Logged Versions

When we get a crash report one of our first questions is "when did you build this?".
The answer is often too vague to trace the specific version, so we end up with a mixture of guessing.

The main issue is that there are different version values. They conflict with one another. They can be confusing and they can be inaccurate.

Questions of the Week XV

We are on the final stretch of 3.5 getting ready for the codefreeze that will go into effect in the middle of next week. With that in mind we have last minute features we are trying to get out of the door and unfortunately had to skip some big tasks. One of the big problems is the iOS server migration which we couldn't fit into the schedule. The peer component changes made it to Android but aren't set as the default, this makes the most sense in the current state. We'll probably flip the switch to the new peer components after the release.

Featured App - Ana Paltel

Millions of Codename One apps are installed on devices every month. Most of them aren't in the gallery and are never featured in this recurring segment. We are looking for something exceptional in apps that we feature here and Ana Paltel fits that bill. It has a very polished UI and it is shipped by a major operator. It uses some unique Codename One features to boot making it even more interesting.

How I Chose my Replacement for Parse.com

When I first read the announcement that Parse.com would shut down on January 28th 2017, I went from disbelief (it’s probably an early April fool’s joke) to rage (how could they do that?!) to sadness (oh no! it was a great service) and finally to utter confusion (where do I go from here and what do I do with my apps - parse4cn1, two MVPs for clients and an upcoming rewrite of Medex for which I was planning to use Parse.com as backend?). A few months down the line, a lot has happened such as the release of the open source Parse Server (yay!) and subsequently the Parse Dashboard. However, I still had to decide what do with my apps and I guess you have to as well.

Scrollbars & Tooltips

One of the big decisions we made a while back was to build the new GUI builder on top of Codename One itself, we extended that decision three months ago with the decision to build the Codename One settings in Codename One and then deciding to make it the default preferences UI for all IDE's...

Alphabet Scroll

We got a lot of requests from developers over the years to do an iOS style alphabet side scroll. Some developers implements such scrolling but no one made it generic or contributed it back. So a recent stack overflow question got me thinking about how easy it would be to actually implement something like that and I decided to try...

Questions of the Week XIV

With the pending release and some important issues we decide to make a minor update to the plugin today to introduce some improvements. We want the GUI builder to stabilize so we can finally crown it as "the" GUI builder rather than as "the new" GUI builder. To do that we need you guys to use it and submit issues, we also need you to use the latest version...

Dynamic AutoComplete

With the fix for issue #1694 we can now have a moderately simple method of creating an AutoCompleteTextField that works with a webservice. This has been requested quite often and was quite frustrating to implement in the past it is now relatively simple with just a few lines of code.

How to Build a Clicking (Tapping) Game Tutorial

Over the weekend LokeHansen posted a new series of youtube videos covering the process of creating a game in Codename One. I really enjoyed watching them as his teaching style is far more accessible than mine (I tend to be overly technical without noticing).

Using the new GUI Builder

We had a couple of posts in the past about the new GUI builder but we didn't have a "how to" guide yet. In this post we'll try to go step by step over the process of using the GUI builder and understanding its inner workings. We'll also try to clarify conclusively the role the new GUI builder plays in the toolchain and the migrations process from the old GUI builder.
