64 bit & OSS VM

Post Image

Apple Just announced they will mandate 64 bit for all new submissions starting February 2015, luckily we are very prepared for that and we already support 64 bit builds in our new VM. This is a huge triumph for the architecture of our new VM which is very resilient to changes Apple might make in the future thanks to its pure C architecture. Our o...

CallSerially The EDT & InvokeAndBlock (Part 1)

We last explained some of the concepts behind the EDT in 2008 so its high time we wrote about it again, there is a section about it in the developer guide as well as in the courses on Udemy but since this is the most important thing to understand in Codename One it bares repeating. One of the nice things about the EDT is that many of the concepts ...

Migrating To Androids In-App-Purchase 3.0

Post Image

Updated: Originally this article referred to a system based on Display.setProperty for distinguishing consumable types. This turned out to be an issue in beta testing and was replaced with either a naming convention or build argument. Google announced a couple of weeks ago that Android's In App Purchase 2.x API will be retired soon and all code sh...

JavaOne Booth, iOS 8 Issues & More

I just published a LinkedIn article discussing the financials of a JavaOne booth, if you are a startup/vendor looking at conference booths I hope this provides some much needed transparency. I know that when we researched the issue the lack of information was very problematic. iOS 8 introduced a few regressions into Codename One which should now b...

JavaOne 2014 Trip Report

This is going to be a radically different trip report, we weren’t just talking at Java One this year we were actually presenting with our own booth and would probably do so again next year. Last year we tried to purchase a booth as well but were unable to get in contact with the right person at Oracle before the conference sold out (which was a sha...

CN1ML & JavaOne

Post Image

Shortly after introducing Mirah support for Codename One, Steve is back with something that is arguably even more impressive. Over the weekend Steve released a tool called CN1ML which is an HTML subset markup language that allows you to effectively build Codename One UI's with HTML. This isn't another embedded webbrowser or HTMLComponent, this is a...

Second Annual Wristband Donation For Oracle Employees

Post Image

At JavaOne/Oracle Open World the wristband allows you to attend the "appreciation event" featuring Aerosmith, Macklemore & Ryan Lewis and Spacehog. Unfortunately Oracle employees don't get the wristband that allows everyone to attend that event! So I'm personally giving away my wristband and we might get some additional wristband donations to give...

IOS 8 Installs & Customizing the Pull To Refresh

Post Image

One of our pro users alerted us to an issue with iOS 8 that might trigger a case where apps can't be installed OTA (Over the air, via QR or email links) and only installed via itunes. We didn't experience this issue ourselves but it seems to be affecting many developers (not Codename One specific). This is due to caching of package bundle ID's and ...

JavaZone Trip Report

Post Image

JavaZone is winding down as I'm starting to write this although I'll probably post this after the videos are up to reference some of the interesting sessions I saw. Unfortunately JavaZone doesn't post workshop videos so my workshop won't be available, but frankly it wouldn't have worked well in video since it was relatively interactive hence there ...

8 to 6+

iOS 8 and iPhone 6/6+ are nearly upon us and Codename One is ready for both! We've just added device skins for iOS 6 and 6+, notice that due to the very high resolution you might want to disable scrolling. Notice that those skins are ridiculously large and as such might trigger an out of memory error when you try to run. To fix this just go to the...
