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 through the migration. Please read this post carefully, I'll try to cover everything.Read More
A while back a question was asked on stack overflow How do you uninstall an extension using the CodenameOne Settings tool in NetBeans?Read More
We are thrilled to announce the release of Codename One 4.0 - Taxi. Codename One is an open source "Write Once Run Anywhere" mobile solution for Java and Kotlin developers!
This new release overhauled the way Codename One is updated, added support for Progressive Web Apps (PWA's), overhauled device skins & updated the backend iOS build tools. A major focus of this release is better support for peer (native) components, stability, unit testing and continuous integration.
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. I also found the comments very interesting so I'll go over the numbers/comments and provide my thoughts. If you think I misinterpreted the results please let me know...Read More
Codename One 4.0 (Taxi) will launch next week, to keep the code stable we are entering a week long code freeze. Please update your plugin installs frequently and report bugs immediately so we will have a stable release!Read More
A while back I introduced a MapLayout class as a tip and discussed the usage of this class. Since that introduction we ran into some scale issues as the layout misbehaved when a lot of elements were added to it. The crux of the issue is in the native map API which runs on the OS native thread and the Codename One API which needs immediate responses for layout.Read More
This is new behavior that went in without fanfare. If you created a new hello world app you might have noticed this. We changed the default boilerplate for Codename One and made it more representative of what you'd want to see in a hello world app.Read More
I covered the include source feature extensively. For the most part it's the simplest way to debug an application directly on the device. When I made that video the current version of Android Studio and Gradle were much older. We still use API version 23 on the build servers to keep everything compatible but you might want to use a newer version of the IDE.Read More
Last week I mentioned we are considering postponing the release planned for next week. We eventually did just that and the release is now scheduled for the 20th with code freeze on the 13th. So far we didn't change future release dates but there might be a cascading effect. As I explained before, this is an inevitable result of the migration to xcode 9.2 which is something we need to stabilize before the release.Read More
I promised 2 new course modules for February and just published the second one. In case you don't recall I discussed the first one here and it covered building Codename One applications from the open source code.
This new module goes through seven lessons that cover everything you need to know when building a performant app. It covers everything from generic performance tips/analysis all the way to profiling and a case study. You can check out the full module in the Deep Dive into Mobile Programming course in the academy.
