved below for historical context. New discussion happens in the Discussion section. ...

A Junior Software Developer’s Journey at Codename One
Hello Codename One community, my name is Sergey Gerashenko. I’m a junior software developer at Codename One. My journey here began 3 months ago when I passed my first interview at Codename One and my first task was to learn Java within 2 weeks. Learning Java I knew a few programming languages like Python, C and C++ but was unfamiliar with Java or managed languages beforehand. Learning a completely new language in just two weeks seemed like an impossible task at first because it took me around five months to learn C++. ...
