In the previous section we went over the login with Google process, in this section we'll go over the login with Facebook. At this time we'll skip the "invite friends" option since that is blog post all on its own and we can just add that functionality to the completed application.Read More
We are thrilled to announce the immediate availability of Codename One 3.1!
Version 3.1 is the first release in our fast pace release cycle of 4 releases per year. It brings stability, bug fixes and great new features to the table. The biggest highlights of this release are support for Java 8 and simplified certificate generation for iOS. Check out the list below for more details.
In the second part of this tutorial we will cover the login process for Google and getting a unique id. We'll try to write generic code that we can later reuse for the Facebook login process. But first lets cover what "signing in" actually means...Read More
We just entered code freeze preparing for the release of Codename One 3.1. This is a one week freeze that is scheduled to end on July 28th after the release of the new version. In the next week we will only be working on critical bugs for stability and won't add new features.
After the release of 3.1 we will start aiming for 3.2 currently scheduled for the end of October as part of our new 3 month release cycle.
In this tutorial we will cover the basics of building a good looking chat application with Codename One that will work on all mobile OS's. We will cover everything from design to social network login and the actual chat behavior.
This project is created with the new Java 8 support to make the code simple and short. This tutorial is for a hand coded application mostly because GUI builder tutorials require video and are thus less searchable.
Its been a busy month and getting busier by the moment, we are preparing for App Engines suspension of its blobstore service which will be coming around soon. This effectively means older crash report email functionality will be stopped for older apps (just rebuild the app for the emails to work again).
We are also getting ready for Codename One 3.1 which we have tentatively scheduled for July 27th. This release will include a weeks worth of code freeze and will be the first of our new policy for faster release schedules.
So you have finished your app and tested it on the simulator. Everything looks good. You're now ready to proceed with testing on your iPhone. You select the "Send iOS Debug Build" menu item and wait for the build server to work its magic, but then you're faced with a notice that iOS builds require a valid certificate and provisioning profile. What a hassle!Read More
When we introduced Codename One initially we limited the API to CLDC level which is roughly a subset of Java 1.3, we then added support for a subset of Java 5 and we are now adding Java 8 language features!
Thanks to some work from Steve and the great work done by the guys from the Retro Lambda project we were able to add compatibility to the major Java 8 features, most notably lambda expressions. This is highly experimental and some features might not work but so far it seems things are functioning rather smoothly.
Facebook & Google login have been a source of a bit of pain mostly because of the obtuse and confusing documentation from both companies. Chen spent some time writing up tutorials for both Facebook Login & Google Login that should help you get started with applications that use such login options.Read More
Eric Dodji Gbofu has been working on a Codename One book in French for the past year and it finally came out!
I'm still waiting on my copy mostly to show to French speakers we meet (I have a very hard time picking languages), I'm pretty sure its a cool book. Chen and I wrote the forward for the book, I trust Eric did a great job in it just like he has done with Codename One Fr.
You can order the book either directly thru the publishers site (which is apprently the preferred way) or thru Amazon.
