Codename One 3.8 is Live

We are thrilled to announce the release of Codename One 3.8. Codename One is an open source "Write Once Run Anywhere" mobile solution for Java developers!
This new release significantly refines the native look and feel of Codename One, it brings the GUI builder to a new level with styling support. It finally adds Mac OS appstore distribution support which means all the major appstores are now supported targets for Codename One applications.

Tutorial - What is Codename One

I published this video a while back but it was longer and a bit confusing (over 40 minutes). Since some developers watch it before getting into Codename One I thought it would be in order to streamline it into a more manageable length and transcribe the content like I did with the newer videos. I also cleaned it up a bit and the result is below.

Mac Appstore Builds & Device Farms

Steve has been pretty busy. We have new support for Mac Appstore builds as part of our desktop build process. That means you can build a signed Mac desktop app with Codename One which required a bit of work with previous releases. He also adapted our automated tests for Codename One so they would run on device farms and test against major versions of Android.

Codefreeze for 3.8

Codename One 3.8 should land one week from now and from later today we are effectively in code freeze. Please update to the release candidate of 3.8 tomorrow morning to help us track some last minute bugs and regressions. As is usually our process we will release updates as necessary with code reviews and next week we won't have the usual set of releases as we'll take some time off.

Tutorial - Working with Images and Densities

We had a lot of posts covering images, multi-image and density. It's one of the more challenging concepts to explain to developers coming from a desktop development background. Density is a simple concept to explain but the implications of it are sometimes counter-intuitive e.g. which device has higher density: Your phone or your 4k TV?

Pixel Perfect - Text Input (Part 2)

Last week we discussed the first part of working with text components and left some big tasks for this week. This week we'll try to address the remaining issues with text input and make it easier to construct UI's. This is crucial as we'll be going into code freeze soon and we need enough time to iron out the issues in the text input.

New Milestones and Features

We will enter code freeze for Codename One 3.8 next week and have a lot of things to clear off the table in order to get there!
The first order of business is that there will be no Codename One 3.9... Instead we will go right to 4.0 and switch to major version number update scheme only.

Tutorial - Creating Lists

Some of our how do I videos are so old it's embarrassing... This is especially true for some core concepts videos as they were some of the first ones we made. The worst part is that these are probably the most important videos we have as they are viewed by developers completely new to Codename One. We had two videos covering creations of lists and both of them used com.codename1.ui.List with the old GUI builder!

Pixel Perfect - Text Input

I started working on this post back in August and so much happened in between I just had to scrap the whole thing and start over again... I've discussed buttons before and now it's time for TextField & TextArea. But before we go into that lets take a moment to talk about the problems that arose from the last installment of pixel perfect.
