In recent versions of iOS Apple added the ability to distribute beta versions of your application to beta testers using tools they got from the testflight acquisition. We now support this with our crash protection pro feature, just use the build argument ios.testFligh...

This post we written by Steve Hannah, one of the newest additions to the Codename One team and a long time community contributor. This is the first in a series of posts about drawing graphics in Codename One. In this tutorial, we will create a rudimentary drawing app to demonstrate how to use the Shape API. Some Background Codename One has inclu...

I'll be speaking at Riga Dev Day next week and I've been working on a demo for the conference. Back in my teen years I bought the SoundBlaster 1.0 which was one of the first affordable soundcards for the PC. One of the killer demos that shipped with it was a silly command line AI psychoanalyst by the name of Dr. Sbaitso that would try to dish out a...

A recent issue in the issue tracker on the new iOS VM reminded me of a serious pet peeve and big design mistake in the Java Collections API, something that is just unfixable and wrong yet appears often in code from developers trying to be clever. If you have a collection and you want to convert it to an array you can do something like: Object[] m...

A Codename One community member Antonio Mannucci offered to release a gaming API that he created a while back. It took him some time but he finally delivered on his promise by releasing a cn1lib for simple 2D games in Codename One and a demo game to go with it. The project is still pretty rough in the sense that there is no real documentation or ...

Chen spent some time working on some Toolbar effects such as the rich title areas made popular by social network apps such as G+ & Twitter. The new Flickr demo in SVN now shows a really cool ability to fold the title bar as we scroll down and expand it when we scroll up. It also shows an image based title area that can fade out of view during scro...

We are closing 2014 which has been a pretty eventful year for us where we finally solidified Codename One, looking into 2015 we have a lot of great plans ahead! The new year seems like a great time to discuss some of our short/long term plans for Codename One as we move forward and our general thoughts. But first I'd like to open with the things we...

Its always a challenge to migrate to a new implementation and the new VM is no exception, we ran into several issues and are already hard at work fixing them. Currently resolved are: Issue 1149: ios.newVM causes exception on Calender.getTime() Issue 1151: array index out of bounds exception with ios.newV...

New builds sent for iOS will now use the new iOS VM by default, this will deliver a lot of new features: stack traces, 64 bit, xcode 6+ support, iPhone 6/6+ native resolution, no stall GC etc. We spent a great deal of time stabalizing the new VM but obviously it can't be as mature as our existing XMLVM backend and so it is quite possible that you w...

One of the common requests we get from users is more customization for the title bar area with more flexibility e.g. placing a TextField for search or buttons in various ways. Chen recently took action on this by introducing the new Toolbar API that replicates some of the native functionality available on Android/iOS and integrates with features su...
