Keeping Busy

I've been remarkably busy with the Uber clone application. Cloning Uber proved to be pretty easy but writing the material about it is much harder so I'm taking longer than I anticipated to finish everything. I'm already up to slide 200 and I've barely started... I think I might end up with more than 1,000 slides in this module!

Updates and Holidays

Before I go into the details a quick announcement, we need to update some of our push servers. We will have a short amount of downtime on Sunday December 3rd around 8AM GMT. This update should be very fast and barely noticeable but it might impact some push message deliverability for a short period.

Clone and Run Codename One Demos In Single Line of Code

We have loads of demo Codename One apps hosted on Github, however cloning and running a project can be a little tricky because we generally don't publish the dependent jar files (e.g. CodenameOne.jar) in the Github repository. This helps keep the repository lean, but it adds some steps to the process of cloning and running the project.

I've been working on creating a clone of the Uber app for our upcoming update of the Build Real World Full Stack Mobile Apps in Java course. There is a lot to go through there but the basics are surprisingly easy.

Tutorial - What is Codename One

I published this video a while back but it was longer and a bit confusing (over 40 minutes). Since some developers watch it before getting into Codename One I thought it would be in order to streamline it into a more manageable length and transcribe the content like I did with the newer videos. I also cleaned it up a bit and the result is below.

Mac Appstore Builds & Device Farms

Steve has been pretty busy. We have new support for Mac Appstore builds as part of our desktop build process. That means you can build a signed Mac desktop app with Codename One which required a bit of work with previous releases. He also adapted our automated tests for Codename One so they would run on device farms and test against major versions of Android.

Codefreeze for 3.8

Codename One 3.8 should land one week from now and from later today we are effectively in code freeze. Please update to the release candidate of 3.8 tomorrow morning to help us track some last minute bugs and regressions. As is usually our process we will release updates as necessary with code reviews and next week we won't have the usual set of releases as we'll take some time off.

Tutorial - Working with Images and Densities

We had a lot of posts covering images, multi-image and density. It's one of the more challenging concepts to explain to developers coming from a desktop development background. Density is a simple concept to explain but the implications of it are sometimes counter-intuitive e.g. which device has higher density: Your phone or your 4k TV?
