One of the big issues with some new users who picked up Codename One was the lack of up to date device skins. We made several attempts in the past to improve this situation but these ended up as half measures at best. Last week we addressed some of the core problems that made it … New Skins, San Francisco Font and more

I really like the newer Rest API’s Chen added a while back. They are ultimately far more convenient than the ConnectionRequest API’s for most day to day development. In fact I used them almost exclusively in the Uber clone app. As a result of that I added a few useful enhancements and capabilities. If you … New Rest Calls

Device only bugs are the worse. You need to go through a device build and reproduce/rinse/repeat. Thankfully these bugs are rare but sometimes they just hit you smack in the face. One such problem occurred when I was debugging a transition on Android related to a login form. I would move between a Form where … TIP: Stop Editing

Every time we switch a version of xcode in the build servers things go haywire because of minor behavioral changes from Apple. Over the holidays we started a long and painful migration to xcode 9.2 which required an update to the Mac OS versions on our servers. Thankfully this wasn’t as bad as the old … Xcode 9.2 Mode

PWAs (Progressive Web Apps) are an extremely hot topic right now, and Codename One apps are very well suited to being deployed this way. In case you haven’t been following the PWA buzz, the idea is that it’s a web app that behaves like a native app. When they are first loaded in a user’s … Progressive Web Apps

The other day I sent out an email alert mentioning the Uber clone release and price change for the course on the 30th. I also mentioned upcoming modules in February which caught some attention. I wanted to clarify some things and answer some of the repeat questions I’ve been getting. I also have a lot … Uber Clone Clarifications and Xcode 9.2 Update

I’ve been so busy I just don’t have time to blog as much as I should. I do hope next month will be better in this regard (more on that below) but right now I have to make an important announcement. There are new chip vulnerabilities I’m sure you heard a lot about specifically Meltdown … Meltdown and Other Updates

We’ve just added support for Travis CI in your Codename One projects. Travis can be set up to automatically test your project (i.e. run unit tests) on a variety of different platforms every time you commit changes to github. There is a wiki page with full documentation of this feature, but the general idea and … Travis CI Integration

I hope you all had a great time over the holidays, I was working a lot but was able to enjoy the relative quiet of the holiday period to get some stuff done. There are a lot of new features I’d like to update you about and I will over the next few weeks (albeit … Uber Clone Trickling Down

Happy holidays, Merry Christmas, happy new year to all. All of us here at Codename One hope you have a lovely vacation if you are taking one. As I mentioned before we are still working but only partially due to the holidays. We still got a lot of things out and have a lot more … Updates and Happy New Year

I’ve been remarkably busy with the Uber clone application. Cloning Uber proved to be pretty easy but writing the material about it is much harder so I’m taking longer than I anticipated to finish everything. I’m already up to slide 200 and I’ve barely started…​ I think I might end up with more than 1,000 … Keeping Busy

Before I go into the details a quick announcement, we need to update some of our push servers. We will have a short amount of downtime on Sunday December 3rd around 8AM GMT. This update should be very fast and barely noticeable but it might impact some push message deliverability for a short period. Some … Updates and Holidays
