That's a Great Looking App

I talk to a lot of mobile developers or those who are starting out in the field and by far the number one problem is getting a refined sublime app. There are too many difficulties and pitfalls along the way and the end result is often "sub par" in terms of the UI you want to achieve.
We too bare responsibility for that. We focus too much on the technology and too little on making "gorgeous" easy. I want you to join me in changing that narrative...

Tutorial: Networking and Webservices

Networking in Codename One includes so many different options and some very complex capabilities. This tutorial doesn't cover all the options but it tries to clarify the logic of why we have both URL and ConnectionRequest. It also explains the socket API types and which one makes sense in which situation.

Restaurant App Builder

In the bootcamp we didn't build just one big app, we built two... Or infinity... The first app was a restaurant ordering system that allows you to pick dishes from a menu and add them to a shopping cart. The second app was an "app builder" that allows you to customize the first app and then generate a native app based on that for your specific restaurant.

Kotlin WORA for iOS (iPhone), Windows & Android

We received some interest related to Kotlin over the past couple of years and this has risen noticeably in the past month or so. Up until now we tried to be very focused on Java which is why we didn't add support to other JVM languages even though this shouldn't be too hard. But Kotlins similarity to Java and its special relationship to Android make it an ideal second language for us.

TIP: Don't Put Text Fields in Dialogs

Text input is a very special case. Besides mixing the native and Java code we also need to deal with the appearance of the virtual keyboard which doesn't act consistently across platforms. This creates many complex edge cases that are just as problematic on native OS platforms as they are in Codename One.

Tutorial: Storage, File System and SQL

Storage is one of the big subjects we can delve into and never come out. Even without going into offshoots such as parsing, networking etc. it's still a pretty huge subject. We tried to simplify a lot of these problems by splitting file system from storage in Codename One but this often caused a different type of confusion.

New Online Courses - Coming Soon

You might have noticed that I haven't been committing as much code recently. It's because I've been working on 3 new online Codename One courses. One of my main goals with the bootcamp was to improve my video skills and modernize course materials. I'm well on my way with both and created pretty exhaustive materials so far.

Clearable Text Field

A common request over the past couple of years has been to add a text field that supports a clear button in the end, we used to have a common answer on how this can be implemented but we didn't have an actual implementation builtin despite this being a relatively common request.

TIP: Don't Ask Again

One of my favorite things about Mac OS is something subtle that took me a while to notice: it doesn't ask stupid questions. If you delete a file on a Mac it goes to the trashcan immediately, no question. Even though other OS's copied the trashcan concept they didn't embrace it in the same way, most of them still ask whether you are sure about this action even though the action is reversible.

Tutorial - Properties

I've discussed properties a couple of times before but never in a condensed video tutorial like the one we have here. In this video we review the value proposition behind properties as a step by step process.
