How you can Help Spread Codename One

I've written this in emails before and on quite a few occasions but this bares repeating. Gaining visibility in this industry is tough especially when the industry is driven by Google and Apple...
Despite years of effort most Java developers or mobile developers haven't heard about us and it's still an uphill battle for awareness.

Connecting to a MySQL Database from Codename One Part 2: Pure Java

In my last post I demonstrated how to integrate a MySQL database into a Codename One app using Xataface as a web service layer. In this installment, I'm going to demonstrate how we can build an equivalent app using a Java web service layer.

TIP: Cross Platform Update Available Strategy

One of the nice things in mobile development vs. desktop is the fact that updates are seamless. We supposedly don't need to worry about them and most newer OS's turn them on by default. This keeps are users with the latest version which is important, e.g. if we fixed a crucial bug or added a new monetization option...

Connecting to a MySQL Database from Codename One

In the following series of blog posts I'm going to shift some attention to server-side development in so much as it can complement a Codename One client application. In this post I'll demonstrate how you can combine a MySQL database, a web-service layer, and a Codename One client to produce a "Contacts" app. I'm going to steal the Contacts code from the Kitchen Sink demo for the UI, but I'll implement a different datasource that loads the contacts from a remote MySQL database instead of from the phone's internal contacts.

Fail Fast & Margin/Padding Performance

One of the frustrating parts in Codename One is builds failing in the cloud, the expectation is that a build that passes locally would pass in the cloud and that is something we strive to have at all times. One of the more commonfailures for new developers is due to refactoring of the main class or changing the signatures of the methods e.g. adding a throws clause to `start()`.

Properties

We usually just add a new feature and then tell you about it in these posts but properties is a special case and this post is intended not just as a tutorial but as a solicitation of feedback...
We committed properties as a deprecated API because we aren't sure yet. This could be a very important API moving forward and we want as much peer review as possible over this.

TIP: How to Ask a Question

I deal with a lot of questions every day and unfortunately most of them are phrased in a way that forces me to guess. There are some guidelines on how to ask a question but I think they are mostly pretty bad. Asking a question "correctly" helps you tremendously both in getting a correct answer faster and also in solving your own question. Following these three rules will significantly improve your questions

Native File Open Dialogs

Codename One has always provided access to the device's photos and videos via `Display.openGallery()` but it hasn't provided an API to open arbitrary file types because this type of functionality was not available on most mobile platforms. Times have changed and most platforms now offer support for more than just images and photos, so we decided to provide access to this functionality as a cn1lib. Here is a short introduction to the cn1-filechooser library.
