Just last week I mentioned that we wanted to get push working on Windows & we're pretty thrilled to announce that it's available already... This means that we now support push on pretty much any major device with the exception of the Safari web browser.Read More
This is pretty cool as push to the web is a pain with every browser taking a somewhat different route but with Codename One this will "mostly" work.
The Phoenix UI kit by Adrian Chiran is one of the best looking and most challenging template UI's I had to adapt in recent history. The breadth of the design is pretty challenging but it also has some elements that are really hard to adapt across platforms in a portable way.
In the previous template post I introduced a material design inspired theme. This time the theme I chose is simpler "cleaner" but not necessarily easier to integrate. I've had quite a few difficulties wrestling with Photoshop oddities (bugs?) that made this template painful, hopefully I've narrowed down the process enough so this should become easier.Read More
Generating a template from a PSD isn't hard but it isn't a trivial task either, in this recurring segment I will try to generate good looking Codename One templates from freely available PSD files. Since this requires some effort I don't think I'll be able to keep this as a weekly segment but I'll try to post such a template once every two or three weeks. If you know of a free PSD that you'd like to see as a Codename One app point me at it in the comments and I might integrate it in a future post!Read More
We are trying to improve the visibility of Codename One within search engines and as part of that we think we can also help you guys improve your visibility. When you submit your apps to the app gallery we provide dofollow links to your website/app store listings. We'd appreciate if you place dofollow links back to https://www.codenameone.com/ which you can place in a very hidden/unobtrusive way. This helps us increase our page rank and as a result will improve your page rank as we link back to you.Read More
We just released the first version of the open source CN1Cordova project on github. This means you can take a common Cordova/PhoneGap app, import it into NetBeans and build a native app using our cloud build servers without any changes!
Before we delve into the exact process of converting an app lets start by reviewing the exact benefits PhoneGap/Cordova developers can gain from Codename One. You can also check out the video tutorial and slides below.
A couple of weeks ago I created a simple social network app as part of the Codename One webinar. This app provided functionality similar to the Facebook app.Read More
Tuesday morning I held a webinar on Java mobile development using Codename One. First of all, I'd like to thank all who signed up and attended. Unfortunately there were some technical difficulties with the Webinar software that caused some major glitches. Double thanks to those who endured and stayed to the end. We've learned from this experience and we will do better in future webinars.Read More
Steve wrote a rather detailed appendix to the developer guide covering all of those options from startup splash screen configuration to servlet proxy logic. The build also generates a ready to deploy WAR file which should make setting this up on any Java servlet container a nobrainer.Read More
When Codename One packages applications into native apps we hide a lot of details to make the process simpler. One of the things we had an issue with is
getResource/getResourceAsStream both of which are problematic since they support hierarchies and a concept of package relativity.
That's a concept that is problematic in iOS, generally everything about file access within the bundle in iOS is a bit problematic to accomplish in a cross platform way because Apple tries so hard to "simplify" and ends up creating fragmentation for us.
As part of tracking a bug in iOS media playback Steve hit upon some code that recreated the OpenGL framebuffer pretty much all the time. This was there to allow device rotation to work, but was implemented incorrectly...
After this fix animations and UI is much smoother on iOS, if you notice any potential issues let us know.
This website/blog has gotten really long in the tooth, we would have replaced it ages ago but since the build server is so tightly integrated in the code the effort to migrate was just too big. So recently we finally made the effort and migrated large blocks of code to be far more generic and we are now working hard on moving more than 3 years of content to the new website...Read More
In the past we made several attempts at compiling Codename One applications to webapps, these were only partially successful. On the surface this seems relatively simple: just use something like GWT and the Canvas API to generate a web app. However, Codename One requires threads (for the EDT) and that's just not something you can really hide. GWT i...Read More
