This weekend we pushed out an update that also included new versions of the GUI builder and the designer. We didn’t update the plugins but we still think it warrants the 4.1 version moniker even though we don’t support it in versioned builds. Due to one of the enhancements we added in this update we … Version 4.1 and Launch Screen Storyboards

I’ve been working on the new Facebook clone app, I have a lot to say about that but I’ll defer that for now. One of the things that Facebook did is provide a different experience in iOS & Android. I wanted to replicate that by using a more iOS style back behavior in my clone. … iOS Back Command Behavior and Facebook Clone Update

I’ve been working on improved learning materials for Codename One. One of the problems with videos is that I can sometimes unintentionally drag an idea that can be explained with a single image. DPI is one of those ideas, I’m assuming most of you already understand it but even if you do, I think this … Tutorial – DPI Explained

I published two articles on MapLayout here and here. After all that work they are now effectively obsolete thanks to a new API in MapContainer that builds component placement directly into the map itself. Unfortunately the Google API doesn’t let us position components (native or otherwise) accurately as it pans the map. This creates a … Map Component Positioning Revisited

Timezones suck. Especially daylight saving. I don’t mind moving the clock or losing an hour of sleep as much as the programming bugs related to that practice.

I’m used to NetBeans but if I will ever switch it will be to IntelliJ/IDEA. It’s a great IDE. I just need to rewire the muscle memory of my fingers for it. The Codename One plugin support on IntelliJ should be as good as the NetBeans support as the code is very similar. There are … TIP: IntelliJ/IDEA RAM

When we introduced support for z-ordering of peer components in Codename One we listed two major targets. The first was already available: Map. The second was still pending: Camera. Our current Capture API is very high level and removes a lot of the control from the developer. In order to give developers a high level … Camera Kit – Low Level Camera API

A while back Google announced that starting in August 2018 they will no longer accept applications targeting API levels below 26. With that in mind we plan to migrate our builds to use API level 27 which brings with it a lot of great new features but will probably break some things as we go … Android Build Target 27 Migration

A while back a question was asked on stack overflow How do you uninstall an extension using the CodenameOne Settings tool in NetBeans? Unfortunately this isn’t automatic due to the way cn1libs are implemented. In some cases you need to uninstall a cn1lib if you no longer need its functionality and this is far from … TIP: Uninstall cn1lib

I already teased about the surprises I got from our annual survey results and there are still quite a few surprises but as more people filled out the survey some of the big surprises tamed and a lot of interesting results emerged.
