One of the common requests we get from users is more customization for the title bar area with more flexibility e.g. placing a TextField for search or buttons in various ways. Chen recently took action on this by introducing the new Toolbar API that replicates some of the native functionality available on Android/iOS and integrates with features su...

Our previous attempt at getting the new Lollipop behavior on Android OS 5 didn't go as well as we had hoped. While we can't find any device that failed we got a lot of community reports of various 4.x devices that just stopped working right after we made the changes recommended by Google. We tried to resolve them using several different tricks all ...

While the webservice wizard in Codename One is pretty useful for many things it still requires a proxy and Servlet container which might not be the right choice for everyone. Steve Hannah, created a pretty cool set of tools to map POJO's (plain old Java objects) to JSON structures by using compile time object mapping. This eliminates the costs/issu...

Building enterprise mobile apps can be pretty challenging especially when dealing with rapid changes, prototyping and corporate development requirements. One of the tools that has really revolutionized this field is Jenkins and related CI tools that allow developers to instantly track failures back to a specific revision of their code commits with...

I've had a lovely time giving a demo of Codename One at Codemotion Tel Aviv, one of the things that surprised me about the conference is that the sessions are so short (40 minutes) which gives very little time to actually get into code. So to fit both details about Codename One, Demo etc. and an app I had to narrow this down to the most barebone Co...

One of the problems in cross platform development is availability of functionality on one platform that is missing on another. Case in point sending an SMS message. Android, Blackberry & J2ME support sending SMS's in the background without showing the user anything. They even support a form of intercepting incoming SMS's to one degree or another (but that...

As we wrote before our new Garbage Collector is designed for amazing speed an never locks, this worked really well for most cases but we started running into weird crashes that took us deep into the seemingly simple GC code and exposed flaw in our "no locking" approach. It seems that our assumption that we can just mark all the static objects was f...

I've talked with many end users about their badly written apps grievances and I've come to the conclusion that it isn't a matter of native vs. cross platform or even HTML. Its a frustration issue, driven by unintuitive apps (hidden gestures etc.) and slow performance. The slow performance bit is the most misunderstood, there is a "feeling" of slug...

The last time we talked about the EDT we covered some of the basic ideas, such as call serially etc. We left out two major concepts that are somewhat more advanced. Invoke And Block When we write typical code in Java we like that code to be in sequence as such: doOperationA(); doOperationB(); doOperationC(); This works well normally but on the E...

Chen's been busy with some customers on a feature that is often requested: mailbox like swipes. This effectively allows you to swipe a component to the side in order to reveal capabilities underneath e.g. edit, delete etc. Using this capability is really trivial just use something like a a MultiButton and place it in a SwipeableContainer with the...
