iOS 7 Support
Apple just announced iOS 7 support the other day and it includes quite a few UI changes. We are already working full speed at incorporating support for iOS 7 before the general availability of the OS and have already released an initial skin through the OTA download feature (it will only work properly with the next plugin update).

Walk-thru Tutorial
Codename One Maker is a pretty elaborate app, there is only so far we can go with simplifying the app itself. So we added a tutorial mode which is common in mobile/web apps, to walk the user through the process of creating a...

Bouncy Castle Crypto API
We've got many requests in the past year for a cryptography API, initially we thought about adding something like this to the core but it seems somewhat niche so we decided to wrap up this great open source project and re-package it as a CodenameOne lib

When A Dialog Isn't A Dialog
One of the things we've been working on with Maker is getting the new GUI builder to support hierarchies/layouts which should be landing tomorrow or so. When we initially built the GUI builder within the Codename One designer we made many mistakes but one of the big ones was with layouts...

Maker: On Device Drag & Drop GUI Builder + External 3rd Party Plugins!
The PC isn't going away tomorrow but I think we took a major step in reducing the need for it when building some applications in the upcoming version of Maker. We just launched a very preliminary preview of our new Drag & Drop form designer for Maker.

Drop It - Introducing Dropbox Integration
We are working on something exciting, more on that next week (hopefully). One of the things we needed was a way to access files on a device, e.g. images, etc. however this is a painful and fragmented subject.

Cloud Object Viewer
Working with the Cloud Object API can sometimes be difficult. The data isn't tabular and understanding the concepts such as indexes and scopes for such objects is pretty hard. To help alleviate this difficulty Chen built a tool right into the Codename One...

Pingjam: A New Way To Make Money On Ads
We have many interesting ways for you to make money using Codename One and pingjam is one of the most innovative ways we ran into. Pingjam ads are placed within the dialer window based on the number you are dialing to, e.g. you dial to purchase a pizza you might get an ad offering a discount for purchasing over the web!

J2ME, Feature Phones & Nokia Devices
Is J2ME dead or dying?
How many times have we heard this for the past 3 years or so? -
Turn It On (Or Off)
We just added a new On/Off switch to Codename One that should allow you to use this component which is very popular on iOS (and gaining some popularity on Android), this is a rather elaborate component because of its very unique design on iOS but we were able to accommodate most of the small behaviors...
-
OTA Device Skin Downloads
Chen has recently added support for a new OTA (Over The Air) skin download feature which allows us to give you more device skins while maintaining a relatively small distribution size, in fact we might shrink the distribution by removing some of the builtin skins into the new OTA download option.

Which Subscription Level Should I Choose?
From the many emails and discussions we have with developers it seems that there is a great deal of confusion regarding the differences between the 4 levels of subscription that Codename One is offering. I would like to explain the difference more succinctly by covering some of the cases and benefits we reached with various level of subscribers. There are generally 4 levels of subscription: Free, Basic, Pro & Enterprise. (note: there is also a corporate tailored license which is something completely different).

Windows Phone 8 And The State Of 7
A preliminary Windows Phone 8 build has been available on our servers for the past couple of days. But now I would like to discuss the architecture and logic behind this port which will help you understand how to optimize the port and maybe even help us with the actual port...

Combining Salesforce and Codename one
While investigating the possibilities within Codename One, I made a discovery that I would like to share with you via this short article. But first lets discuss SalesForce, it is a CRM platform. Which has an advantage of an open Web Service API enabling it for use with Codename One.

5 Tips for Gamifying Your Mobile App
Mobile apps are in fierce competition these days. There are over one million apps available in the different marketplaces and while a user may install a large number of apps on his device. Recent research by Flurry shows that users don’t use many apps for very long and in fact only 25% of the apps survive after 3 months.

Performance Improvements On iOS & Some Other News
The other day one of our pro users sent us an app he is working on (which looks great and will hopefully be submitted to the gallery), he was experiencing major performance degradation on iOS compared to Android. Initially I couldn't find anything wrong with the app so I started debugging and benchmarking the hell out of it.

Pull To Refresh & Several New How Do I videos

Hamburger Sidemenu
The title of this post might be a bit misleading... Hamburger? The Hambuger sidemenu is the menu style popularized by the Facebook app, its called a Hamburger because of the 3 line icon on the top left resembling a hamburger patty between two buns (get it: its a side menu...)!

Inspecting Components
One of my favorite things about working with Codename One is the GUI builder, it solves a lot of the headaches of handcoding/positioning elements into place especially when coupled with the Codename One LIVE! application. However, not all of us use the GUI builder and even when we do we sometimes end up writing code manually.

New Preliminary Library Support
We've just launched a new library project type for Codename One, this is very preliminary but we think this is pretty much the final direction we will take with the Codename One library support.

Why Oracle won't issue Java for iOS anytime soon
They say that today all companies are software companies. In less than 5 years all companies will be mobile companies. So why isn't Oracle "getting it", why aren't they on the iPhone, on Android and even Windows Phone?

How Do I?
Answering common question is what a FAQ is usually for, but usually that's just not enough. A common presentation tip is: "Show, don't tell". Which is why we launched the "How Do I?" section in the Codename One website...

Fonts Revisited
Fonts were a painful subject in Codename One, historically devices supported a very limited set of fonts and we were bound by said limitations. However, devices moved forward and finally we too can move forward to more reasonable font support.

Installing On A Windows Phone Device
We recently added Windows Phone support to Codename One, this allows you to build your applications as a Windows XAP application for installation on a Windows Phone device. Unfortunately of all the platforms we support (including J2ME and iOS) MS is the only company that chose not to allow standard OTA distribution so you will literally need a PC in order to install the application with a cable.
