Writing native code in Codename One is pretty simple, however one piece is relatively vague and that is the ability to call back from native code into the Java code. The reason we left this relatively vague is due to the complexity involved in exposing/documenting this across multiple OS’s/languages so we chose to document this … Native iOS Code Callbacks

We are making good progress on our new iOS VM and are starting to test a much wider range of apps. The VM is still experimental however many features that didn’t work such as native interfaces, build flags etc. should now function as expected and perform well. Build times are still longer than Android build … VM Updates & Webservices

The Facebook native SDK for iOS and Android is difficult. It layers a great deal of complex permissions and concepts that seem obvious for engineers in Facebook but not so obvious for the casual observer. In the past Facebook allowed you to just request a write permission and you would receive such a permission, however … Facebook Publish & Android Localization

We just updated the build servers with the latest version of the Codename One iOS VM. This is still a work in progress and there is no guarantee your application will work. However, you can start playing with this right now and you might enjoy some of the benefits including proper stack traces, faster builds, … Try The New iOS VM

iOS allows us to send a push notification to trigger a numeric badge on the application icon, this is something you could do with Codename One for quite some time although it was mostly undocumented. You could send a push notification with the type 100 and the number for the badge and that number would … Badges

One of the great features we’ve added to the new iOS VM is the ability to get proper stack traces without a performance penalty. This is actually pretty easy to implement in a performant way, every entry to a method just registers an integer number representing the method name and class name and every time … Changes & Stacks

For the uninitiated, ARC is Apple’s term for Automatic Reference Counting. Objective-C uses a reference counting scenario to collect objects which is pretty painful to work with. Personally I preferred C/C++’s manual delete/free to the Objective-C semantics. But a couple of years ago Apple introduced ARC in which the compiler implicitly inserts the retain/release reference … Beating The ARC

I’ve had some talks with rather savvy Codename One developers recently which made me realize that quite a few developers don’t truly grasp the reason why we have a separation between peer (native) components and Codename One components. This is a crucial thing you need to understand especially if you plan on working with native … Understanding Peer (native) Components & Why Codename One is so portable

If you haven’t yet filled out the developer economics survey please do so now! We are still short of 30 entries in order to get better logo placement in the released survey. This is important since the people who read these surveys are of a demographic that’s much harder for us to reach normally. It … VM Stats

If you read the article about the 7 screenshots of iOS you might have wondered whether you can just supply these screenshots yourself? Well, now you can. Our build server will now generate the screenshots only if they don’t already exist in the jar so you will need to create the right png images in … Screenshots and Graphics Update

You might have noticed things have been a bit quiet with new features recently. That is because we had a bit of a holiday around here and because we spent a great deal of time working on a new VM for iOS. This work is still ongoing and basic things such as the garbage collection … New VM

Up until now debugging location oriented applications in the simulator was a bit painful, there was no real way other than coding to a specific location and if you relied on specific GIS data you couldn’t easily debug that case. Chen was working with an enterprise customer and got fed up with that so he … Placing
